With the development of industry, the requirements for machining accuracy and surface roughness of mechanical parts are increasing, and grinding is becoming more and more important. Especially in automobile, electric power, shipbuilding, metallurgy, military industry, aerospace and other industries, surface grinder is playing a more and more important role. Thus, the machining accuracy of the workpiece is improved, the machining cycle is shortened and the working area is saved, which brings varying degrees of benefits to people.

Grinder is a precision product in machine tools. To produce precision products, it is very necessary to strengthen technical transformation and overcome key technical projects. In order to improve the "production level of large-scale, CNC, special and precision grinding machines" and strengthen the technical transformation, we will continue to strengthen the technical transformation. Let's talk about how to solve the problem when there are suddenly galling marks on the surface of the grinder.

1. If the marks left during rough grinding cannot be removed during fine grinding, the fine grinding allowance shall be appropriately increased.

2. When coarse-grained abrasive particles are found in the grinding fluid, remove the abrasive debris in the grinding wheel housing and replace the grinding fluid.

3. If the material toughness is too large, alumina grinding wheel shall be selected.

4. When the coarse-grained grinding wheel is just trimmed, its abrasive particles are easy to wear, the workbench speed shall be reduced, the centerless grinding wheel shall be trimmed as fine as possible, and the rough machining shall be carried out at a lower longitudinal speed, or the grinding wheel with finer particle size shall be used.

5. Generally, the material is hard and the grinding wheel is soft; The material is soft and the grinding wheel is hard. However, if the material is too soft, a soft grinding wheel shall also be selected.

6. If the grinding wheel is not trimmed well and there are convex abrasive particles, the grinding wheel shall be trimmed again.

The rise of manufacturing industry will inevitably bring huge business opportunities and new development space to the NC grinder industry. The developing surface grinder should seize this great opportunity, shorten the gap with the world advanced level as soon as possible, improve the overall level of China's CNC grinder industry, create a brand, expand the market, block imports and compete for exports, and strive to greatly improve the domestic market share of domestic CNC tool grinder.
