- dressing device:
-
- the dressing process can be initiated by:
- -the NC program
- -when a preset spindle load is reached
- -at any time by the operator
-
- in conjunction with the CNC control, machining tolerances are in series
- production of less than 0.010 mm possible
-
- advanced kehren application software:
-
- extensive, machine-specific displays in plain text
- (operating, error, fault messages)
-
- constant circumferential speed of the grinding wheels
-
- approaching the reference points is not necessary, thus reduced start-up time
- of the machine
-
- simple and convenient programming thanks to user guidance and sanding menus,
- supported by color graphics, for example
- 1. internal cylindrical grinding
- 2. external cylindrical grinding
- 3. surface or end surface grinding
- 4. tape grinding
- 5. cylinder compensation
- 6. customized menus on request
-
- compensation of grinding wheel wear
-
- automatic cycles for measuring stop, intermediate dressing and for electronic
