The most common CNC processing Bakelite in China can be done by blowing air. Use tungsten steel knife or PCD knife. Do not use white steel knife to rotate too fast to 1-10 meters. Moreover, when processing, pay attention to chip removal or the chips will be piled on the workpiece, the large plate-shaped workpiece will be deformed due to unclean treatment, of course, the product will also be deformed after a period of time, mainly affected by the temperature and humidity.
Do not use coolant when processing electrical board with China CNC. If coolant is used in the processing, the chips cut by it are easier to block the water pump. If you want to have a better cooling effect and make sure that there is no smoke everywhere in the workshop, it is good to use air mist to cool, but remember not to use water. Add antirust cutting fluid to the water to protect the machine tool from rust. If you want to process products with high flatness, you must use vacuum sucker. Of course, poor quality bakelite, serious deformation. Poor color hair weight, odor when cutting, easy to layer not delicate.
Analysis on the technical problems of CNC processing electric board in China:
The most common way to process Bakelite is to blow. Tungsten steel knife or PCD knife are used. White steel knife is not allowed. Do not rotate too fast. Feed 1-10 meters, (mainly depends on the power of the spindle, the diameter of the cutter, and the cutting depth. Generally, 3-4 meters is suitable. ）In addition, when processing, pay attention to chip removal, otherwise the chip will pile on the workpiece, the large plate-shaped workpiece will be deformed, of course, the product will be deformed after a period of time, mainly affected by temperature and humidity.
When using CNC computer gong to process electrical board, do not use coolant. If coolant is used in the process, the chips cut by it will be broken and water pump will be blocked easily. If you want to have a better cooling effect and make sure that there is no smoke everywhere in the workshop, it is good to use air mist to cool, but remember not to use water. Add antirust cutting fluid to the water to protect the machine tool from rust.
If you want to process products with high flatness, you must use vacuum sucker. Of course, poor quality bakelite, serious deformation. Poor color and heavy hair, stink when cutting, easy to layer, not delicate. This requires that when purchasing, we must choose manufacturers with better quality to purchase electrical boards.
