Knuth CNC Gantry-Type Machining Center PBZ Heavy 3220

 

Power - Performance - Precision

 
  • bed, columns and travel tracks form a solid frame structure for high rigidity under hard machining conditions and high table loads
  • triple linear guides support the table across its entire travel distance in the X axis and allow high table loads
  • all axes feature preloaded ball screws, preloaded spindle nuts and powerful drive motors
  • quadruple linear guides of headstock on Z axis ensure maximum rigidity even with extra-long lay-outs
  • the included hydraulic spindle gears allow a wide speed range and high torque
  • including weight balancing system for easy movement and precise Z axis positioning
  • the main spindle features an oil cooler to ensure constantly balanced temperatures
  • quick tool changes via a tool-changer with dual-arm gripper
  • Fanuc 0i MD control with Manual Guide for easy programming and maximum reliability
  • chip conveyors on both sides of the table with a capacity of 55 kg/min ensure quick chip removal from workspace; including chain-type chip conveyor
  • Productivity and flexibility can be increased even further by using any of the optional accessories: NC – Rotary Table, 90° Angle Cutter (more accessessories upon request)
  • automatic central lubrication system
