      If we want to extend the service life of tools, we need to choose the types of metal working fluids reasonably and optimize the processing methods, especially for difficult to machine materials. High quality cutting fluids are needed for cutting hard materials, and the cost of this cutting fluid is also expensive. However, during the cutting process, difficult machining materials often cause adverse effects on the service life of tools. Therefore, choosing the right cutting fluid to prolong the service life and reduce the processing cost is very necessary. The direct cause of tool failure is the cutting force and heat, so no matter what kind of processing method is adopted, its fundamental purpose is to reduce the cutting part of the tool and the temperature of parts to be processed, to prevent the parts to be machined surface hardening and the tip temperature is too high, increase the heat dissipation area, cutting force control.

      Resolvent:

      1. Proper control of cutting force and cutting speed

      The proper control of cutting force and cutting speed is also one of the effective means to reduce the temperature of the processing area and prolong the service life of the cutting fluid. In the process of processing hard material, the cutting edge is generally used through fine grinding, and the cutting depth and cutting width should not be too large. The selection of cutting line speed should be considered according to different material types, parts structure and processing equipment. 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. Select a reasonable cutting method

      For difficult to process materials, the choice of different cutting methods on the cutting fluid damage is very different. No matter which cutting method is chosen, the principle is the same, which is to reduce the cutting force as much as possible and reduce the temperature of the cutting area. The approach can reduce the cycloid cutting area, the actual cutting angle of cutting fluid bag is smaller, 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, the effect on the corner obviously; the feed cutting method, with a smaller depth, larger feed effectively reduce the cutting force, the cutting heat is generated in the processing of small, low temperature processing area.

      3, ensure timely and effective cuttings

      In metal processing, there will usually be a lot of cutting heat generated on cutting chips. If we can control chip length and ensure timely and effective chip breaking, we can take part of cutting heat away from chips, so chip breaking is an effective way to control cutting temperature. When machining difficult to machine materials, in the rough machining process, under the premise that the machining system is rigid, we should try to make chip breaking in the whole process. At the same time, the cutting fluid which has good settlement performance is used to discharge the cutting debris, so that the cutting chips can not be rubbed with the surface of the workpiece. The general cutting fluid SCC730A of the chemical industry can be selected. SCC730A water-based environmental cutting fluid is made of special high performance additives, antirust additives and other additives. It is a high performance multi-purpose cutting / grinding fluid. When mixed with water, a stable transparent solution can be formed. This product has good settlement, lubricity, antirust, cooling and cleaning. It has strong ability to resist microbial decomposition, and can still maintain its stability under different water hardness. The service life is more than 5 times that of the ordinary emulsified oil.
