Wiper and plunging process can be used for a range of different high-volume applications. In gear turning, combined car and wiper plug is usually the best solution. Including the dimensional accuracy and surface roughness of the technical requirements of typical synchromesh gear shown in Figure 5.

The first place is the key cone synchromesh gears. For processing the surface, there are three options: (i) the traditional turning, (ii) insert car, (iii) wiper technology.

Turning is a traditional method of trial cut, and the benchmark car and plug and wiper technology as compared. In conventional turning, cutting speed and feed use were 150-200 m / min and 0.1mm / rev. Interpolation parameters used car: vc = 300m / min, f = 0.04mm / rev. As mentioned earlier, the success of plunging by increased cutting speed and lower feed rate.

Blade uses a groove having a negative angle triangle monolithic secomax cbn100 blades, each blade provides six cutting edges. In the interpolation process in the car, the positional accuracy of the tool is crucial, since it will be copied to the workpiece. When machining cone, it requires the use of special 'custom' arbor to provide 6.5 ° taper, taper the final adjustment to be done on the machine.

The main benefit of plunging is to shorten the cycle time. Plunging feed rate of 0.04mm / rev, cutting depth 4 turn feed plus a very small space, for a total exposure time of 0.04 seconds to complete, while the traditional turning needs 4.96 seconds, the gap is more than 100 times.
