What Is A Steel-Cnc Parts

Understanding What Is A Steel: Composition and Material Strength
When asking What Is A Steel, we are referring to one of the most essential structural materials in modern manufacturing. Steel is primarily an alloy of iron and carbon, with carbon content ranging between 0.05% and 1.5%. While this may seem like a minor variation, it results in significantly different mechanical properties.

Mocayo engineers emphasize three key metrics when selecting steel for CNC parts:

• Hardness (measured in HRC)

• Toughness (impact energy value)

• Corrosion resistance (PREN value for stainless steels)

In CNC parts manufacturing, steel can be categorized into three major types:

• Carbon Steel – cost-effective and ideal for structural components

• Alloy Steel – includes Cr, Mo, and other elements for enhanced performance

• Stainless Steel – contains over 12% Cr, forming a self-healing protective film

At Mocayo, our extensive CNC experience reveals that different steel grades present distinct machining behaviors.

CNC Parts Manufacturing: Precision Meets Efficiency
CNC (Computer Numerical Control) machining transforms raw steel into high-precision CNC parts through automated programming and multi-axis motion control. A typical CNC machining process includes CAD design → CAM programming → machine setup → precision machining → quality inspection.

For efficient steel machining, tool selection is critical. Mocayo recommends:

• Carbide tools – for general steel parts

• CBN tools – ideal for hardened steel

• Ceramic tools – suitable for high-speed cutting

For example, machining 45# carbon steel typically involves:

• Cutting speed: 120–180 m/min

• Feed rate: 0.1–0.3 mm/rev

• Depth of cut: 2–5 mm for roughing, 0.1–0.5 mm for finishing

We adhere to ISO 2768 medium tolerance standards, with key dimensions controlled within ±0.01 mm and surface roughness down to Ra 0.8 μm.
