Top Mistakes To Avoid When Using Thread Gages

Thread gages are used for a wide variety of industrial operations and can be considered as equipment that is essential. As an owner of a thread gage, it is important to note that maintenance is necessary in prolonging its lifespan and productivity. However, it is very common for serious mistakes to be made when using thread gages that can affect the efficiency and condition of the equipment. Ensuring that you avoid these mistakes can help you to prevent any malfunctions of your thread gages. Here at Willrich Precision Instruments, we provide a wide variety of different precision instruments that are made with the finest materials and guaranteed to withstand the test of time.

Exposure to Temperature Extremes when Storing Your Thread Gages

Obviously, as a precision instrument, the most important thing to maintain in a thread gage is its precision. Thread gages are made using metals that can be sensitive to temperature and can either expand or contract depending on the extremes. This change in size of the thread gage can compromise the precision of the thread gage. Thus, you should only store your thread gages in a storage area that is not affected by the extreme temperatures as the result of the climate. Additionally, make your best effort to store your thread gages in a place where there is as little humidity as possible in order to prevent rust from ruining the quality of its performance.

Allowing Your Thread Gages to Become Dirty

The dirt that gets trapped in between the parts of your thread gage can negatively affect its functionality and can decrease the precision of the instrument. Therefore, it makes sense to schedule regular cleaning of your thread gage so that proper maintenance of the parts is carried out. Additionally, in the industrial environment, workers’ hands can become contaminated with oil or other substances that can affect the performance of the thread gages as well. As such, thread gage operators should be trained to clean their hands before touching the thread gages so as to prolong the life and increase the efficiency.

Failing to Lubricate Your Thread Gages Adequately

Lubricating your thread gage is essential in preventing any corrosion of the parts. This also ensures that the entire system works seamlessly. What you can use for lubricating your thread gage includes oil-based easy-peel wax coatings.

Not Keeping Track of the Accuracy of Your Thread Gages

It is inevitable and only natural that your thread gages become less accurate over time. This would require you to regularly recalibrate the thread gage and document the changes of its accuracy. Ensure that the dates which you carry out the recalibration are documented properly and that the schedule is in line with the recommendations of the manufacturer.

Not Training Your Thread Gage Operators

The easiest way to make sure that your thread gages are treated and used in the right way is to give your employees who operate the thread gages proper training. The training should encompass how to use the equipment and also how to engage in proper maintenance so that it can stay efficient for years to come.

Whenever you have new employees, it is always wise to give them proper training as to what the right storage methods and maintenance procedures are. Be sure to hand out manufacturer manuals so that they can learn how to avoid malfunctions and engage in proper safety procedures as well.

Things You Need To Know Before Choosing An Ultrasonic Thickness Gage

Before you choose your ultrasonic thickness gage, you have to consider a number of factors. Some of the obvious factors include your budget constraints and also the reason you are buying it for. However, if this is your first-time purchasing equipment like this, then you might not be familiar with some of the other factors which might not be as obvious. It is important to note that these factors might be equally worth considering when choosing an ultrasonic thickness gage from such a competitive market. Furthermore, there are many factors that you need to consider when talking about the application of the instrument.

Before choosing the one that you want to get, you should find out exactly what you can and cannot do. Here at Willrich Precision Instrument, we provide a wide range of metrological products for any of your industrial needs.

Ultrasonic Thickness Gages Explained

Ultrasonic testing to measure thickness is becoming a very popular method. The main reason for using this device is that it can test the thickness of a wall without any form of destruction. It is usually used for the detection of thinning walls as a result of corrosion or as a method used for quality assurance. It can also be used for measuring boilers, aircraft materials, and even pipes.

The market for ultrasonic thickness gages is extremely competitive and there are many different manufacturers. The entry-level handheld units might cost as low as a few hundred dollars and can reach up to thousands of dollars. Usually, the software used for such products are very similar, but manufacturers can alter the internal software to cater to more specific needs. Many companies around the world offer the option to upgrade their products. As a result, a simple thickness gage can be upgraded to a device with datalogging capabilities and live waveform features.

The Material of Your Ultrasonic Thickness Gage

It is essential that you also list out the materials and the range of thickness for each material that you might want to test. Additionally, you should note down the accuracy that you want to achieve, the temperature when you are taking the readings, and the finish of the materials. In the case where a fluid can be applied to it, the fluid is most likely soluble in water and suitable for use with high frequency sound waves.

Considering the Weight and Size

When contemplating which model to purchase, some factors that you should consider include the weight and size of the ultrasonic thickness gage. Firstly, you must check if you have sufficient storage space for the size that you are looking for. Some ultrasonic thickness gages are compact and portable. They can even fit inside your pocket because they utilize AA size alkaline batteries that everyone knows are extremely portable.

