Jinhong Mold Co., Ltd. Chengdu increase mold parts machining accuracy and surface quality of the mold parts processing quality, including precision and surface quality: precision is the actual size of the machined surface of the part, the ideal geometry shape, position, and three drawings of geometrical parameters The degree of compliance; deviation from the actual value of the part geometry and the ideal geometry is called processing errors. Machining accuracy and machining error term evaluation of machined surfaces are geometric parameters. Measure with precision tolerance class, grade value is smaller, the higher the precision; processing errors expressed numerically, the greater the value, the greater the error. High precision, is a small processing errors, and vice versa; any actual parameters obtained by processing methods are not absolutely accurate, from the part of the functional perspective, as long as the processing error within the tolerances required parts diagram, it is considered to ensure that the processing accuracy. As the company's existing equipment is difficult to meet the individual mold punch and die processing needs, including equipment processing capacity and can achieve precision machining ,, such as lack of precision forming grinder, EDM, or large-scale processing equipment, you can use a single step Waixiejiagong approach. 1. To make the mold production levels of the enterprise to adapt to the needs of the market, it should be based on the appropriate level of product parts and the ability to mold processing requirements, update or add a special mold processing equipment, such as precision molding grinder, EDM and CNC Copying milling machine and so on. 2. Mold Co., Ltd. Chengdu Xin takeoff batch stamping and die according to the choice of structural processing methods.
