The Cutting of High Manganese Steel
High Manganese Steel is a special kind of alloy steel, which is mostly used in the production of wear resistant, highly wear resistant steel products. High manganese steel has excellent performance in toughness and hardness, is superior to ordinary steel and other alloy steel in its wear-resistant performance, and is the best choice for the production of wear-resistant materials. Therefore, high manganese steel is widely used in mining, metallurgy, construction, transportation, petroleum, chemical and other industries.
High manganese steel is very difficult to process, as it is difficult to cut and drill due to its high hardness, so it is difficult to cut with ordinary tools. In order to get high quality products, professional cutting tools should be selected and applied for high manganese steel. In order to save costs, reduce product defects and extend the service life of tools, high manganese steel should be machined with carbide indexable inserted cutters.
Carbide indexable inserted cutters can be used to cut high manganese steel, which can reduce cutting force, reduce cutting temperature, reduce tool wear and increase cutting efficiency. Carbide insert cutters provide more cutting opportunities and longer tool life. Carbide indexable insert cutters are more wear-resistant than ordinary steel and alloy steel, so they can be used to process high manganese steel with high toughness and hardness, which can guarantee product quality and reduce energy consumption.
The selection of carbide indexable inserted cutters for the cutting of high manganese steel should pay attention to the following aspects:
(1) According to the hardness of high manganese steel, choose high-grade cemented carbide and high-grade hard alloy to improve the tools wear resistance and toughness.
(2) According to the cutting conditions, choose the appropriate cutting edge radius, cutting depth, cutting edge angle and cutting edge back angle, so as to make the cutting edge of the tool easy to pass through the cutting area and facilitate chip discharge.
(3) According to the machining requirements, choose the appropriate cutting type, such as shoulder milling, face milling, corner milling, slotting, chamfering, etc., and then select the suitable tool geometric parameters.
(4) Reasonable selection of the parameters of tool material and cutting parameters, such as spindle speed, feed rate, etc., in order to improve quality and efficiency.
The amount of cutting high manganese steel should be decided by the actual cutting parameters. Generally speaking, the wiper angle should be small in order to extend the life of the tool, and the cutting amount should also be appropriately increased in order to reduce the number of roughing and finishing times. Generally speaking, when cutting high manganese steel, the knife should be fed at a low speed, and the feed rate should be adjusted appropriately according to the material of the workpiece. For example, the feed rate should be increased when the workpiece is made of high manganese steel, but reduced when the workpiece is made of low-carbon steel. In addition, in order to avoid excessive welt angle, the cutting amount should also be reduced appropriately.
In summary, selecting carbide indexable inserted cutters for the cutting of high manganese steel can not only improve tool durability, but also reduce cutting force, reduce cutting temperature and increase cutting efficiency. However, in order to obtain high quality products, the amount of cutting high manganese steel should be reasonably determined according to the actual cutting parameters, so as to reduce tool wear, chip accumulation and other cutting problems, and improve cutting efficiency.
