Raw material production process

Select tungsten carbide powder according to adjustment.after smashing,drying,and adding forming agent,drying again,then obtain the mixture by sifting.then press,sinter-HIP treatment,and we get the raw piece of tungsten carbide circular knife.we use automatic inclinable wet milling machine to make tungsten carbide power grain size have the best mixture state in the sinter-HIP treatment, we adopt the largest international 5th generation high vacuum sintering pressurized furnace promote quality assurance








Finishing process

grinding surface of knives,grinding outer cutting edge and inner hole of circular knife.we use wire-electrode cutting to ensure the precision process tp location hole make products 100%  fits machine.then mirror polishing blades surface and chamfering knife edge.









Inspection of appearance and dimensional accuracy.100% microscope examination of cutting edge
