The processing of tungsten steel bushing
is an indispensable accessory when the stamping die is working, and it is a replaceable die consumable. The tungsten steel bushing made of special mold steel can have various shapes according to the needs of production. Tungsten steel bushings are also different according to different materials, shapes and uses. They can be mainly divided into SKD, SKH, ASP tungsten steel, tooth extraction tungsten steel, hexagonal tungsten steel, special-shaped tungsten steel, high-speed steel tungsten steel, etc.
(1) The machining of tungsten steel bushings should ensure that the workpiece evenly contacts all surfaces of the grinding tool. In this way, the surface of the grinding tool can be uniformly loaded and worn, and the surface accuracy of the grinding tool itself can be maintained for a long time.
(2) The processing of tungsten steel bushings should ensure that the workpiece is uniformly ground, that is, the grinding amount of each point on the surface of the workpiece to be ground should be the same. This is essential to ensure the geometric accuracy and dimensional uniformity of the workpiece.
(3) The processing of tungsten steel bushings should make the movement trajectory change direction regularly and regularly to avoid premature repetition. In this way, the countless cutting streaks on the workpiece surface can be regularly staggered and offset each other, that is, the more grinding, the smoother, so as to achieve the purpose of improving the surface quality of the workpiece.
(4) The grinding process of the tungsten steel bushing should be based on different grinding process requirements, and the optimal movement speed should be selected specifically. When grinding slender and large-size workpieces, it is necessary to select low-speed grinding; when grinding small-size or low-precision workpieces, select high-speed or high-speed grinding to improve production efficiency.
