Professional China Drill Chuck - High quality drill bits for different drilling processing – FOREST Detail:

Product Description

In mechanical processing, according to the different structure and technical requirements of the hole, different processing methods can be used. These methods can be summarized into two categories: one is to process the hole on the solid workpiece, that is, to process the hole from the entity; The other is semi-finishing and finishing of existing holes. Non-matching holes are generally drilled directly on the solid workpiece by drilling; for matching holes, it is necessary to drill on the basis of the accuracy and surface quality requirements of the processed hole, using reaming, boring, and grinding. Fine processing methods such as cutting for further processing. Reaming and boring are typical cutting methods for finishing existing holes. To realize the precision machining of holes, the main machining method is grinding. When the surface quality of the hole is required to be very high, it is necessary to use fine boring, grinding, honing, rolling and other surface finishing methods; the processing of non-round holes requires the use of slotting, broaching and special processing methods.
