Gate Cutting

Iron Dust and GLP• Capacity: Cutting small

and large parts . • For parts with chromium

elements above 5% and inoxidable steel

• GLP – for large-scale parts.

Gate Cutting

Disc Gate Cutting

• Recommended for small and large parts, making a groove in the area of the cut,followed by a break on impact.

Gate Cutting

Gate Cutting by Breaking

• The feeder is choked to assist the break on impact.

Gate Cutting

Universal Cut-Off Machine

• Diameter of cutting disc : 800 mm.

• Peripheral speed: 100 m/seg.

• Maximum diameter cut: 200 mm.

Scarfing with graphite electrode.

• To remove metal left by the cutting .

• Aim: To reduce grinding time and save the grinding wheel.
