Rough grinding of the lip is performed manually by holding the cutter against the circumference of the grinding wheel (see Fig. 2). This operation is follow- ed by finish grinding in the machine. The off-center tolerance is .0004 which should be checked with a micrometer caliper (see Fig. 3). To grind the

Here the machine operator can plug in the values from the CNC controls and see what number he obtains. Typical values for Aggressiveness are between 3 and 60, with lower values for finish-grinding and higher values for rough-grinding. Moreover, each wheel/workpiece/coolant combination will have an

Grinding in one setting allows shorter throughput times and considerably raises the quality of the workpieces at the same time. Diagonal Wheelheads Diagonal wheelheads offer the option of rough and finish-grinding in one setting. With the additional use of HF internal grinding spindles even universal external, face and internal grinding are ...

The key indicator for the efficiency of a machine tool is the energy requirement for each good part produced. Through the use of JUNKER grinding machines, this value is continuously dropping. As the number of grinding steps possible in a single machine increases, machine downtimes diminish and precision improves.
