How to measure mim parts
1, the outside diameter measurement method: use vernier caliper or two projector measurement
2, the inner diameter of the measurement method: the use of needle plug ruler or two projector measurement
3, with standard thread ring gauge measurement
4, the measuring method of the internal thread, the external diameter of the internal thread is tested with the thread plug gauge (through gauge), and the middle diameter is tested with the thread plug gauge.
5, the surface roughness detection using sample block comparison method for comparison and judgment.
6, flatness test: the use of meter detection, the plate placed three adjustable support, the parts measuring face placed on the supporting point, adjust the supporting point, so that the three points of height, the peak valley value measured by the meter is the plane flatness error.
7, surface color inspection: visual inspection, with the standard color block for comparison
8. Overall deformation test: test with the assembled tester provided by the customer or the self-made tester
