Stainless steel CNC machining characteristics and selection of milling cutters｜Ruipang optimizes machining skills to improve efficiency

Stainless steel CNC processing is a common metal processing method, but due to the high hardness and corrosion resistance of stainless steel materials, higher requirements are put forward for processing equipment and tools. This article will introduce the characteristics of stainless steel CNC machining and provide you with suggestions on choosing the right milling cutter.

1. Characteristics of stainless steel CNC processing

High hardness: Stainless steel usually has a higher hardness, so it requires high wear resistance of cutting tools.

High Toughness: Stainless steel materials have good toughness, so chips are easily troubled during CNC processing , and cutting parameters and reasonable tool design are required.

Strong corrosiveness: Stainless steel is highly corrosive and is prone to corrosion, wear and other problems for tools. Therefore, it is very important to choose corrosion-resistant tools.

2. Choice of milling cutter

Tool material: Stainless steel CNC processing is suitable for choosing tool materials with high hardness and wear resistance, such as cemented carbide tools with coatings, PVD coated tools, etc. These tools can effectively extend the service life of the tool and maintain good cutting performance.

Tool geometry: For stainless steel CNC processing, tools with larger front and rear angles are generally selected, which can effectively reduce cutting force and friction and reduce temperature during processing.

Tool coating: The coating plays a key role in the service life and cutting performance of the tool. Common coatings include TiN coating, TiCN coating, AlTiN coating, etc. These coatings can reduce the coefficient of friction and prevent the occurrence of problems such as tool sticking and thermal cracking.

Cutting parameters: During the process of CNC processing of stainless steel, it is also crucial to choose the appropriate cutting parameters. Reasonable feeding speed, cutting depth and cutting speed can ensure the life and processing quality of the tool.

Stainless steel CNC machining is a task that requires technology and experience. Choosing the right tool is very important to improve processing efficiency and quality. It is recommended to choose tool materials with high hardness and wear resistance, appropriate tool geometry and coatings in stainless steel CNC processing, and adjust them according to the specific cutting parameters to obtain the best processing effect.
