ATI CUT-350Y is a metallographic semi-automatic cutting machine which adopts fully closed structure, with good sealing effect, safety and reliability. Electrical appliances such as motors are separated and isolated from the cutting area, so the equipment is safer and the electrical appliances have a longer life. The sturdy chuck and cutting blade can easily cut downwards with much pre- cision. The front handwheel can control the back and forth movement of the worktable with stable power, while the rear mo- tor can automatically control the back and forth movement of the worktable with constant force. The workpieces to be cut can be fixed at different heights and in different front and rear positions of the workpiece, and the combination of different positions can complete large cuts. The upper part of the equipment is completely covered by an openable and resealable protective cover. The large observation window on the protective cover is illuminated by a clear, high-brightness LED lamp. The operator can control the cutting process of this metallographic cutter at any time. The cutter adopts quick clamping device, which can clamp objects more quickly and accurately. The grooved worktable is matched with the quick clamping device to satisfy the cutting of various special shape workpieces. The super powerful cooling system prevents the workpiece from burning while cutting. The cooling water tank is located in the base of the equipment, in the water tank there is a filter element to facilitate the collection of residues and scraps.
