CNC lathe sheet moving chuck clamping work pieces

The four claws of the CNC lathe sheet movement tray can be moved independently, as the back of each claw has a half-valve internal thread meshing with the screw, the screw

There is a square hole at the end, and when a square hole is turned with a chuck wrench, the corresponding screw is driven to turn so that the claws can be clamped or loosened. As a result, CNC lathe sheets can be loaded with square/rectangular/oval and irregularly shaped work pieces, as well as turning eccentric shafts and holes. Therefore, the CNC lathe sheet moving chuck clamping force than the self-determined new chuck master is used to clamp a larger diameter of the normal circular work pieces.

CNC lathes with a single-move chuck clamping work piece, because the four claws out of step can not be automatically centered, need to be carefully corrected, so that the axis of the work piece is aligned with the spindle rotation axis. Use the dashing disk to find the positive by the round surface inside and outside the work piece or the pre-defined processing line, positioning accuracy at 0.2-0. 5mm, with a percentage table by the finished surface of the work piece to find positive, can reach 0. 01 -0. Positioning accuracy of 02mm.

When the parts of the work piece processing balance is not uniform, should focus on finding the parts with less positive balance, otherwise it is easy to scrap the work piece.

CNC lathe sheet movement chuck can all use positive grasp or anti-grab clamp work pieces, can also use one or two back-grabbing, the rest still use positive grip clamping work pieces.
