The Kent surface grinder manufacturer tells you that the surface grinder is a commonly used machine tool for machining. There are higher requirements for smoothness of motion, commutation accuracy, and commutation frequency. At present, surface grinders are developing towards large-scale and high-speed development, and the reciprocating speed of the worktable of some surface grinders has reached 40m/min. The Kent surface grinder manufacturer tells you that the large-scale high-speed surface grinder has a large inertia of motion. When it changes direction, it will cause the back pressure to rise sharply, which will cause the reverse impact, which will have a catastrophic impact on the machine tool, so the direction change The stability problem has become an important factor restricting the improvement of the working speed and machining accuracy of the grinder.

The Kent surface grinder manufacturer tells you that the commutation method and commutation control parameters in the system have a decisive effect on the commutation impact. The surface grinder adopts hydraulic transmission. The design of a new hydraulic reversing system is imminent. The following discusses the reversing impact of the grinder from the perspective of commutation methods and control strategies.
Mechanism of commutation shock
The Kent surface grinder manufacturer tells you that because of its hydraulic system, when the hydraulic drive surface grinder changes direction. The valve port of the reversing valve is instantly closed, and the oil circuit is suddenly disconnected, so that the oil in the oil return cavity cannot be drained.
The manufacturer of Kent surface grinder tells you that the larger m and v are, it can be seen. The greater the kinetic energy, the greater the commutation impact. The Kent surface grinder manufacturer tells you that for a surface grinder with large inertia and high speed operation, the commutation impact is huge, which not only affects the machining accuracy of the machine tool, but also hinders the normal operation and service life.
The Kent surface grinder manufacturer tells you that people want machine tools to achieve ideal commutation. The so-called ideal commutation means, usually. Under any working conditions, the speed of the machine tool can be smoothly reduced according to an ideal curve without sudden change. The speed is just reduced to zero at the moment the valve is closed, that is, all the kinetic energy is converted into heat energy and is consumed.
