Information

Lapping machine Manufacturers china refers to a grinding machine that grinds the surface of the workpiece with a grinding tool coated or embedded with abrasives. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in workpieces. So how much do you know about its principles? Let's have a simple understanding together!
Lapping machine Manufacturers china The variable speed control method, the grinding process has three stages, namely the initial stage, the formal stage and the end stage. In the beginning of the grinding process, the acceleration of artificially controlling the rotational speed of the abrasive tool increases from zero to fast. When the rotational speed of the abrasive tool rises to half of the official grinding speed, an inflection point appears in the acceleration change, and the speed of controlling the rotational speed of the abrasive tool increases. The acceleration decreases from the maximum value from fast to slow until the grinding wheel speed reaches the official grinding speed, and the acceleration of the grinding wheel speed drops to zero.
Using the feature of fixed abrasive grinding, according to the relative motion track density distribution between the workpiece and abrasives, the abrasive density distribution on the abrasives is reasonably designed, so that the wear of the abrasives during the grinding process does not affect the surface accuracy of the abrasives , thereby significantly improving the surface accuracy of the workpiece and avoiding the trouble of dressing the abrasive tool. In plane fixed abrasive grinding, the rotational motion of the abrasive tool is the main motion, and the motion of the workpiece is the auxiliary motion. In most cases, the workpiece is floating and pressed on the grinding tool, and its motion law is unknown. Therefore, it is necessary to analyze the force of the workpiece in order to obtain its force state and motion law. The workpiece is taken as the separation body of the whole grinding system, the differential equation of the workpiece force balance is established, and the motion law of the workpiece can be obtained by solving the equation.
The above is a brief introduction to the relevant principles and knowledge of Lapping machine Manufacturers china.
