Milling Machine Parts and the Material Characteristics Milling Machine Parts and the Material Characteristics

1. What are CNC milling machine parts

CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. Their processing technology is basically the same and their structure is somewhat similar. CNC milling machines are divided into two categories: without magazine and with magazine. The CNC milling machine with tool magazine is also called machining center.

2. Milling machine parts and their material characteristics

As the composition and performance of cemented carbide for similar purposes produced by various factories are different, and the expression methods of cemented carbide brand are also different. For the convenience of users, the international organization for standardization stipulates that the milling machine parts are divided into three categories according to their chip removal types and processed materials: P, M and K.

According to the processed materials and applicable processing conditions, each category is divided into several groups, represented by two Arabic numerals. The larger the number in each category, the lower the wear resistance and the higher the toughness.

Class P alloy of milling machine parts is used to process metal materials producing growing chips, such as steel, cast steel, malleable cast iron, stainless steel, and heat-resistant steel.

Class M alloy of milling machine parts is used to process ferrous or non-ferrous metals producing growing chips and short chips, such as steel, cast steel, austenitic stainless steel, heat-resistant steel, malleable cast iron, alloy cast iron.

Class k alloy of milling machine parts is used to process ferrous metals, non-ferrous metals and non-metallic materials that produce short chips, such as cast iron, aluminum alloy, copper alloy, plastic, hard bakelite.
