Wall Board Frame SXBJ-9 Sheet Metal Plate Edge Milling Machine

A. The Specialty of SXBJ-9 Box Frame Structure Steel Plate Edge Milling Machine:

1. The specialty of the SXBJ-9 double heads configured equipment for steel plate end chamfering 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;

2. The wall board box frame style mechanical structure of Wuxi JACK SXBJ-9 Steel Plate Beveling Machine: (Fig.1)

3. The open structure gantry beam style mechanical main frame of Wuxi JACK SXBJ-12 model machine for steel plate edge milling: (Fig.2)

B. Development History and Technical Features of SXBJ-9 Box Frame Structure Steel Plate Edge Beveling Machine:

1. Background of SXBJ-9 Steel Plate Edge Milling 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 machine for sheet metal edge milling;

2) This is the version of first generation XBJ and SXBJ series Steel Plate Edge Milling Machine;

3) In the early days of this automatic equipment for steel plate end chamfering, 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 1,000mm ~1,500mm, depending on plate edge milling stroke of the machine;

4) Short distance view on Wuxi JACK SXBJ-9 model box frame structure machine for steel plate edge milling: (Fig.3)

2. Strong Points and Downside of SXBJ-9 Box Frame Steel Plate Edge 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 large equipment for steel plate end chamfering, additional stroke of sheet metal chamfering can be got. Please check below photo:

3) The cutting open in the mechanical frame of Wuxi JACK SXBJ-9 box frame Edge Milling Machine: (Fig.4)

4) Downside of such design is also obvious: Manufacturing cost and hence quotation of the box frame structure machine of edge milling  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 machine for steel plate edge beveling is also time consuming and laborious;

3. Mainstream and Niche Product of Steel Plate End Chamfering Equipment:

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 machine mechanical body of steel plate beveling;

2) At the same time, there are still some customers who prefer such structure of machine body of machine for carrying out edge milling operation.

C. Technical Details of SXBJ-9 Steel Plate Edge Milling Machine:

1. Milling Head Carriage in the Steel Plate End Milling Machine:

1) During work, milling head is installed onto moving carriage, to travel along work table of the machine for steel plate beveling job. 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;

3) The milling head moving carriage in Wuxi JACK Steel Plate Edge Milling Machine: (Fig.5)

2. Bottom Holding Rack in the Steel Plate End Chamfering Equipment:

1) This bottom rack supports the entire moving group of milling unit, which is transmitted and engaged with mechanical main body of the machine of edge milling task, 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 machine;

3. Top Vertical Column for Vertical Driving Milling Head in the Steel Plate Edge Beveling 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 machine for steel plate edge milling performance;

4. Electric Control and Driving Motor of the Steel Plate End Milling Machine:

1) Control board of the milling unit in the machine of steel plate edge milling  is also integrated into the column;

2) The motor (2.2kW) for driving the carriage moving along work table of the 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;

5. Milling Head of the Steel Plate Beveling Machine:

This is the core working unit of the machine, fulfilling on task of milling out welding groove by means of sheet metal edge chamfering.
