Detection method of precision parts processing

by:Yifeng Metal     2022-04-29

When machining precision parts, the roundness measurement method and the two-point method and the three-point method can be used for testing. The circularity law is to put the measured part on the worktable of the circularity meter, find the center line of rotation, and make the circularity meter probe contact and rotate with the inner hole of the workpiece. Based on sensors, amplifiers, filters, measurement power circuits, and finally display accurate measurement results. If the output is a specific contour map, the inscribed circle template can be used, and the radius difference between the two tolerance circles in the same boat can be used as the roundness error of a certain section. This instrument is suitable for components that require high measurement accuracy.

Which is better for precision parts processing


If the measured contour is a circle with odd edges, it cannot be used The roundness error is measured by the two-point method, and the three-point method can be used for accurate measurement at this time. Use the V-shaped bracket to support the workpiece to be tested, and use the indicator to measure the larger error generated by the product workpiece rotating one cycle, and take it as the roundness error of the section. Commonly used V-shaped crossing angles α are 60 degrees, 72 degrees, 90 degrees, 108 degrees and 120 degrees, respectively. The three-point method can also be used for high-precision precise measurement in precision parts processing.

The above is the detection method of precision parts processing. I hope it will be helpful to you after reading it. If you want to know more about precision parts processing, welcome Consult customer service online or call our service hotline.
