1) The sun shined on main frame of the DX3030 H Beam End Milling Machine. Can you identify what’s difference with this machine? ---
2) Maybe you have found: As its name indicates, this H Beam End Face Milling Machine has casting base bed, instead of the conventional base bed of welding structure;
3) So, what’s unique with it? Let’s have a short view.
a) Casting base bed gives the machine heaviest weight (For example, this DX3030 Welding Structure End Face Milling Machine, the machine bed is over 6 ton, compared with 0.8 ton of conventional machine base bed of similar model);
b) Best stability (Of course, this does not mean conventional H Beam End Face Milling Machine does not have sufficient stability--- Just appraised under different application scenarios);
c) Best Precision: With elimination of slight floating, the end facing job can be completed with best degree of accuracy in the I Beam End Face Milling Machine;
a) The obvious disadvantage is it will add on total price of the DX series Welding Structure Member H Beam End Face Milling Machine, with the margin of around 10~15%;
b) And, need to take special care on its loading and transportation for such heavy part;
a) So, the question is, where does such “high end” H Beam End Milling Machine to be used?
b) Generally, it is used in working site of excessive high precision end facing outcome to be demanded, such as Bridge Construction, etc.
a) The 2nd photo shows a set of DX1520 with welding structure base bed;
b) Such kind of base bed takes most majority (Over 95%) in practical application H Beam End Face Milling Machine use;
c) For common type base bed DX3030, please check product section of “DX3030 H Beam End Face Milling Machine”.
a) In ordinary Welding Structure H Beam End Face Milling Machine (Refers to no CNC control), end milling speed is controlled with inverter, and displayed in digital display, as shown in the 3rd photo: There are 2 pieces of inverters in control system of the H Beam End Milling Machine to manage X axis (horizontal) and Y axis (vertical) end facing speed respectively, with speed displayed in the two digital display meters;
b) During work of the DX series H Beam End Face Milling Machine, operator needs to watch on end facing process, and manually adjust working speed by means of the speed knobs indicated with “SPEED ADJUST” on the operating panel. For detail, please check the attached video;
c) The inverter has protection functions against over current/ overload/ under voltage, which can guarantee stable and consistent running of driving motors during operation stage of the Welding Structure End Face Milling Machine;
a) All the working motions of DX series Welding Structure End Face Milling Machine are integrated into its operating panel, including the end face milling itself, and hydraulic drive workpiece rack. Please check the 3rd photo;
b) As can be observed from the 2nd photo, this operating panel is installed onto an overhanging pendant, which can be turned 360°, to any optimum working position convenient for use, for operator of the I Beam End Face Milling Machine;
c) The 4th and 5th photos catch working moment of different models of this Steel Structure H Beam End Face Milling Machine. You can see that operators operate and monitor the entire end facing process with operating panel/ end facing point on the workpiece/ Milling head of the H Beam End Face Milling Machine (This unit needs to be adjusted also sometimes during work) within arm length’s reach, without the necessity of moving or turning around.
