Large Size And Stroke SXBJ&FXBJ&GFXBJ Series Edge Milling Machine

A. Distinguishing Features of and Definition on Large Sheet Metal Plate Edge Milling Machine:

1. Specialty and Characteristics of Large Plate Edge Milling Machine:

1) Position: As a kind of heavy duty equipment, large models with long edge milling stroke is the most eye catching branch, in the product family of XBJ& SXBJ& FXBJ& GFXBJ series Edge Milling Machine;

2) Features: What distinguishes large models machine from other models lies at: Its big dimension and hence wide variety of variations in mechanical structure and function units; As well as combination of advanced function and high precision;

3)  Wuxi JACK SXBJ-18 large model machine for edge milling, and its delivered superior quality finished groove on edge of steel plate: (Fig.1)

2. Definition on Large Edge Milling Machine:

1) Edge Milling Stroke: Different models of machine differs on the basis of edge milling stroke. Max. effective working stroke of 12,000mm and above products can be classified as large models;

2) Models: The corresponding models of Large Edge Milling Machine are from SXBJ-12 and above;

3) Specification: For standard models machine, the upper limit in effective stroke for large plate edge milling is 18,000 mm; For sophisticated moving structure, the lower~ upper limit in stroke for large plate beveling is 19,000 to 23,000 mm;

B. Classification on and Application of Large Edge Milling Machine:

1. SXBJ Series Double Heads Large Sheet Plate End Milling Machine:

1) Scope: The corresponding models fall within the range of SXBJ-12 to SXBJ-18 (18m max. edge milling stroke);

2) Structure: Majority of the Large Plate Edge Milling Machine have its two sets of milling head unit installed at single side of working table, which is operating side of the machine;

3) Special Type: Minority of the special made large model machine have its two sets of milling heads installed at both sides of the machine work table: One set at each side;

2. Four or Five Heads Configuration FXBJ and GFXBJ Models Heavy duty Large Edge Milling Machine:

1) Scope: The “smallest” specification on Four or Five Heads large models machine is 18m. The corresponding model is FXBJ-18; The “largest” edge milling specification is 23m, or GFXBJ-23 large size machine;

2) Structure: Four or Five Heads configuration FXBJ& GFXBJ series large model machine have its four sets of milling head installed at both sides of the working table, 2 sets at each side. The 5^th piece of milling head is installed at lateral side of the machine;

3. Application of Large Sheet Metal Plate Edge Milling Machine:

SXBJ& FXBJ& GFXBJ series large model machine are basically applied in the field of Civil Project (Bridge Construction)/ Port Machinery/ Shipbuilding, etc..

C. Technical Characteristics of Heavy duty Large Edge Milling Machine:

1. Very Seldom Single Head Configuration in Large Sheet Steel Plate Edge Milling Machine:

1) Although in theory, large model machine can also be equipped with single milling head, in practical use this is rarely adopted;

2) The reason is, in daily operation, solitary head configuration has too low production efficiency for edge milling operation, especially when it is necessary to have large plate welding groove cutting on both top and bottom edges of workpiece;

2. Applicable Workpieces and Its Handling for Large Sheet Plate Edge Milling Machine:

1) Workpieces of large models machine are fairly big size, large thickness and heavy weight metal plates, especially material of carbon steel plate;

2) For example, for GFXBJ-23 model, the largest single piece of steel plate can be: 23m length, 4m width, 200mm thickness, and 145 Ton weight. So, supporting hydraulic unit is a standard and requisite function for operation of the large size machine for edge milling;

3) Wuxi JACK Unique Owned Unit: Correspondingly, the pushing in and pulling out of huge steel plate into and out of the large size machine, should not be manipulated by hand, which is dangerous and low efficiency. Instead, automatic running hydraulic drive supporting system should be adopted in the large machines. Please see below photo:

4) Wuxi JACK exclusively owned Hydraulic drive material sending brackets for Large Edge Milling Machine: (Fig.7)

3. Mechanical Structure of Heavy duty Large Plate Edge Milling Machine:

1) Requirement: The mechanical structure of large size machine should have property of uniform high strength, with sufficient rigidity. This guarantees on stable working, consistent performance, and high precision of finished workpieces delivered;

2) Special Points of Moving Structure: Besides, for the convenience of handling big and heavy workpiece into and out of the large size machine, as well as large plate edge beveling, the entire mechanical body or parts of the machine should get movable ability. Please check below photo:

3) Special Points of Lateral Side Edge Milling: Some application of large machine needs the 3^rd function of end face milling at lateral side of workpiece. Please check below photo:

4. Higher Power of Milling Head in Large Size Heavy duty Edge Milling Machine:

1) Demand: Thicker thickness of workpiece steel plate needs higher capacity on large steel plate edge beveling. This can get deeper cutting depth available during edge milling operation;

2) Equipping 9kW/ 11kW Milling Head: So, milling head of higher power 9kW/ 11kW are usually used in Large Edge Milling Machine. In this sense, although in the field of edge milling application, “Small size model machine does not mean light duty”, but “Large model machine usually implicates on heavy duty ones”;
