1. The specialty of the SXBJ-9 Double Heads Steel Plate End Chamfering Equipment in this product section is its box frame structure mechanical main body, compared with gantry beam style in conventional XBJ and SXBJ series Steel Plate Edge Beveling Machine;
1) The attached and below pictures show local close up view on a set of Wuxi JACK 9000mm stroke double heads SXBJ-9 box frame structure Edge Milling Machine;
2) This is the version of first generation XBJ and SXBJ series Steel Plate Edge Milling Machine;
3) In the early days of Steel Plate End Chamfering Equipment, its mechanical machine body was usually designed and produced in such structure of half open frame: That at both ends of the Edge Milling Machine working table, there is a piece of wall board extended in the length of 1m ~1.5m, depending on plate edge milling stroke of the End Milling Machine;
1) Such way of design has strong point of sturdy and strong Edge Beveling Machine mechanical main body;
2) Besides, with an opening cut at the connection between wall board and work table of the Steel Plate End Chamfering Equipment, additional stroke of sheet metal chamfering can be got. Please check below photo:
4) Downside of such design is also obvious: Manufacturing cost and hence quotation of the box frame Edge Milling Machine is around 5% higher than conventional design of gantry beam structure Steel Plate Beveling Machine, and it occupies larger area of workshop;
5) The shipment and installation of box frame Steel Plate Edge Beveling Machine is also time consuming and laborious;
1) For these reasons, the latest decade years see upgrade on design of the Edge Milling Machine body into current style of open gantry beam, under the prerequisite of maintaining sufficient rigidity, firmness and stability of the Steel Plate Beveling Machine mechanical body;
2) At the same time, there are still some customers who prefer such structure of machine body of Edge Milling Machine.
1) During work, milling head is installed onto moving carriage, to travel along work table of the Steel Plate Beveling Machine. There are two sets of carriages in this double heads Steel Plate Edge Milling Machine;
2) Please check attached picture and below photo. The carriage consists of four main units of bottom holding rack, top vertical column, driving motors, and milling head itself;
1) This bottom rack supports the entire moving group of milling unit, which is transmitted and engaged with mechanical main body of the Edge Milling Machine, by means of precise linear guideway and racks;
2) This bottom holding rack has trapezoidal shape cross section, which has the best strength and balance for edge milling operation in the Edge Milling Machine;
This is a square cross section shaped structure, fit just above the holding rack, serving as assembling base of milling head, and its vertical position adjustment in the Steel Plate Edge Milling Machine;
1) Control board of the milling unit in the Steel Plate Edge Milling Machine is also integrated into the column;
2) The motor (2.2kW) for driving the carriage moving along work table of the Steel Plate Edge Milling Machine is inside the bottom holding rack;
3) The motor (1.1kW) for driving milling head up and down along the column is at top of the column;
This is the core working unit of the Steel Plate Edge Milling Machine, fulfilling task of making welding groove by means of sheet metal edge chamfering.
