1) This is the largest and heavy duty model in the product family of XBJ and SXBJ series single or double heads configuration Metal Plate End Milling Machine;
2) In the Sheet Metal Machinery and Welding Equipment industry and market, only very small percentage of professional suppliers have real capability on developing and manufacturing Large Sheet Metal Plate Beveling Equipment;
3) The technical difficulty lies in maintaining its uniform precision, sufficient rigidity, and stable performance of SXBJ-18 and other large Edge Milling Machine;
1) As can be found from the attached photos, this set of SXBJ-18 Large Sheet Metal Plate End Milling Machine is installed and operated at an indoors working environment;
2) This can protect the Edge Milling Machine from negative impact of direct infiltration of wind, rain and storm, which is more easy to acquire stable and precise performance of the Large Sheet Metal Plate Edge Miller;
3) Comparatively, there are some outdoors installed SXBJ-18 or other Large Sheet Metal Plate End Milling Machine being put into use at customer facility. This is considered out of available ample space for easy operation and broad material handling zone of the large Edge Milling Machine;
1) Applicable Sites: This SXBJ-18 heavy duty Sheet Metal Plate Edge Chamfering Machine which is equipped with double milling heads is usually applied in Heavy Industry/ Projects/ Construction Sites, such as Steel Structure, Shipbuilding, Railway, Power Plant..., etc.;
2) Function: The SXBJ-18 and other large Edge Milling Machine fulfil the task of welding groove making on single piece of huge size sheet metal plates; Or, several pieces of smaller and medium size metal plates can be pressed in a row in the Large Sheet Metal Plate Edge Miller to be beveled together;
1) Edge Milling on Top and Bottom Edges: To complete both top and bottom edges chamfering with one time traveling stroke of milling head carriage along worktable of the double heads long stroke Edge Milling Machine, the two sets of milling head share the tasks of making welding grooves on top and bottom edges respectively;
1) Based on thickness and designed cutting depth of the Edge Milling Machine, the working speed on edge milling should be able to adjusted continuously within certain range (130~ 1000mm/min.), with intuitive display at the same time, during running of the End Milling Machine;
2) Such velocity modulation is controlled with A.C. inverter, adjusted with speed knob, and display in digital meter, which are installed on operating panel of the Edge Milling Machine;
1) Workpiece Type: In XBJ and SXBJ series Sheet Metal Plate Edge Chamfering Machine, the workpiece can be either an integral piece of big and heavy steel plate, or two or more pieces of smaller steel plates;
2) Workpiece Feeding In and Out: These steel plates are sent into the Sheet Metal Plate Edge Miller by way of a row of front extension floor fitting supporting racks;
3) Workpiece Assistant Loading: This group of supporting racks can be assisted with optional hydraulic loading unit, so that steel plate, especially large and heavy steel plate can be pushed into and pulled out large Edge Milling Machine with more convenience and safe operation;
a) Shown in the attached photos and below picture, the workpiece steel plate is secured firmly onto XBJ and SXBJ models Steel Plate Edge Chamfering Machine worktable, by means of an array of hydraulic drive Jacks;
b) The quantity of these hydraulic jacks depends on the maximum working stroke of the Edge Milling Machine. In the case of this SXBJ-18 Large Sheet Metal Plate Edge Miller, it is usually 30 pieces.
