How to make the CNC Machining processes ?

  When you get a workpiece, the technican will list the processing steps when he makes the process card. Do you know what the order of precision parts is?

  For the processing industry, the order is very important, it is related to the quality of the product. If there is a wrong order, it is easy to cause a great loss, serious words to start over, a little serious, is these products scrapped, precision parts processing is one of them, so what is the order of it?

  One, the precision parts processing order arrangement should be based on the parts of the structure and blank condition, as well as the need for positioning clamping to consider, the focus is the workpiece's rigidity is not destroyed.

  (1) The processing of the previous procedure should not affect the positioning and clamping of the next procedure, and the processing of general precision parts interspersed should also be considered comprehensively.

  (2) Advanced in-line inner cavity processing sequence, followed by contour processing.

  (3) In the same positioning, clamping way or the same knife processing process is the best connection, to reduce the number of repeated positioning, the number of knife changes and moving the press plate times.

  (4) In the same installation of multiple processes, should be arranged first to the workpiece rigid damage of the process.

  Two, the tool concentration is divided into procedures according to the use of the tool, with the same tool machining parts can be completed on all parts.Use the second knife and the third to do whatever else they can.This can reduce the knife change times, compress the space time, reduce the unnecessary positioning error.

  Three, in order to process the parts of a lot of processing content, according to its structural characteristics will be divided into several parts, such as the shape, shape, surface or plane.

  Generally, the plane and positioning surface are processed first, and the hole is processed later.

  The simple geometry is processed first, and then the complex geometry is processed.

  The parts with low precision are machined first, and the parts with high precision are machined again.
