As the most popular model of DX series Welding Steel Structure BOX I H Beam Side Face Milling Machine, DX1520 is not only widely used in milling on regular steel structure workpieces: BOX/ Cross/ I/ T/ H Beam, but also the other common seen workpieces of: Pipes/ tanks, etc., which has cross section shape of circular:
1) Conventional BOX Beam and H Beam for end face milling: (Fig.1)
2) Pipe for end face milling: (Fig.2)
3) Operation Site: A set of Wuxi JACK DX1520 model machine, works at customer site, performing side face milling on a piece of Φ1,200mm diameter pipe structure member of 10m length: (Fig.3)
1) Wide Use: As mentioned in the above, not only round shape cross section workpiece like pipe structure member, but also all kinds of welding structure members, like H Beam/ I Beam/ BOX Beam… can be machined with this automatic machine;
2) Specifications: DX1520 belongs to one of the most popular models. It has:
a) 1,500mm vertical and 2,000mm horizontal valid end face milling area, perfectly match with:
b) Finished H Beam delivered from HB1500 H Beam Production Line, and finished BOX Beam from BOX1200/ BOX1500 BOX Beam Production Line;
1) This machine is an ordinary relay control type. Which means, its milling head is easily moves along straight up and down, or left and right trace, but not more complicated slant direction:
2) Without CNC, end face milling operation on pipe structure members is not as easy as CNC Pipe End Face Milling Machine:
3) Operation on this machine for pipe structure member need skillful facer blade alignment by operator:
4) Veteran operator works on pipe end face milling, with Wuxi JACK DX1520 model machine: (Fig.4)
5) On the other hand, when performing on end face milling workpieces of right angle and straight edge, the machine exhibits powerful machining capability and efficiency.
1) Necessity: To make sure eligible end face milling outcome, workpieces processed in DX1520 and other small medium sized models, need to be fixed because of its relative light weight, compared with workpieces for heavy duty machines, during end facing operation;
2) Function: Hydraulic drive clamping rack and table is for clamping workpiece tightly and reliably, dampening milling vibration and lessening noise greatly, in the process of end face milling operation;
3) Especially for pipe steel structure workpieces with long length, which have irregular cross section shape, and not easy to be leaned closely and reliably. The role of its clamp table really matters, for getting steady and high standard end face milling performance:
4) Hoisting and secure large pipe tank: 20m+ length, Φ1,200mm diameter, 3 ton plus weight, into Wuxi JACK DX1520 model Pipe Side Face Milling Machine: (Fig.5)
1) Split Type: The clamping table is a separate structure from main frame of machine. Which means, its installation position can be adjusted, based on practical condition;
2) Composition: For default configuration, one set of DX1520 model machine has 2 sets of clamp table:
a) 1 set of downward acting and sideward clamping table, with closer distance to machine main frame. The downward clamp is by means of an overhead rod, driven with hydraulic oil cylinder;
b) 1 set of sideward acting clamping table, with further distance to machine main frame, also driven with oil cylinders:

2) When length of workpiece is too long to be clamped reliably, the 3rd set of side acting clamping table, should be equipped with machine: (Fig.7)
3) Close distance view on cross section direction, clamping pipe tank structure workpiece, into Wuxi JACK DX1520 model Pipe End Face Milling Machine: (Fig.8)
Mechanical main body of a typical set of DX series machine includes three main components of:
1) This is foundation of the entire set of machine. The two critical indexes for its performance are enough strength and strict levelness;
2) The demand on its strength and rigidity is guaranteed with its raw material and process technology:
a) This bed is made of high strength section steels and welding structure members;
b) After being welded and fabricated into shape, the entire set of base bed is heat treated integrally with annealing, guaranteeing non deformation and long time use of machine:
c) Horizontal bed of Wuxi JACK DX1520 model machine: (Fig.9)
3) Levelness of horizontal bed is guaranteed with heavy duty precise linear guiderail assembled, and installation process at customer site. There is stipulation on levelness of this I H Beam Pipe Side Face Milling Machine: Tolerance of 0.2mm/m, and or 0.6mm along its entire length;
4) Under special conditions, customers ask for base bed made of casting, which has much higher manufacturing cost, but special capability:
Wuxi JACK casting base bed I H Beam End Face Milling Machine: (Fig.10)
1) Work Motion: During work, upright column moves along horizontal precise linear guiderail of the base bed, in the speed of either end face milling operation (150~ 800 mm/min.), or idle (1200 mm/min.) when not in work;
2) Installation: This upright column is installed onto horizontal base bed, by means of machined installing plate;
3) The critical control point for this upright column, is its verticality with respect to base bed, which should be checked rigorously during installation and commissioning of the machine:
2 sets of assembled Wuxi JACK DX1520 model I H Beam End Face Milling Machine: (Fig.11)
1) This is core working unit of machine. It is installed onto the upright column, by means of its machined installing plate, in the orientation of horizontal --- In all of the DX series welding steel structure End Face Milling Machine, milling head is installed in horizontal position, for the purpose of fulfilling on end face milling job:
Milling head unit, being installed onto upright column, in Wuxi JACK DX models machines: (Fig.12)
2) Double Types of Speed: Same as the upright column, during work, the milling carriage moves up and down in either working speed (150~ 800 mm/min.) when carrying out end face milling job, or in idle speed (1200 mm/min.) when not in work.
