The top roller is held in a chuck head and is being pressed against the drive roller. This permits to grind untrue or pre-ground cots with an extraordinary high rotary accuracy.

Custom built, especially hardened chuck heads are avail-able for all commonly used top rollers.

The attachment is distinguished by its user friendliness and is assembled in a few moves.

The very solid and durable design permits the processing of larger quantities of top rollers in shift work and is of ex-tremely low maintenance.

Thanks to the revisions made the range of application has been enlarged and is compatible with existing chuck heads of previous models.

Grinding range:

• Grinding between centres

Max. distance between centres 650 mmMax. grinding length 600 mmMax. cot diameter 140 mm

• Grinding with top roller attachment

Min. Ø of cots 19 mmMax. Ø of cots 65 mmMax. Length of top rollers 200 mm
