Oxy-fuel Cutting

What Is Oxy-fuel Cutting?

Oxy-fuel cutting (oxygen cutting) is a thermal cutting process in which steel is first heated to ignition temperature and then cut by a high-purity oxygen stream that oxidizes the material. It provides a cost-effective solution particularly for thick plate cutting and is used effectively for thicknesses from 6 mm to 300 mm. At Ankay Büküm in Ankara's Ostim Industrial District, our CNC-controlled oxy-fuel cutting unit and manual oxy-fuel equipment precisely cut low-alloy steel plates. This method is indispensable for projects requiring thick materials such as heavy steel construction, penstock pipes, and shipbuilding.

Application Areas

• Heavy Steel Construction: Cutting beams, columns, and connection plates in thicknesses of 30 mm and above
• Penstock Fabrication: Sizing thick-wall penstock segment plates, flange and stiffener plate cutting
• Shipbuilding and Shipyards: Hull plate cutting, keel plates, and thick-wall structural parts
• Mining Equipment: Bucket plates, wear-resistant Hardox plate cutting, and heavy equipment body parts
• Pressure Vessels and Tanks: Thick-wall pressure vessel body plates, dome sections, and rim flange plates

Technical Capacity and Specifications

Our CNC oxy-fuel cutting unit has a 3000x12000 mm table size. Low-alloy and carbon steel plates from 6 mm to 300 mm are cut. Multi-torch system cuts multiple parts simultaneously for increased efficiency. Cutting accuracy is +/- 1 mm, and surface quality is evaluated per ISO 9013. Cost advantage over plasma cutting is particularly significant above 80 mm thickness. Bevel (weld preparation) cutting is also performed on the same machine.

Quality Assurance

Oxy-fuel cut surface roughness, perpendicularity, and burr condition are inspected per ISO 9013. Appropriate heat input parameters are applied to minimize the heat-affected zone (HAZ) in thick plates. Post-cut dimensional verification and material certificate matching are performed.
