  1. Properly control the cutting force and cutting speed
  Proper control of cutting force and cutting speed is also one of the effective means to reduce the temperature of machining area and prolong the service life of cutting fluid.In the processing of difficult to process materials, the general use of precision grinding tool edge, cutting depth and cutting width should not be too large.When choosing the cutting line speed, the factors such as different material type, structure and machining equipment should be considered.Generally, if the processing material is nickel-based alloy, the linear speed should be controlled at 20 to 50 meters per minute;The processing material is titanium alloy, the linear speed should be controlled at 30 to 110 meters per minute;Processing materials for PH stainless steel, linear speed should be controlled in the range of 50 to 120 meters per minute.
  2. Choose a reasonable cutting method
  For hard - machined materials, different cutting methods have different damage to cutting fluid.No matter which cutting method is chosen, the principle is the same, which is to reduce the cutting force and cutting zone temperature as much as possible.The cycloid cutting method can greatly reduce the cutting area, so that the actual cutting envelope Angle of the cutting fluid is small, so as to extend the cooling time of each tooth of the cutter and reduce the cutting temperature.The spiral interpolation method can make the cutting amount of each tooth relatively uniform, avoid cutting force concentrated on a few teeth and accelerate the wear, this effect is more obvious at the corner;The large feed cutting method is adopted to effectively reduce the cutting force with a smaller cutting depth and a larger feed, so that less cutting heat is generated in the processing and the temperature in the processing area is lower.
  3. Ensure timely and effective chip breaking
  In metal processing, there is generally a lot of cutting heat generated in the cutting chip, if you can control the chip length, ensure timely and effective chip breaking, you can make this part of the cutting heat is taken away by the chip, so chip breaking is an effective way to control the cutting temperature.In the processing of difficult to process materials, in the rough processing process, under the premise of the rigidity of the processing system, should try to make it in the whole process of processing chip break.At the same time use the cutting fluid with good settlement performance, the cutting chip settlement is discharged, do not let the cutting chip and the workpiece surface friction, and water mixing, can form a stable transparent solution.The product has good sedimentation, lubrication, rust resistance, cooling and cleaning properties.It has strong anti-microbial decomposition ability, and can maintain its stability under different water hardness conditions.
