When it comes to precision manufacturing, measuring the dimensions of shafts and other rotationally symmetrical workpieces accurately is a must. With increasing demands for smaller features, tighter tolerances, and faster production times, choosing the right shaft measuring tools can significantly impact the quality control process. In this guide, we’ll discuss key considerations for selecting professional-grade shaft measuring tools and explore some top models on the market.
Types of Shaft Measuring Tools
Before choosing a shaft measuring tool, it’s important to understand the different types available. Shaft measurements often require high precision for features like diameters, lengths, grooves, keyways, and threads. There are three main categories of tools for this purpose: optical, tactile, and combination systems.
- Optical measuring tools use light to assess the surface of a shaft. These are fast and efficient for measuring external features like diameters, fillet radii, and chamfers.
- Tactile measuring tools involve physical contact with the shaft’s surface, providing highly accurate measurements of internal features such as threads, grooves, and keyways.
- Combination systems incorporate both optical and tactile measurements, ideal for shafts with complex features.
Depending on the application and part complexity, you may need one or a combination of these systems to meet your measurement requirements.
Accuracy and Precision Are Key
When selecting shaft measuring tools, accuracy is paramount. In many cases, shafts are used in safety-critical applications where even slight measurement errors can lead to serious issues. Look for tools that offer high repeatability and the ability to measure within the tolerances required by your industry.
For instance, the Mitutoyo Shaft Measuring Unit is a well-known tool in this space. It measures diameter, total indicator runout (TIR), length, and straightness with high precision, ideal for industries where reliability and accuracy are non-negotiable.
Consider the Speed of Measurement
The speed at which a shaft measuring tool can take measurements is another important consideration, especially in high-volume production environments. Faster measurement times from instruments like the Marposs Quick Set can lead to improved throughput and less downtime in production.
Ease of Use and Operator Interface
The ease of use of a measuring tool is another important factor. A tool that requires minimal setup and is intuitive to use will help reduce the chances of human error and increase operational efficiency. Many modern shaft measuring systems come with user-friendly interfaces that allow operators of varying skill levels to perform measurements confidently.
By way of example, the Fowler Sylvac SCAN S25T offers high-speed scanning capabilities while being easy to operate. This system is equipped with a touchscreen interface, making it user-friendly for both experienced operators and those new to precision measurement. Its scanning technology enables fast, accurate measurements of various shaft features, and its intuitive design makes it a great choice for companies seeking an efficient, reliable tool.
Versatility of the Tool
Consider the versatility of the shaft measuring tool. Some tools are designed to measure specific types of shafts or features, while others offer more flexibility across different part geometries. A versatile tool can save you money in the long run by serving multiple purposes and adapting to different production needs.
Consider Software Integration
Many modern shaft measuring tools come with software that integrates with your existing quality control systems. This software can automatically process the measurement data and generate reports, streamlining the workflow and improving data consistency.
Look for systems that allow easy integration with CAD software or coordinate measurement systems (CMS) to ensure a seamless workflow from measurement to analysis.
