Kehren ri grinding machine 

Vertical grinding centres: Ri
Ri machines are used everywhere complex machining tasks must be performed with maximum precision and economy in mind. These machine types are generally used in mechanical engineering, tool machine construction, turbine and engine construction, bearing manufacturers, transmission manufacturers, contract manufacturers as well as in the glass industry. To increase profitability, we also offer this type of machine as a double version.

For all Ri grinding centres, a wear-less direct drive in the X-axis is available, providing excellent machining and measuring accuracy. The product lines Ri 6 to Ri 12 can be equipped with an optional Y-axis as side support for horizontal machining.
All product lines can be delivered in standard or in grindturn design. The grindturn design includes a turning tool adapter instead of a grinding spindle. The machine can also be equipped with a chip conveyor.
Various tool changing systems are available for all product lines.

Today, complete workpiece machining has become an important feature. The following operations can be machined in only one set-up:
- Faces
- Internal and external diameters
- Internal and external tapers
- Radii
- Noncircular and jig grinding
- Gearings (Hirth/curvic)
- Hard turning (Fine machining)
- Hard milling (Fine machining)
- Boring (Fine machining)
All diameters and faces can be measured automatically by an optionally integrated measuring unit. For noncircular and jig grinding, this measuring unit can also be used for the localization of a workpiece.
