Description

The UNION KC-150 is a 5-axis boring mill for the efficient complete machining of larger prismatic workpieces. The horizontal drilling and milling machine with movable column is equipped with a working spindle Ø 150mm and a tool magazine with 60 magazine places and automatic tool changing system. The work table with a clamping area of 2,000 x 2,500 mm can carry workpieces weighing up to 20 tons. The main spindle has a maximum torque of 2,179 Nm and can deliver up to 46kW at 3,000 rpm. A coolant system with paper band filter system, internal (20 bar) and external (3 bar) coolant supply as well as a special rotary housing, mounted on the table, complete the configuration of the UNION KC-150.

Accessories:

 

  • Partial enclosure of the work area, special enclosure at the table - movable all round
  • Operating mode 3
  • Chip conveyor between table group and Z-bed
  • Coolant system for internal & outside cooling 30l/20 bar, 50l/3 bar
  • Coolant cleaning by band filtration unit, coolant tank content 990l
  • Tool magazine 60 places, automatic change
  • Support bearing
  • Torque monitoring of the working spindle
  • Minimum lubrication instead of emulsion coolant
  • 3D remote radio touch probe

Design features
Machine
Backlash-free ball screws in all linear axes Direct, absolute linear scales in all axes manufacturer HEIDENHAIN  
Column – machine bed
Broad, strongribbed steel construction Pretensioned compact roller linear guides for backlash-free guidance of the slides Column and machine bed can be set up separately from each other  
Column
Massive ribbed cast-iron column in box design Pretensioned compact roller linear guides for backlash-free guidance of the headstock Full covering on column for the vertical movement of spindle  
Spindle unit
Rigid casting design Bearing of spindle unit with high-precision pre-tensioned angular contact ball bearings, lifetime lubricated mounted in the forward fixed spindle extension Automatic shifting of the two speed series via auxiliary gearbox with hardened gears and oil cooling Power transmission to boring spindle via low-noise V-belt transmission Nitrogen hardened high-precision balanced boring spindle, axially adjustable, can be positioned in any angle, guarded against coolant and chips through labyrinth seal  
Table group
Cast iron table, slides with pre-tensioned compact roller linear guides with high rigidity, together with the headstock vertical adjustment, guarantee stick-slip-free circular interpolation. B-Axis with low-friction, hydrodynamic sliding guide with plastic coating. Backlash-free table adjustment (B-axis) with optimized double pinion drive. Table bearing with a radial and axial precision roller bearing. Table underside with plastic-coated sliding guide Hydraulic segment clamping
