In the milling process, the traditional milling machine adopts manual feed and then adds mechanical tools, but the mechanical tools have high processing requirements, high cost and troublesome operation. So later, the electric tool feeder appeared, which was regulated by DC motor, but there were some shortcomings in the structure. One was that the gear was prone to problems, and the other was that the carbon brush was prone to problems. Now there is a maintenance-free feed device, which is driven by servo motor and combined with electromechanical to realize low-speed and high-torque cutting and high-speed and fast moving. Under the control of single chip microcomputer, the motor is maintenance-free, and has won the national invention patent. Mainly used in high-speed universal rocker milling machine, drilling and boring machine, small grinder and special machine tools.
The power feed device of milling machine adopts independent power supply mode to provide workbench feed power for milling machine and other equipment, instead of the traditional milling machine feed gear box system. This product is mainly used for the working movement of the milling machine workbench in the three coordinate directions of X, Y and Z, realizing the positive and negative conversion direction and stepless speed regulation, which can completely replace the traditional gearbox speed change mechanism and is a revolutionary innovation in the development of milling machine from integral to discrete unit. The power feeder of milling machine has the characteristics of low noise, large torque, high rotation speed, convenient installation, flexible operation and beautiful appearance, which meets the requirements of ergonomics. Installed on the machine tool, it provides stable power for the machine tool and greatly improves the work efficiency.
