DX-series CNC H Beam End Face Milling Machine

Availability:
Quantity:

Over the past decade, Wuxi JACK have delivered hundreds sets of CNC Beam End Face Milling Machine of various models for customers in China and abroad, and gained high appraisal and word of mouth from them.

Attached photos show CNC Beam End Face Milling Machine of various models and CNC systems taken at different customer sites.



1. Background of Numerical Control H Beam End Facing Machine:

1)       CNC H Beam End Milling Machine evolved from the year of around 2014~ 2015, upgraded on the basis of relay controlled DX-series I Beam End Milling Machine. The purpose is for ease and convenience of machining workpieces with round and any other special cross section shape;

2)       As we know, DX-series Beam End Face Milling Machine originated for H Beam/ I Beam/ BOX Beam use, which involves “simple” working trace of straight edge and 90° right angle. At that time, the largest selling model is DX12xx/ DX15xx I Beam End Facing Machine;

3)       Over the past decade, with the development of steel structure projects, workpieces applied in these projects witness developing trend of larger size and more complicated cross section, which poses demand on DX-series Beam End Face Milling Machine also: One is larger model, for example, DX6080; The other is numerical control.



2. Advantages of Numerical Control CNC Beam End Facing Machine:

1)       CNC H Beam End Milling Machine has powerful capability on end facing workpieces with round/ sharp angle/ Any types of irregular cross section. In conventional relay control machine, milling head can only travels along trace of either straight up/ down, or straight forward/ backward. So, when it comes workpieces like tank/ pipe etc. operator needs to spend fairly long time to fret over facer blade alignment with end face of workpiece;

2)       In contrast, in CNC Beam End Face Milling Machine, working trace of facer blade is calculated/ monitored by means of CNC controller, which any contour of end milling is easily available;

3)       Besides, there is workpiece library in backstage operating system of CNC, in which common seen types of workpiece cross section, including circle/ triangle/ arc, etc., can be selected within seconds;

4)       In all, with introduction of CNC controller, productivity of CNC Beam End Facing Machine is raised 10% ~ 20%, and precision on end milling contour is also improved in an order of magnitude. For detail, please check product section of DX3530 and DX3535 CNC Beam End Face Milling Machine.



3. Technical Features of CNC I Beam End Face Milling Machine:

1)       Driving System and Control:

a)       Please check the 5th photo. In CNC Beam End Facing Machine, driving system is servo motor and encoder, instead of Y-series asynchronous motor in conventional equipment;

b)      Control on end facing job is closed loop, with CNC system as core element, and encoder as negative feedback, instead of open circuit in conventional relay control equipment;

2)       Speed Control:

In CNC Beam End Face Milling Machine, end face milling is managed with CNC controller, instead of A.C. inverters in conventional equipment;

3) Operation:

a)       In CNC Beam End Facing Machine, end milling function is realized on CNC system soft keys. So, operating panel is simplified into a very small operating pendant leaving only management on hydraulic workpiece rack;

b)      Operation on CNC Beam End Face Milling Machine is intuitive and user-friendly --- Just keying in parameters of the workpiece that to be end milled;

c)       Operating interface in CNC system has multiple languages to choose from;

4) Valid End Face Milling Stroke (Workpiece Size):

a)       The most matching size for CNC Beam End Facing Machine is small ~ medium duty, up to DX3535. Working stroke higher than 3500mm is not applicable for numerical control. One reason is servo motor is usually applied in small and medium power, rather than high power of 5kW and above; The other is workpieces in large H Beam End Facing Machine usually have relatively simple cross section, which does not need numerical control.
