125E / 140E / 160E / 200E / 250E

CNC Vertical Boring & Turning Mills. Heavy Duty, High Precision, Vertical Boring and Turning Mills. Designed to Deliver Superior Performance

High Productivity

  1. Maximum 1250 to 3000mm turning capacity
  2. Maximum 4 to 15 tons load capable table
  3. Elevating cross rail of 700 and 1000mm travel
  4. Full controlled C-axis and rotary spindle (only for VTC)
  5. Automatic tool changing system up to 12/24 (VTB/VTC) tools

High Reliability

  1. Heavy duty, wide guide ways of box type
  2. Massive one-piece cast iron bed, column, saddle, and cross-rail
  3. Induction-hardened and precise-ground guide ways
  4. Extra large 220, 240 and 280mm square spheroidal-graphite-iron ram
  5. The saddle enclosing the ram is one-piece casting to keep the high rigidity

High Accuracy

  1. Qualified precision bearings & ball screws
  2. Fluoroplastic-bonded & hand-scraped guide ways
  3. Full automatic lubrication to all critical areas

Machine Construction

The column, cross rail, bed, saddle, and table are constructed of high quality Meehanite cast iron. These main components are densely ribbed, thick walled, and fully stress relieved for long lasting accuracy.

Ram & Saddle

  1. The saddle enclosing the ram is one-piece casting to keep the high rigidity.
  2. huge 220, 240 and 280mm square spheroidal graphite iron ram,hardened and ground, is encased in the heavily ribbed saddle and is hydraulically counter balanced.
  3. Low friction fluroplasitc resin bonded to the ram sliding surfaces of the saddle minimizes friction.
  4. ModelVTC has milling spindle with high-speed that involves drilling, milling, and tapping.
  5. Pull stud tool mounting and dismounting way of machining center type(P50T-I / DIN. 69872.50).
  6. Automatic metered lubrication system ensures lasting accuracy.
  7. Tool fall-safety device assures safe operation.

Elevating Cross Rail

Vertical positioning of this massive cross rail is hydraulically powered. Positioning accuracy is assured by automatically actuated precision pins and 37.4 tons of hydraulic clamping force.
