1) The sun shined on main frame of the Wuxi JACK 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 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 models machine does not have sufficient stability--- Just appraised under different application scenarios);
c) Best Precision: With elimination of slight floating, the end face milling job can be completed with best degree of accuracy in the machine;
a) The obvious disadvantage is it will add on total price of the 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” machine to be used?
b) Generally, it is used in working site of excessive high precision end face milling 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 of H Beam End Face Milling Machine use;
c) For common type base bed DX3030, please check product section of DX3030 model.
a) In ordinary models electric control 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 machine to manage on X axis (horizontal) and Y axis (vertical) end facing speed respectively, with speed displayed in the two digital display meters;
b) During work, operator needs to watch on end face milling 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 on 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 machines are integrated into its operating panel, including the end face milling itself, and hydraulic drive workpiece rack. Please check the attached 3rd photo;
b) As can be observed from the attached 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 machine;
c) The attached 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 face milling process with operating panel/ end face milling point on the workpiece/ Milling head of the machine (This unit needs to be adjusted also sometimes during work) within arm length’s reach, without the necessity of moving or turning around.
