1. The basic composition of the carving machine: bed organization, spindle motor, transmission method, control system, drive, stepper/servo motor, guide rail, frequency converter, pump, vacuum 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 toughness of the data. From the metallurgical principle, we know that by quenching and normalizing the treatment, it can promote the precipitation of a part of the carbides at the time of the intermediate temperature immersion (aging), and together, it can eliminate some residual stress caused by rapid cooling, so it can be improved. The resilience and flexibility of the data. The effect of obvious tempering treatment is determined by the tempering temperature, the moment, ie the cooling rate and other factors.
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's Shangyin 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.
Weihong and DSP comparison:
a. Weihong is connected to a computer PC, can directly map on the computer, and then import the carving process, directly processing. The DSP must use a USB flash drive to connect the DSP controller, which is not convenient.
b. Weihong operating system is more stable, the DSP handle is simple, the U disk is checked to find the simple virus, the program will be damaged, and the problem is many.
c. Weihong's optimization is better, the path of carving is softer, and circulation is better than DSP.
d. DSP handle memory is only 128M, because the stored files are limited, so the need to continuously delete files.
e. Weihong's ex-factory price is about 3,500, and the factory price of DSP is about 2,500.
7. Guide rail: divided into cylindrical guide rail, rectangular linear guide rail (square rail), we use Taiwan Hiwin20mm, 25mm, 30mm square rail, square rail is good. Imported rectangular linear guide rail stability and accuracy can reach than domestic cylindrical guide rail 30 times!
8. Vacuum pump, the advertising machine has no pump, because the advertising machine is the countertop of the T-slot aluminum profile, and the carpenter machine has the vacuum pump. Since the carpenter machine is the adsorption table of PVC, our PVC adsorption table is a layer of 25mm thick. 15mm thick double-layer PVC board, so the table top is very thick and strong. The function of the vacuum pump is to generate suction, which sucks the workpiece and fixes it. The vacuum pump has 140 flow rate and 250 flow rate. The selection of the vacuum pump is selected according to the size of the machine channel. Generally, the vacuum pump of 1325, 140 flow rate is satisfied. The vacuum pump used by us is made in China, and the German Beck pump is optional.
9. Vacuum adsorption is to use a vacuum pump to inhale under the countertop, vacuum, firmly hold the plate, now most manufacturers do the 6-zone vacuum adsorption countertop, let's do 4 partitions, some people will ask, people 6 partitions Good, sucking strong, in fact, this is not the case, do 4 partitions or 6 partitions can be, plus a partition cost is only about 250 yuan, the primary reason is that 4 partitions are practical, because the more partitions, the smaller the area, take 6 partition examples If the guest takes a small plate, it just occupies a half partition, then just open the vacuum adsorption switch of the two partitions, but according to the 4 partition, open an area is enough, open one, close three.
