(1) manual operation mechanical polishing: is by cutting, material surface plastic deformation removed after polishing the convex and smooth surface polishing method, generally use oil, wool wheel, sandpaper, etc., is given priority to with manual operation, special parts such as rotary surface, can use auxiliary tools such as rotary table, high surface quality requirements can use the method of super fine research. Super precision grinding is the use of special grinding tool, in the grinding liquid containing the abrasive, pressed on the processed surface of the workpiece, for high-speed rotating motion.
(2) Use the plane grinder for the mold mirror polishing
Some conditions need to be met: the processing surface is pure plane (with a little radian), workpiece diameter or diagonal 470mm, thickness of 200mm; the plane grinder can be polished; simply, the plane polishing conditions. The advantages of such a polishing method are: fast polishing speed, high yield, suitable for mass production. Take polishing mold steel as an example, the specific method steps: it is a little complicated, the specific details can refer to the mold steel mirror polishing.
The mold steel mirror polishing process is usually divided into three steps: rough grinding, rough throwing and fine throwing. If the planness of the workpiece itself is better, the rough grinding step can be ski. The choice of the grinding fluid is very critical.
Through the thinning work of the iron plate, if the planness of the product is poor, it is necessary to grind out a certain size to reach a plane, which virtually increases the difficulty, so the selection of synthetic iron plate should consider several points, that is, the iron disk has higher hardness and better cutting force.
This process mainly through the white skin and guide the Angle process. There are three things to pay attention to in this process:
The first is the pressure weight, the pressure weight is too light, the mark of the iron plate can not be thrown away, the specific pressure weight depends on the hardness of the workpiece.
The second is that this product wants to guide the Angle, so you need to pad a soft skin under the white cloth, which helps to guide the Angle, but the soft skin can not be too soft, too soft, there is no cutting force. The third is the choice of liquid, many manufacturers provide the liquid quality is too general, can not achieve the effect in a short time, this process is also the top priority, polishing this process, then the successful steps of this product is also accelerated.
Although the requirement is not too difficult, but it is not easy to ignore. First of all, this process is easy to product small scratches, so the polishing skin, and the quality of the polishing fluid must be guaranteed, the second is the sanitary conditions, the staff must do a good job of maintenance work.
Mirror polishing not only increases the beauty of the workpiece, but also makes the injection molding mold has other advantages, such as making the plastic products easy to unmold, reduce the production of injection molding cycle. But mirror polishing is also to pay attention to skills, can not simply pursue fast, this will backfire, not only waste time, and can not achieve the effect they want. Some people in order to pursue speed, at the beginning of the * fine sandpaper, oilstone or grinding polishing paste, so polished out of the mold, the surface looks very bright, but from the side, you can see a lot of thick lines, such a mold to the customer, is sure to be returned.
