The grinding wheel should be trimmed in time. The grinding wheel should be trimmed coarsely during rough grinding. The grinding wheel should always be sharp during fine grinding to avoid overheating and burns. No burrs are allowed at the corners on both sides of the trimmed grinding wheel.
When grinding with low surface roughness, rough and fine grinding should be carried out separately, and the fine grinding allowance is generally 0.05 mm, and 0.1 mm can be reserved when the workpiece clamping error is large.
The grinding process must be sufficiently cooled to take away a large amount of grinding heat and scour to prevent the grinding wheel from being blocked and the surface of the workpiece from being burned. The coolant must be clean and free from abrasive debris or grit that could ruffle the workpiece. The coolant for grinding stainless steel is generally an emulsion with better cooling performance, or a coolant containing extreme pressure additives and low surface tension. The flow rate is 20 to 40 L/min, and when the diameter of the grinding wheel is large, it is 80 L/min.
The grinding allowance of stainless steel should be smaller. During cylindrical grinding, the grinding allowance on the diameter is 0.15 to 0.3 mm, and the fine grinding allowance is 0.05 mm. The allowance for internal grinding is basically the same as for external grinding. When surface grinding, for parts with small area and good rigidity, the one-side allowance is 0.15-0.2 mm, and for parts with poor rigidity and large area, the one-side grinding allowance is 0.25-0.3 mm.
PVD coating is suitable for cutting tools (milling tools, turning tools, knives, drill bits, etc.), plastic molds, metal molds and precision parts. Their lifespan can be increased by 3-5 times after coating, increasing wear resistance, corrosion resistance and reducing friction.
