An effective way to extend tool life(一)

As component manufacturers continue to increase productivity, customers often make annual requests to reduce the price of finished parts, which poses a challenge to the profit margins of component manufacturers. For their own survival and development, parts manufacturers must spare no effort to reduce production costs, improve the way, including: to improve staff productivity, extend tool life, improve supplies management, reduce energy consumption. Auto parts manufacturer ABI Showatech (India) company's management team is committed to these improvements, found a tool life can be extended, improve the quality of parts, reduce manufacturing costs and effective way.

The initial breakthrough stems from the study of tapping and thread quality. One customer complained that tiny metal particles were attached to the threaded hole wall of the car parts. In order to solve this problem, the technician has tried various methods, such as increasing the coolant pressure from 3 bar (44 psi) to 10 bar (145 psi) during tapping, using a wear-resistant taps to increase the cutting fluid Of the lubrication performance, but unfortunately, these measures are not satisfactory results, it is difficult to satisfactory.

By microscopic examination of the tapered cutting edge, it was found that some fine particles were adhered thereto. The conclusion is that these metal particles come from the aluminum alloy workpiece material, although they are very small, but will still hinder the tap effectively cutting the thread. It has been shown that the idea of removing these metal particles by increasing the coolant pressure is not correct.
