1. High processing efficiencyIn large-scale thread machining, it is very difficult to improve machining efficiency due to the low cutting speed limit of Cobalt containing tap and the reverse tool retraction after machining the threads.However, if we use a thread milling cutter, not only does it have...

(1) The matrix of Hard alloy tap should be rich in 79% WC, 15% TiC, and 6% Co. According to the above analysis, the content of WC, TiC, and Co is significantly low, especially the content of Co is almost close to that of YT30. Therefore, TOSG Hard alloy tap become brittle during cutting, and wear is...

At present, manual tapping still holds a certain position in mechanical processing. Due to the limitations of the location or part shape of some Screw thread tap holes in actual production, they are not suitable for machine tapping spiral pointed tap. Therefore, it is necessary to use spiral threads...

In the process of cutting plastic metals, the workpiece material is pushed by the front cutting surface of the gas tap, undergoes deformation, and is eventually torn off to form chips. There are three deformation zones in this process. The degree of deformation in the first deformation zone characte...

Wire thread tap are composed of a working part and a handle. The working part consists of a cutting part and a calibration part. There are several (usually three or four) chip grooves in the axial direction, which correspondingly form several blade edges (cutting edges) and front corners. The cuttin...
