What You Need To Know About Surface Roughness Testers

surface roughness testers

Surface roughness testers measure the surface characteristics of an object. This is important because the surface dynamics determine the usability of that product as well as factors such as durability. For example rougher surfaces are more likely to corrode and be subject to wear and tear than smoother surfaces. On the other hand, smoother surfaces are less likely to adhere to each other than rougher surfaces. During the manufacturing process, these instruments measure the surface characteristics of the manufactured part and compare it to a required ideal. Readings from surface roughness testers are often measured in units symbolized as Ra.

Inspecting Small Holes Is A Job For Air Gages

small holes air gages

Needles used to deliver fluids, fuel injection nozzles, and even aerosol cans are all examples of parts that use small holes for several reasons. Holes in nearly all of the aforementioned examples range from 0.1 mm to 1mm in diameter. To a layman, the holes may seem irrelevant. Experts will however tell you that in the medical field, that small holes used to deliver medicine or air to a patient can be the difference between life and death.  This means that precision matters a lot as far as these holes are concerned. Let’s find out how to properly measure them:

Getting Your Adjustable Bore Gage Settings Right From The Get-Go

adjustable bore gage settings

Comparative instruments, such as an adjustable bore gage, can feature an electronic readout or dial that displays the direction and amount of variation in the test bore, from the nominal size. If you are using adjustable bore gages this way, you need to set the gage to the required nominal size, to which the bore is to be compared. There are various ways to set the bore gage to the nominal size. The methods explained below can provide a balance of versatility and reliability, precision, and speed. Read on to find out which setup method will work best for you:

How Should You Approach Measuring Internal Grooves?

measuring internal grooves

Do you know that manufacturing a groove on a turned up part is actually easier than inspecting it? With this fact in mind, it is important to select the right measuring tools for internal grooves. Good gaging practice should always be maintained since grooves play a critical function especially for retainer rings and seal rings. There are different types of gages in the market that can measure grooves internally and externally. In this post, we will focus more on gages used to examine grooves internally. Let’s look at different types of gages used to measure internal grooves, their designs, and how they function.

Product Spotlight: Mitutoyo Digimatic Height Gage Series 570

Mitutoyo Digimatic Height Gage Series 570

Height gages allow an individual to measure the height of a workpiece. These measuring instruments often feature a slider with a measuring stylus. The stylus moves relative to a measuring scale that’s fixed onto a beam. Height gages are recommended to be used on granite surface plates or datum planes (that come with scribe part features). Today, you can find a wide variety of electronic and mechanical height gages on the market. They are indispensable instruments for quality control. In this post, you will find out more about an excellent height gage that can make measuring the heights of workpieces easier. Introducing the Mitutoyo Digimatic Height Gage Series 570. This product features an ABSOLUTE linear encoder that eliminates the need to repeatedly set the reference point at every power on. In other words, you will be able to avoid overspeed errors!

Depth gages typically consist of short-range indicating devices mounted through a plate or a reference bar. They are among the simplest indicator gages that are used in thousands of critical applications. Depth gages are used to measure the depth of recesses, holes, slots, counter bores, cavities, and other component features. Depending on the specific application, they are available in various configurations.

How To Simplify Gaging Processes

simplify gaging processes

At the most basic level, manual gages are designed to make it easier to stage and gage a workpiece, ensure the best possible performance for the measuring task at hand, and reduce operator error. With this type of fixturing, the technician does not need to expend a significant amount of effort and time to complete the task. Today’s manufacturing operations are fast-paced. Those operations are also based on short runs of precision parts and flexibility. That is why using a gaging system that matches the way components are made is highly recommended. Here are further ways to simply gaging processes:

How Should Manufacturers Approach Buying CMMs?


The Coordinate Measuring Machine, otherwise referred to as the CMM is a familiar tool in manufacturing facilities. It stands out as one of the most effective and reliable tools used in quality control. Used for three dimensional measurement and verification, CMMs come in different designs and of course brands.  This makes it hard for a manufacturer with little or no knowledge on CMMs to buy one.  There are however, factors that can make the whole buying process easy. Such factors include:

Gaging For SPC Made Simple

gaging SPC simple

Much has been said and written about statistical process control, commonly referred to as SPC. Shop owners seem to keep off the process, citing reasons such as how expensive SPC gaging equipment are or how small their facilities are. These two reasons can best be termed as misconceptions. SPC is not as complicated as most people think. Secondly, you do not need complex computerized systems and costly software to get into SPC. You should therefore benefit from gaging for SPC, as much as your competitors do. But before that, here is how to simplify the whole gaging process.
