4 Principles of Precision Parts CNC Machining

To ensure the precision parts quality, Henrong follows below 4 principles for CNC machining:

– Benchmark first: process benchmark surface first, parts in the machining process, appearance as a positioning benchmark should be processed first, in order to provide accurate benchmark for the following process as soon as possible.

– Divided processing stage: machined appearance with high quality requirements, generally can be divided into three stages of rough machining, semifinishing and finish machining. Mainly to ensure the processing quality, conducive to scientific application equipment, easy to arrange heat treatment process and easy to find blank defects.

– Plane first and hole second: for parts such as box, bracket and connecting rod and other parts, the plane should be processed before the hole. In this way, the hole can be machined by plane position, ensure the accuracy of plane and hole position, and it is convenient to process the holes in the plane.

– Finishing cut: main surface finishing cut, such as grinding, honing, precision grinding, roll finishing, etc., should be placed at the end of the process. The general principles of precision parts processing route, develop the precision parts processing process procedure, can be roughly divided into two links. First is draw up parts processing process route, and then determine the process size, equipment and process equipment, cutting specifications and hour norm for each process.
