Grinding tools, durability comparable unground improve

Practice shows that, after careful grinding tools, unmilled comparable durability increased by 50 percent. Using a cooling lubricant can reduce the temperature of the cutting zone and reduce tool and workpiece, the friction between the tool and the chip, to improve the tool life is advantageous. Experiments show that, with the emulsion  cutting tools  the cutting zone temperature 50 ℃ ~ 100 ℃, with cutting oil can reduce the cutting zone temperature 40 ℃ ~ 60 ℃. Therefore, high-speed steel cutting tool under conditions of heavy load, the multi-use aqueous cooling lubricants, cutting load lighter and requires high precision and surface roughness  abrasive grinding  are much lower with lubricant oil, the tool and lubricating film formed between the workpiece surface, to reduce friction. Carbide good heat resistance, generally without coolant, but in general steel with high-temperature  Polycrystalline diamond  finishing materials, in order to improve the durability of the tool, to ensure accuracy and surface roughness of the workpiece can also be used extreme pressure cutting oil emulsion or cooling lubrication. In summary, our analysis clearly affect the tool life of these factors and the relationship between them, may be based on the specific circumstances of the workpiece material, selection of appropriate materials and cutting tool, select the appropriate tool geometry, quality assurance tool sharpening and cooling lubrication conditions, in order to protect the higher tool life.
