BVBA series CNC Plasma Auto Bevel Cutting Machine
BVBA series CNC plasma auto bevel cutting machine is used in the fields of ship building and construction machinery manufacturing etc. The machine is configured with precision plasma cutting torch rotating device and multi-axis CNC system, it can cut the metal plate to parts with variety of complex bevel. Blanking and bevel cutting can be finished together in cutting process. Whole implements greatly savings overall processing time, the cutting quality is also ensured.
●The patent cutting torch is light, flexible and durable, with up to six degrees of freedom.
●The unique advanced algorithm can realize the precise cutting of complex slope Angle and meet the strict AWS welding standard.
The head turntable of the chuck type cutting machine is specially designed, and de-dusting duct can be equipped to remove the dust inside the pipe from the hole in the chuck, and the dust removal performance is very good, which is favorable to the environmental protection of the factory.
Our Company's equipment provides optional configurations of 3 to 7 axles, and reference can be made to the following table for model selection according to the cutting requirements.

Cutting of groove for manifold with an opening of 360°
AWS small-angle groove cutting (composite AWS maritime engineering requirements)
Cutting of heads for pressure vessel
When welding on a thick plate of more than 30mm in thickness, it is required to improve the welding performance by virtue of groove, the traditional process is to trim the workpiece after blanking; in such case, the efficiency is very low, and it is also hard to guarantee the machining effect. Baoye M&E launched a new generation of BVBA cutter for variable groove domestically, which can complete the machining of groove while blanking. The equipment is a high-end cutting device to machine key parts that are used in shipbuilding, engineering machinery manufacturing, etc.
Its patented cutting torch is light and flexible in structure, solid and durable, and has up to 6 degrees of freedom. It can rotate infinitely and continuously within the range of 360°. Therefore, it can meet the cutting requirements of complicated groove.
Maximum positioning speed: 24,000mm/min
Range of groove tilt angle: ±45°
Range of rotation angle: infinite rotation
Collision protection device for plasma cutting torch
The boiler water wall tube panel is a very special workpiece, with great machining difficulties and high machining demand. It will take time and efforts to process such workpiece if adopting traditional mode of manual operations, and also it is hard to guarantee the processing quality.
For such problem, Our company adopts a mode combining infinite rotary variable-angle cutting technology and cold machining to solve the difficulties in cutting the workpiece perfectly. The cutting torch can change the tilt angle intelligently according to the shape of workpiece, thus cutting the workpiece in a high-quality manner.
The cutting machine, adopting the mode of 3D 8-axle control (among which 5 axles links together), can cut the 3D space curve on the surface of tube panel. By configuring a laser detector, the cutter can position the cutting position of tube panel accurately, and scan the relative position of tube and steel fat, and feed back the data to principal computer, so as to ensure accurate cutting of tube panel.
Also, it can not only cut the ends of tube panel, but also cut opening in the middle: diamond, triangle and other 2D shapes.
After adding with plasma, the equipment can cut the tube panel and open groove on the ends in one operation, so as to cut the tube panel conveniently and effectively.
The equipment has been used by many domestic users for a long term, and obtained remarkable economic benefits.
