What is steel milling? 

 Milling is a machining method in which rotating cutting tools remove material to create high-precision parts. Steel is one of the most widely used materials in industry, but its hardness and variations in alloy place high demands on the milling method. 

We work with: 

  • Black plate, extra high strength steel, wear plate and heavy plate 
  • Raw materials such as steel round bars, flat steel, square bars and stainless steel 
  • Customized processing methods for each steel type 

Challenges in steel milling and how we solve them

Hardness and wear resistanceSteel can be challenging to machine due to its high hardness. We use advanced cutting tools and custom cutting parameters to optimize tool life and surface finish. 

Chip removal and cooling: Effective cooling is essential when milling steel to prevent premature tool wear. We use high-pressure cooling and optimized cutting angles to ensure stable production. 

Precision and tolerances: In CNC milling, we work with tight tolerances and advanced measurement technology to ensure high repeatability and quality. 

Useful tips for machinists when milling steel 

 To achieve the best possible results when milling steel, it is important to use the right technique and tooling strategy. Here are some concrete tips: 

  • Choose the right cutting data: When milling high-strength steel, the cutting speed should be between 80-120 m/min, while stainless steel usually requires 50-90 m/min depending on the alloy. 
  • Customize the feed: For roughing, the feed can be set to 0.1-0.3 mm/tooth, while finishing often requires 0.05-0.1 mm/tooth for the best surface finish. 
  • Use tools with a coating: PVD coated cutting tools are ideal for wear-resistant steels and significantly improve tool life. For stainless steel, TiAlN coatings can provide better heat resistance. 
  • Optimize the cutting depth: For maximum efficiency in roughing, the depth of cut should be 2-5 mm, while finishing is often between 0.2-1 mm. 
  • Stable clamping: Ensure that the workpiece is properly clamped with as short a projection as possible to minimize vibration and improve accuracy.
