Stainless Steel Processing Solutions
OMC solutions for stainless steel processing are designed to handle a demanding material — delivering clean cuts, dimensional stability and consistent tool life even on AISI 304 and 316 alloys.Stainless steel requires a very different approach compared to aluminum and PVC: reduced cutting speeds, carbide tools with specific geometries and coatings, adequate coolant lubrication, and particularly rigid machine structures to contain vibrations. OMC machines handle these variables with controlled hydraulic feed, high-clamping systems and cutting parameters adjustable to suit the alloy type.
Stainless steel processing challenges
Hardness and work hardening
Stainless steel — particularly austenitic alloys such as AISI 304 and AISI 316 — tends to work harden under tool action: if the blade works with insufficient feed or stops on the material, the surface hardens locally and the next pass becomes even harder. OMC machines use hydraulic feed with controlled and constant speed to prevent this phenomenon.
Cutting temperature and coolant lubrication
Stainless steel generates more heat than aluminum during cutting. Without adequate lubrication, the blade overheats quickly, losing cutting capacity. OMC cutting machines and machining centers are equipped with adjustable mist lubrication systems that keep the tool and material temperature within optimal limits.
Rigidity and vibrations
Cutting stainless steel requires a more rigid machine structure than aluminum, because vibrations result in surface imperfections and accelerated tool wear. OMC machines are built with heavy structures and reinforced frames precisely to work stiff materials like stainless steel.
Choosing the right machine for stainless steel
Alloy type
Ferritic alloys (AISI 430) are easier to machine, while austenitic alloys (AISI 304, 316) require specific tools and reduced cutting parameters. Duplex and high-strength stainless steels require particularly rigid machines with hydraulic feed and continuous lubrication.
Profile section and thickness
The Raptor 3000 is the only OMC machining center designed to also work stainless steel up to 3 mm thickness: the 5 HP electrospindle, ISO 30 tool holders and enclosed structure ensure the rigidity needed for these materials.
Recommended stainless steel machinery
Cutting
Double head cutting machines and single head cutting machines from OMC can be equipped with carbide blades specific for stainless steel, with reduced tooth geometry and cutting angle to minimize heat generation and work hardening. Adjustable hydraulic feed is essential to maintain constant speed.
CNC milling and drilling
The Raptor 3000 works stainless steel profiles up to 3 mm with its 5 HP electrospindle at 12,000 RPM. CAD/CAM programming on Windows PC allows managing complex operations on multiple sides with automatic tool changes.
Why process stainless steel with OMC machines
Cutting precision and repeatability even on the most demanding alloys, thanks to hydraulic feed and brushless motors. Greater tool life due to the machine's structural stability and correct speed and lubrication management. Waste reduction and improved product quality through CNC process control. Dedicated technical support and 24/7 parts availability.
