Precision Turning En 41cr4 Steel Machining Materials - China

When precision turning EN 41Cr4 steel, it is necessary to comprehensively consider many factors such as material properties, tool selection, cutting parameter setting and processing environment.

The following is a detailed introduction for you: ### Material properties

EN 41Cr4 steel is an alloy structural steel, corresponding to my country's 40Cr steel.

It has high strength, toughness and hardenability, and can obtain good comprehensive mechanical properties after proper heat treatment.

However, in turning, its hardness and strength will affect the cutting force and tool wear, and its thermal conductivity is relatively low, which easily generates heat accumulation during cutting, resulting in reduced surface quality and shortened tool life.

### Tool selection

- **Tool material**: Carbide tools can be selected, which have high hardness, wear resistance and hot hardness, and can withstand high cutting temperatures.

For some high-precision and high-efficiency processing requirements, coated carbide tools can also be considered.

The coating can further improve the wear resistance and anti-adhesion properties of the tool.

When machining EN 41Cr4 steel with higher hardness, ceramic tools are also a good choice.

They have higher hardness and thermal stability, but are more brittle, so it is necessary to choose reasonable cutting parameters.

- **Tool geometry parameters**: The rake angle is generally selected to be a smaller value to enhance the tool edge strength, usually 0° - 5°; the back angle can be appropriately increased to reduce the friction between the tool and the workpiece, usually 6° - 10°; the main deflection angle is selected according to the workpiece shape and processing requirements, usually 45° - 90°; the rake angle can be selected from -5° - 5° to control the flow direction of the chips and improve the impact resistance of the tool.
