cross-cutting
operation of cutting across the grain of a wooden workpiece
3.3.2
double mitre sawing machine for V-cutting
machine designed to make special cross-cuts for e.g. picture frames, furniture, doors or furnishings. The
machine is fitted with one saw unit or two saw units (dual stroke machine). The saw unit consists of one or two
saw blades whose spindles are situated above (vertical double mitre sawing machine for V-cutting, see
Figure 1) or behind the workpiece (horizontal double mitre sawing machine for V-cutting, see Figure 2) when
the saw blades are in their rest positions. The angle between the saw spindle axes can be either fixed
(normally 45°) or adjustable from 0° to 45° with respect to the centre line of the machine. The saw blades
move into or through the workpiece in vertical or horizontal direction during the cut to produce a V-cut in one
cycle. The feed of the saw unit can be manual or integrated feed
