CNC Machining with Steel Explained

Learn all about your options for stainless and tool steel in your CNC machining projects.

One aspect that defines CNC machining’s excellence is its ability to work with many materials.

Steel stands tall among them. Known for its unparalleled strength, durability, and adaptability, industries ranging from automotive to construction vouch for CNC-machined steel components.

Dive into the many advantages of machining steel, explore the popular alloys, and learn about the challenges for your next manufacturing project.

Why Opt for CNC Machined Steel Components

Steel’s dominance across industries isn’t just by accident. Its properties make it an attractive choice for CNC machining:

Strength and Durability: Steel’s innate tensile strength makes it an ideal candidate for components requiring longevity and resistance to wear and tear.

Heat Resistance: Steel can withstand higher temperatures than many other metals, making it suitable for applications exposed to intense heat.

Versatility in Finishing: Steel’s surface can be quickly finished to achieve desired aesthetics or enhanced resistance.

Machining Precision: Steel’s rigid nature allows for high precision during machining, ensuring parts are produced to exact specifications.

Cost Efficiency: Given its widespread availability and durability, steel often presents an economical solution for both one-off projects and mass production. While not as inexpensive as aluminum, the higher cost can be balanced with higher performance.

Critical Steel Alloys for CNC Machining

Different projects necessitate different steel alloys. Each alloy brings its unique set of properties to the table. Here are some of the most commonly machined steel materials on the MakerVerse platform:

Stainless Steel 304 is widely recognized for its excellent corrosion resistance and formability. It is often used for kitchen equipment, architectural paneling, and piping.

Stainless Steel 316L is known for even more excellent corrosion resistance, especially against chlorides. It’s a favorite for marine applications, chemical processing, and medical implants.

Stainless Steel 17-4PH: It is renowned for its high strength, hardness, and good corrosion resistance. It’s a go-to for applications requiring high strength and a modest level of corrosion resistance.

Tool Steel: Exceptionally durable and resistant to abrasion, making it the ideal choice for tooling applications, dies, and cutting operations.

Choosing the suitable steel alloy is pivotal to the success of your project. With MakerVerse’s experienced team, we can always ensure optimal material selection.

Addressing Challenges in CNC Machining Steel 

While steel is handy, certain intricacies must be considered. Fortunately, MakerVerse’s supply chain is thoroughly vetted to avoid these challenges.

Managing Heat Generation: Steel machining can generate substantial heat. Adequate cooling mechanisms and coolants are vital to prevent part deformations.

Tool Wear: Steel’s hardness can lead to accelerated tool wear. Using tungsten carbide tools or tools with suitable coatings can mitigate this.

Ensuring Surface Finish: Since steel can be prone to oxidation, post-machining processes may be necessary to ensure a smooth, rust-free surface.
