B. The Drilling Unit and Its Working in DX1520 Steel Structure H Beam End Face Milling Machine:

1. The distinguished feature of this H Beam Steel Structure End Face Milling Machine is, besides the conventional function of end face milling, it also has drilling function;

2. Realization of Drilling Operation in the DX1520 H Beam Steel Structure End Face Milling Machine:

1) As shown in the below photo, the milling head has feeding carriage along spindle direction, in the stroke of 360mm;

2) Milling head equipped in DX1520 Steel Structure H Beam End Face Milling and Drilling Machine, and its stroke for drilling: (Fig.2)

3.  Drive Style and Feeding Speed on Drilling, in the DX1520 Steel Structure H Beam End Face Milling and Drilling Machine:

1) The feeding forward of drilling head is driven with motor reducer, in the speed controlled with A.C. inverter;

2) The feeding speed of drilling head can be adjusted based on different diameters of drilling head, from Φ10mm to Φ50mm;

4. Drilling Tool Kit in the DX1520 H Beam Steel Structure End Face Milling and Drilling Machine:

1) This H Beam End Face Milling Machine is equipped with 1 set of tool kit for fitting up drilling head, matching with ISO50 spindle;

2) Taper of the tapered hole is 7:24. Its connection is in the way of internationally universal style. The drilling head can be readily purchased in the market across the countries and regions;  

3) This Steel Structure H Beam End Face Milling Machine has 1 set of drilling tool. It is used for drilling only, not for machining on screwed hole;

4) The Drilling Head Adopted in the DX1520 Steel Structure H Beam End Face Milling Machine: (Fig.3)

5. The Drilling Coolant Circulation Systems in the DX1520 Beam Steel Structure End Face Milling Machine

1) This H Beam Steel Structure End Face Milling Machine has automatic drilling coolant circulating system;

2) There is coolant tank installed on the upright column, which supplies coolant onto drilling head by means of pump, during drilling operation;

3) Coolant flows into pit of the machine foundation, which will be pumped back into tank after being filtered off debris for reuse;

6. Foundation and Control System of the DX1520 Steel Structure h Beam End Face Milling and Drilling Machine:

1) During making foundation of the Steel Structure H Beam End Face Milling Machine, make the pit for collecting coolant. The machine foundation should be made with anti- seeping treatment;

2) The control system of the Steel Structure H Beam End Face Milling and Drilling Machine has 2 working modes of end face milling and drilling, which can be switched and selected during working.

C. End Face Milling Operation in DX1520 Steel Structure H Beam End Face Milling and Drilling Machine:

1. Due to the installation of drilling unit fit onto the milling head, this set of the H Beam Steel Structure End Face Milling Machine can only perform 0° straight face milling, instead of 0° ~ 45° tilting, in conventional DX Series H Beam End Face Milling Machine. Shown as below photo:

2. 0° Straight Face Versus 45° Slant Face Milling in H Beam Steel Structure End Face Milling Machine: (Fig.4)

D. Technical Parameters of DX1520 Drilling Function Steel Structure H Beam End Face Milling Machine:

Speed of movement is settled by different variable speed drive.
