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.
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 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.
