Cemented Carbide Twist Drills Deep Hole Machining

Results: in the past is the first long cemented carbide with the HSS twist drill out of the hole, and then hollow drilling process twice, and finally finishing reamers. Now use a front-end for the whole of cemented carbide twist drills, only processing once last reamer finishing.

Cemented Carbide Twist Drill Grinding

Results: HSS drill processing, processed out of the aperture size tolerance, reached after the switch to cemented carbide twist drills prefabricated hole reamer machining requirements.

Summary: during the processing of this material, if not cemented carbide twist drills chisel edge processing to a certain extent, the life of the cemented carbide twist drills will be halved, it is necessary to mechanical cemented carbide twist drills type grinding.
