CNC portal milling machine OPTImill FP 4200


CNC portal milling machine OPTImill FP 4200


Short description

  • Perfect structures and robust construction guarantee maximum rigidity and stability.
  • All main components – bed, work table, column, crossbeam, saddle and headstock are made of high-quality MEEHANITE® quality castings
  • Generously dimensioned guides in the X, Y and Z axes
  • All guideways are hardened and ground (HRC50 -HRC55).
  • The X and Y axes are equipped with roller linear guide. As a result, the axes move with the highest precision even at high speed.
  • Greatest machining accuracy and high damping thanks to wide, adjustable flat guides of the Z-axis for high drilling and milling performance with high spindle output torque
  • Hardened and precision ground recirculating ball spindles mounted in high-precision bearings in all three axes for high rapid traverse speeds
  • Cooling of the main spindle gear (gears, bearings, spindle) through an oil circulation system. Reduction of thermal expansion
  • Operating status display (end of work light)
  • Axle covers
  • Work lamp
  • Air pistol/water pistol
  • Heat exchanger
  • Spindle holder SK50 with a maximum spindle speed of 8,000 rpm with 2-stage gear for high precision
  • Pneumatic counterbalance of the Z-axis ensures very high reliability and stability while multiple axes work at the same time. The SCBS system does not require an additional power supply or drive. This balance system achieves high speed and high processing precision
  • Complete machine cladding with wide-opening doors for ergonomic workpiece handling
  • Automatic lubrication system with pressure control system
  • Separation system for lubricating oil and coolant
  • Installation elements
