Tooling Concept
Use of commercially available, dressable grinding wheels with aluminum oxide or silicon carbide abrasives, or with ceramically bonded CBN crystals. The wheels are dressed on the machine by a CNC dressing device. Alternatively, non-dressable KAPP CBN Profile Grinding Wheels can also be applied.

Features
The design of the VUS P is essentially the same as the VUS except it is equipped with a CNC dressing device, which allows the generation of CNC controlled arbitrary wheel profiles.
Using the D 200 control, a machine control system developed by KAPP , the so-called "GMG strategy" (GMG = Grinding - Measuring - Grinding) can be applied in the process comprising the following sequence of operations:
- Input of gear data
- Generation of both the dressing and grinding program
- Initial dressing
- Grinding of a test slot
- Checking the test slot with the integrated measuring system
- Comparison of the ground profile to the required profile and, if necessary correction of the dressing path
- Second time dressing
- Grinding of the complete gear
Applying this strategy allows to optimize tooth designs and to manufacture highly accurate gears in the shortest possible time.

Options
On-board gear measuring system for in-process inspection of the following gear elements (per DIN 3960):
- Profile
- Lead
- Pitch
- Tooth thickness
Values are measured by a touch probe installed in the working area, then processed by the machine control D200 and displayed on the screen, or plotted and printed out.
Topological grinding:
KAPP has developed the necessary software for topological modifications of the tooth flanks to meet specific gear requirements. Modifications of this type can be introduced on the profile (involute crown) and on the lead (lead crown) of the gear.
