The tungsten carbide bush also known as tungsten steel bushing, is a kind of component that protects the equipment, using the bushing, can effectively reduce the wear between the punch or bearing and the equipment and achieve a guiding role. The tungsten carbide bushing is mainly applied for stamping, with the features of wear resistance and impact resistance.

Excellent Characteristics Of Tungsten Carbide Bush

The tungsten carbide bushing has a series of excellent performances with high hardness, good concentricity, good perpendicularity, high wear resistance, high toughness, heat resistance and corrosion resistance. It has greatly improved the service life of the mold and has reduced the cost of molding manufacturers.

1. Advanced molding techniques can be adapted to produce a variety of shapes for carbide bush.

2. Small deformation with high accuracy.

3. High chemical stability

4. High bending strength

The Machining Method Of Tungsten Carbide Bush

The tungsten carbide bushing adopts CNC precision angles, inner hole grinder, precision surface grinding machine, precision internal and external round grinder, centerless grinder. The inner hole is grinded many times and polished into a mirror. The most suitable tool material for machining carbide bushing is a PCBN cutting tool.

The spray welding technology is adopted sometimes to increase the durability and service life of cemented carbide bush, which can reach HRC60 with better wear resistance. But the carbide bushing after welding needs turning machining to ensure the requirements for size and accuracy of the drawings.

Wide Applications Of Tungsten Carbide Bush

In the industrial fields, the application of cemented carbide bushing is very wide. The tungsten carbide sleeve is related to the role and purpose of its application environment in practical applications. In the valve application, the bushing should be mounted in the stem cover trap to reduce the valve leakage, for sealing. In the bearing application, the carbide bushing is adapted to reduce the wear between the bearing and the shaft seat, avoiding the clearance increasing between the shaft and the hole.

The tungsten carbide bushing is mainly used in the fields of stamping and stretching. The widely used tungsten carbide as tool material, includes a turning tool, a milling cutter, a planer, a drill bit, a boring cutter, etc, for cutting cast iron, non-ferrous metals, plastic, chemical fiber, graphite, glass, stone and ordinary steel, which can also be used for cutting materials which are difficult for machining, such as heat resistant steel, stainless steel, high manganese steel, tool steel.

In terms of stamping dies, the tungsten carbide bush is widely used because of high wear resistance, good finishing and no needing frequent replacement, thereby reaching the higher usage rate of equipment and personnel.

The carbide bushing has excellent chemical stability, which is widely applied in the industries of petrochemicals, submersible oil pumps, slurry pumps, water pumps, centrifugal pumps. With the increase in oil production, the shallow surface of the oil is reduced, In order to ensure oil usage, people have gradually developed to extract from the large deep well, but the difficulty of mining gradually increases and the mining components have high requirements for wear resistance, corrosion resistance or impact resistance. The tungsten carbide bush used as the wear-resistant component in the oil machinery, has high hardness, excellent wear resistance and a high degree of surface finishing, satisfying the use requirements for a daily and special performance in the oil machinery industry.

Summary

Tungsten carbide bush is a type of protective component with wide industrial applications. It has a high performance with High hardness, superior wear resistance, high strength, high toughness, heat resistance and corrosion resistance.
