This machining unit is the most progressive and most universal in the market:

  • Rotates around the Z-Axis 
  • 400W-Servomotor, torque max. 2 Nm
  • Toothbelt ratio approx. 1:2,2
  • Supervision of the speed 
  • Speed, rotation direction and angle freely programmable
  • Reference run 0° for angle positioning
    • Angle resolution 0,25°/step  
  • Universal use  - 
    • Particularly low-noise spindle
    • for drilling, milling, engraving....
    • cutting threads, as tangential cutter, ..... 
  • Speed range approx 50 .... 12.000 rpm 
    • can be customized
  • Chuck ER16, DIN 6499 B, 426E
    • 3 or 3,17 mm (high security level)
    • up to 10mm (industry) 
  • Sound level (without machining): < 50 dB .... < 70 dB
  • Weight approx. 2,5 kg
  • C-axis controller for servo must be integrated in control unit
  • High load/stress (only together with KS432 - package, professional rollers, etc.) 

The HighPower C-axis is auch mit automatic toolchanger. In this case a tool receiving socket with steep taper is changed (pneumatically), so tools with different shaft diameters can be used. For more details contact us. 

To work on workpieces (milling, drilling, engraving a.o.m.) you need a machining unit (MU). It is fixed to the Z-table of the CNC-machine.

The machining unit consists mainly of an electrical driven spindle. And a clamp to fix the tool (mill, drill, engraving router a.o.m.) in different diameters.

Notes for machining

Our HighPower-C-Axis as machining unit for drilling, milling, engraving, etc. needs suitable machining parameters which regards its technical features. Background knowledge:

A servomotor drive has got certain characteristics:

  • Servomotors are very dynamic (fast change of speed, good controllability) and very powerful. This requires a high load tolerance of the linear axes, therefore you must choose machines with high load capacity.

  • Servomotors have got an integrated encoder (rotation supervision and angle control), which provides a constant position even at standstill. Therefore, the motor must be shut off for manual tool change (Software function).

  • Servomotors are extremely maintenance-free, without brushes and current transmission elements towards the rotor (collector), nor ventilator. However, a servo-amplifier (control- and amplifier electronics) is required, which will normally be housed behind the body (Portal). A small ventilator is built in there.

  • Servomotors are extremely low

  • Servomotors and spindles are separated from one another, this means: flexible transmission ratios when needed (Standard 40:18), easier maintenance, spindle can be modified.

The total programmability of our HighPower-C-Axis allows its use in the following range of applications:

  • as milling/drilling/engraving spindle

  • to position angles

  • to use with special tools with inversion of rotation direction, like thread cutting, cutter, oscillating tools