On the other end of the spectrum, there are much larger gages because of the battery that they use. For example, if you need long-lasting battery life that uses latest lithium ion technology, then chances are your unit will be much larger. Additionally, you should consider how easy it is to service the unit that you want to buy, bearing in mind the place of manufacture and their reputation in this industry.

The Four Main Types Of Coordinate Measuring Machines

If you have no prior knowledge about coordinate measuring machines, then this article is for you. In the current market, there are four main types of coordinate measuring machines. These include the bridge, cantilever, gantry and horizontal arm coordinate measuring machines. They all have their own advantages depending on the components that you want to measure. Here at Willrich Precision Instrument, we understand that buying a coordinate measuring machine might not be as simple as you think. There are many types and factors to consider. However, we provide a wide variety of precision instruments for any of your industrial needs.

Bridge Coordinate Measuring Machines

Bridge machines have become increasingly popular over the years. This type of measuring machine allows for probe movement along 3 different axes, X,Y and Z. The unique thing about this machine is that each axis contains a sensor that can judge the position of the probe on any particular axis. It is capable of doing this with micro-meter precision. The bridge machine produces something called a “point cloud” which is done by sampling the three sensors and measuring a particular point on the object.

They have a very simple structure and is easy to use. Bridge machines are also cheap to manufacture and can withstand the test of time by maintaining accuracy consistently. Usually, bridge machines are fixed on a precision granite plate and have two legs to support the carriage. It is interesting to note that a typical bridge machine is only driven on a single side while the other sides are allowed to float freely. Close to 95% of them utilize air bearings so that there is greater ease of movement.

Cantilever Coordinate Measuring Machines

The cantilever coordinate measuring machines are typically used to measure smaller parts. In comparison to the bridge machines, they grant access to the user on three different sides. They also only allow for probe movement on X and Y, creating limitations on the size of the X beam. The rigidity of the machine makes it only suitable for measuring smaller parts. This type of machine will work well in a shop-floor setting because it has automatic loading and unloading capabilities as well.

Gantry Coordinate Measuring Machines

This type of machine is made specifically for measuring parts that are larger in size and heavy in weight but require the precision of a bridge coordinate measuring machine. Typically, gantry machines work best mounted to the floor. Thus, it is important that you provide it with a solid foundation. The smaller machines utilize four upright columns that support the Y-axis beams. On the other hand, larger gantry machines have 6 to 8 columns in relation to the length of the Y-axis.

Horizontal Coordinate Measuring Machines

The horizontal arm machine was first manufactured in Germany and were originally used as scribing tools. The first models were operated manually and were much harder to use as compared to today. The horizontal arm machine is different from the other three types in the sense that is has 2 axes mounted on a saddle that moves up and down the horizontal axis.

Choosing The Right Hardness Tester For Your Needs

Hardness testers are essentially devices that can accurately tell you the hardness of a certain material. This is done by taking into account the effect that an indenter (usually made from hard steel or diamond) has on the surface of the material. The depth of the penetration into the material is measured and from this the hardness can be taken. Here at Willrich Precision Instrument, we understand the difficulties one might face when choosing a hardness tester because of how many different types, brands and models there are in the current market. We specialize in hardness testers and other high-quality metrology instruments that can suit the industrial needs of all our clients.

The Different Kinds of Hardness Testers

In the current market, there are two main types of hardness testers. They can either be bench hardness testers, also known as stationary or classical hardness testers. On the other hand, they can be portable hardness testers, more commonly known as mobile or electronic hardness testers.

Bench Hardness Testers

As the name suggests, this is a very classic hardness tester that can measure the hardness of materials using traditional methods such as Brinell, Vickery or Rockwell. Usually, when you are looking for a hardness tester that uses the Vickery method for example, it will be called a “Vickery bench hardness tester”. As the word “bench” suggests, there are also some bench top hardness testers in the market that can allow the user to measure the hardness by a few different hardness scales. There are actually some hardness testers that can measure with a combination of scales. All bench top units are big in size and can be very heavy, with some models being over 50 kilograms. They have to be mounted on a table or the floor, which allows for easy measurements using the direct method.

Portable Hardness Testers

In contrast to the bench hardness testers as mentioned above, portable hardness testers are obviously much smaller in size. They are also much lighter in weight. Additionally, being much more compact than bench hardness testers, they can measure the hardness of your materials with some scale violence. There are several advantages to using portable hardness testers. For example, you can bring the device with you easily from home to the workshop to measure the materials that you want to test.

