The saw blades can be mounted on one or more saw spindle(s) which may be capable of vertical adjustment. The saw blades may be capable of axial adjustment either relative to the spindle or together with the spindle. The saw blade spindle(s) may be arranged so that they are: a) all mounted above the workpiece support; b) all mounted below the workpiece support; c) mounted both above and below the workpiece support. The cutting mode can be ‘against the feed’ or ‘climb cutting’ or a combination of both (see Figure 1).
