The FLADDER® HYBRID is designed for grinding workpieces that require calibration grinding on the surface and rounding of edges.
Workpieces are advanced on a common conveyor belt through the two grinding processes.
Grinding workpiece surfaces
In order to achieve optimum cycle times for the two very different grinding processes and avoid unintended heating of the workpiece, the calibration grinding is carried out by a transverse grinding belt which is briefly brought into contact with the workpiece surface by reciprocating contact wheels.
The short contact time with the workpiece ensures the workpieces from inappropriate heating and ensures optimal utilization of the sanding belt. The workpieces can then be presented to the conveyor belt at a pace which is solely determined by the extent of the subsequent edge rounding.
In order to produce true uniform radi on all edges, it is a prerequisite to use radial flexible grinding cylinders, the structure and density of which must be selected based on the task at hand.
Depending on the desired process time and the amount of edge rounding, it is important to be able to freely choose the spindle RPM in the range of 300-2000 RPM, which is possible with the well-known oscillated FLADDER 300/gearhead.
