Stainless Steel Milling

Trace-A-Matic specializes in CNC milling stainless steel parts and assemblies using state-of-the-art CNC mills, 5-axis machining centers, and high-speed cutting tools. Years of experience provide expert knowledge of cutting a wide range of stainless steel alloys, their characteristics, and how the stainless steel material group reacts when machined. Tool selection, cutting pass depths, mill/lathe feed and speed, chip control, and high-pressure coolant are critical in controlling heat generation, which can cause part movement and tool deflection during the machining process. This skill level ensures world-class precision machining that meets or exceeds the most demanding tolerances. The innovative Trace-A-Matic team is always available to review your machining parts and guide you during the design process. Our goal is 100% customer satisfaction, providing AS 9100/ISO 9001:2015 certified quality machining resulting in timely turnaround and on-time delivery.

Stainless Steel Milling
Stainless Steel Characteristics:
  • High strength to weight ratio
  • Excellent corrosion resistance - austenitic and duplex grade
  • Ferritic stainless steels contain chromium with low carbon content
  • Austenitic stainless steel adds nickel and represents 70% of production - 304 and 316 stainless being the most common
  • Martensitic holds a high carbon content and is heat treatable
  • Duplex grade adds molybdenum to a combined ferritic and austenitic construction
  • Precipitation hardened stainless combines austenitic and martensitic grade qualities and is heat treatable

In stainless steel milling, the cutting edge of the milling tool plays a critical role in achieving precise and efficient material removal. Machining stainless steel requires specialized techniques due to its inherent hardness and toughness. The cutting edge of the milling tool must withstand the abrasive nature of stainless steel while maintaining sharpness and durability throughout the milling process. High-speed steel (HSS) and carbide cutting tools are commonly used for stainless steel, offering distinct performance and tool life advantages. Additionally, advanced coatings such as titanium nitride (TiN) or diamond-like carbon (DLC) can enhance cutting-edge wear resistance and prolong tool life in SS milling applications. With proper tool selection and machining parameters, SS milling can yield precise, high-quality parts for various industrial applications.
