BM Series

Double Column Machining Center BM Series
  • BM series, a beam moving bridge type CNC milling machine center manufactured by Vision Wide, is specially designed for large workpiece machining which could contain a maximal 2,400mm height of workpieces. Vision Wide applies unique techniques to synchronize W-axis feeding with another axial feeding, and ensure the movable beam’s dynamic straightness and heavy cutting power. We provide X travel from 4,200 mm to 10,200mm, Y travel from 3,000 mm to 4,200 mm, W travel from 1,000 to 1,500 mm, and multi-angle head attachments for automatic machining.

    • BM series 5 faces machines, with typical VW products features of rigid structure and high precision, is unique by the features of movable cross rail and W-axis feed cutting synchronic with another axial feeding. The max. height for workpiece & machining is 2,450mm & 2,400mm.
    • The movable cross rail can be positioned precisely by dual synchronized servo motors driving system. Besides, it can carry precision feeding and heavy cutting on W-axis.
    • The rationing hydraulic system precisely controls the parallelism of cross rail travel, even with different positions of the headstock on the Y-travel. Dual cylinders offer strong support for W-axis smooth movement.
    • Double beams configuration: Fixed beam to keep the best parallelism and maintain the structural rigidity; Movable beam to have the dynamic straightness and sustain the cutting power.
    • A precise clamping device can hold the cross beam tightly, well controlling and supporting the spindle cutting accuracy.
    • Automatic horizontal and vertical tool changer.
    • Automatic head magazine (one head).
    • AH attachment-Automatic 5-face function with 700mm longer Y-travel.
