1, engraving and milling machine gong steel must be more than 10,000 rpm, many friends with computer gongs have not used the engraving and milling machine, with the computer gong processing thinking to use the engraving and milling machine is wrong, for the computer gong to open thick must be strong must speed slow, the speed is too fast, easy to burn the tool, milling machine is also a reason, so the milling machine has set the fast and slow gear. This is because computer gongs and milling machines can only get more torque at low speeds. The electric spindle used in the engraving and milling machine must reach a high speed of about 10,000 rpm in order to output large torque, if the thinking of the computer gong is used to play the spindle speed to about 2,000 rpm when the engraving and milling machine is rough, it is easy to scrap the electric spindle.
2. The speed is too low, the sound of the electric spindle is heavy, the gong is hard to work during processing, sometimes the spindle cannot be rotated, and the inverter alarms the overload. In severe cases, it will lead to the scrapping of the motor spindle.
3. Oil should also be flushed during processing, no oil should be flushed when the computer gong is rough, but the engraving and milling machine should be flushed with oil, the spindle rotates at high speed, the temperature rises, and it is easy to lead to tool wear without oil.
