High Precision Horizontal CNC Internal Grinding Machine with Max.ID 500mm
High Precision Horizontal CNC Internal Grinding Machine with Max.ID 500mm
● Grinding Diameter Range:6-320mm
● Grinding Accuracy:Ra 0.32µm
Δ This machine is a two axis (X-axis, Z-axis) CNC Internal Grinder, which is mainly used to grind the inner hole, step hole, iner end face and outer end face of the work piece. The grinding cycle is completed automatically
Δ (with automatic feed,withdrawal , rough grinding and finegrinding); Automatic dressing of grinding wheel,automatic compensation, etc.
Δ The machine tool is fixed by the work piece box, the worktable moves left and right.and the grinding wheel frame do the back and forth fedingmovement. The movement of the worktable and grinding wheel frame is driven by the servo motor through the ball crew, both of which adoptlinear guide rails.
Δ The rotation speed of work piece spindle and grinding wheel spindle are controlled by frequency converer to reaize stepless speed regulaton.
Δ The machine tool adopts a front movable operation box and an independent electrical cabinet. The protective cover shell has two differentstyles of semi closed or fully closed for users optional.
