How to judge the quality of the processing center
The roundness test roundness, there is a small complex surface test machine in dealing with the stability of the large amount of time.
It is best to take a workpiece to test, the conditions permitting to get a workpiece under the test, the workpiece must have a few shapes, there must be a continuous surface trial surface finish, there is a quadratic experimental positioning accuracy, there is a big
There are several aspects of the machining center: the rigidity of the machine, the rigidity of the shaft, the positioning accuracy of the X, Y and Z axes, the repeated positioning, the relative straight angle of each axis, the stability of the bed, the workpiece
