SR8-2 is designed for one-sided surface planing of flat hardwood
or softwood work pieces to their specified thickness with mechanical feeding.
- Cutter shaft driven
either by electric motor or by using the V-belt drive.
- Feeding mechanism
with individual electric motor chain drive to 2 upper and 2 lower feeding rolls.
- Upper front roll is ribbed while the rear one is plain (the front roll in
SR8-2 is selective; it allows for handling of several work pieces with a difference
in thickness of up to 4 mm).
- Feed rates 8 and 16 m/min are provided
by a double-speed electric motor that is equipped with a toggle switch.
The box-shaped bed plate is made of cast iron and has a handwheel-driven manual
movement mechanism, a mechanical movement mechanism driven by electric motor and
a bed plate lock mechanism. The guides and two plain feeding rolls are mounted
on the bed plate. The rolls have an adjustable height so as to eliminate the edge-clipping
- A grapple shield preventing ejection of the work piece is installed
in front of the feeding rolls.
- Pinch elements ensure high-quality timber
- To avoid timber split in the place where the blade exits,
a front clamp is installed to support the fiber (the clamp is made a several sections,
each one spring-loaded).
- The bar-shaped rear clamp can swing around
its horizontal axis. It is designed for removing chips off the surface and forcing
them towards the sucker zone.
