Swivel Head

When processing of complex parts, e.g. multisided machining, machining of holes and planes with different angles and free-form surfaces the swivel head with the following characteristics is used:

  • Lowering of cost per unit due to complex 5-side processing in one clamping
  • High cutting efficiency when roughing and high quality of surface when finishing due to the high retention force of rotary axes
  • High repeatability of workpiece dimensions due to high thermal stability of the standard construction of the machine
  • Wide range of parts can be processed, from light alloys to titanium, as well as inconel and hardened workpieces.
  • High capacity and convenient readjustment due to unique technologies of tool magazines
  • High ergonomic accessibility when operation and maintenance
  • Quick installation and commissioning due to possibility of loading and unloading with crane
Technological advantages
  • Modular machine construction with different types of tables, spindles and magazines allows choosing of machines that conform to specific customers’ requirements
  • Rigid control system with large ball-screws, bearings and profiled guide ways with backlash-free preloaded guiding devices, as well as high static masses of machine beds provide power cutting and wear resistance
  • Digital drives with numerically controlled brushless servo motors have enclosed constructions and are maintenance-free
Main advantages
  • Machines of NBH series are easily integrated into one production line conforming to requirements of customer
  • Rigid machine bed provides reliable working and stable precise processing
  • Designing with high-tech innovative technologies
  • Reliable and long-term investment
  • Easy operation and maintenance
  • Easy integration into flexible multi-pallet storage and automatic production systems
  • cylinder block
  • leg
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 tool changing in the spindle by pick-up system
    • Steel tool holder brackets
  • Disk-type magazine for 60 or 120 tool locations:
    • Storing of tools in special double clamps
    • High positioning accuracy of CNC-controlled disk
    • Quick transporting of tools during machining by means of CNC-controlled drive
  • Rack type magazine:
    • Re-setting of complete tool sets during machining
    • Tool loading station (drawer) allows inward and outward loading of single (worn-out) tools
    • No affection of tools by coolant and chips due to the overhead arrangement
    • Location-coded tools with electronic management
    • Special tool cassettes for large tools increase flexibility
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).
