Secondary way of driving the main drive of CNC milling machine

Characteristics of steel ball screw: 1) Compared with the sliding screw pair, the driving energy moment is 1/3 because there are many steel balls between the screw shaft and the screw nut of the ball screw pair. High frequency of activity. Compared with the overcoming sliding screw pair, the driving energy moment reaches 1/3 times, that is, the energy required to reach the consequences of different activities is 1/3 of the use of the bone screw pair. Very helpful in power saving range. 2) High-precision guarantee The steel ball screw pair is connected and consumed by the highest altitude machinery and facilities in the society created by Oman, especially the scope of the workshop conditions that are being researched, dismantled, and reviewed in various ages. Strict grasp, because the perfect quality management system ensures sufficient precision. 3) Micro-feed can be used for steel ball screw pair because of the use of steel ball movement, because the moment of momentum is extremely small, there is no such phenomenon as gliding activity, which can ensure the accurate and accurate micro-feed. 4) The backlash-free, rigid high-ball screw pair can be preloaded, because the preload can make the axial clearance reach a negative value, and then lose the high rigidity. (In practice, it is used for machine installation, etc., because the repulsive force of the steel ball can strengthen the rigidity of the silk mother part). The steel ball screw vice must prevent deterioration, and can adopt self-locking generators, back wheels and other forms to prevent deterioration.

There are four main ways to drive the main drive of the CNC milling machine. The main drive with variable-speed rollers is fragmented, and the two-speed transmission is completed through the use of double sliding rollers. Because the ancient numerical control milling machine used the electric effect of stepless price adjustment, because the stepless speed change can be completed after the gear wheel speed change, the scope of price adjustment was expanded. In addition, the input torque can be extended through the down-conversion transmission, which satisfies the request for input torque characteristics at low speeds of the main optical axis. Most of the displacements of the sliding rollers are completed by using hydraulic cylinders and forks, or by indirectly driving the rollers by the hydraulic cylinders. Large and small CNC milling machines often adopt this method. The main drive with fixed-ratio transmission is fragmented and the main optical axis electrical effect is transmitted to the main optical axis through the fixed-ratio transmission. At present, the fixed ratio transmission uses more belts (synchronous toothed belts and triangular belts), and some also use cone rollers. The main optical axis, which is used for high-speed and low-torque features, can adjust the price of the electrical effect itself to meet the requirements, and has a bumpy transmission, low noise, easy construction, and convenient adjustment of the device. This kind of transmission is mainly used on a CNC milling machine that has a high speed and a large speed range.
