## Study notes

- Machine construction is based on a frame or portal design to minimise distortion during machining.
- Machine bed, main spindle and front-working tool carrier construction plus overhead bracing provide damping.
- Workpieces are machined from the front, so no angle tools are required; front-working tools are guided on the central block.
- Four compound-rest slides are provided for radial or straight turning.
- Working stroke in all stations can be adjusted independently and steplessly.
- All spindle bearings are oil cooled.
- Adjustable minimum cycle time is under 1.4 seconds, including for double drop production.
