These vertical milling machine guards are ideally suited to the size of machine normally found in school workshops. There are two sizes each consisting of nylon coated steel members carrying polycarbonate extension visors which can be adjusted in the vertical and horizontal planes to clear protruding vices, jigs or fixtures. The parts can be arranged to form a 3-sided box or an extended line across the front of the table. Special release devices allow rapid access to the work piece or cutter. The guards are clamped to the table using special Tee Nuts, therefore the size of the Tee Slot on your machine must be specified when ordering.
