CNC Plasma cutting stainless steel is a fast and cost-effective cutting process for medium to thick stainless steel metal parts in the manufacturing process. This process is performed by a computer-controlled system with very high accuracy.
The custom thick metal parts are fabricated using this process, which offers large-scale production for customers. This process provides durable parts for the industries. However, heat management is crucial to achieve smoothness and maintain the original properties of the raw stainless steel.
What Is Plasma Cutting
CNC plasma cutting is a computer-controlled metal cutting process where a jet of ionized gas called plasma is used to fabricate the required shape of stainless-steel parts. The CNC machine controls the plasma torch along the specific cutting path as per the design of the stainless-steel parts to cut the raw workpiece. Materials along the cutting path are blown away by the force of the gas stream and obtain the required shape.
The CNC plasma cutting process works by sending an electrical arc through gas, including oxygen or nitrogen, which turns it into plasma with a very high temperature. The high-temperature plasma is enough to cut stainless steel. This process is basically used to cut very thick stainless-steel plates for simple shapes.
Advantages and Limitations
CNC plasma cutting has several advantages in fabricating heavy-duty stainless-steel parts. The major advantages of CNC plasma cutting stainless steel are given below:
- It has a fast-cutting speed for medium to thick stainless-steel sheets
- The initial and operational cost of the CNC plasma cutting machine is lower than that of other types of CNC cutting processes.
- It provides accurate cutting for thicker sheets
- It has the ability to cut the conductive metal in an effective way
- It is a reliable process to control and fabricate the custom parts on a large scale
Even with several advantages, plasma cutting has some limitations, such as a rough surface finish, extra chip formation, and the need for extra cleaning. The major limitations of the CNC plasma cutting of stainless steel are given below:
- It is less precise than lasers and other types of cutting methods for detailed designs
- It has a wider cut width that can reduce the accuracy on small stainless-steel parts
- The plasma distorts the thinner stainless-steel parts
- This process needs extra cleaning of slag or dross due to the plasma
Plasma vs Laser
CNC plasma and laser cutting are widely used cutting processes for stainless steel parts. Both cutting methods have their own advantages and disadvantages, which depend on the applications.
CNC laser cutting is normally used for thinner sheets to get precise and accurate finishing on stainless steel parts. The laser cutting process is used for tight tolerance and smooth surface finishing. It can be used to make complex shapes of stainless steel parts for the medical and aerospace industries, where precision is most important.
CNC Plasma cutting is generally used for medium to thicker stainless-steel sheets to get accurate dimensions. This is used for larger and repetitive production of stainless steel parts at a higher speed. The parts that do not need a very fine surface finish are fabricated using CNC plasma cutting. The heavy-duty stainless-steel parts are fabricated through this process for structural supports. CNC plasma cutting is also chosen for its cost-effectiveness compared to the laser cutting process. CNC plasma cutting is used to fabricate large brackets, supporting frames for construction, and heavy-duty machinery.
Best Use Cases
CNC plasma cutting stainless steel is used to fabricate parts for industries, where it provides strong, durable stainless steel parts with faster speeds. CNC plasma cutting is best for customers or industries in the following cases:
- The larger brackets, frames, and plates for construction use
- Heavy machinery frames and parts
- Metal plates for shipbuilding
- Parts required for the automobile repair and structural steel fabrication
- Other industrial parts production
In addition, CNC plasma cutting processes are used for large production volumes of industrial and custom parts. This process provides reliable, cost-effective stainless-steel parts.
Safety and Fume Control in CNC Plasma Cutting
Safety is an important consideration in thermal cutting processes, such as laser and plasma CNC cutting. The generation of heat, sparks, and fumes during the CNC plasma cutting process heavily affects workers’ health and life. Proper safety guidelines, equipment, and fume containment systems reduce the risk of injury. This also ensures safer working environments for the workers.
The following are things to do that protect the workers from the fumes and create a safer working environment during the plasma cutting process in factories:
- The use of protective gear, such as gloves, googles, face shields, and thermal protective aprons, helps reduce the risk of injury.
- No flammable materials inside the working area helps to reduce the risk of fire.
- The installation of proper ventilation helps to move the fumes from the working area.
- Giving safety training to the workers about the use of the CNC plasma cutter also reduces accidents.
The use of the above-mentioned process significantly improved safety and fume control during CNC Plasma cutting during the manufacturing of stainless-steel parts. The standard safety practices protect workers’ lives and smooth the entire CNC plasma cutting process.
