Rolling Deburring Discs

Rolling deburring discs are used for creating chamfers on the teeth at both faces of the gear. Rolling deburring discs are available with an additional smoothing disc to minimise waste on the faces of the gear workpieces. Various chamfer versions such as: - Parallel, - Comma-shaped or - Parallel with chamfers at the root of the teeth are also available with face-bevelled workpieces. The tools are supplied already presetted and can be used for chamfering gears with the same gearing parameters and the same tooth width, if there is no risk of collision with the workpiece contour. Economical use of tools is guaranteed with the option of reversing the rolling deburring discs. When the wear limit of the rolling deburring discs is reached, the discs can be reversed and set up again in a very short time to re-use the tool.

Field tests have clearly shown that the mathematical mastery of the process and the coordination thereof to tool and machine is the key to success. This was proven during customer trials. - Two to five times faster than gear shaping - One to two quality grades better than gear shaping - Excellent single indexing quality at the workpiece - Tool life similar to gear shaping - Available tool designs: conical and cylindrical - Process-optimized tool design - Tools available in PM-HSS and carbide (also with indexable inserts) - Dry skiving possible - Pressure angle and lead modification possible

Flexible rolling chamfering discs are used with the same workpiece gearing parameters and different tooth widths. They can be supplied in sets or with holders for a specific tooth width. As with the rolling deburring discs, the chamfers on the teeth at both faces of the gears can be parallel, comma-shaped or parallel with chamfers at the root of the teeth. The rolling chamfering discs can be designed for wet or dry machining. An additional coating extends the already long tool life even further
