LBM-1000

Bridge Type Machining Center

LBM-1000

Bridge Type Machining

The newest eumach bridge type vertical machining center not only with further innovations in rigidity, accuracy, speed and heavy cutting but also for true die / mold evolution.

A very wide door opening allows heary workpiece load / unload directly from the table top side crane to make the operator,s job more straight-forward and enhances safety and productivity.

Totally enclosed guarding includes top side of roof to keep all the chips, water and noise inside of machine to have a clean, quiet and comfortable working environment.

A screw chip auger under machine central bed delivers efficiently chips to the chain type or scraper type chip conveyor & bucket, both are standard equipment.

LBM-1000 chain type chip conveyor

A chain type chip conveyor provided as standard.

Features

  • Large workpiece load & traverse capacity
    1100 mm x 600 mm x 500 mm traverse, 700 mm twin column distance, 1220 mm x 600 mm table size with up to 1500 kg workpiece load.
  • Rigid double column bridge type construction
    The twin column & bridge is made of one piece Meehanite highest quality casting to ensure its rigidity and reduce vibrations during high speed heavy cutting.
  • Wide choice of spindles with full power range
    Various built-in motor spindle from Standard 24000 rpm, HSK-A63, or 30000 rpm HSK-E50.
  • Advanced latest CNC digital controls
    Fanuc 31i, Heidenhain iTNC-530/640, Siemens 840D.

Rigid Overall Machine Design & Superior Features

Rigid one piece castings bridge & twin columns

  • The wide distance 700 mm between twin column, allowing the most convenience mounting of medium workpiece, fixture or rotary table etc.
  • Thermal influences are mini-mised, due to short distance between spindle axis and portal.
  • Permanent motor spindle cooling system.
  • Machine bed is a thermally symmetrical design.
