Selection and determination of non-standard hardware parts processing methods


Selection and determination of non-standard hardware parts processing methods

The processing of non-standard hardware parts generally requires more suitable processing methods to be selected according to the processing material, part structure, etc.https://lasercutting-service.com Therefore, here we briefly explain the selection and determination of processing methods.

(1) Selection of non-standard hardware parts processing methods
The selection principle of non-standard hardware parts processing method is to ensure the processing accuracy and surface roughness of the processed surface. Since there are generally many processing methods to obtain the same level of accuracy and surface roughness, in actual selection, comprehensive consideration should be given to the shape, size and heat treatment requirements of non-standard parts. For example, boring, reaming, grinding and other processing methods for IT7 precision holes can meet the accuracy requirements, but the holes on the box are generally boring or reaming, rather than grinding. Generally, https://ptjcnc.com reaming should be selected for the box hole of small size, and boring should be selected when the hole is larger. It should also consider the requirements of productivity and economy, as well as the actual conditions of the factory’s production equipment.

(2) Principles for determining the processing plan of non-standard hardware parts
The processing of more precise surfaces on non-standard parts is often gradually achieved through rough machining, semi-finishing and finishing. It is not enough to select the corresponding processing method based on the quality requirements for the processing surface of these non-standard hardware parts, and the processing plan from the blank to the forming should be correct. https://numerical-control.com/When determining the processing plan of non-standard hardware parts, first, according to the requirements of the main surface accuracy and surface roughness, the processing methods needed to meet these requirements should be initially determined. For example, for holes with IT7 precision with a small aperture, when the final processing method is fine reaming, the finishing reaming usually requires drilling, reaming, and rough reaming.
