Steel is a widely-used material in CNC machining due to its excellent mechanical properties, such as high strength and durability. The type of steel employed depends on the specific requirements for each component - strength, hardness, and corrosion resistance included. Stainless steel is a popular choice for CNC machining due to its corrosion resistance and ability to remain strong at high temperatures. Tool steel also makes an excellent CNC cutting material due to its high hardness and wear resistance. Other steel types used in CNC machining include carbon steel, which is cost-effective and easy to machine; and alloy steel which has improved mechanical properties due to the addition of elements like chromium, nickel, and molybdenum. In conclusion, when selecting steel type for CNC machining it's important to take into account your component's requirements as well as any properties needed for final product.

We also have several materials used for CNC machining besides aluminum, steel, plastic, and urethane. Some examples include: Copper and brass: These materials are good conductors of electricity and are often used in electrical applications. Titanium: This metal is strong, corrosion-resistant, and biocompatible, making it ideal for aerospace, automotive, and medical applications. Magnesium: This material has a high strength-to-weight ratio and is commonly used in parts where strength is desired at the expense of weight. Wood: CNC machines can also be used to carve and shape wood, making it a popular material for artistic and decorative projects. Ceramics: These materials are often used in industrial applications due to their high-temperature resistance and durability. Composites: Materials such as carbon fiber composites are used for their strength and lightweight properties in applications ranging from sports equipment to aerospace.

Also referred to as bridge tooling or prototype tooling, is a quick and cost-effective method of performing low-volume injection molding for diverse plastic part types. The creation of an aluminum or steel mold using the rapid tooling technique allows for its integration into the molding process to generate numerous copies of a component. Rapid tooling is employed to produce moldings that fulfill the demands of speedy prototyping within a condensed timeframe or to fill the interim gap prior to high-volume production.
