1) Position: As a kind of heavy duty equipment, Large Sheet Edge Milling Machine is the most eye catching branch, in the product family of XBJ& SXBJ& FXBJ& GFXBJ series sheet End Milling Machine;
2) Features: What distinguishes Large Sheet Plate Edge Milling Machine from other scopes of End Milling Machine 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;
1) Working Stroke: Edge Milling Machine differs on the basis of edge milling stroke. Max. effective working stroke of 12m and above products can be classified as Large Sheet Plate End Milling Machine;
2) Models: The corresponding models of Large Edge Milling Machine are from SXBJ-12 and above;
3) Specification: For standard Gantry Beam structure Large Edge Milling Machine, the upper limit in stroke for large plate edge milling is 18 m; For sophisticated moving structure, the lower~ upper limit in stroke for large plate beveling is 19 to 23 m;
1) Scope: The corresponding models fall within the range of SXBJ-12 to SXBJ-18 (18m max. edge milling stroke) Large Edge Milling Machine;
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 heavy duty End Milling Machine;
3) Special Type: Minority of the special made Large Sheet Plate Edge Milling Machine have its two sets of milling heads installed at both sides of the End Milling Machine working table: One set at each side;
1) Scope: The “smallest” specification on Four or Five Heads Large Plate Edge Milling Machine is 18m. The corresponding model is FXBJ-18; The “largest” edge milling specification is 23m, or GFXBJ-23 large size Heavy duty Edge Milling Machine;
2) Structure: Four or Five Heads configuration FXBJ& GFXBJ Large Plate Edge Milling Machine have its four sets of milling head installed at both sides of the working table, 2 sets each side. The 5th piece of milling head is installed at lateral side of Large Sheet Plate End Milling Machine;
SXBJ& FXBJ& GFXBJ series Large Plate Edge Milling Machine are basically applied in the field of Civil Project (Bridge Construction), Port Machinery, Shipbuilding, etc..
1) Although in theory, Large Plate Edge Milling 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 Large Sheet Plate End Milling Machine, especially when it is necessary to have large plate welding groove making on both top and bottom edges of workpiece;
1) Workpieces of Large Plate Edge Milling Machine are fairly big size, large thickness and heavy weight metal plates, especially material of carbon steel plate;
2) For example, for GFXBJ-23 Large Edge Milling Machine, 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 Heavy duty Edge Milling Machine;
3) Wuxi JACK Unique Owned Unit: Correspondingly, the pushing in and pulling out of huge steel plate into and out of the Large Edge Milling 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 Heavy duty Edge Milling Machine. Please see below photo:
1) Requirement: The mechanical structure of Large Edge Milling Machine should have property of uniform high strength, with sufficient rigidity. This guarantees stable working, consistent performance, and high precision of finished workpieces delivered from Large Sheet Plate End Milling Machine;
2) Special Points of Moving Structure: Besides, for the convenience of handling big and heavy workpiece into and out of the Large Plate Edge Milling Machine, as well as large plate edge beveling, the entire mechanical body or parts of the Large Edge Milling Machine should get movable ability. Please check below photo:
3) Special Points of Lateral Side End Milling: Some application of Large Plate Edge Milling Machine needs the 3rd function of end face milling at lateral side of workpiece. Please check below photo:
1) Demand: Thicker thickness of workpiece steel plate needs higher capacity on large steel plate edge beveling, to be performed in Large Edge Milling Machine. This can get deeper cutting depth available during running of the Large Sheet Edge Milling Machine;
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 Machine application, “Small size Edge Milling Machine does not mean light duty”, but “Large Edge Milling Machine usually implicates Heavy duty Edge Milling Machine”;
