Interpretation of factors affecting the grinding effect of processed objects
Grinding is the grinding tool (hereinafter referred to as the grinding tool) surface embedded abrasive or coated abrasive and add lubricant, under certain pressure, the tool and the grinding tool contact and do relative movement, through the abrasive action, from the workpiece surface cut a layer of very thin chip, so that the workpiece has a precise size, accurate geometry and high surface roughness. The essence is to use free abrasive grains to carry out micro-cutting including physical and chemical comprehensive effects on the surface of the workpiece through the grinding tool.
Features:
(1) In mechanical grinding, the machine-tool-workpiece system is in an elastic floating state.
(2) The workpiece to be ground is not subject to any force and is therefore in a free state.
(3) The speed of the grinding movement is usually below 30 m/min, which is about 1% of the grinding speed.
(4) When grinding, only a very thin layer of material can be cut off, so the heat generated is less, the processing deformation is small, and the surface deterioration layer is also thin.
(5) There is residual compressive stress on the grinding surface, which is beneficial to improve the fatigue strength of the workpiece surface.
(6) The operation is simple and generally does not require complicated and expensive equipment.
(7) Adaptability is good.
(8) grinding can obtain very low surface roughness.
