Principle of precision guide grinding

Precision guide grinding is a special equipment for processing guide rails, which is mainly used for grinding and dressing the surface of guide rails, so as to improve the accuracy and flatness of guide rails. Its principle is mainly to use abrasive to process the surface of the guide rail, in the grinding process, the abrasive and the surface of the guide rail shear action, so that the uneven part on the surface of the guide rail is destroyed and removed, and finally achieve the purpose of dressing the guide rail.

The principle of precision guide grinding can be divided into the following aspects to explain in detail:

1. Selection of abrasives: abrasives are one of the key factors for guideway grinding. Abrasives with high hardness, strong compression resistance and good grinding effect are usually selected as grinding tools. Common abrasives are silicon carbide, alumina and so on.

2. Generation of grinding force: The force exerted by the abrasive on the surface of the guide rail during grinding is called grinding force, and the relative motion between the abrasive and the surface of the guide rail produces friction, so that the abrasive grinds the surface of the guide rail.

3. Grinding mode: Precision guide grinding can be used to trim the surface of the guide rail by flat grinding or ring grinding. Flat grinding is to grind the abrasive parallel to the surface of the guide rail, and ring grinding is to grind the abrasive perpendicular to the surface of the guide rail. Guides of different shapes and surface roughness can be obtained by grinding in different ways.

4. Selection of grinding parameters: When grinding the guide rail, it is necessary to select the appropriate grinding parameters according to the parameters of the guide rail material, hardness, surface roughness and so on, such as abrasive size, feed rate, grinding depth, etc., to ensure the grinding effect and the quality of the guide rail surface.

5. Control of the grinding process: precision guide grinding needs to be monitored and adjusted in time during the use of the grinding process to ensure the grinding effect and the accuracy of the guide surface, and pay attention to the uniform distribution of grinding force, the contact state of abrasive and guide rail and other factors during the grinding process.

In general, the principle of precision guideway grinding is to use abrasive to grind and trim the surface of the guideway, by controlling the grinding force, selecting the appropriate abrasive and grinding parameters, and controlling the grinding process to improve the accuracy and smoothness of the guideway. Only in strict accordance with the principle of operation, in order to obtain satisfactory grinding effect and guide rail surface quality.
