C. Structure and Main Units of DX0815 H Beam End Face Milling Machine:
1. Structure and Working Principle of the Special Design Flange Milling Machine:
This special design equipment has the similar structure and working manner as conventional H Beam End Face Milling Machine:
1) Its execution unit the 7.5kW milling head is installed onto motorized drive upright column;
2) During Work:
a) Y Axis Movement: Under motor drive and controlled with VFD, the milling head moves up and down along the heavy duty precise linear guiderail on the upright column, fulfilling Y axis vertical direction end face milling operation;
b) X Axis Movement: The upright column moves along horizontal base bed, also under motor drive and controlled with VFD, fulfilling X axis horizontal direction end face milling operation;
3) Workpiece Secure: The special design workpiece fixture clamping table is put alongside lefthand of the mechanical main body of the Flange Milling Machine:
4) Overall appearance of the unpainted DX0815 Metal Structure Flange Milling Machine for testing at Wuxi JACK facility: (Fig.5)
2. Main Units of DX0815 Steel Structure Flange Milling Machine:
1) Upright Vertical Column, Including: Milling head/ Vertical slides/ Column body/ Elevating transmission mechanism/ Guard cover;
2) Horizontal Slides, Including: Work table/ Machine body/ Feeding transmission system/ Guard cover;
3) Hydraulic Clamp Working Table, two pcs, hydraulic station;
4) Electric Control System, Including: Control board/ Operating pedant/ A.C. inverter
5) Tool for Fitting Facing Blade, Including: 200 standard facing blade bed/ Fitting tool, etc.
D. Operation on DX0815 Steel Structure Beam End Face Milling Machine:
1. Operating Zone of End Face Milling Machine:
1) During work, operator stands between mechanical main body of the machine and special design hydraulic drive workpiece clamping table, and manages on operation by means of overhang pendant:
2) The Russian language 360° turning hanging pendant of the DX0815: (Fig.6)
2. Workpiece Fitting On into the DX0815 Metal Structure Beam End Face Milling Machine:
This is the topic focus during business negotiation on the machine:
1) Before official running, the workpiece flange is put upright orientation, held firmly into the fixture, and face to face toward facing cutter of milling head:
2) Workpiece flange fixture and end face milling, in the DX0815: (Fig.7)
