tungsten carbide bushings are mainly used for stamping die layer and drawing layer. Cemented carbide tools are commonly used as tool materials, such as lathe tools, turning tools, planers, twist drills, boring tools, etc., for drilling pig iron, rare metals, plastics, chemical fibers, high-purity graphite, laminated glass, marble and Generally stainless steel plates, tungsten carbide bushings can also be used for drilling materials that are difficult to produce and process such as heat-resistant steel, stainless steel, high manganese steel, and alloy steel. Nowadays, the cutting amount of the new-style carbide tool CNC blade is equivalent to hundreds of times that of alloy steel.
The key function of cemented carbide tool bushing depends on that bushing is a kind of component for maintenance of machinery and equipment. The application of bushings can reasonably reduce the damage between the punching needle or rolling bearing and the machinery and equipment, and achieve a guide. The efficacy of sex. At the level of hardware molds, tungsten carbide shaft sleeves are widely used due to wear resistance and good smoothness, and do not need to be replaced frequently, thereby achieving higher utilization of machinery and equipment and staff.
Carbide tool bushings are at the stretching level, mainly for some copper parts and stainless steel plate parts. Due to the high frequency of application, it is very easy to get hot and cause damage to the bushing, which will cause the punching needle to move. The specifications of the product Deviations, and poor appearance of the product.
With the increase in crude oil production, the crude oil in the shallow surface layer is reduced to ensure that the demand for crude oil is gradually developing towards large deep water wells and highly inclined wells. However, the difficulty coefficient of extracting crude oil is slowly increasing, so the crude oil extraction The parts are required to have excellent wear resistance, corrosion resistance or impact resistance.
