4.2 Technical Data Minimum dividing increment 1 Max. operating range with one indexing movement 90 Push-in depth for release 7 mm Push-in force for release 600 N Recommended feed for push-in movement 1 m/min Recommended feed for dividing movement (depending on machine type and moving mass) 5 15 m/min pickup-points 1-4 push-in depth for release = 7 mm Before Start of Programme: Check precise start position at scale! If necessary, adjust manually to reach the programmed start position! (cf. Manual Dividing, p. 3.0) Notes for Feed Programming: Feed motion with accurate positioning must be used! Switch off standard feed motion! With certain CNC controls dwell time must be used in order to guarantee an exact push-in movement! Page 4.2
4.3 Indexing Tool indexing tool Clamping: into Weldon chuck Ø 20 mm Tightening screw must push into the ringshaped recess at the clamping shaft controll! Measure Tool: Note: The tool length TL refers to the centre of the driving key! Tool Data: List TL and TR (= 0) in tool memory of the control Indexing Tool: Place indexing tool into tool magazine of the machine Change indexing tool into machine spindle Ø 18 TL = to ol le ng th driving ball TR = tool radius = 0 Important: The driving ball of the indexing tool must show towards the indexing device! (an angle deviation of + 3 is max. permissible) Greater angle deviations must be compensated: either: correction through spindle orientation of the CNC-control or: turn indexing tool in the Weldon chuck to the correct position: release tightening screw turn indexing tool fasten tightening screw Simultaneously: observe tool length TL! it might be necessary to measure TL once again!
