Motor and gear spindles

Wide range of motor and gear spindles with different torques and speeds allows choosing of equipment that fully conforms to production requirements. Wide range of options allows precisely choosing the machine configuration that completely conforms to a specific production task. Cylindrical motor and gear spindles are easily replaced, thus providing easy and quick maintenance and exploitation.

Advantages of motor spindles:

  • Short acceleration and breaking time
  • Enlarged maximal speed
  • Low level of noise and vibration during working
  • Contactless pressurization system with compressed air

Advantages of gear spindles:

  • Automatic two-step gear changing
  • High concentric accuracy during rotating due to three bearing supports. Extreme rigidity
  • Bearings with large diameters (100 and 130mm). Optional steel bearings for heavy duty cutting
  • Labyrinth sealing and pressurization prevents ingression of coolant and/or dirt, thus enlarging lifespan of the unit
  • Optimized plunge milling/turning for manufacturing of parts with complex geometry and clamping devices. Spindle tube liner with minimal overall dimensions.
Modular tool magazines

Choosing of an individual tool magazine conforming to production needs of the customer. Wide range of options for tool magazines of NBH machines allows choosing of optimal solution for your production:

  • Disk-type magazine with Pick-up system for 40 tool locations:
    • Proven, reliable and cost-effective
    • Quick changing of tools in the spindle by pick-up system
    • Steel tool holder brackets
  • Rack type magazine:
    • Quick electromechanical tool changing device with automatic mechanical clamping when swivelling
    • Tool station for loading/unloading of tools during machining
    • Taper cleaner is integrated into tool changing unit
Hydraulic clamping

2- or 6-line hydraulic clamping that is activated inside of the setup station of the working area. Optional pneumatic version.

Workpiece measuring

Measuring probe with infrared data transmission for measuring of workpieces or/and clamping devices during processing. Tool changing unit automatically mounts the measuring probe at the spindle.

Tool monitoring

Upgrading of the monitoring system to the full safety package for fully automatic production.

Tool management system Huller Hille
  • Tool wear/lifespan monitoring system. Automatic changing of pairs of tools
  • Tool breakage detection inside of the tool magazine during machining
Clamping head for 4-stage milling and drilling

Transferring of high torque and cutting force to power drilling and milling heads (up to 50 kg).
