The main drive system of CNC machining center has high torsional rigidity and optimized torque. If a workpiece needs to be accurately positioned, the return speed of the planetary reducer must be very small.
Tool system is the core module of NC machining center. Every tool change requires shorter time and time. To reduce time, it requires the cooperation of precision planetary reducer and servo motor to quickly drive the tool magazine. The tool changer requires the tool to accurately locate the moving position. Therefore, the planetary reducer must accelerate in a very short time while maintaining a fixed low return clearance and can be realized under various load conditions.
In modular machine tools, the connection mode of the spindle and the grip of the fixture (spindle, adjusting sleeve, column, etc.) usually needs to be connected by keys, and there are many problems and shortcomings in the development, such as a large number of adjusting pieces in enterprises, which cannot ensure sufficient joint rigidity. The use of special-shaped joints instead of key joints can increase the joint strength by five times, reduce the cost of manufacturing technology and reduce the weight of the fixture. The use of profile connection makes tool replacement convenient, clamping reliable, and adjustment simple, which improves the efficiency of management and learning. Because there is no series of advantages of formed joints, they are mainly used for metal cutting machines, automobile gearboxes, tractors and other machines. In the combination of machine tool and flexible module information system, the continuous analysis of the application capacity range economy of profile joints has been effectively promoted and achieved good results.
The above is an introduction to the application requirements of CNC machine tools for precision planetary reducer.
