With the passage of time, science and technology is developing at a high speed. In addition to traditional mechanical products, metal materials have been widely used in most emerging industries after precision parts processing, including 3C industry (Computers, communications, consumer electronics)It is the most representative emerging industry. Metal Cutting is a very important production link in the manufacturing process of products. Because the tool will directly affect the quality of the product during the machining process, how to choose the right tool is inevitable. The following is an example of turning, how to select tools when processing different materials. 1. Steel cutting steel can be classified as non-alloy steel, low alloy steel and high alloy steel. Different types will affect turning processing Proposal 1. 1 Non-alloy steel (The carbon content is 0. Within 55% of steel) Non-alloy steel is difficult to break chips and has a bonding trend during turning (Debris tumor) For Chip control and Chip breaking, precision parts should be processed to achieve the highest possible feed. Chip accumulation can directly affect the surface quality of parts and the service life of tools, so high cutting speed is used to avoid chip accumulation on the blade. 1. The cutting performance of low alloy steel depends on heat treatment (Hardness)With alloy content. When turning, the most common tool wear is caused by flank wear and Crescent pit wear. Therefore, cutting tools with extremely high resistance to flank wear should be preferred. 1. High alloy steel high alloy steel is similar to low alloy steel. The higher the alloy content and hardness, the lower the cutting performance. When high alloy steel with hardness up to HB450 is used for turning precision parts, more heat will be generated in the cutting area, which is easy to cause plastic deformation. Therefore, cutting tools with high plastic deformation resistance and cutting edge strength should be considered. 2. Stainless steel cutting stainless steel can be classified as Ferritic/Martensitic stainless steel, austenitic stainless steel and duplex (Austenite/ferrite) Different types of stainless steel will affect the processing of turning recommendations 2. 1 ferrite and martensitic stainless steel are two types of stainless steel and low alloy steel have similar cutting performance. In precision parts hardening martensitic stainless steel, tools with high requirements against plastic deformation should be used. 2. 2 austenitic stainless steel in stainless steel, austenitic stainless steel is the most common, but because common tools will have Crescent pit wear, plastic deformation and chip accumulation tumor during processing, turning will also produce 'work hardening', but also because 'work hardening' produces groove wear, thus forming burrs on the tool. Therefore, round blades or small main deflection angles should be selected to prevent groove wear. Turning is one of the most common metal cutting methods in precision parts processing. Feed, cutting speed and cutting depth are the main parameters that directly affect tool life. Different materials have different characteristics, and there are many kinds of materials, so the matters needing attention need specific analysis.
