Dish End Hole Automatic Cutting Machine

Product Description

QIZHI CNC Boiler Nozzle Flame Cutting Machine, Suspension Type, Suitable for Nozzle Internal Welding
1. Key Features
The main machine head is suspended at the end of the crossbeam of the column and boom type machine. The column and boom type machine moves the head to the position where it needs to be cut before cutting, and the column and boom type machine does not participate in linkage during the cutting process. The cutting working is independently completed by the CNC nozzle cutting system.
The cutting head adopts the center hole positioning laser light device to achieve fast and accurate positioning. The relative position between the head's rotation center and the centroid of the hole to be cut can be determined by adjusting the cross slide mechanism of the cutting machine. Then the positioning error of the workpiece and the cutting head is easy to control.
Specially designed center hole positioning laser light device can quickly determine the spatial position of the main machine head and shorten preparation time.
Full English/ Chinese human-machine operation interface, complete parameter settings, and real-time monitoring of the operating positions of each axis. Adopting a hybrid stepper motor and driver, it has the advantages of high torque, low vibration, low heat generation, and high reliability. θ, X, Y, Z the four axis linkage rotation can achieve CNC cutting of holes in orthogonal and eccentric situations.
The groove forms can be V-shaped, X-shaped, Y-shaped, and K-shaped, and continuous variable angle grooves can be cut to meet welding requirements.

It can meet the requirements of opening holes (orthogonal, eccentric) on the cylinder and cutting continuous variable angle grooves. It can meet the requirements of opening holes (orthogonal, eccentric) and cutting continuous variable angle grooves on ellipsoidal and spherical heads.
It can meet the requirements of cutting the end of the nozzle/ connecting pipe (including flange connecting pipe) that intersects with the pressure vessel/ cylinder, with two types: saddle type (orthogonal or eccentric) and insertion type (orthogonal or eccentric);
3. Application
This machine is mainly used in industries such as boilers, chemical pressure vessels, nuclear power equipment, etc., where holes are opened on pressure vessels or dish ends, as well as pipe intersecting line cutting. Equipped with a CNC flame cutting system, cutting work can be completed with high quality and efficiency. It is suitable for cutting materials such as carbon steel and low alloy steel. This equipment is suitable for chemical equipment manufacturing, power plant boilers, pressure vessels, nuclear power facilities, etc.
