Voith Launches New MiniGrinder for Tissue Machines

Yankee cylinders with surface irregularities can frequently result in quality deficiencies and production halts in tissue manufacturing.  The MiniGrinder, developed by Voith's OnSite Yankee Service, enables the easy and accurate removal of surface irregularities, old coatings and chatter marks, restoring the Yankee cylinder's ideal crown profile and leading to significant reduction in downtime.

The MiniGrinder’s compact design allows for it to be used on any tissue machine without the need to remove and re-install key machine parts, as is normally the case with conventional grinding machines. This reduction in maintenance time leads to quicker restart time, with one Voith customer even reporting a 14-hour reduction of downtime.

The design and shape of the MiniGrinder has been optimized so that the grinding bed has optimum rigidity. Although the grinding bed is smaller than conventional grinding machines the rigidity is significantly higher. The grinding force of the head is equivalent to that of conventional tangential grinding heads, ensuring maximum precision for all types of applications. The MiniGrinder is suitable for all kinds of metal surfaces.

The exhaust air system used with the MiniGrinder removes the airborne dust that inevitably occurs during the grinding process, reducing the cleaning effort and protecting the health of personnel working on and around the Yankee cylinder.
