In the previous section, we explained the main methods of the transmission system of CNC lathes. In order to minimize power loss and improve transmission efficiency, transmission components were born in the entire transmission system. The transmission components of CNC lathes have made outstanding contributions in improving lathe speed, accuracy, and rigidity. Today, our CNC lathe manufacturer will explain the four major manifestations of the transmission components of CNC lathes.
1. Spindle: Due to the appearance of the spindle, the main transmission system of high-speed CNC machine tools has eliminated belt pulley transmission and gear transmission. The spindle of the machine tool is directly driven by an embedded motor, which shortens the length of the main transmission chain of the machine tool to zero, achieving zero transmission of the machine tool.
2. Linear motor: It is a transmission device that directly converts electrical energy into mechanical energy for linear motion without the need for an intermediate conversion mechanism. This can be seen as the rotating motor cutting radially and unfolding into a plane. Now, turntables, including some horizontal machining centers, also use direct motor drive.
3. Elastic coupling: This is relatively traditional. Elastic couplings use parallel or spiral groove systems to adapt to various deviations and correctly transmit torque. Flexible couplings usually have good performance and are more cost-effective. Among the many practical applications of stepper and servo systems, flexible couplings are products. Through the integrated design, the flexible coupling smoothly transmits torque.
4. Roller type cam mechanism: The cam separator is a mechanism that achieves intermittent motion, with high indexing accuracy, stable operation, large torque transmission, self-locking during positioning, compact structure, small volume, low noise, good high-speed performance, and long service life. It is significantly used for exchanging or exchanging with workbenches. From the above products, it can be seen that the current transmission system has good high-speed, high-precision, low friction, and small clearance.
The above are the four manifestations of the transmission pair of CNC lathes that our CNC lathe manufacturer has compiled and published for everyone. We hope that the above description can be helpful for everyone in understanding CNC lathes.
