3. The Uniqueness Configuration of This GFXBJ-23 Large Size Edge Milling Machine:

Compared with ordinary structure machines for plate end milling,

1) Quantity of milling head: There are totally 5 pieces of milling units in one set of the GFXBJ-23 Large Size Edge Milling Machine, compared with 1 or 2 sets in ordinary machine of end milling;

2) Power of milling head: 4 sets of milling head in this GFXBJ-23 model machine for edge milling on large plate is 11kW, compared with 7.5kW in ordinary specifications machine of end milling;

3) Milling Angle of milling head: The milling angle of each milling head in GFXBJ-23 model Large Steel Plate Edge Milling Machine is 0°~ 85°, compared with 0°~ 45° in ordinary specifications machine of end milling;

4) Overall Structure: The structure of GFXBJ-23 model Heavy duty Large Edge Milling Machine is completely different from ordinary structured machine for end milling, as you can find from attached photo and below design sketch:

Design sketch of Wuxi JACK GFXBJ-23 model super large heavy duty Special Edge Milling Machine: (Fig.3)

5) Overall Dimension: The overall dimension of this GFXBJ-23 model Large Scale Edge Milling Machine is around 2 times that of ordinary structured SXBJ-18 model machine of sheet metal end milling.

C. Special Structure of GFXBJ-23 Heavy duty Large Edge Milling Machine:

1. This is what distinguishes this GFXBJ-23 model large size machine from ordinary machine for edge milling:

2. The standing gantries of Wuxi JACK GFXBJ-23 model Heavy duty Large Edge Milling Machine: (Fig.4)

3. As can be found from the above photo, there are two sets of longitudinal stationary gantry standing at both ends of this Large Plate Edge Milling Machine, serving as hanging racks for the long lengthways pressing beam;

4. Before edge milling operation of the Large Size Edge Milling Machine, the pressing beam responsible for lengthways large plate edge milling is hung on the large machine mechanical gantries, which can be moved backward under the drive of hydraulic cylinders, leaving space for workpiece loading into the large machine, for carrying out edge milling operation;

5. The workpiece is hoisted onto loading rack and worktable of the Large Plate Edge Milling Machine by means of the overhead traveling crane;

6. Then the pressing beam can be moved back to its original place just above the large scale machine worktable for edge milling job, for carrying out large plate beveling.

D. Main Units of the GFXBJ-23 Heavy duty Large Special Edge Milling Machine:

1. The GFXBJ-23 Heavy duty Edge Milling Machine is composed of:

1) 4 groups of milling heads and its moving carriages;

2) Guiderails and its safeguarding unit;

3) Mechanical feeding system of the large scale machine for steel plate edge milling task;

4) Hydraulic system, hydraulic uplifting loading and unloading unit into and out of the Heavy duty Edge Milling Machine;

5) Automatic scrap disposing unit during running of the Large Size Edge Milling Machine;

6) Conveyor and its rack;

7) Electric control system;

2. Guideways are heavy loading linear guiderails, with great loading capacity and high precision of guiding, fitting for this GFXBJ-23 model Large Plate Edge Milling Machine;

3. The 4 sets of milling heads adopted in this Large Edge Milling Machine:

1) 11kW MU-9S model produced in Taiwan;

2) It is transmitted with precision gear, with strong points of reasonable structure, reliable performance, wide speed range, high rigidity, low noise, high efficiency, and convenient operation, specifically suitable for this Heavy duty Large Edge Milling Machine;

3) Its spindle revolution is adjustable within the scope of 9 grades among 65~ 715 rpm, catering for operation of the heavy duty machine for fulfilling high level edge milling task.
