First, the bed and the gantry. The bed is now mostly steel structure, and the gantry is divided into two structures: aluminum and square steel. The structure and size of the bed and gantry directly determine the weight of the machine. To the extent that the weight is heavier, the better, because the weight is heavy, it represents the stability, directly affects the processing accuracy!
Second, the spindle and power. The main shaft is divided into two types: water cooling and air cooling. Service life air cooling is longer than water cooling, but the cost is high. Because the water-cooled spindles are generally made in China, the domestic technology of air-cooled spindles is not very mature. Foreign brands: Italy HSD, GC (Columbus), TEKNOMOTOZ (Gree), and other brands are more mature, and the brand reputation is better. The spindle power is suitable for mass production and re-cutting.
Third, the adsorption device. Batch production is more effective than the T-slot table (platen pressure) to improve the calibration rate and save the clamping time.
Fourth, the vacuum device. Processing of wood materials, dust is particularly serious, if it is too dirty, it is not good for the service life of the machine or the staff, it is recommended to use.
Fifth, the control method. It is divided into DSP handle control and computer connection. The handle control makes the operation more convenient during operation, but the online life is shorter than the shortcoming life. Only the movement coordinate of the display device does not display the machining track, and the computer can display the simulation processing track and motion coordinates.
Sixth, the transmission system. Woodworking machines are mostly rack + linear guide transmission. The rack ensures the speed of the equipment (empty path and machining speed), and the linear guide (square rail) has good linearity, which ensures the machining accuracy. The position of the drive system in the entire machine tool is particularly important and should determine the performance of the machine.
Seven, maintenance and maintenance. Sub-automatic lubrication system (software control) and semi-automatic lubrication system (manual control)
Eight, the drive system. The stepping system and the servo system are step-by-step systems with open-loop control, low torque and poor precision. Servo system (closed loop control, high torque and high precision)
Nine, working voltage. Under normal conditions, the rated voltage is 380v/50HZ, and the special case can be changed to 220V / 50HZ.
Ten, software. Control software and programming software, control software such as: Weihong, Taiwan Baoyuan, the new generation is more mature. Programming software: domestic Wentai, fine carving, etc.; foreign: French TYPE3, UK: Artcam, etc.
XI, after selecting the appropriate configuration, it is time to compare the price, that is, the price
12. After-sales service. Good after-sales service is especially important, from the brand, the region, whether the manufacturer has the strength of production training to investigate!
