Common tools and specifications for mold polishing   In the process of die manufacturing, the formed parts of the die often need to be polished. Mastering the polishing technology can improve the quality and service life of the mold, and then improve the product quality.   Die polishing method and working principle Generally, oilstone strips, wool wheels, sandpaper, etc. are used for mold polishing to make the material surface plastic deformation and remove the protruding

Polishing process of injection mold (1) Rough throwing The surface after finishing milling, EDM, grinding and other processes can be polished with a rotary surface polishing machine with a speed of 35 000 ～ 40 000 r/min. Then it is manual grinding of oilstone, and the strip oilstone is added with kerosene as lubricant or coolant. The order of use is 180 # → 240 # → 320 # → 400 # → 600 #

Factors Affecting the Surface Polishing of Die (1) Workpiece surface condition In the process of machining, the surface of materials will be damaged due to heat, internal stress or other factors. Improper cutting parameters will affect the polishing effect. The surface after EDM is more difficult to grind than the surface after mechanical processing or heat treatment. Therefore, EDM finishing shall be adopted before the end of EDM, otherwise the surface will form a hardened

Most of the materials used for mold accessories are mold steel materials with high hardness, which requires mold accessories processing equipment to have thermal stability and high reliability. Especially for complex cavities and multi-function composite dies, with the complexity of the part shape, it is necessary to improve the design and manufacturing level of the die to ensure the processing quality of die accessories. What are the aspects of mold processing quality? What factors should
