M1 level

1、 Structure: The weight can have an adjustment chamber, and the total volume of all adjustment chambers should not exceed 1/10 of the total volume of the weight.

2、 The chamber should be sealed with water and dust. The adjustment chamber can be sealed with a threaded plug or knob.

3、 Material: The weight should be made of one or more pieces of material * *, and the material's * * * properties should be equal to or better than gray iron.

4、 Under normal use, the hardness and strength of the material should be able to withstand the impact of home use.

Grade: M1, M2, M3

Shape: Lock type, block type, circular, rolling type, cylindrical

Surface condition: In order to improve the durability and hardness of the weight, an appropriate metal coating or coating should be applied to the surface of the weight.

Advantages of cast iron weights:

Due to its low mechanical properties, graphite acts as a crack or cavity in the steel matrix, which destroys the continuity of the matrix, reduces the effective load-bearing cross-section, and easily leads to stress concentration. Therefore, its strength, plasticity, and toughness are lower than carbon steel.

Introduction to Cast Iron Material:

① Gray cast iron. The carbon content is relatively high (2.7% to 4.0%), and the carbon mainly exists in the form of flake graphite. The fracture surface is gray, abbreviated as gray iron. Melting point (1145-1250 ℃), small shrinkage during solidification, * * pressure and hardness close to carbon steel, good shock absorption. Used for structural components such as machine tool beds, cylinders, and casings.

② White cast iron. The carbon and silicon content is relatively low, and carbon mainly exists in the form of cementite, with a silver white fracture surface. During solidification, there is significant shrinkage, which can easily lead to shrinkage and cracking. High hardness, high brittleness, unable to withstand impact loads. It is commonly used as a blank for malleable cast iron and in the production of wear-resistant components.

③ Malleable cast iron. Obtained by annealing white cast iron, graphite is distributed in a flocculent form, abbreviated as ductile iron. Its organizational performance is uniform, wear-resistant, and has good plasticity and toughness. Used for parts with complex shapes that can withstand strong dynamic loads.

Gray cast iron weight: Most or all of the carbon in this type of cast iron exists in the form of free graphite flakes, with a dark gray fracture surface. It has excellent mechanical properties and good machinability, and is widely used in industry.
