What is steel machining?
Steel machining is the process of using CNC machines to shape and size steel materials. The manufacturing process includes milling, CNC turning and grinding. Steel CNC machining plays a critical role in industries ranging from automotive to aerospace, construction, etc.
Why CNC machining steel?
Steel is the most common material in the CNC machining process. Because of its exceptional strength, durability, and properties, it is suitable for a wide range of applications. However, these same properties also make steel challenging to machining. High hardness, toughness, and thermal conductivity require careful consideration when selecting cutting tools, speeds, and feeds.
What Steel is Commonly Used for Machining?
There are many types of steel, and the different steel you’re machining will significantly impact your approach. Here are some common types for CNC machining process:
Carbon steel
Carbon steel is the most popular machining material because of its low price and machinability. Its hardness, strength, and resistance to deformation make it suitable for large-volume production. According to the carbon content, we divide it into low-carbon steel (#20), medium-carbon steel (#1045), and high-carbon steel.
Alloy steels
Alloy steel (such as 4140 or 4340) contains additional alloy elements, such as chromium, nickel, or molybdenum, to improve the hardness, toughness, and corrosion resistance of steel. Therefore, they are applied in manufacturing higher-performance mechanical parts like gears and shafts.
Stainless steel (SUS304, #304 0Cr18Ni9)
Stainless steel is known for its good corrosion resistance, so it’s widely used in precision machining such as instruments and the chemical industry.
Tool Steel (such as H13, D2)
Tool steels are designed for cutting and shaping other materials. They are extremely hard and wear-resistant, typically used for injection molds or dies.
Cast Iron (HT150 Grey cast iron)
Cast iron has good cutting performance, the hardness is low, but good wear resistance. So it’s suitable for processing small quantities of complex parts or friction parts.

Best Practices for Steel Machining
To achieve high-quality results, AMSL keeps following the following practices:
Choose the right tooling
Select cutting tools with appropriate geometry and coatings for different types of steel machining.
Optimize cutting parameters
According to the steel’s properties and performance, adjust the spindle speed, feed rate, and cutting depth of the steel.
Strategically of coolant
Coolant not only reduces heat but also improves surface finish and tool life. However, excessive coolant can lead to thermal shock.
Maintain rigidity
Make sure the workpiece are secured well during machining process.
Monitoring tool wear
Regularly inspect or replace tools for signs of wear, such as chipping or dull edges.
Quality Guarantee
Randomly inspect steel parts or components; make sure parts comply with the requirements and meet the tolerance.
