The double-head chamfering machine is controlled by a stepless speed regulation system, which can easily adjust the grinding speed suitable for grinding various components. The electro-pneumatic proportional valve closed-loop reaction grinder is used for pressure control, which can independently adjust the pressure equipment. The upper plate is provided with a slow-down function, which is useful for preventing the breakage of thin and brittle workpieces. After a time relay and a grinding counter, the grinding time and the number of grinding cycles can be accurately set and controlled according to the processing requirements. The pressure form can be adjusted during the operation. When the grinding setting time or the lap speed is reached, it will automatically stop the alarm and prompt to complete the semi-active operation. This feature of using fixed abrasive grinding, according to the density distribution of the relative motion trajectory between the workpiece and the abrasive, rationally plan the abrasive density distribution on the abrasive, so that the wear of the abrasive during the grinding process does not affect the accuracy of the abrasive surface. , So as to significantly improve the surface accuracy of the workpiece, and prevent the trouble of dressing the grinding tool.

The main body of the double-head chamfering machine is driven by a speed-regulating motor, equipped with a high-power deceleration system, with soft start and soft stop, and smooth operation. After the upper and lower grinding discs, the sun wheel of the grinding machine, and the star wheel form a grinding movement in four directions and speeds in harmony with each other, they reach the upper and lower surfaces for efficient operation of grinding together. The lower grinding disc can be raised and lowered to facilitate the loading and unloading of workpieces. Pneumatic sun gear direction changing equipment, accurately control the grinding precision and speed of the workpiece on both sides. Equipped with a correction wheel for correcting the parallel errors of the upper and lower grinding discs.

The grinding basket grinder inherits the characteristics of the basket grinder. The two processes of loose grinding are completed on one machine and one process. Together, it can also be used as a loose machine (when the loose disk is in the operating position and the grinding basket is not lowered) . Regarding the materials that need to be ground, it can complete the function of first dispersing and then grinding (when the grinding basket is lowered to the operating position, the materials can be efficiently ground).

Double-head chamfering machine variable speed control method, there are three stages in the grinding process, namely the beginning stage, the official stage and the end stage. The characteristic is that at the beginning of the grinding process, the acceleration of the artificial control of the abrasive speed increases from zero to slow. When the abrasive speed rises to half of the official grinding speed, there is an inflection point in the acceleration change, which controls the abrasive speed The acceleration of A is reduced from a large value from fast to slow until the grinding tool speed reaches the official grinding speed, and the acceleration of the grinding tool speed drops to zero.

In plane fixed abrasive grinding, the rotary motion of the grinding tool is the main motion, and the motion of the workpiece is the auxiliary motion. In most cases, the workpiece is floating pressed against the grinding tool, and its movement rule is unknown. Therefore, it is necessary to analyze the force of the workpiece to find its force state and motion rules. Taking the workpiece as a separate body of the entire grinding system, the differential equation of the force balance of the workpiece is established, and the motion rule of the workpiece can be obtained by solving the equation.