Portable Hardness Measuring Instruments

These are also portable like the testers, but the main difference is that they are electronic devices. What this means is that there is usually a larger range of features that you might not get with an analog device. For example, you will be able to save the results on the device’s internal memory. This would greatly increase the convenience for users because the measurement results can then be transferred to a computer so that reports can be created. The reports can be created using specialized ARM control programs that are more common in portable hardness testers. However, there are very rare cases where some tests can only be carried out by bench hardness testers. In all other cases, portable hardness testers work just fine.

Why Hardness Testing Is Essential

The hardness of a material is its inherent property that allows it to withstand abrasion, bending, scratching, cutting or deformation. If your day to day work involves materials manufacturing, you are most likely aware of the importance of a hardness test in allowing you to evaluate the products received from external suppliers and also, the production process of internally manufactured products.

Baseline measurements have to be defined and set in place in order to make sure that your products meet the required quality specifications in terms of strength. However, if you are new to the field, you might be unaware that the hardness of any material is not an intrinsic property but rather, the value obtained from a hardness test stems from a specific measurement sequence. Read on to find out more about hardness testing and how it can be performed!

Types Of Hardness Testing

For many materials in the 21st century, a hardness test comprises of using a device that impacts the material with a defined amount of force over a specific amount of time before measuring the depth of the groove left behind. The commonly used hardness tests that measures the relationship between hardness and the depth of the indentation can be classified into the Rockwell, Brinell and Vickers hardness test.

Rockwell Hardness Test

Rockwell hardness tests is one of the most commonly used hardness tests in the market due to its fast speed and high accuracy in determining the hardness of numerous materials such as metals, plastics and allows. When conducting this test, a hardened steel ball indenter or a diamond cone would be pushed into the material with a test force of 10kgf. Upon attaining equilibrium, more force would be used in order to cause a greater indentation depth. Once equilibrium is reached again, the force is removed, and the permanent depth of the indentation made would be used to determine the Rockwell hardness number of the material.

Additional Benefits Of Hardness Testing

By conducting a hardness test, the results obtained can be used to predict and determine the extent whereby the tested material can perform under various conditions. For example, by measuring the hardness at various temperature and humidity conditions can simulate and allow you to know if the hardness of the material would be impacted by storing it in a humid warehouse. If the hardness measurements remained constant, it indicates that the material can be stored normally. Otherwise, special precautions must then be taken to ensure proper storage of the material. Another instance would be testing the material’s hardness under prolonged exposure to various chemicals. This would allow you to determine the material’s resistance to chemicals and if special caution needs to be taken to ensure the functionality of the material is not affected by a chemical exposure.


All in all, a hardness test is a crucial test that you must adopt in ensuring that your product meets the stated quality specifications.

Understanding Bore Gages

A bore gage is an instrument that is frequently used to measure the internal of a hole. It is also known by many names such as bore mics, hole tests, holtests, internal micrometers or cylinder tests depending on your geographical region. It operates on the basis whereby parts known as the anvils expanding outward in order to determine its diameter when inserted into the hole. Read on to find out more about the characteristics and uses of bore gages.

Types Of Bore Gages

There are numerous types of bore gages in the market, with the more common types being bore gages with two or three anvils respectively. Bore gages with two anvils are cheaper and are calibrated with gauge blocks whereas those with three anvils are known as internal micrometers and are calibrated with setting rings. Both types can make use of either a digital or dial scale to display the measured diameter of the hole. Apart from the common bore gages, there are also more specific types specializing in various measurements, such as the dial bore gages, small hole gages and telescopic bore gages.

Sizes Of Bore Gages

Depending on the diameter of the hole that you are measuring, you would require different types of bore gauges that have various measurement sizes. If you are looking for a bore gage that can measure a wide range of sizes, an adjustable bore gage would be the equipment that is suited for your needs! However, this type of gage suffers from a lower tolerance in the measured diameter. If a high degree of accuracy is demanded in the final product, plug gages, which comes in fixed sizes would be the equipment that you have been looking for. Plug gages can be customized accordingly to your requirements, making them available in both small and large sizes.

Uses Of Bore Gages

With the high level of precision obtainable in a bore gage, there are many applications where it can be used such as the measurement of pipes, holes and cylinders, which are commonplace in the manufacturing, automotive and equipment calibration industries. Inspectors and maintenance staffs utilize bore gages to inspect the dimensions inside injection moldings to ensure that its quality are up to the desired standards, or in extruder barrels to monitor wear and tear over an extended period of time to find out when preventive maintenance can be carried out. Mechanics and machinists also make use of these equipment to detect the extent of wear and tear in cylinder heads and also to accurately measure holes in an engine block to ensure that the pistons fit tightly to prevent any gas leakages.


