Standard included equipment

• ATC: 40-tool automatic tool changer for both vertical and horizontal spindles. 
• Tool shank: MAS BT50; pull stud: MAS P50T-2, 60°.
• Tool selection: random shortest-path selection.
• Max tool size: 232 mm diameter when adjacent pots are empty; 110 mm

diameter for consecutive storage.

• Max tool length: 400 mm from taper gauge line; max tool mass: 20 kg.
• AAC: One-station attachment and dust-cover changer, including storage for the L = 300 mm angular attachment and spindle dust cover.
• Angular attachment, L = 300 mm: 22 kW allowable output, 420 Nm torque, 9,800 N thrust, 1:1 speed ratio, 5,000 min-1 maximum speed, ISO No. 50 taper, automatic tool clamping, 5° indexing in 72 divisions, and 20 kg maximum tool mass.
• Slideway covers: Bed, cross rail, and column covers.
• Standard cutting-fluid tank: 180 L, replaced by the larger special tank supplied with this machine.
• Other standard items: Through-spindle-tool and speed-increaser attachment preparation, air blow, spindle speed meter, spindle load meter, three added X-axis datum grooves, three-color status light, automatic power-off after machining completion, constant cutting-load control, five-face machining software, tool/life management, utilization and chip-rate display, maintenance-support display, handheld pendant, work light, ladder, crossbeam handrail, foundation parts, tool box, and standard fuse/lamp spare parts.

Special included equipment

• Large-capacity cutting-fluid tank: 550 L total capacity; 300 L usable capacity between high and low levels; pump flow 30.0 L/min at 50 Hz or 36.0 L/min at 60 Hz; allowable pressure 0.8 MPa at 50 Hz or 0.7 MPa at 60 Hz; 0.75 kW motor.
• Splash cover: Enclosure to control chip and coolant scatter, with an automatic door on the ATC side.
• 5° index-capable five-face machining software, N5S-C5-01: Supports inclined-face machining with a 5°-index, 90° angular attachment. Includes 3D coordinate transformation, attachment-position compensation, work-origin setup, special machining-plane coordinate systems, and automatic Z/W-axis command distribution.
• NC options: Program restart, one-digit F feed command, extra macro variables, 400-program capacity, floppy-cassette directory display, RS-232C remote buffer, 3D coordinate transformation, tool-axis handwheel feed, and 3D rigid tapping.

Monitoring, safety, and support features

• Three-color tower light: Red for alarms, yellow for machining complete, green for NC running.
• Constant cutting-load control: Automatically adjusts feed to stay below a user-set load during heavy milling; the setting must be at least 30% of rated load. It does not protect against sudden crashes or instant tool breakage.
• Tool and life management: Tool IDs up to eight digits, magazine tool-information management, remaining-life/use-time display, and automatic replacement with a spare tool after tool life expires.
• Utilization/chip-rate display: Real-time and accumulated data for the current day, previous day, and prior seven days.
• Maintenance support: Up to 100 machine-alarm history records, alarm details and remedies, peripheral-device status, I/O and sensor status, plus maintenance timing for oils, grease, and batteries.
• Handheld pendant: Emergency stop, coordinate display, manual/jog/handwheel operation, axis and multiplier selection, automatic-cycle controls, feed hold, single block, handle interrupt, feed override, and manual measurement-data readout.

Motors and utilities

• Spindle motor: Low range 18.5 kW continuous / 22 kW for 30 minutes; high range 25 kW continuous / 30 kW for 30 minutes.
• Axis-drive motors: X AC 40/3000i with fan; Y AC 30/1500i; Z AC 30/1500iB; W AC 22/3000iB × 2.
