High efficiency grinding

Common processing methods: high speed grinding, slow feed deep grinding and constant pressure grinding, grinding wheel and grinding wheel grinding 1. High speed grinding ordinary grinding wheel linear velocity usually within 30 ~ 35 m/s. When grinding wheel linear velocity increased to more than 45 m/s is called high speed grinding. Productivity can be increased by 30% ~ 40%, the grinding wheel durability improve 0. 7 ~ 1 times, stable workpiece surface roughness Ra value can reach 0. 8 to 0. 4 μm。 2. Slow feed grinding slow feed deep deep grinding depth of 100 ~ 1000 times of ordinary grinding, up to 3 ~ 30 mm, is a kind of powerful grinding method. Mostly through a trip after grinding. Advantages: high productivity, less wear of grinding wheel, grinding quality. Disadvantages: the high cost of equipment. 3. A special form of constant force grinding horizontal grinding. When grinding, regardless of the external factors, such as grinding allowance, degree of hardness, grinding wheel, workpiece materials, grinding wheel is always in a predetermined pressure to artifacts, until the end of the grinding. Constant pressure grinding stable quality, high productivity, avoid grinding wheel overload, safe in operation. 4. Wide wide grinding wheel and grinding wheel grinding wheel grinding is to improve grinding efficiency with increasing the grinding width. Ordinary cylindrical grinding wheel width is about 50 mm, the width of cylindrical grinding wheel grinding wheel width of 300 mm, plane grinding of up to 400 mm, centerless grinding of up to 1000 mm. Wide grinding wheel adopts horizontal grinding, cylindrical grinding, is mainly used in mass production such as grinding spline shaft, motor shaft, etc. Size tolerance grade can reach IT6, Ra value can reach 0. 4 μm。 More grinding wheel grinding is another form of wider wheel grinding. Mainly used in mass production and round the plane grinding. In recent years, the internal grinder also began to use this method, with the shaft hole is used for grinding parts.
