VB Series (Double column Machine Box Way)
(Vision Wide Double column Machine)
Features
VB series, a CNC milling double column/ bridge machining center, applied box guide ways to display Vision Wide’s delicate scrapping and traditional machinery techniques. VB equipped extraordinary heavy-duty cutting ability that met cutting requirements for mold base and components. Meanwhile, there were auto heads attachments for mold surface machining.- Three axes movement is fully supported by Harden box way with low friction.
- Box ways were heat-treated to HRC 50 hardness, and was precisely hand scrapping, then assemble and tune to best accuracy to ensure smooth and precise feeding performance.
- Box-shape with ribs design, main casting structure parts are made of Meehanite grade casting iron with stress- relief heat treatment provides durable, rigid support of the machine.
- Large size Guide ways are designed with optimal span to carry the table, box-shape bed with strong V-shape enforced ribs allows heavy work piece load.
- The best center-line layout of the spindle system, the spindle is close to the Y box way reduce the unbalanced cutting moment and offset of thermal expansion to minimum.
