CNC stainless steel cutting is one of the widely used processes to manufacture parts for several industries. This process provides precise components for the equipment that cannot be provided by traditional manufacturing methods. This CNC stainless steel cutting guide provides a detailed overview of the CNC stainless steel cutting process, its types, major methods to fabricate parts, and the challenges of using it in industry.
What Is CNC Stainless Steel Cutting
CNC Stainless Steel cutting is the process that uses computer numerical control machines to cut raw SS into fabricated parts with very high accuracy. A CNC machine follows a program or code to operate cutting tools to produce highly precise parts as per the customer’s needs for their applications.
Normally, stainless steel is a material with good strength and corrosion resistance characteristics. It has a very good aesthetic appeal compared to the other metals, making it more convenient to use in architectural applications. However, the hardening characteristics of SS make it more difficult to perform cutting processes.
The CNC cutting process generally needs digital files called CAD drawings of the parts and their requirements, which are converted into machine-readable codes. Machine-readable codes control the overall cutting process used to fabricate the desired parts. This CNC stainless steel cutting process provides an accurate, smooth finish on the parts, which also reduces the cutting time and material waste from raw stainless steel.
Main CNC Cutting Methods
Several types of CNC cutting methods are used for various grades of stainless steel materials. The cutting methods normally depend on the stainless-steel thickness and its mechanical and thermal properties. It also depends on the application where the CNC SS is used. The most common CNC cutting methods for stainless steel are given below:
Laser cutting
Laser cutting is one of the most popular CNC cutting processes for stainless steel materials. The laser cutting process uses a high-power laser beam to melt or vaporize stainless steel along the required path and fabricate stainless steel parts for the applications.
This method is most suitable for medium-thickness stainless steel, as it provides precise and accurate surface finishes on the parts. This process ensures the structural integrity of the parts by producing the least effective heat zone in the materials. This process is commonly used in medical, electronic, and decorative work where precision and smoothness are important.
The following are the benefits of using laser cutting for stainless steel:
- It fabricates the parts with high precision and tight tolerance
- It provides a smooth surface finish on parts and also has a minimal secondary process for the fabricated parts.
- It is more suitable and faster for thin SS materials.
Plasma cutting
Plasma cutting is a highly advanced cutting method for making stainless steel parts. This process is performed by CNC machines, which use a high-velocity jet of ionized gas, called plasma, for cutting. This method is used for heavy-duty applications because it provides faster cutting speeds and is also cost-effective compared to laser cutting. This process is mostly used in shipbuilding, heavy machinery, and construction, where stainless steel is a good choice due to its corrosion resistance and high strength characteristics.
The following are the benefits of using plasma cutting for stainless steel:
- It cuts the medium to thick grades of stainless steel.
- It is faster to cut the heavy materials than with laser cutting.
- This process has a lower operational cost than other cutting processes.
Waterjet cutting
Waterjet cutting is another type of cutting process for stainless steel that uses high-pressure streams of water with a mixture of abrasive particles. This method is popular because it does not generate heat during the cutting process of the SS. Heat management during the process is not required in this method. The waterjet cutting process can handle a wide range of thicknesses while maintaining the materials’ properties. This cutting process is mostly used to fabricate the parts for aerospace, medical, and precision engineering applications.
The main advantages of using the waterjet cutting process for CNC stainless steel are given below:
- There is no risk of the material distorting using the waterjet cutting process, which keeps the original properties of the materials after the fabrication.
- It provides high precision and clear edges on the fabricated parts.
- This process is suitable for the thick and delicate materials that are referred to as critical parts for the aerospace and medical industries.
