1. The basic composition of the engraving machine: bed organization, spindle motor, transmission method, control system, drive, stepper/servo motor, guide rail, frequency converter, pump, vacuuming equipment, etc. The drive drives the motor, and the inverter converts the spindle
2. The bed is generally made of steel, and our beds are tempered to reduce internal stress. The tempering treatment refers to a treatment in which the steel material which has been quenched or normalized is cooled at a certain rate after being immersed in a temperature lower than the critical temperature to add the resistance of the data. From the principle of metallurgy, we know that by quenching and normalizing the treatment, it can promote the separation of a part of the carbides at the moment of returning to the intermediate temperature immersion (aging), and at the same time, it can eliminate some residual stress caused by rapid cooling. Improve the patience and flexibility of the data. Obviously, the effect of tempering is determined by the tempering temperature, the moment, the cooling rate, etc.
3. The main shaft is divided into air-cooled and water-cooled, generally made of domestic water-cooled, Italian air-cooled. Commonly used Italian brands are HSD, Columbus, and Ida.
4. Motor. The motor and the driver are integrated. Our stepping motor is China's Chuangwei, and the brand is not bad. The servo motor is equipped with Taiwan Delta. The matching is Yaskawa, Japan, and the servo motor is 750W.
5. The transmission method includes rack drive and screw drive. The rack speed is fast and the precision is low. It is generally used on the carpenter machine. The relative speed of the screw is slow and the precision is high. It is generally used on the advertising machine. Most manufacturers practice XY shaft racks and Z-axis ball screws. Many manufacturers say that imported screw rods are very expensive to import, so many manufacturers are fraudulent, but they can choose the ball screw of Taiwan Silver Hiwin.
6. There are many control systems. We generally use Shanghai Weihong (NC), Beijing Reiz Tianhong DSP controller, Taiwan Baoyuan M520i (LNC), the most frequently used is NC.
