Compact CNC Grinding Machine

The Dominator 624 CNC machine is the smallest in a three-model lineup from Jones & Shipman, yet it is said to offer all the functionality of a high-precision grinding cell in one, compact machine. The machine offers multi-axis creep-feed, surface and profile grinding and a GE Fanuc intelligent terminal CNC within a 2,025- × 1,500-mm footprint. 

The machine’s compact size makes it ideal for use in shops where space is at a premium, but precision, ease-of-use and high productivity rates are still paramount, the company says. The compact dimensions are achieved by using a cuboid machine-bed design and mounting the wheelhead on a carrier assembly to provide the Z axis. The worktable moves vertically to provide a Y axis. In addition to retaining the maximum grinding dimensions within a confined machine envelope, the cuboid machine bed contributes to the machine platform’s rigidity. 

The worktable is supported from the front face of the bed on preloaded precision linear slides. The vertical movement makes loading parts easier as the workholding drops to allow more comfortable access, which is useful when handling large and heavy parts, the company says. 

The machine is also available with a full suite of dressing and grinding programs. Easy-to-follow Windows setup pages allow the operator to quickly digitize diamond and wheel positions, the company says. Graphical images prompt the operator, and spreadsheet-style programming is said to ensure quick and simple input. The option of ISO programming is also available. The maximum grinding length is 600 mm and the grinding width is 200 mm on a 400-mm worktable.
