With the new JUMAT 6S 18-20-18, the engineers at JUNKER have once again managed to extend their current portfolio. The new machine guarantees maximum quality through complete grinding in a single clamping set-up with an extremely short grinding time, thanks to the simultaneous use of three grinding wheels. All wheelheads feature a separate X and Z axis which enables workpieces to be ground simultaneously with all three grinding wheels. One grinding spindle ensures precise taper and plane surfaces (Z/X1), another takes care of the shoulder (Z/X2), while the last spindle grinds the internal diameter and shoulder (Z/X3). Further advantages include the redevelopment of the gearwheel grinding, which is based on the use of a perfect workpiece support. This is achieved through the center clamp, consisting of hydrostatic bearing and precision power chuck. This enables the workpiece to be ground simultaneously and on both sides.
The JUMAT 6S 18-20-18 shows the optimization potential that lies behind every little detail in the manufacture of precision technology. Whether it be grinding tool costs, which are kept down through long tool service lives or tailor-made solutions to meet customer requests – JUNKER has been making things possible for decades.
