JUMAT 6S 18-20-18 Grinding Machine

With the new JUMAT 6S 18-20-18, the engineers at JUNKER have once again expanded their proven portfolio. The simultaneous use of three grinding wheels guarantees maximum quality by utilizing a single clamping set up with an extremely short grinding time, according to the company.

All wheelheads feature a separate X-axis and Z-axis, which enables simultaneous workpiece grinding with all three grinding wheels. One grinding spindle ensures precise taper and plane surfaces (Z/X 1), another takes care of the shoulder (Z/X 2), while the last spindle grinds the internal diameter and shoulder (Z/X 3).

Further advantages include the redevelopment of the gearwheel grinding, which is based on the use of an ideal workpiece support. This ideal support is achieved through the center clamp, consisting of hydrostatic bearing and precision power chuck. The center clamp enables the workpiece to be ground simultaneously and on both sides.

The JUMAT 6S 18-20-18 reportedly shows the potential that lies behind optimizing every little detail for precision manufacturing technology.

  • chuck

    chuck

    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
