CMM Probe and Measurement

Quality Control Systems

Are you looking for used CMM probe? Quality control systems rely on accurate measurement and data collection. Though there are many ways to measure parts, a used CMM probe is often the best way to meet customer requirements. At CNCMachines.net, we offer dependable CMM’s for a wide range of part measurement applications.

Over the years the coordinate measuring machines (CMMs) have been replacing traditional inspection methods. A used CMM probe can reduce time and effort needed to inspect special features such as gears, camshafts, airfoil shapes, and many others. Traditionally, special features like these required specialized testing equipment.

Delivery Quality Parts with a Quality Used CMM Probe

Product quality depends not just of the quality of machine tools for manufacturing, but on the accuracy and repeatability of the measuring and inspection devices. Even if you have a low cost, low-performance machining center, if you have a high-quality CMM, you can guarantee delivery of quality parts. However, if you have a high-quality machine tool and a low-quality CMM, your quality can be compromised. Quality control systems which rely on CMM data are more reliable than other more manual types of inspection.

Selecting a Used CMM Probe

  • Size: The first thing to consider when purchasing a used CMM probe is size. We recommend considering a CMM with twice the X, Y, and Z measuring ranges as the part width, length, and height that you need to measure. This way you will have space for extensions and fixtures if needed in the future.
  • Required Uncertainty: Different CMM equipment conforms to various performance standards. You can learn more about the standards in ISO 10360-2. ISO10360-2 is an international standard that specifies two uncertainties: volumetric length measuring uncertainty (E) and volumetric probing uncertainty (R). These are things that you can test for when inspecting a used CMM by using gage blocks or a step gage. When you are comparing CMM’s from different manufacturers, make sure you compare like specifications. Other standards you may find include CMMA, VDI/VDE 2617, B89, and JIS.
  • Software: Some CMM’s come with software for measuring complex geometries such as impellers, screw compressors, hob cutters, and bevel gears. Make sure you understand the complexity of your parts and know that the specific used CMM probe has the software capabilities to measure it.
  • Throughput: Consider how many parts you will need to inspect daily. The more parts a CMM can inspect in a day, the lower the cost per part. Look for the acceleration rates and the number of probing points per minute, which can determine overall throughput. Sometimes special fixturing arrangements can increase throughput as well.
