Current Workshop Unconventional Test Sep 09,2020
As we know,every CNC Machinery Parts products need to test and check before selling out.And they would be tested repeatly.Now we will say about the Current Workshop Unconventional Test for the CNC machining parts.
1: Detection of inner diameter
When the workpiece can not be directly measured with the inside micrometer, the following methods can be referred to for inspection.
  • For the workpiece with wall thickness less than 30, first measure the outer circle size of the workpiece, and then measure the wall thickness size with a sharp divider, that is, the inner hole size = the outer circle size -2* the wall thickness size. This method can be controlled within 0.005.,
  • Measure the size of the hole by means of the table. First measure the size of the workpiece's outer circle. Then measure the size of the outer circle and the wall thickness with the table.This method can also be controlled within 0.005.
  • Check the hole size with the plug gauge of corresponding size.
  • THE CNC lathe can first finish the inner hole, see the light of the outer circle, send the product for three times of inspection, and change the way of filling the knife.
2. Measurement of short interval difference outer circle:
  • Numerical control equipment can be measured by means of calibration table, while non-numerical control equipment can be measured by means of pad gauge directly using micrometer card.That is, the outer circle size of the segment difference = the size of the pad gauge - the size of the block gauge.
  • First, measure the size of the outer circle. The size of the marking section difference is equal to the size of the outer circle -2* the marking section difference.
  • The CNC lathe can first finish the inner hole, the outer circle to see the light, and the product to be inspected for three times

After measurement, rewrite the way of knife filling.

Visual quality requirements
  • The appearance of the parts should not rust. Solution: oil the parts in time to prevent rust after processing.
  • There should be no scratches on the appearance of the parts. Solutions: the bottom surface of the workpiece can be filled with paper in the clamping process, and the workpiece can be placed with plastic box in the handling process. The workpiece should not be superimposed as far as possible.
  • The sharp corners, adjacent edges and planes of the workpiece should not be damaged. Solution: pay attention to the handling and handling of the workpiece. The sharp corners parts should be wrapped with white tape.
