螺纹加工用的什么切削液(国外英文资料) Thread cutting tool materials and cutting into wedges, blade on three sides surrounded by cutting materials, cutting torque, chip removal difficult, cannot timely by the chip away heat, tool wear and tear, congestion cutting piece and prone to vibration. Especially when threading and tapping screw thread cutting condition is more strict, can appear sometimes collapse and the blade is broken tap, requires cutting fluid also have lower friction coefficient and high extreme pressure resistance, in order to reduce the friction of tool and to extend the service life of cutting tools. Compound cutting fluid containing both oily and extreme pressure agents should be used. Besides, the permeability of cutting fluid is very important when tapping, the cutting fluid can penetrate the blade in time, and it has a great effect on the durability of the tap. The permeability of the cutting fluid is related to viscosity, the viscosity is better, and a small amount of diesel oil or kerosene can be added to improve the effect of penetration. In some cases, such as blind tapping, the cutting fluid can be difficult to enter into the hole, but it is better to use the more viscous and strong cutting fluid. Here are a few tapping screw thread with cutting fluid formula (mass fraction) : 1) curing fatty oil, chlorinated paraffin, 10% and 10%, fat 8%, L - AN15 total loss 72% oil, steel, alloy steel tapping screw thread shall apply. 2) jq-2 pressure lubricant 20%, jq-1 precision cutting lubricant 10%, l-an15 total loss system oil 70%, suitable for steel and alloy steel tapping. 3) jq-2 pressure lubricant 15%, diesel oil 20%, l-an15 complete lossy system oil 65%, suitable for aluminum and aluminum alloy tapping. 4) jq-2 pressure lubricant 30%, chlorinated paraffin 10%, fat oil 10%, l-an32 total loss system oil 50%, suitable for stainless steel and blind tapping. 5) high pressure emulsified oil 20% + water 80%, suitable for steel standard thread processing.
