To increase productivity, all portal type grinding centres can be equipped with two rotary tables, if requested in differing designs.
For all grinding centres in portal design, a wear-less direct drive in the X- and Y-axis is available, providing excellent machining and measuring accuracy.
Various tool changing systems are available for all product lines.
Today, complete work piece machining has become an important feature.
The following operations can be machined in only one set-up:
- All machining applications of the Ri grinding centres
- Horizontal machining
- Grinding of guide ways
- 3-axis jig grinding
- Flat grinding in oscillating movement
- Machining of special materials, for example special types of class or ceramics
With the optionally integrated measuring unit, all diameters and faces can be measured automatically. In noncircular and jig grinding applications, this measuring unit can also be used for work Piece localisation.
In general, all grinding centres in portal design are built according to customer‘s requirements. Other than the new RP 8 model, for which a standard is defined.
