MITSUBISHI DIE MANUFACTURING MACHINE FM SERIES

Rugged Machine Structure
Mitsubishi's original CAE System, FEM Dynamic Characteristics Analysis and Heat Analysis Methods, combine to produce a rugged and optimum structure bed, column, headstock and so forth.

Low Vibration Main Spindle
Optimum Spindle Size and Bearing Arrangement:
Spindle torsion and deflection minimized by applying Mitsubishi's Rotor Dynamics technology.

Precise Balance Adjustment:
The combination of a rugged machine structure, super accurate main spindle parts and precise balance adjustment results in the lowest main spindle vibration within the machine tool industry.

Improved Main Spindle Rigidity:
The rigidity of main spindle is improved by adding thickness to the spindle end and minimizing the distance between the front bearing and spindle end.

Stable Unit Feed Mechanism

• Application of Large Diameter Small Lead Ball Screw:
  Ball screw with ample diameter and small lead results in stable feed motion unaffected by load variance and/or speed variance.
  
• Application of Ample Capacity Servo Motor
  The application of servo motors having ample capacity results in remarkable response improvement and speedy, accurate and consistent unit feed motion.

MP Scale to Maintain Machining Accuracy Equipped as Standard
A consistent machining accuracy maintained regardless of the error of mechanical parts due to secular change. Thanks to the MP Scales applied to all moving members of the machine.

Thermal Displacement Compensating System Originally Developed by Mitsubishi Equipped as Standard
A long term unmanned operation made possible by furnishing a thermal displacement compensating system as standard. This enables to eliminate position adjustment control during machining resulting to an astonishing positioning error of only ± 10 um ± 0.0004 in/day even at cold start.