With the numerous potential applications of bore gages and its ease of customizability in terms of types and sizes, it serves as a handy tool that can greatly assist you in the measurement of a hole’s internal diameter.

A Short Course On Measuring Pitch Diameters

Do you know that bolts, tapes, dies and other helically threaded components are characterized by various parameters? These parameters include depth, angle, pitch, major and minor diameters, whereby the pitch diameter holds the most significance amongst these parameters. Read on to find out more about the importance and the process of measuring pitch diameters!

What is a Pitch Diameter?

To many of us, the effective diameter, also known as the pitch diameter, refers to the diameter of the cylinder as it cuts the midpoint of both the major and minor diameters known as the pitch line. The pitch diameter is an important property that governs the compatibility between two threaded parts, such as nuts and bolts and if they can be successfully mated with each other. Moreover, they are also used as a crucial reference for other relevant thread measurements.

Measurement of Pitch Diameter

Due to the large susceptibility of pitch diameters to measurement errors, unique measuring equipment must be used in order to obtain an accurate reading. Although there exist many types of techniques to measure pitch diameter, there exist three most commonly utilized methods, namely the three-wire measurement method, the optical comparators and specialized micrometer screw gages which ensures the accuracy of your reading!

Three-Wire Method

The three-wire method makes use of a traditional, flat anvil micrometer screw gage to measure pitch diameter. Three separate wires of pre-measured diameter would be placed within the pitch of the threads before the gage of the wire is chosen. This enables the wires to stay in contact with the pitch line while simultaneously extending beyond the outside diameter of the thread. With another micrometer screw gage, the distance between the wires on the opposite sides are measured and used as inputs in prescribed formulas to derive the pitch diameter.

Optical Comparators

Optical comparators make use of the fundamental basis of optics and light to determine the pitch diameter. A magnified silhouette of the threaded object is projected on a screen and a specialized software would be used for image analysis and to obtain the pitch diameter. Through the use of optical comparators, it would result in a high degree of accuracy in pitch diameter measurements. However, a downside of it would be its expensive cost!

Specialized Micrometer Screw Gages

A commonly used instrument would be a form of micrometer screw gage known as a thread mic or a pitch mic. It was designed for the purpose of measuring the pitch diameters of cutting threading tools. To make use of this instrument, the ratchet of the micrometer is turned continuously until the spindle comes into contact with the thread flanks. The pitch diameter can then be read off from the micrometer scales. This method provides an efficient and accurate, but yet a low-cost way of measuring the pitch diameter!

A Guide To Measuring Surface Finishes

The finish, or surface texture of a finished component can be viewed differently from two different perspectives. For the designer, variations of surface texture would affect the functionality of the component. If the designer wishes to change the component’s functionality, the surface texture specification must be altered. From the machinist’s point of view, the finish is the end product of the manufacturing process and it can be altered by modifying the manufacturing process. Read on to find out more about measuring surface finishes and the various parameters involved!

Variations In Surface Finishes

Surface finishes contains the troughs and crests that comprises the surface and the direction of the surface. Through the usual machining processes such as grinding, milling and turning, uneven sections are being imparted onto the component’s surface. Moreover, other factors such as the vibration, speeds, condition of the machine tool and the choice of machine tool can also affect the extent of these irregularities. As a result, these factors must be carefully controlled.

Components Of Surface Finishes

Surface finishes can essentially be classified into 3 segments:

  • Roughness: Roughness stems from the usage of cutting tool that leaves a mark with a distinct depth and width. Also, in the cases of grinding, the abrasive granules on the wheel can also leave a groove on the surface of the component that is being produced.
  • Form: Form can be attributed to a lack of straightness or flatness in the machine’s cutting tool, resulting in the component’s surface finish being affected. This results in a systemic deviation from the specified requirements whenever the machine is being used.  
  • Waviness: Waviness of a component is defined as small variations in the length between the cutting tool and the produced component during the manufacturing process. These variations are caused by the instability of a cutting tool due to vibrations. The source of vibrations can be internal such as the motor of the machine or even externally induced due to the operations of other machines nearby. The waviness of the component can be measured by a contour measurement device.

How To Measure Surface Finishes

All of the above-mentioned surface finish components exist simultaneously and each condition is checked
separately. By measuring these components, the search for the origins of the error can be narrowed, allowing its effects to be reduced or eliminated. There are many instruments available in the market that would enable you to measure these 3 components, such as a pocket-sized, battery-powered gages. Its low price allows for the measurement of a small number of roughness parameters at an affordable cost. Furthermore, these instruments are also very flexible and are very easy to use. If you require more complex parameters to be measured, more precise equipment but expensive that involves powerful computers would be required!
