| Tolerances | Wall Thickness | Max Part Size | Lead Time |
|---|---|---|---|
| The achievable machining tolerances depend on the specific type of steel being used, but typically a tolerance of 0.005 inches can be achieved. | It is possible to achieve a minimum wall thickness of 0.03 inches (0.8mm), although this may vary based on the ratio of wall thickness to planar dimension as well as the specific type of steel being used. | The maximum part size that can be realized is 2000 x 800 x 1000 mm. | The minimum lead time for commonly used steel is 5 days, but this may vary depending on the specific type of steel and whether the parts are being manufactured internationally. |
About The Material
Steel is a metal alloy made up mainly of iron and carbon, with small amounts of other elements such as manganese, silicon, sulfur, and phosphorus. The carbon content in steel typically ranges between 0.2% and 2.1% by weight, with higher carbon content resulting in a harder and stronger metal.
Steel is one of the most widely used materials in construction, transportation, and manufacturing due to its strength, durability, and versatility. It is used to make a wide range of products, from cars and ships to buildings and infrastructure.

CNC Machined Steel Applications
CNC-machined steel parts are highly versatile and find applications in a wide range of industries, including aerospace, automotive, medical, and defense. The precision and accuracy of CNC machining processes allow for the production of intricate and complex steel parts with tight tolerances, which are critical for many applications.
Surface Finishes For CNC Machined Steel Parts
AT-Machining can provide the perfect finishing touch to your CNC machined Steel parts with a range of powder coating, bead blasting, and plating options. Each finish offers its own advantages – so make sure you select the one that meets all your requirements!
Nitriding
Steel nitriding is a process of surface hardening for steel materials by diffusing nitrogen into the surface, resulting in improved wear resistance, fatigue strength, and corrosion resistance.
Black Oxide
Black oxide on steel involves a chemical conversion process that creates a dark, uniform, and corrosion-resistant layer on the surface of the steel.
Carburizing
Carburizing on steel involves a heat treatment process that introduces carbon into the surface of the steel, resulting in a harder and more wear-resistant outer layer.
Bead Blasted
Bead blasting on steel involves shooting fine glass beads or metal pellets at high pressure onto the surface of the steel, resulting in a uniform matte finish with improved corrosion resistance.
Powder Coat
Powder coating on steel involves applying a dry powder electrostatically to the surface of the steel and then curing it with heat, resulting in a durable, uniform, and attractive finish that is resistant to chipping, scratching, and fading.
Plating
Process of applying a thin layer of metal onto the surface of the steel to improve its appearance, protect it from corrosion and wear, and enhance its conductivity or other properties.

CNC Machining Steel FAQs
CNC machining steel offers several advantages, including high strength, durability, and versatility.
Steel is a commonly used material in many industries due to its excellent mechanical properties, which makes it ideal for many applications. CNC machining allows for the precise and accurate shaping of steel parts, making it a reliable and efficient manufacturing process.
CNC machining offers precise, efficient, and versatile steel part production, making it a popular choice for industries such as aerospace and medical.
It enables tight tolerances and repeatable cuts, producing highly precise manufacturing.
With the ability to run continuously and produce identical parts, CNC machining is fast and efficient, especially for large production runs. It can produce steel parts in various sizes, shapes, and complexities, including complex geometries and tight tolerances that are difficult or impossible to achieve with traditional machining methods.
Consistent quality and accuracy in every part produced minimize the risk of errors and scrap, resulting in increased production yields and cost savings for both large and small runs.
Complexity: Parts with complex geometries or tight tolerances require more time and effort to program and machine, which can increase costs.
Quantity: The cost per part decreases with higher production runs due to economies of scale, while smaller runs may have a higher per-part cost.
Finishing: Additional finishing processes such as polishing or painting can increase the cost of CNC machining.
Design changes: Design changes during the production process can add to the cost, as it may require additional programming or machining time.
Machine capabilities: The type and capabilities of the CNC machine used can also impact the cost of machining, with more advanced machines typically costing more to operate.
The maximum size of CNC machined steel parts is determined by the size of the CNC machine being used. However, most CNC machines have a maximum workpiece size of around 40 inches (1016mm) by 20 (508mm) inches by 20 inches (508mm).
