Talking About PCD Inserts Price

PCD Inserts is a competitive business. there is the various price for same type PCD Inserts. price range is about 7 to 20 USD/pcs. for many resellers, they always get about 10 USD/PCS.because they don't want to buy bad quality products and also want to get more profits. Back to PCD Inserts price, why are there so many different prices? 1. The material is the key. for 7 to 12 USD/PCS, they are using Unknown brand PCD material. for carbide base, they are using recycle resources. as you know, manufacturer need processing for inserts' angle and CNC cutting for basement.there is the precision issue. For 16 to 20 USD/PCS, those manufacturers are using band PCD material. (Such as E6, DI, Mitsubishi and so on) If you want to know about PCD inserts price. then you should know "how to make PCD Inserts?" Of course! price is one of reference.

What Is Tool Life?

People have many different opinions for tool life definition. for us, tool life is the reference value that how many applications can be processed for one cutting tool. this is not just about the time. Then you might want to know what tool life can be affected by?  There are Cutting Heat, friction and cutting resistance. and those three fatal factors are increasing when you start increasing cutting speed.  Cutting Heat depends on cutting speed, depth of cut, shape and attrition rate of cutting tools. Inefficiently cutting, the chip will take off 80% or 90% cutting heat.  For cutting speed, In general, the wear rate will increase by 50% if you raise 20% cutting speed. raising 20% feed, wear rate will increase by 20%. Raising 50% depth of cut, wear rate will increase by 20%.  A coin Has two sides. In the correct range of parameters, if linear velocity increased, it can decrease plastic deformation and raise cutting heat which can reduce work hardening of the workpiece and lo
