1) Attached is a set of Wuxi JACK CNC-DX3030 Welding Structure beam CNC End Face Milling Machine working at a Steel Structure facility;
2) You can see that there is a piece of 800~900mm height BOX Beam just finished end facing from the CNC machine;
3) So, what can this set of CNC machine do for customer?
1) The attached 2nd photo was taken at another customer site, on the same model of equipment: A set of CNC-DX3030 CNC Pipe End Face Milling Machine;
2) Thanks on powerful function of CNC controller, structure of workpiece to be end faced in CNC machines sees no limit: Traditionally, the H Beam End Face Milling Machine was basically put into use at Steel Structure industry, for workpieces of H Beam/I Beam/BOX Beam;
2) Now, with the introduction of CNC controller, connotation of the machine is expanded to wider range of workpiece, out of those made with right angle and straight edge, but also “special” shapes as well, such as round/ oblique line/ curve, etc., making the machine coming into being CNC Structure Member End Face Milling Machine, rendering service for customers from all industries involving Pipe Structure Member/ Special Shape Structure Member… For example: Oil and Gas Pipeline/ Chemical Plant/ Bridge Construction, etc.;
3) The function of this CNC-DX series machine is similar to XBJ/SXBJ/ FXBJ series Edge Milling Machine: For machining on end face or edge before next step of operation, especially welding;
4) The difference between Edge Milling Machine and CNC End Face Milling Machine lies in type of workpiece to be machined: Structure members in DX series machines, compared with metal plates in XBJ/SXBJ series Edge Milling Machine;
5) Working Unit: Both the Edge Milling Machine and Pipe End Face Milling Machine share the same specie of working unit: The 7.5kW/ 9.3kW milling head (Please see the attached 3rd photo). This is the reason in people’s mind, DX/CNC-DX-series End Face Milling Machine and XBJ/SXBJ/ FXBJ series Edge Milling Machine often reminds with each other.
a) The secret and answer on this question lies in the attached 4th photo:
b) The closed loop negative feedback controlling and management loop composed of CNC system→ Servo controller →Encoder → Servo motor;
2) In essence, CNC system is “brain” of the CNC Pipe End Face Milling Machine, and servo controller is “brain” of machine driving system. They work together and communicate with each other through interface port of RS232. Both the units have HMI (Human machine interface) for working staff of the equipment to manage and track on working process, during working period of machines;
3) The steel structure workpieces itself do not have strict demand on precision; But its end face milling operation involves precision requirement: On surface roughness of finished workpiece, which is guaranteed with face milling cutter, and contour accuracy of machined end face represented with positioning precision, which is guaranteed with the above mentioned control and driving system of the machine;
4) CNC system of the DX series CNC H Beam End Face Milling Machine is migrated from CNC Strip Plate Cutting Machine. For this reason, operating interface of the CNC has many instructions and presentations for cutting and piecing process. On the other hand, it does not influence operation in CNC H Beam End Face Milling Machine --- The operation is simpler in terms of CNC management, and less command used in the working process;
5) As a complement: The attached 5th photo shows an operator was cleaning working site of the CNC machine at completion of one shift work--- Yes, face milling and end milling operation of the H Beam End Face Milling Machine usually generate many scraps, and the fine CNC Servo systems of the machine call for a clean environment;
6) Although as professional supplier of the CNC machines, Wuxi JACK gives full proof protection on the machine control and driving system, for best and longest service terms of the machine, be sure to pay attention on its daily contamination control.
