2020 Hot High frequency porcelain grinding stone metal polishing grinding medium can improve the brightness of work

Point and Purpose:
1. High-frequency porcelain polishing stone is mainly used for all kinds of precision hardware and electronic parts.
2. This type of Opal is used for polishing and grinding the surface of softer products such as aluminum alloys, zinc alloys, copper, resins(plastics), etc.. Commonly used for furniture hardware(such as handlebars, locks, etc.) and box hardware(such as belt buckle, bag buckle, shoe buckle, etc..)

Operation and Use
1, type, shape, size and load of millstone: the processing parts and the grinding stone that meets the grinding purpose, the material nature, size and shape are placed in the container tank to a total volume of more than 95 %(processing parts and millstone mixture). When using a new abrasive, it is best to first grind the abrasive itself for half an hour to remove abrasive surface dirt and sharp edges. 2. The mixing ratio of grinder and processing parts should be determined according to the size of the processed parts, the nature of the open material, and the condition of grinder. Generally, the ratio of processed parts to grinder is about 1:1 -1 :3. For example, rough polishing and medium polishing, this ratio is smaller, and this ratio is larger when fine polishing. 3, the amount of water added water generally takes 3 to 5 % of the total volume of the drum container, 3 % is rough grinding, 5 % is polishing, if too much is added, it causes resonance phenomenon and affects the grinding effect, so it must be controlled. The amount of water added.
4. The amount of grinding agent added and durable time: According to the purpose of grinding and the nature of the material, an appropriate grinding agent should be selected. The amount of addition should be divided into two types, about 360g for heavy cutting, about 600g for polishing, and one hour for durability. standard, If the grinding time exceeds one hour, the abrasive agent should be replaced in the middle. In the process of replacing the abrasive agent and water, the previous abrasive agent and water should be discharged, the abrasive material and parts should be cleaned, and then the abrasive agent and water should be re-added.
Determination of Grinding Time: The choice of grinding time should be changed according to the condition of the processed parts. Usually, the best time is found on the basis of the process test, so as to determine the grinding schedule of a tomb. 6. Cleaning of processing parts: Before processing parts, parts must be deoiled and decontaminated. If not carried out, it will reduce the service life of the PU glue and the effect of grinding. Separation of parts from abrasive: After processing, the workpiece can be cleaned directly in a spiral container and the water valve can be opened at the same time. After cleaning, select the appropriate size of the separation screen, and then put on the separation joint plate, so that the parts and abrasives are automatically separated, and the other parts should be cleaned, dried and rust-proof treatment.
