In principle, the finishing and denibbing of windows is a difficult and often subjective task. If your main focus is on surfaces and radii, then you can get first-class sanding results with a throughfeed machine such as the DiscMaster, especially for woodsanding. If, however, you need to sand deeper profiles and rebates, then the sanding unit must move along the profile, similar to “single piece” processing.And this is exactly what the WindowMaster FA6D is designed to do.
The sash is pinned to the table pneumatically. The processing unit runs on a linear guide along one side and automatically processes the top and bottom surfaces as well as all profiles and rebates outside and inside. The processing unit identifies the length of the workpiece and processes the next side of the frame on its return journey.
Two discs with relatively short sanding strips process the surfaces on the top and bottom. Four rollers with longer sanding strips process the profiles and rebates on the inside and outside. Georgian bars, cross-bars and the workpiece length are recognized automatically.
