主　　题：PCBN cutter Cutting temperature Bearing steel 

摘      要：A thermoelectric curve of GCr15 BN500 is acquired by rapid label way. The study on measuring the cutting temperature with PCBN cutter is done and the calculation formula is achieved. A series of experiments about cutting temperature are made for different hardness tempering bearing steel at the same time. The rule that cutting temperature increases with increasing of the cutting speed, feed, back engagement of the cutting edge is gained. It is known that the cutting temperature is highest under the condition that back engagement of the cutting edge a p≥2.5 mm and the machined material hardness equals to 50HRC.
