ATECH Crater-020-A Pneumatic Clamping Dual Miter Upcut Saw 5.5HP, 45 degree mitering Crater-02 A is a heavy duty automatic upcut miter saw with a 16-1/2″ (420 mm) saw blade. It has 3 main parts; a 420 mm (16-1/2″) carbide tipped saw blade, pneumatic twin horizontal & vertical clamps and air guns. There are also infeed & outfeed tables and pneumatic spray mist lubrication systems among optional equipment. Moreover, Crater-02 A has heavy duty construction for long machine life and hydro-pneumatic saw blade feed. Its movable back fence enables to cut bigger profiles both straight and miter cut. In operation, when the cutting process is finished, the saw blade moves down to its starting position automatically. Crater-02 A has a special safety purpose; for instance, if the top guard is opened during the cutting process, the saw blade moves down automatically. Crater-02 A has also angle adjustments at 15°, 22.5°, 30°, 45°, 90° via a lock pin, and its intermediate angles are adjusted via a mechanical stop. In addition, the rising speed of the saw blade can be adjusted as required (variable speed).
