The role of drill sleeves
Drilling The main function of the sleeve is to control the position and size of the tool and guide the feeding direction of the tool to meet the technical requirements for processing holes with high geometric tolerances and drilling on inclined surfaces. When the fixture positioning accuracy of the parts processed on the equipment is not ideal, sometimes the offset of the spindle can be deliberately changed through the drill sleeve to meet the technical requirements for the position of the processed holes. This is an emergency method on the premise that adjusting the equipment is time-consuming. . In addition, the drill bushings on individual stations of the special machine line can also serve as error-proof verification of diameter tools. That is, the production line operator inserts the new tool into the drill bushing hole before replacing the drill bit or reamer tool to verify whether it can pass the diameter adjustment of the tool. The risk of out-of-tolerance is controlled.
Materials of drill bushings
Depending on the differences in the processing objects and the material of the tool, the drill bushings are generally made of carbide or alloy steel. The drill bushings of high-speed steel drill bits or reamer tools are generally made of alloy steel. Or carbide material, and the drill sleeve of carbide drill bit or reamer tool will choose carbide material. Judging from the material of the drill bushing, although the hardness has finally reached a high level, the drill bushing will still fail after being used for a long time or under unreasonable use.
Drill bushings are widely used in electronic appliances, toys, machinery, digital optical instruments, pneumatics, hydraulics and other fields
