Control
- Num Axium Power

32 BIT - Cad/CAM Graphical user interface for creating CNC machining programs in 3-axis operation

Bypass range
- With a tool exit length of 100 mm (from the lower edge of the spindle = 180 mm) and a diameter of 100 mm:
- Length (X): 5,000 mm
- Width (Y): 1,500 mm
- A-axis: +/- 95°
- C-axis: +/- 210°
- Clearance height: 200 mm (upper edge of suction cup, total travel in Z direction approx. 700 mm)
- The safety distance is 5 mm.

Machine table
- Grid table (grid 50 x 50 mm) made of plywood with integrated stops

Workpiece positioning / workpiece clamping
- 4 zero points (stops) at the front left 2x and right 2x for alternating loading (pendulum machining incl. vacuum monitoring: filter and control integration of 2 machining stations (2 vacuum valves)
- 8 pneumatic stops permanently integrated in the front part of the table

Robot head + tool spindle
1 machining unit for machining:
- Aluminum or aluminum alloys
- All types of plastics
- Synthetic resin
- Resins for metal
- Wood
- Graphite for electroerosion
- Glass and/or carbon fibers
Replacing or maintaining the electric spindles has been made much easier thanks to the option of pulling the spindle out of the housing of the electric unit.

- The robot head (A-axis) is mechanically/pneumatically locked (automatically locked/unlocked) for 3-axis operation.
- A-axis: +/- 95°
- C-axis: +/- 210° (420° in total)
- Polar axis speed in continuous operation (in operation): 200°/sec
- Polar axis speed in fast positioning: 200°/sec
- Nominal torque in continuous operation: 580 Nm
- Positioning accuracy of the polar axes after an oscillation of 180°: +/-0.02 mm (rotary encoder 200 rpm)

Electric spindle
- HSK 63 F connection
- Automatic tool change with air cylinder
- Power approx. 12 kW in S1 operation (peak power = 22 kW)  24,000 rpm - 4-pole motor 380 V
- Precision angular contact ball bearings with ceramic balls
- Permanent lubrication with high-speed special grease
- Liquid circulation cooling integrated in the electric spindle
- Overheating protection (bimetal) integrated in the motor, which activates at 120-130°C
- 2 inductive sensors type PNP N/O for checking the tool release piston in the retracted and extended position (tool unlocked).
- 1 inductive sensor type PNP N/O for tool presence control
- Cone cleaning with compressed air through the spindle shaft during tool change
- Pneumatic dust protection barrier on spindle nose and mechanical labyrinth
- Simple and quick replacement of the electric spindle
- Integrated chip extraction

Tool change magazine
- 1 automatic tool change magazine for 12 positions (plate changer) moving in the X direction.

Additional tool position
- 1 piece, as pick-up position for e.g. adapter with saw blade (max. Ø 350 mm)

1 piece drilling unit, 10-spindle
- 6 spindles vertical in X direction
- 4 spindles vertical in Y direction

- Grid dimension: 32 mm
- Anti-rebound power: 2.2 kW
- Direction of rotation: right/left
