High-strength steel refers to steel with a tensile strength of 785MPa or more. It has high strength, hardness, and toughness, and is widely used in construction, bridges, automobiles, aerospace, military, and other fields. However, during the production and processing of high-strength steel, stress can be generated due to various reasons, leading to deformation, warping, and other issues that can affect the quality and service life of the product. Therefore, a series of measures need to be taken to remove stress, and precision leveling machines are a very effective method.

Leveling machines are used to flatten and level the surface of workpieces before they are processed by CNC machines. This is necessary because many workpieces may have slight variations in their thickness or flatness, which can affect the accuracy of the CNC machining process.
