## Study notes

- Spindle speed range is 35 to 12,000 min⁻¹ on the standard 4-step gear driven, dual-contact spindle; an 8,000 min⁻¹ high-torque spindle is optional.
- Tool change time is 2.1 s tool-to-tool and 4.8 s chip-to-chip at minimum.
- Positioning accuracy is stated as ±0.001 mm over full stroke.
- Standard automatic pallet changer has 2 stations; 8, 14 and 21 station APC configurations and additional tool storage (122, 162, 212 tools) are field-expandable options.
- Table and pallet size is 500 x 500 mm; the stated work envelope is 800 mm diameter x 1,100 mm high.
- X/Y axes use a patented twin ballscrew arrangement with dual feedback; a 67 million pulse encoder and scale feedback are used on all axes.
- The machine control is the Arumatik-Mi CNC with Super Smooth Surface control, featuring a touch-screen icon interface.
- Spindle motor is rated 54 HP; the stated power requirement is 75 kVA at 200 V AC, 3-phase.
- Optional spindle taper is HSK-A100 in place of the standard NST No. 50.
- The 4th axis rotary table is direct-drive motor driven.
