Stainless steel is widely used in CNC parts processing due to its superior corrosion resistance, high and low temperature resistance, wear resistance, and strong plasticity, etc., stainless steel products have large hardness, so the difficulty of stainless steel parts processing is relatively large. Stainless steel parts are mainly used in environments with high corrosion protection requirements, such as chemical equipment, medical equipment, Marine accessories, food processing machinery and equipment, electromechanical shafts, valve stems, weighing sensor elastomers, petroleum machinery parts, etc.
People familiar with the machining industry know that the hardness of stainless steel is high, so the tool used is also different from the general material of the tool, stainless steel parts processing tool should pay attention to what problems?
1, tool selection: different tool materials are different, machining stainless steel cutting force, high temperature, to choose high strength, good thermal conductivity of cemented carbide, such as tungsten titanium tantalum alloy;
2, blade: stainless steel material is hard, should keep the sharp edge of the processing tool to reduce work hardening;
3, pay attention to the chip breaking groove: The grinding tool should pay attention to, because the stainless steel chip has the characteristics of toughness, the chip breaking groove grinding on the front knife surface of the tool should be suitable, so that the cutting process can interrupt the chip, chip tolerance and chip removal.
