  1 、 control the cutting force and cutting speed properly
  Controlling the cutting force and cutting speed of cutting tools properly is also one of the effective means to reduce the temperature in the working area and prolong the service life of cutting fluid. When machining difficult materials, cutting edges and cutting widths should not be too large. The choice of cutting line speed, according to different types of materials, parts, structures and processing equipment and other factors to consider. In general, if the material is nickel base alloy, the line speed should be controlled at 20 to 50 meters per minute; processing material for titanium alloy, the line speed should be controlled at 30 per minute to 110 meters; the processing material is PH stainless steel, wire speed should be controlled in the range of 50 to 120 meters per minute in.

  2. Choose reasonable cutting methods
  For difficult to machine materials, the choice of different cutting methods for cutting fluid damage is very different. No matter which cutting method is selected, the principle is the same, that is, as much as possible to reduce the cutting force and reduce the temperature of the cutting zone. The method can greatly reduce the cycloid cut cutting area, making the actual cutting bag cutting fluid to reach low angle, thereby prolonging cooling time every tooth cutter, the cutting temperature; the spiral interpolation method can make each tooth cutting quantity is relatively uniform, avoid cutting force concentrated in a few teeth and accelerated wear, especially the effect of it is obvious in the corner; and the feed cutting method, with a smaller depth, larger feed effectively reduce the cutting force, the cutting heat generated less processing in the processing area at low temperature.
  3, to ensure timely and effective chip breaking
  In metal processing, generally there will be a lot of cutting heat generated at the cutting chip, if able to control chip length, ensuring timely and effective chip breaking can make this part of the cutting heat is chipping away, so the chip breaking is an effective way to control the cutting temperature. In the process of machining difficult materials, especially in the rough working process, under the premise of the rigidity of the processing system, the chip will be broken as far as possible during the whole process. At the same time, the use of good performance of the cutting fluid, the removal of debris removal, do not let the workpiece and the workpiece surface friction. Optional chemical universal cutting fluid SCC730A can be used. SCC730A water environmental friendly cutting fluid is made of special high performance additives, rust inhibitors and other additives. It is a high performance multipurpose cutting / grinding fluid. When mixed with water, a stable transparent solution is formed. This product has good sedimentation, lubricity, rust resistance, cooling and cleaning. It has a strong ability of anti microbial degradation and can maintain its stability under different water hardness conditions. The service life is more than 5 times of that of the common emulsified oil.
