Platform Lifting DX2040 Steel Structure Beam End Face Milling Machine

A.       Applicable Workpieces for DX2040 Large Steel Structure Beam End Face Milling Machine:

1.       The Max. end face milling stroke in DX2040 is 2000mm height by 4000mm width, which extends specifications of conventional DX series H Beam End Face Milling Machine;

2.       Available Working Parts: Benefitting from it, besides common seen welding H Beam/ BOX Beam, as shwon in the atatched first 4 photos, this medium large size H Beam End Face Milling Machine is often used in machining on large pipes: Diameters up to Φ1500mm to Φ2000mm. Shown in below photos:

B.       Operating Features of DX2040 Large Steel Structure Beam End Facing Machine:

1.       Operator Position in DX2040 and Bigger H Beam End Face Milling Machine:

1)       As shown in the attached 2nd photo and below, operator of the DX2040 H Beam End Face Milling Machine needs to stand on motor drive lifting operating platform, so as to get access on high level maching point:

2)       Working on Wuxi JACK DX2040 Large Steel Structure Beam End Facing Machine: (Fig.3)

2.       Two Types of Operating Platform in Wuxi JACK DX Series H Beam End Face Milling Machine:

1)       DX20xx and Larger models: For valid vertical milling stroke 2000mm and higher, operating stand is motor drive elevating type, which is integrated with milling carriage;

2)       Light and Standard Model: While in DX1520 and smaller models of H Beam End Face Milling Machine, the operating stand is separated from lifting style milling carriage, and fixed at bottom of the upright column, without elevating ability, shown in below photo:

3)       Wuxi JACK DX1520 H Beam End Face Milling Machine operating platform: (Fig.4)

4)       The reason is obvoius: For DX15xx and smaller H Beam End Face Milling Machine, operator can take care on the entire height range of workpiece, by just standing on workshop floor; While when operating on DX20xx and above models of the End Facing Machine, he or she needs to rise up and down to get access on higher workpieces;

3.       Operating Station in DX2040 and Bigger Pipe End Face Milling Machine:

1)       The second point of difference between DX20xx series medium to large, and DX15xx standard models End Facing Machine, is its operating panel style:

2)       The overhang fixed height operating panel in DX15xx series H Beam End Face Milling Machine,  is changed to standing type on the lifting operating stand in DX20xx bigger models:

3)       Comparison between DX15xx and smaller H Beam End Face Milling Machine, with DX20xx and plus Large Steel Structure Beam End Facing Machine: (Fig.5,6)

C.       Upright Column Structure of DX2040 H Beam and Large Pipe End Face Milling Machine:

1.       Importance of this Unit for Steel Structure Beam End Face Milling Machine:

1)       The max. vertical milling stroke is the most crtical technical index for the H Beam End Face Milling Machine: The higher the valid vertical stroke of end milling, the more difficult in designing and production on the machine;

2)       So, DX6080 Large Steel Structure Beam End Face Milling Machine is the apex in this machine family;

3)       The reason is, with increasement of vertical column height, the corresponding risk grows on its insufficient rigidity, which may lead to flabby upright column, and consequently unstable milling head and its operation in the H Beam End Face Milling Machine;

2.       Three Types of Vertical Upright Column Structure in Steel Structure Beam End Facing Machine:

1)       In DX0820 to DX10xx series small H Beam End Face Milling Machine: (Fig.7)

Vertical column is a segment of straight square column:

2) In DX15xx series stand H Beam End Face Milling Machine: (Fig.8)

The vertical column is assembled from 2 segments of straight square columns, with an intermediate transition;

3) In DX2040 and other Large Steel Structure Beam End Face Milling Machine: (Fig.9)

The vertical column is a bottom segment of large straight square column, with a top oblique segment --- Such design of column have strongest strength and firmness;

3. In all, design and workmanship on upright vertical column, weighs heavily on successful running of DX series H Beam End Face Milling Machine, especially in large models equipment.

D.      Milling Technique in H Beam End Face Milling Machine:

1.       Purpose on End Facing with Steel Structure Beam End Facing Machine:

1)       Why have end face of pipe structure members to be polished?

2)       This is for segments of these tank members jointed togeter in high quality, by means of either welding or assembly;

3)       Before that, the rough layer of both sides end surfaces of the workpiece need to be removed, from the DX series Pipe End Face Milling Machine;

2.       Milling Technique Applied in H Beam End Face Milling Machine:

1)       The end milling under such condition belongs to ''Heavy Milling'', which means deep cut with large volumes of scrap generated, and relative lower requirement on roughness of finishness;

2)       The cutting depth in every working step of the DX2040 H Beam and Pipe End Face Milling Machine is usually 5~6mm;

3)       The working tool is small cutter head of Φ160~ 200mm;

4)       The end facing velocity is around 280~ 350mm/min., continuous adjustable and displayed in operating panel of the H Beam End Face Milling Machine;

5)       Quality of finished working parts from Wuxi JACK DX2040 Pipe End Face Milling Machine is shown in the attached 3rd photo.
