Oxy fuel cutting remains one of the most practical ways to cut thick mild steel plates in India. Fabricators, OEMs, structural contractors and heavy machinery builders depend on it for base plates, flanges, brackets and machine parts that are too thick or too costly to cut by other methods. When combined with CNC control and good fabrication support, oxy fuel cutting delivers accurate parts at a reasonable cost. This guide explains how the process works, when to use it, how it compares with plasma and how it fits into custom fabrication projects.
1. What Is Oxy Fuel Cutting?
Oxy fuel cutting uses a flame of fuel gas and oxygen to preheat steel to its ignition temperature. A jet of pure oxygen is then directed at the hot spot, and the steel reacts with the oxygen and is blown out of the cut. This is why the process is also known as gas cutting or flame cutting. It works on mild steel and low-alloy steels, but not on stainless steel or aluminium.
2. Why Choose an Oxy Fuel Cutting Service?
A professional oxyfuel cutting service gives manufacturers access to CNC machines, trained operators and gas handling without investing in their own setup. Benefits include:
- Ability to cut very thick mild steel plates
- Repeatable accuracy with CNC control
- Lower cost for heavy sections compared with many other processes
- Multiple parts cut efficiently from a single plate through nesting
3. Oxy Fuel Cutting for Thick Plates
Thickness is where oxy fuel cutting really stands out. A gas cutting service for thick plates is commonly used for base plates, counterweights, lifting lugs, gear blanks and heavy machine frames. CNC Laser World lists oxy fuel cutting of mild steel up to 100 mm. For such sections, oxy fuel is often more practical and economical than laser cutting.
4. Flame Cutting Across India
Many industries across the country rely on a dependable flame cutting service India manufacturers can trust, including:
- Construction and pre-engineered buildings
- Earthmoving and mining equipment
- Cranes and material handling
- Agricultural machinery
- Power and infrastructure projects
5. Local Support for Plate Cutting in Indore
For manufacturers in central India, working with a nearby partner saves freight time and makes inspection easier. Oxy fuel plate cutting Indore buyers use allows quick sampling, urgent pickups and easy workshop visits. CNC Laser World has been working in Indore since 2013, runs 17 machines and has completed 2,500+ projects.
6. Profile Cutting as Job Work
Many OEMs and fabricators prefer to outsource. Oxyfuel profile cutting job work lets you send DXF drawings and receive finished profiles without running your own machines. Before starting job work, agree on:
- Material supply and offcut handling
- Tolerances and edge finish requirements
- Sample approval before bulk production
- Delivery schedules for repeat orders
7. Oxy Fuel vs Plasma Cutting
Buyers often compare processes before placing orders. Oxy fuel vs plasma cutting comes down to thickness, material and accuracy needs:
- Oxy fuel cutting suits very thick mild steel and is cost-effective for heavy plates
- Plasma cutting is faster on thinner and medium plates and can cut stainless steel and aluminium
- Laser cutting gives the finest detail on thinner material
Your fabricator can recommend the right process based on your drawing.
8. From Cut Parts to Finished Fabrication
Cutting is usually just the first step. Custom metal fabrication services take cut plates through bending, welding, drilling and assembly to deliver ready-to-use components. Working with one partner for cutting and fabrication reduces handling, transport and coordination errors.
9. Supporting OEM Manufacturers
OEMs need consistent parts, batch after batch. Custom fabrication for OEM manufacturers focuses on repeatable quality, drawing control, scheduled deliveries and clear inspection standards. A long-term supply relationship helps OEMs plan production with confidence.
10. Tips for Better Oxy Fuel Cutting Results
- Share accurate DXF files with material grade and thickness
- Mark critical dimensions and tolerances
- Mention if edges need grinding, bevelling or machining
- Approve a sample before bulk orders
- Plan for straightening on parts where flatness is critical

FAQ
Is oxy fuel cutting the same as gas cutting? Yes. Gas cutting and flame cutting are common names for oxy fuel cutting.
Can oxy fuel cutting cut stainless steel? No. It works on mild steel and low-alloy steels.
When should I choose oxy fuel over plasma? For very thick mild steel plates where heavy sections matter more than fine detail.
Are oxy fuel cut edges smooth? They are rougher than laser edges and may need grinding or machining for some uses.
Can I outsource oxy fuel cutting as job work? Yes. Many manufacturers send drawings and receive cut profiles as job work.
Conclusion
Oxy fuel cutting is a reliable, cost-effective way to cut thick mild steel for heavy industries. When combined with CNC accuracy, good fabrication support and clear communication, it helps manufacturers and OEMs get strong, accurate parts on time. Share clear drawings, choose the right process and work with an experienced partner for the best results.
