Steel Plate Curve Cutting Machine

The steel plate curve cutting machine is mainly used for groove cutting of various carbon steel plates. During the processing of wind turbine hydraulic tower and water pressure pipe, we should carry out cutting of large amounts of sector plate and hyperbola with various beveled edges.

This cutting machine can carry out cutting of V shaped and K shaped bevel on both sides with different curvature of the plate at the same time. The cutting finished parts can be directly used for automatic welding after rolling forming.


1. The steel plate curve cutting machine consists of cross beam and two longitudinal end frames. The two end frames adopt low structure design, thus ensuring the machine stability. The two groups of horizontal main cutting torch respectively adopts AC servo driving system which can be controlled independently. It realizes horizontal driving by using gear and rack. The longitudinal movement of the machine adopts bilateral drive which is realized by gear and rack.

2. The CNC cutting control system is the specific control system specially developed by Jinfeng for the steel plate curve cutting machine. It adopts 32 bit Linux real-time operating system, thus realizing multitask operation with high performance, high stability and virus interference resistance. This means that the machine can carry out multi-operation such as file edit, graphics treatment, parts nesting, network transmission, parameter setting, cutting torch gating etc. during parts processing.

3. This cutting machine is equipped with 17" LCD touch screen with high resolution, so that it has intuitive interface and simple operation. Through the network interface, it can be connected with random PC in the network, realizing cutting file transmission, processing site monitoring and the subsequent software update. Thus, it brings great convenience for operators and programmers.

4. By using this machine to process the bi-arc groove curve parts, you just need to know the essential parameters of the parts, and there is no need of manual programming.
