P 900 CNC - reference machine,
RETROFIT OF CONVENTIONAL MACHINE TO
CNC CONTROL SIEMENS 828D solution line
| max. job diameter: | 900 mm |
| max. module: | 14 mm |
| overall travel Z: | 492 mm |
| overall travel X: | 500 mm |
| overall travel Y: | 200 mm |
Scope of recondition:
- radial and axial axis are controlled by the NC- control
- if the hob head has a tangential slide: tangenial axis as third axis
- exchange of the complete electric and electronic parts
- new electric cabinet
- CNC- control Siemens 828 D
- machine operator panel Siemens 828 D with colour screen
Options: (especially for conventional Liebherr – gear hobbers)
- modification of the radial axis
(removal of hydraulic feed system and assemblage of ballscrew and related parts,
implementation in the NC- programs) - improved accuracy for the working cycle
