1. This heavy duty Edge Milling Machine is for making high precision grooving on edges of metal plates, for the purpose of welding preparation;
2. With the milling angle of 0°~ 90°, not only the common seen 0° straight edge perpendicular end face, but also 90° parallel top surface of workpiece can be milled;
1) The upright milling column is being fixed on horizontally movable platform, which is driven manually, with screw gear through reducer, to control movement along Z Axis. Counter scale is used in the Edge Grooving Machine for this purpose;
2) Counter sensitivity is 0.1mm. Also, handwheel is used for fine adjustment, adjustment precision is 0.8mm/rev.;
3) To eliminate backlash in nut platform connection and screw nut mechanism, design similar to showed on figure 5 shall be used in the Edge Milling Machine as below:
1) Column fixation to horizontal movement platform is made with use of adjustment pins, for strong fixation of its position, to exclude possibility of incorrect installation in the Plate Edge Milling Machine;
2) To ensure milling precision and high rigidity during milling process in the Edge Grooving Machine, movable platform, clamping pads and wedge shall be made according to scheme similar to showed on figure 6 as below:
1) Guides of carriage in this Plate Edge Grooving Machine shall be machined after welding, it is not allowed to have any thermal cutting marks on working surfaces;
2) These guiderails are heavy duty precise linear ball bearing guiderails, assembled onto mechanical bed of this End Grooving Machine;
1) In this advanced control Edge Milling Machine, rotating of the milling head is driven with motor, detected with encoder, indicated with angle ruler, and managed with HMI (Human machine interface);
2) Rotating angle can be controlled with control panel of this Edge Milling Machine, rotation angle step is 0.1 degree. On each milling head metal protective cover shall be installed;
1. Feeding system of this heavy duty Plate Edge Grooving Machine consists of roller tables, 4 pieces of racks driven with hydraulic push devices, with 4 pieces of lifting hydraulic devices;
2. According to workpiece width in the Plate Edge Milling Machine, thrust pins are installing into the hydraulic push devices;
3. Workpiece moves forward with thrust pins and hydraulic push devices;
4. After workpiece is placed on the working table of the Plate Edge Milling Machine, it clamps by hydraulic jacks on the upper beam of this Edge Grooving Machine.
1. Milling head driving load indicator (Am meter) is installed on control panel or on rear side of the milling heads;
2. And motor protects against overcurrent is installed in control box of the Edge Milling Machine moving carriage;
3. All electric components of each milling unit should be installed into the independent electric cabinet of the Edge Milling Machine, fixed on the side of milling units’ column through vibration dampers.
