Best Tub grinder on sales introduces the principle of grinder
Grinding machine refers to a grinding machine that uses a grinding tool coated or embedded with abrasives to grind the surface of a workpiece. It is mainly used to grind high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other profiles in workpieces. So how much do you know about its principle? Follow the editor of Best Tub grinder on sales to have a simple understanding!
Grinding machine variable speed control method, the grinding process has three stages, namely, the beginning stage, the formal stage and the end stage. The grinding tool rotates at an increasing speed in the initial stage, the grinding tool rotates at a constant speed in the formal stage, and the grinding tool rotates at a reduced speed in the final stage. It is characterized in that: At the beginning of the grinding process, the acceleration that artificially controls the speed of the grinding tool increases from zero to fast. When the speed of the grinding tool rises to half of the formal grinding speed, an inflection point appears in the acceleration change, and the acceleration that controls the speed of the grinding tool is increased by The maximum value decreases from fast to slow, until the grinding tool rotation speed reaches the official grinding speed, and the acceleration of the grinding tool rotation speed drops to zero.
Using the characteristics of fixed abrasive grinding, according to the relative motion track density distribution between the workpiece and the abrasive tools, reasonably design the abrasive density distribution on the abrasive tool, so that the wear of the abrasive tool during the grinding process does not affect the surface accuracy of the abrasive tool. , Thus significantly improve the surface accuracy of the workpiece, and avoid the trouble of dressing abrasive tools. In plane fixed abrasive grinding, the rotational movement of the abrasive tool is the main movement, and the movement of the workpiece is the auxiliary movement. In most cases, the workpiece is floating on the grinding tool, and its motion law is unknown. Therefore, it is necessary to analyze the force of the workpiece in order to find the force state and the law of motion. Taking the workpiece as a separate body of the entire grinding system, the differential equation of the workpiece force balance is established, and the law of movement of the workpiece can be obtained by solving the equation.
The above is the editor of Best Tub grinder on sales: a brief introduction to the principle and related knowledge of the grinder.
