The traditional grinding processes, i.e. internal grinding, face grinding, external circular grinding, and non-circular grinding, are used along with a combined machining process involving hard turning and grinding. Here, all sections that can be manufactured by fail-safe turning processes are hard or soft finish-turned and then finish-ground (i.e. face grinding) in the same workpiece clamping. This mainly occurs after the pre-turning operation if it is required depending on the quality level that is to be achieved. This guarantees higher workpiece quality while reducing cycle times. In addition, the wear of grinding tools is reduced and thus the tools have to be dressed less often.

The X- and Z-axes are separate to achieve maximum accuracy when machining small workpieces. The vertical Z-axis is equipped with a linear drive unit. This allows the grinding spindles to make short, quick oscillating strokes. The X-axis determines the accuracy and is completely removed from the machining area in the vertical arrangement of the internal grinder.

The Internal grinder is characterized by its extremely compact design with no additional units. The energy container and the fluid and electrical components are mounted on the back. The Internal grinder stands out thanks to its accessibility and the ease with which tooling can be carried out.

The offers all modern grinding technologies:

• Grinding tools - e.g. ceramic or galvanized CBN grinding wheels
• Sensor technology - adaptive grinding, initial cut detection, touch dressing
• Dressing technology - dressing spindle for use of diamond form rolls
