NBH 800 5X

Tilting-Rotary table

The tilting-rotary table is particularly designed for processing of complex workpieces from different sides with drilling of holes and machining of surfaces with different angles as well as free-form surfaces:

• Complete processing in one clamping (5-axis machining in one clamping)
• Usage as a positioning axis or for simultaneous machining
• High moment of tilting/rotation and feed at A-axis due to backlash-free double worm gear drive
• All proven NBH spindles with high torque and performance for highest accuracy requirements can be used

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

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 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).

Standard CNC Siemens Sinumerik 840D sl:

• Efficient 32-bit modular CNC microprocessor
• Digital drive technology
• Absolute or distance-coded position measuring system:
  • Start-up time converges to zero
  • There are no limit switches at axes and reference switches
• User interface based on WINDOWS operation system:
  • CNC operator panel with 12‘‘ TFT colour display and integrated keyboard
  • Convenient adjustment due to the operator panel of tool magazine
• Advanced CNC functions:
  • Tool management with technology of automatic tool changing in pairs
  • Tool wear quantity monitoring
• Standard Ethernet and USB connections.

Tool management function allows interactively determining required space. Automatic system of tool placement allows using every millimetre of magazine space taking into account adjacent locations and excluding collisions.

Diagnostic functions:

• Eligible text of error messages
• Storing of machine and production data
• Remote diagnostics and maintenance
