Precision stamping parts processing requirements

1. Parallelism requirements 　　 The so-called parallelism requirements for precision stamping parts processing are the tolerance requirements around the precision stamping parts, for example, rectangular workpieces, and machining requires the thickness of the four corners of the workpiece to reach a certain tolerance range. If the thickness of the four sides measured does not meet the tolerance requirements, the parallelism requirements will not be met. This requires readjusting the workpiece. The problem may occur in the suction cup of the grinder. The suction cup is overused,

Computer gongs are worn out, which leads to errors in parallelism; it may also be that the grinding wheel is not repaired well, or the grinding wheel is cracked or chipped. At this time, the grinding wheel must be re-grinded; or the suction cups are not cleaned, which must be re- Clean the suction cup and carefully clean it; it may also be that the workpiece has not been trimmed and burrs have appeared.　　Second, verticality requirement 　　 And the verticality requirement is to require the side and ground of the workpiece to meet the tolerance requirements. The best thing to understand is the legitimate body. From the perspective of the number axis, the machining of mechanical parts is divided into three sides, XYZ, and XZ and YZ are generally required to meet the tolerance requirements. The error is also roughly the same as the parallelism requirement. Generally, it can be handled according to the parallelism requirements.　　3. Other requirements　　 In addition to the above two aspects, precision stamping parts also have processing requirements such as finish and mirror effect, which often require attention.
