Ordinary leveling machines can adjust the flatness of workpieces through pressure and the movement of leveling rollers, and are suitable for leveling workpieces with low surface requirements, such as some thin plates, plates, pipes, etc. Meanwhile, ordinary leveling machines are relatively low-cost and easy to operate, making them suitable for use by some small and medium-sized enterprises. However, for some workpieces with high precision requirements, it is necessary to choose a precision leveling machine for leveling treatment to ensure the quality and accuracy of the workpiece.
