spindle design: high speed, high precission and high rigidity concept


HIGH RIGIDITY STRUCTURE

Structure YV 200-800 Series
  • The rigid vertical column and base are Meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening. It is designed for turning of medium sized workpieces.
  • The X and Z axis linear guideways are completely enclosed and a forced lubrication system assures high precision. The high speed linear way system enables rapid traverse rates of 20 m/min.
  • The precision class 3 ballscrews are driven directly by the servo motors, eliminating belts or gears for high precision.
  • The 30 HP high torque Fanuc spindle motor provides more torque at a lower RPM and delivers power for heavy duty machining and high speed for fine finishing.
  • The 10 position hydraulic turret provides for .5 second index time and shortest route tool selection. A live tool turret is available as an option.
  • The spindle construction is a heavy duty design incorporating high precision double roller bearings and 45 degree angular contact thrust bearings. The spindle also is protected from coolant contamination. The NN type spindle bearings are used to endure high centrifugal loads and big spindle loads.
  • A monitoring and a filtering unit checks the quantity of oil fed to the main bearing ensuring a long life for the main spindle. An alarm message will be displayed automatically if a fault in the system is detected.
