In the process of fine hardware processing, the application of machining process will produce extrusion pressure and friction two categories of main force, in order to make the external force on the precision of fine parts and components to effectively reduce the impact, you need to control the extrusion pressure and friction produced by the impact.
On the one hand, before the development of fine machining work, strict inspection of the processing equipment, if the fixed parts of the equipment position is tight, the need to take timely adjustment measures, so that the equipment on the fine hardware processing parts produced by the force of the role of the effective reduction. On the other hand, due to the existence of fine machining equipment surface friction is difficult to avoid, such as based on the production of parts during the production of fine parts and machine tools to occur in the case of mutual contact, there will be the corresponding friction formation. When the production work continues, the friction will increase, therefore, it is necessary to carry out daily inspection of the equipment process summary time, grinding its surface, so that the parts and equipment contact friction generated by the effective mitigation, and then make the precision of the fine hardware machining parts to be effectively improved.
In order to make the fine machining process of parts processing accuracy is effectively controlled, it is necessary to apply the machining process to the temperature of the process to be reasonable control. Due to the fine hardware processing equipment in the process of operation, easily affected by the temperature, whether the temperature is high or low, will have a certain impact on the normal and reliable operation of the equipment. Based on the actual processing period, if the temperature is high due to the running speed, it is necessary to use cold water cooling method to deal with it. For example: in the grinding process of fine parts, in the machine tool on the high-speed rotation of the grinding wheel and the parts will produce mutual friction, and thus generate a lot of heat. When the temperature is high, it will lead to deformation of the parts in contact with the grinding wheel, it is necessary to take cold water cooling method. In short, reasonable control of machining process application process temperature is very critical.
