Prior to grinding, a number of stages are involved in gear manufacturing hobbing is a roughing operation which produces a gear profile with stock remaining for a final grinding process see figure 1. hardeningheat-Treating is a group of processes used to alter the physical, and sometimes chemical, properties of a material.
Jun 29, 2020 Belt grinding has become an important production process, in some cases replacing conventional grinding operations such as the grinding of camshafts. Belt speeds are usually in the range of 2,500 to 6,000 ftmin. Machines for abrasive-belt operations require proper belt support and rigid construction to minimize vibration.
The severity of the grinding operation also influences the choice of grade. Hard grade provide durable wheels for rough grinding such as snagging, while medium and softer grade wheels can be used for precision type operations which are less severe on the wheel. 5. The speed at which the grinding wheel is to be operated often dictates the type ...
