Custom Steel Parts

What are the methods of steel machining?

At machined steel parts, we offer a wide range of CNCmachining options to meet your specific needs. Our capabilities include:

CNC Milling

We utilize state-of-the-art CNC milling machines to produce precise and complex steel mill parts / steel mill components. CNC milling allows for the accurate removal of material, creating intricate shapes and features according to your specifications.

CNC Turning

CNC turning is ideal for producing cylindrical steel turned parts. Our CNC turning machines can accurately shape the steel material, creating parts with precise dimensions and surface finishes

Wire Cutting

Our wire cutting capabilities enable us to create custom steel parts with tight tolerances and intricate designs. This process utilizes an electrically charged wire to precisely cut through the steel material, ensuring high precision and excellent surface finish (e.g., galvanized steel parts).


EDM is a precise machining technique used to create intricate shapes in steel parts. It utilizes electrical discharges to erode the material, allowing for the production of complex geometries with high accuracy.

Secondary Manufacturing

In addition to machining, we offer secondary manufacturing processes such as , knurling, drilling, threading, counterbore, countersink, engraving, surface grinding, and others to provide complete solutions for your custom steel parts.

What are the main steel materials in CNC machining?

In our CNC machining, several steels are commonly used due to their excellent machinability, mechanical properties, and availability. As seen the following table for clear information:

Steel Properties Applications
SKD11 SKD11 is a high-carbon steel and high-chromium tool steel. It offers excellent wear resistance, high hardness, and good toughness. SKD11 is commonly used for making cold working tools, such as punches, dies, and cutting tools. It is also suitable for applications requiring high precision and long tool life.
SKD61 SKD61 is a hot work tool steel known for its excellent thermal resistance and high-temperature strength. It contains chromium, molybdenum, and vanadium, which contribute to its exceptional heat resistance and toughness. SKD61 is commonly used for manufacturing die-casting dies, extrusion dies, and hot forging tools,steel forging parts, cast steel parts / steel casting parts, where the material is subjected to high temperatures.
SKH51 SKH51, also known as M2 high-speed steel, is a tungsten-molybdenum high-speed tool steel. It offers excellent hardness, wear resistance, and heat resistance. SKH51 is widely used for cutting tools, such as drills, milling cutters, and taps. Its high-speed cutting capabilities make it suitable for machining applications where high cutting speeds are required.
ASP23 ASP23 is a powder metallurgy high-speed tool steel. It offers high wear resistance, good toughness, and excellent dimensional stability. ASP23 is commonly used in applications where high precision, high wear resistance, and good machinability are required. It is often used for cutting tools, forming tools, and precision components.
ASP30 ASP30 is another powder metallurgy high-speed tool steel. It offers similar properties to ASP23, including high wear resistance and good dimensional stability. ASP30 is suitable for applications requiring high-speed cutting, such as milling, drilling, and turning.
40Cr ASP30 is another powder metallurgy high-speed tool steel. It offers similar properties to ASP23, including high wear resistance and good dimensional stability. 40Cr is often used in applications where higher tensile strength and toughness are required, such as gears, shafts, bolts, and other machine components.
C45 C45 is a medium carbon steel known for its good machinability, toughness, and strength. C45 can be heat treated to achieve different hardness levels and mechanical properties. It is commonly used for manufacturing gears, shafts, and other components of steel structure.

It’s important to note that the specific properties and applications of these steel materials can vary depending on factors such as heat treatment, processing, and specific industry requirements.
