Track Analysis And Research Of Ceramic Plane Grinding Machine
Precision plane grinding and polishing technology with abrasives or abrasives occupies a pivotal position in the field of precision processing and ultra-precision processing. It has been widely used and has become a metal line ruler, gauge block working face, mechanical seal ring, motor parts, hydraulic and pneumatic control parts, single crystal silicon, and laser record manufacturing. The key technology of precise processing of parts such as the mould of VCD.
The grinding method of ceramic plane grinder is a widely used grinding method in China. The grinding of the blade surface is usually carried out on a ceramic surface grinder. The grinding quality and production efficiency of blade plane, the uniformity of grinding disc wear and the degree of isolation disc wear are difficult to be controlled by the operator at will, but they are closely related to the grinding motion and trajectory of the grinding machine, and are closely related to the rational selection of grinding motion parameters.
The trajectory curve of planar polishing directly affects the quality and efficiency of polishing. It is a basic problem to understand the mechanism of polishing process. The trajectory curve of polishing process can be divided into two categories: the trajectory of a certain point on the workpiece relative to the grinding disc, and the trajectory of a certain point on the grinding disc relative to the workpiece. The trajectory curve has a great influence on the machining accuracy of the workpiece, which is mainly due to the parameters that affect the machining accuracy, such as the cutting speed of the workpiece relative to the grinding disc, the direction of the cutting speed, the area where the workpiece can not be machined, and so on, which are closely related to the different trajectory curves.
There are three types of ceramic planar grinders with planetary motion of isolation disc: one is that the upper and lower grinding discs are fixed, and the grinding motion is completely completed by the planetary motion of isolation disc; the other is that the upper and lower grinding discs rotate and the isolation discs are planetary motion; the third is that the lower grinding discs rotate, and the upper grinding discs only float and the isolation discs are planetary motion.
If we want to develop a new ceramic plane grinder, we need the grinding motion and trajectory of the ceramic plane grinder to meet the following requirements: first, the direction of motion of the alloy blade plane relative to the grinding disc should be constantly changing, so as to avoid grain grinding; second, we should make every point on the blade relative to the grinding disc. The grinding distance is equal to ensure that the same margin is removed on the blade, the flatness of the blade plane and the parallelism of the two end planes are maintained, and the wear of the working face of the grinding disc is uniform. Thirdly, in order to adapt to rough and fine grinding, it is necessary to adjust the grinding speed and the conversion coefficient of the speed cycle.
The trajectory of ceramic plane grinder is very important to the quality and efficiency of grinding. Only by mastering the correct trajectory can the grinding accuracy reach a new height.
