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 shown in the attached first 4 photos, this medium large size model 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 2^nd photo and below, operator of the DX2040 machine needs to stand on motor drive lifting operating platform, so as to get access on high level machining point:

2)  Working on Wuxi JACK DX2040 large model 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 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 obvious: For DX15xx and smaller models, 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 machines, 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,  is changed to standing type on the lifting operating stand in DX20xx bigger models:

3) Comparison between DX15xx and smaller models machine, with DX20xx and plus larger models: (Fig.5,6)

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

1. Importance of Upright Column for Steel Structure Beam End Face Milling Machine:

1) The max. vertical milling stroke is the most critical technical index for the machine: The higher the valid vertical stroke of end milling, the more difficult in designing and production on the machine;

2) So, DX6080 model 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 machine;

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

1) In DX0820 to DX10xx series small models: (Fig.7)

Vertical column is a segment of straight square column:

2) In DX15xx series standard models: (Fig.8)

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

3) In DX2040 and other Larger Models : (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 Face Milling in 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 together 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 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 finish effect;

2) The cutting depth in every working step of the DX2040 model machine is usually 5~6mm;

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

4) The end face milling velocity is around 280~ 350mm/min., continuous adjustable and displayed in operating panel of the machine;

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