Junqiang machinery tells you how to prolong the tool life?
In order to prolong the service life of the cutting tool, it is necessary to choose the type of metalworking fluid reasonably and optimize the processing method, especially for the difficult to machine materials. High quality cutting fluid is needed when cutting difficult materials, and the cost of this kind of cutting fluid is also relatively expensive. However, in the process of cutting, difficult to machine materials often have an adverse impact on the tool life, so it is necessary to choose the appropriate cutting fluid, effectively extend the tool life and reduce the processing cost. The direct cause of tool damage is cutting force and cutting heat. Therefore, no matter what kind of processing method is adopted, the fundamental purpose is to reduce the temperature of the tool tip and the processed area of the parts to a large extent, prevent the surface hardening of the machined parts and the temperature of the tool tip from being too high, increase the heat dissipation area, and control the cutting force. Resolvent: 1. Proper control of 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. When machining difficult to machine materials, generally use the tool edge after fine grinding, cutting depth and cutting width should not be too large. The selection of cutting line speed should be based on different material types, parts structure and processing equipment. In general, if the processing material is nickel base alloy, the linear speed should be controlled at 20 to 50 meters per minute; The processing material is titanium alloy, and the linear speed should be controlled at 30 to 110 meters per minute; The processing material is pH stainless steel, and the linear speed should be controlled in the range of 50 to 120 meters per minute. 2. Choosing reasonable cutting method For difficult to machine materials, the damage of cutting fluid varies greatly with different cutting methods. No matter which cutting method is chosen, the principle is the same, that is to reduce the cutting force and the cutting zone temperature as much as possible. The cycloid cutting method can greatly reduce the cutting area and make the actual cutting envelope angle of the cutting fluid smaller, so as to extend the heat dissipation time of each tooth and reduce the cutting temperature; The spiral interpolation method can make the cutting amount of each tooth relatively uniform, avoid the cutting force concentrated on a few teeth and accelerate the wear, and the effect is obvious at the corner; However, the large feed cutting mode can effectively reduce the cutting force with smaller cutting depth and larger feed, resulting in smaller cutting heat and lower temperature in the processing area. 3. Ensure timely and effective chip breaking In metal processing, a large amount of cutting heat is generated on the cutting chip. If the chip length can be controlled to ensure timely and effective chip breaking, this part of cutting heat can be taken away by the chip. Therefore, chip breaking is an effective way to control the cutting temperature. When machining difficult materials, especially in the rough machining process, under the premise that the rigidity of the machining system allows, chip breaking should be produced in the whole machining process as far as possible. At the same time, use the cutting fluid with good sedimentation performance to discharge the cutting chip sedimentation, and do not let the cutting chip rub with the surface of the workpiece. General cutting fluid scc730a can be selected. Scc730a water-based environmental protection cutting fluid is compounded with antirust agent and other additives. It is a high-performance multi-purpose cutting fluid. When mixed with water, a stable transparent solution can be formed. This product has good sedimentation, antirust, cooling and cleaning properties. It has strong anti microbial decomposition ability and can maintain its stability under different water hardness conditions. Its service life is more than 5 times of that of ordinary emulsified oil.
