7. Gate Cutting Oxygen and GLP . Capacity: Small-scale Parts For carbon steel,chromium molybdenum,and chromium-nickel molybdenum parts.

8. 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.

9. 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 .

10. Gate Cutting Gate Cutting by Breaking The feeder is choked to assist the break on impact.

11. Gate Cutting Universal Cut-Off Machine Diameter of cutting disc : 800 mm. Peripheral speed: 100 m/seg. Maximum diameter cut: 200 mm.

12. Scarfing with graphite electrode. To remove metal left by the cutting . Aim: To reduce grinding time and save the grinding wheel. Scarfing

13. Scarfing Part after cutting Part after scarfing
