Wiper and plunging process can be used for a range of different high-volume applications. In gear turning, with plunging and wiper blade is usually the best solution. Including the dimensional accuracy and surface roughness of the technical requirements of the 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) plunging, (iii) wiper technology.

Conventional turning a test cut method, and reference and plunging 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 integral secomax cbn100 blades, each provide six cutting edges. In plunging machining, the tool position accuracy is critical, as it will be copied to the workpiece. When machining cone, it requires the use of special 'custom' arbor to provide 6.5 ° of taper, the taper of 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 in turn 4 plus minimal air feed, for a total exposure time of 0.04 seconds to complete, while the traditional turning requires 4.96 seconds, the gap more than 100 times
