Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grinding machine design, especially to an easy-to-dust double-disc grinding machine. BACKGROUND

[0002] The double-disc grinding machine is a mechanical device for grinding and flattening both sides of a workpiece simultaneously. It achieves efficient grinding of the workpiece surface through the relative movement between two parallel grinding discs (one on top and one on the bottom), and is widely used in the precision machining of various materials.

[0003] In the grinding process of some existing double-disc grinding machines, the cooling water is usually sprayed on the grinding disc to be cleaned, and then an auxiliary brush is used to clean the dust. However, it is difficult to maintain uniformity of the spray by relying on manual operation, which may cause local overheating of the workpiece and the grinding disc, resulting in deformation of the workpiece or damage to the grinding disc. In addition, the accumulation of grinding debris and dust may affect the grinding effect, increase the cleaning difficulty, and reduce the production efficiency.

[0004] Therefore, there is an urgent need for an easy-to-dust double-disc grinding machine to solve the above technical problems. SUMMARY
