US - 400 STEP

Purpose Main spindle
  • Numerical lathe US - 400 STEP is designet for manufacturing of single and serias production of parts with diametars up to 415 mm. Contemporary structure of the lathe and simple handling enables economic machining. Increase of productivity is achived SIEMENS - SINUMERIC 802 C numeric control.

  • Hight rigidity of the main spindle, which is in highly precise bearings - TIMKEN, ensures high quality machining.

Slide ways

Screw spindle
  • Slide ways are hardened and grinded.

  • Very precise hardened and grinded ball crew spindle for X and Y axis.
