The primary function of cemented carbide bushing is always that the bushing is a type of component to protect the equipment. The use of bushing can easily effectively reduce the have on between punch or bearing as well as the equipment, and achieve some sort of guiding role. In the particular aspect of stamping expire, tungsten steel bush is widely used because of its wear-resistant, good finish and no need of frequent replacing, so as to attain higher utilization rate connected with equipment and personnel.

Inside the aspect of drawing, the hard alloy bushing is especially the drawing of some copper and stainless steel parts. Due to the high frequency people, it is easy to be able to heat up and create wear bushing, which makes the punching pin run, the size error belonging to the product and the appearance in the product bad.

With the increase of oil production along with the decrease of oil on the shallow surface, in order to ensure the use of oil, people gradually turned out to be deep wells and deviated wells, women and men difficulty of oil output is gradually increasing, therefore the parts of oil production requires good wear resistance, corrosion resistance or impact opposition.

As a wear-resistant a part of petroleum machinery well, cemented carbide bushing provides high hardness, good put on resistance and high finish. It has been trusted in modern society and meets the needs regarding daily use and exclusive performance. Some enterprises adopt spray welding technology to enhance the durability and assistance life of cemented carbide bushing.

The hardness of the spray welded hard alloy bushing can reach HRC60, and the wear resistance is much better, which can meet a use requirements of the petroleum devices industry. However, the spray welded hard alloy bushing is required to be turned to ensure that dimensional requirements and accuracy requirements in the drawings.

Common tool elements include carbide tool, ceramic device and CBN tool, but carbide tool may be excluded from the hardness of carbide bushing. Although ceramic tool is suitable for machining high solidity workpiece, it is only made for finishing process with little allowance. Therefore, the best choice tool material for machining your cemented carbide bushing will be the cubic boron nitride device.
