Pair Heads SXBJ-18 Large Size Plate Edge Milling Machine

A. Outline on SXBJ-18 Double Heads Large Sheet Metal Plate Edge Milling Machine:

1. Specialty: SXBJ-18 is the biggest model in the product family of XBJ and SXBJ series Sheet Metal End Milling Machine;

2. Applying Site: This SXBJ-18 big equipment is usually applied in working sites and facilities where produce large scale equipment, such as Port Machinery/ Offshore Oil Gas/ Shipbuilding/ Bridge Construction, etc.;

3. Counterpart: The model larger than SXBJ-18 is FXBJ-18 Four Milling Heads Large Sheet Metal Plate Beveling Machine, which has 4 sets of milling heads in one set of machine, working on the same working stroke of 18,000 mm.

B. Application of SXBJ-18 Double Heads Large Sheet Metal Plate End Milling Machine:

1. Working Environment:

1) The attached and below pictures show a set of Wuxi JACK SXBJ-18 running at customer site:

2) The open air installed Wuxi JACK SXBJ-18 Large Sheet Metal Plate Edge Milling Machine: (Fig.1)

3) This SXBJ-18 large machine is installed in open air ground. This is the common practice in the introduction of large scale double heads long stroke SXBJ model Sheet Metal Plate Edge Milling Machine:

4) For the sake of the large overall dimension of the SXBJ-18 model, it is difficult to find an ample place inside ordinary indoors workshop, for putting into use the large machine;

5) Under such outdoors working conditions, proper and strict daily use and maintenance is of vital importance, for maintaining stable and high standard operating level of the SXBJ-18 large machine;

2. Overall Dimension and Preparation on SXBJ-18 Double Heads Large Sheet Metal Plate Beveling Machine:

1) The SXBJ-18 Large Sheet Metal Plate Edge Milling Machine has:

a) 24,000mm (18,000mm+ 6,000mm) length mechanical machine body;

b) 3,000mm height of pressing beam and working table;

c)  3,500mm depth, or cross section width of working table;

2) It is necessary to prepare foundation before delivery of the machine.

Common practice is we Wuxi JACK provide foundation drawing ahead of machine shipment to customers, and customers make foundation based on it;

3. Usage of SXBJ-18 Large Sheet Metal Plate End Chamfering Equipment:

1) Why need Edge Milling Machine? In the manufacture of Port Machinery and other heavy duty units, before welding operation, the large and heavy steel plates need to have the process of making welding groove on its edges, to get the best quality of welding seam in the subsequent fabrication operation;

2) Edge Milling Machine, or the other name is Sheet Metal Plate Edge Chamfering Machine, is for completing on this important task;

3) The most seen types of bevels and chamfers that are available made with XBJ and SXBJ series machine, is designated in the below illustration: (Fig.2)

4) The superior quality finished beveled steel plate, produced from Wuxi JACK Sheet Metal Plate End Milling Machine: (Fig.3)

4. Advantages of Double Milling Heads Configuration for Sheet Metal Plate Edge Chamfering Machine:

1) High efficiency: Configuration of double milling head is the “Useful Weapon”, for completing on plate end milling operation in the machine;

2) Straight/ Top/ Bottom edges one time finish: It can be either milling out welding grooves on top and bottom edges chamfering at the same time: The leading set of milling head is responsible for milling upper and straight edges groove in the machine;

3) The following set of milling head is responsible for making lower chamfer;

4) Or, the two pieces of milling heads can carry out plate edge chamfering operation, on two pieces of small steel plate respectively.

5) The running of double milling heads in Wuxi JACK SXBJ-18 open air Large Sheet Metal Plate Edge Milling Machine: (Fig.4)

C. Main Units of SXBJ-18 Large Sheet Metal Plate End Milling Machine:

XBJ and Series Sheet Metal Plate End Milling Machineis assembled from outsourcing components and self made parts:

1. Outsourcing Components in the Sheet Metal Plate Edge Chamfering Machine:

1) Two sets of milling heads, default specification is 7.5kW. For thicker workpiece to be processed, 9.3kW or even 11kW can be equipped;
