1) Most majority models in the product family of XBJ and SXBJ series Edge Milling Machine are equipped with one or two sets of milling heads, which account for over 95% of total volume;
2) Meanwhile, there are a branch of special type machine for edge milling on large plate, which has four to five sets of milling head and its moving carriages, in one set of such heavy duty Sheet Metal Plate Welding Auxiliary Equipment, as shown in the attached photos;
1) Wuxi JACK GFXBJ-23 Five Heads large model machine for Edge Milling on sheet metal plate, being installed at customer site: (Fig.1)
2) FXBJ series four heads Sheet Metal Plate Welding Auxiliary Equipment:(Fig.2)
1) Position: Four or Five Heads configuration FXBJ and GFXBJ series large scale machine for edge milling is “Giant” in the product family;
2) Powerful Capability: These large Welding Auxiliary Equipment are usually applied for making welding grooves on both sides of large size workpiece metal plates in high efficiency:
3) The workpiece steel plate and its both sides four corners beveled with grooves, held into working table of Wuxi JACK GFXBJ-23 Sheet Metal Plate Welding Auxiliary Equipment: (Fig.3)
1) All the Four to Five Heads Sheet Metal Plate Edge Beveling Machine belong to heavy duty large models for sheet metal plate edge milling;
2) The “Smallest” model has the longest effective edge milling stroke of 18,000mm; And the “largest” model has 23,000mm maximum valid stroke;
1) Milling Head Quantity: Four to five sets of milling heads in one set of the machine;
2) Milling Head Power: Higher power 11kW are often adopted, compared with 7.5kW in conventional edge milling models machine;
3) Thickness of Workpiece: Sheet metal plates to be edge beveled in Four to Five Heads Large Plate Edge Milling Machine are usually have max. thickness of 200mm, compared with 40mm~ 80mm up limit in “Ordinary” edge milling models machine;
4) Workpiece Loading and Unloading: Considering the huge size and heavy weight (Sometimes around 70 Ton per piece of steel plate) in the four to five heads heavy duty machine of plate edge milling, hydraulic driving supplementary loading system is often equipped in such large size Welding Auxiliary Equipment. See below photo:
5) The hydraulic assistant steel plate loading system equipped in Wuxi JACK four to five edge milling heads large models machine: (Fig.4)
1. Where Used: Four or Five Heads Heavy duty Plate Edge Beveling Machine is usually applied in the field of big Civil Project, the most often examples are Steel Structure, Bridge Construction, especially Bay Bridge;
2. Why Need: To be specific, in such big projects, there are huge amounts of large size and heavy weight metal plates used as raw materials, which need to have large plate beveling on its both edges and four corners in high productivity, and hence calls for application of Four or Five sets of milling heads configuration in these heavy duty machines for plate edge milling;
The sheet metal plates to be processed with such large Welding Auxiliary Equipment have size range of:
1) Length Range: Max. 18,000mm to 23,000mm;
2) Width Range: Max. 3,000mm to 4,000mm;
3) Thickness Range: 6~ 200mm;
4) Weight: Up to 70~75 Ton, which are really colossuses;
1) Making welding groove on large plate into four corners of workpiece sheet metal plate, in the position of upper and lower chamfers, in the form of straight and slant and blunt edges, or even round shape grooves. See below photos:
2) The common seen types of welding grooves to be made on double edges of steel plate, from four to five edge milling heads large machines: (Fig.5)
3) The round shape chamfers made from Wuxi JACK Four to Five Heads Edge Beveling Machine: (Fig.6)
1) The four sets of main milling heads are arranged in symmetry at both sides of the Sheet Metal Plate Welding Auxiliary Equipment working table. Shown in below photo:
2) The symmetrical installation of the four sets of 11kw milling heads in Wuxi JACK FXBJ-18 model machine with four milling heads configuration: (Fig.7)
3) This may remind you of the similar structure in “Conventional” size machine, such as SXBJ-12. The difference is, in SXBJ-12 model Edge Beveling Machine, there is 1 set of milling head carriage assembled at both sides of the machine work table respectively;
These special points include but not limited to:
1) Moving style instead of fixed type pressing beam, in the machine for edge beveling on large plate;
2) Side beam added with small stroke for accommodating movement of pressing beam in the large model machine.
