PCBN Tool For Dry Cutting Process

PCBN tool is an ideal tool material for the dry cutting process

Due to economic and environmental reasons, dry cutting has become a key research topic in the field of mechanical manufacturing in recent years. Let's first look at the wet cutting process due to the use of cutting fluid problems: 1. Long-term exposure to the air or cutting heat caused by cutting fluid fog volatilization, easy to pollute the environment, harm the health of the operator. Cutting fluid sulfur, chlorine and other additives more harmful, affect the quality of the processing surface. 2. The use of cutting fluid affects the processing cost. According to statistics, cutting fluid accounts for 15% of the production cost, while tool cost only accounts for 3% ~ 4%. 3. Cutting fluid leakage, the overflow will pollute the environment, easy to occur safety, quality accidents. 4. The transmission, recovery, filtration and other devices of cutting fluid and their maintenance costs are relatively high, which increases the production cost.

Advantage of PCBN tool dry cutting process

As a result of the above reasons, dry cutting processing technology in the western industrial developed countries have a considerable application. Compared with wet cutting, our recommended dry cutting process can make full use of the cutting performance of the tool and greatly increase productivity. The mechanism is because the cutting speed is very high, the generated heat is concentrated in the front of the cutting tool so that the material near the cutting area reaches the red hot state, yield strength decreases, and thus achieve the effect of improving the cutting efficiency. The use of dry cutting technology is the premise of higher cutting temperature, the strength of the cutting material has decreased significantly, become free cutting, and the strength of the cutting tool material in the same state to have a better red hardness and thermal stability, but also have better wear resistance and adhesive resistance. Suitable for dry cutting process of cutting tool material is ceramic, metal, ceramic, coated carbide and materials and so on, but in terms of red hardness and thermal stability. PCBN material is most suitable for the dry cutting process of cutting tool material, and as a result of PCBN cutting tool material has the advantages of more suitable for high speed under the condition of dry cutting. Using PCBN cutting tool cutting grey cast iron of dry cutting and cutting wet contrast can be seen in both cases: PCBN in high speed dry cutting condition, specific humidity higher cutting tool life.
