As a leading provider of CNC machining services, Great Light understands the importance of providing high-quality precision parts that meet the accuracy standards of various industries. One of the most popular materials used in CNC machining is stainless steel, known for its special strength, corrosion resistance and durability. However, using stainless steel can be challenging and requires dedicated expertise and equipment to achieve the best results. In this article, we will share valuable tips and insights on CNC stainless steel machining to help you make the most of your machining projects.
Understand the characteristics of stainless steel
Before the processing process, it is necessary to understand the characteristics of stainless steel. Stainless steel is a ferrous alloy that contains at least 10.5% chromium content, which provides its characteristic corrosion resistance. The material is available in a wide variety of materials, each grade with its unique characteristics such as 304, 316 and 410. Understanding the specific characteristics of stainless steel grades is essential for choosing the right machining strategy and tools.
Processing technology of stainless steel
CNC machining involves a variety of techniques including milling, turning, drilling and grinding. When using stainless steel, it is crucial to choose the right machining technology to avoid damage, minimize tool wear and ensure accuracy. Here are some tips for processing stainless steel:
- Milling: Use high-speed milling strategies for feed to avoid work strengthening and reduce tool wear.
- Turn around: Select to perform continuous cutting operations at a slower feed rate to prevent overheating and tool wear.
- drilling: Use pilot holes and slow feed rates to avoid damage to the material and ensure accurate hole position.
Tool selection and maintenance
When processing stainless steel, the right tool selection is crucial. The following tips will help you choose the best tool for your project:
- Cutting tools: Use high-speed steel (HSS) or tungsten carbide (TC) cutting tools because they offer excellent wear resistance and durability.
- coating: Apply coatings such as titanium nitrate (TIN) or alumina (AL2O3) to reduce tool wear and improve surface finish.
- Tool maintenance: Check and maintain your tools regularly to prevent damage and ensure optimal performance.
Optimize CNC machining parameters
Using stainless steel, CNC machining parameters play an important role in achieving optimal results. The following tips will help you optimize processing parameters:
- speed: Use slower speed to avoid overheating and reduce tool wear.
- Feed rate: Adjust the feed rate according to processing technology and tool selection.
- Coolant: Use coolant to reduce heat generation and prevent tool wear.
Post-processing and completion
After processing, the necessary post-treatment and completion techniques must be applied to achieve the required surface finishes and characteristics. Some common after-treatment techniques for stainless steel include:
- Grinding: Use grinding operations to achieve high surface finish and remove any machining marks.
- polishing: Apply polishing operations to achieve mirror-like finish.
- Passivation: Perform passivation treatment to remove any free iron and restore the corrosion resistance of the material.
