Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building material processing, and specifically relates to a building material cutting equipment. BACKGROUND

[0002] With the development of the construction industry towards standardization and industrialization, the traditional cutting equipment has been difficult to meet the modern construction needs. In the construction process, the cutting of materials such as stone, metal profiles and concrete plates is an indispensable link. At present, the commonly used building material cutting equipment mainly includes a disc saw, a plasma cutting machine and a water jet cutting machine. However, these devices still have many limitations in practical application. The traditional disc saw relies on a high-speed rotating saw blade for cutting. Although the equipment cost is low, the cutting efficiency and precision are difficult to balance. On the one hand, the saw blade is easy to wear during cutting and needs to be replaced frequently, resulting in increased downtime. On the other hand, the saw blade cutting is easy to produce large vibration, causing the cutting surface to be uneven, and the dimensional error can reach ±3mm, which is difficult to meet the strict standards of the component precision of prefabricated buildings.
