DX4080 Large H Beam End Face Milling Machine

The first set of DX4080 Heavy duty H Beam End Face Milling Machine was made by Wuxi JACK at the end of 2010, and delivered to Chinese ship building customer at Spring of 2011, as shown in the attached photos.

1. The Value of DX4080 Heavy duty H Beam End Milling Machine for Customer:

1) DX4080 is the typical large model of machine. It has capability of doing end face milling on steel structure members with cross section size up to 4,000mm height and 8,000mm width. Valid machining stroke in both height and width is custom made size;

2) Business Background: The attached 1^st set of DX4080 heavy duty I Beam End Face Milling Machine made by Wuxi JACK was completed in end of 2010, and delivered to a customer from Shipbuilding industry in Wuhan city, China at the beginning of 2011. It has very good and stable performance over the past 10s years, and gained high recognition from the customer. Since then, more and more Large scale H Beam End Facing Machine of DX40xx and larger (DX5080/ DX6080) have been made for customers both in China and abroad, and have acquired word of mouth from customers;

3) Application: Workpieces for these Heavy duty H Beam End Milling Machine with 4,000mm plus vertical stroke and higher are usually large scale special made structure members, for applied in Shipbuilding/ Power Plant/ Oil Derrick, etc., as shown in the 2^nd photo.

2. Technical View on DX4080 Heavy duty H Beam End Face Milling Machine:

Not every producer in Machine Tool Works Industry has strength on design and producing such big and heavy duty equipment. The key points on capability of delivering Large I Beam End Facing Machine lies in ability on developing special designed and manufactured machine frame, especially its base bed and column:

1）The base bed and column of these DX40xx (and larger) Heavy duty models machine are made from finely machined integral members, welded into the shape of structure, and integrally annealed post welding;

2）Production Process Control: For heavy duty models of machine, its cross section size of body and column are calculated and made specifically larger with sufficient margin for the purpose of making strong and sturdy structure, especially vertical column, which determines rigidity and firmness of end face milling job in the machine;

3）Mechanical Main Frame: As can be seen from the attached 3^rd/ 4^th/ 5^th photos, there are groups of stiffeners deployed all along machine body of the Heavy duty H Beam End Milling Machine, especially the connection between upright column and base bed, making the main frame of entire set of large machine more solid and durable;

4）Raw Materials: The raw materials for making mechanical system of the Heavy duty models machine is 20~30mm thickness high strength steel plates and section steels;

5）In all, the prerequisite on successful performance of the Heavy duty H Beam End Face Milling Machine, is its mechanical system has features of firm, stable, and good precision, without deform;

6）Preparation on Heavy duty H Beam End Face Milling Machine: 

Customer have two preparatory jobs before putting it into use:

a)  Make foundation based on the drawing from us;

b) Make workpiece rack of corresponding size. (Please check the first picture) Usually for super large size of machines from DX4080 model, customer prepare on workpiece platform based on practical condition;

7）For Heavy duty H Beam End Milling Machine, after commissioning at our company, its machine body is disassembled, shipped to customer site, assembled into an integral machine again, and then made commissioning. The levelness of machine base bed and verticality of upright column are critical control parameters in installation.
