Im at the point where its time to finish out the Larios horizontal mill taking up space in my shop.
The original control panel, used switches to:
master power On/off Spindle High/Off/Low Spindle CW/off/CCW Table Left/off/Right
Coolant pump on/off
The issues are
Motor is two speed, with 2 seperate 3ph windings for high and low
Table is single speed 3ph motor and reversed winding power for opposite direction.
The switches are toast. Finito. Bad. Blown, Kaput. No replacement. Endit
The table has a mechanical Rapid that works the opposite of the feed direction..whatever the feed direction is. So you can make a cut, rapid back to the start and hit her again.
I scrounged up some bat handle 3 phase switches..but I cant see any way to make them do the above, without having a shitload of them hanging off the side of the machine.
So I got an 18x 22" electrical box, mounted it to the side of the machine and mounted fuses, a control transformer, and gutted a Hardinge control cabinet for the contactors. Ill mount the control switches on the top of the cabinet, where there is easy access. Spindle has a clutch lever to engage/disengage as does the table feed.
The issue Im having is...will I ever need to run the table in the opposite direction visa vis the spindle rotation? I do have the vertical attachment..but ever mounting it is unlikely . Shrug
Or can I simply ignore having the ability to feed in a direction opposite the normal direction when feeding into a horizontal mill cutter? Climb milling in other words? Is climb milling all that important on such a mill?
Im having something of a mental block on this...I can see it..but dont know that Id ever climb mill. The machine IS very tight and can do climb easily without any issues. But will I ever need to do it?
If I put in a contactor for reversing the table...its gonna get really crowded in that box. Its doable, shrug..but is it something I should do?
I suppose not needing a reversable spindle would be the second issue...hummm...that would save me even more space.
Having to install a reversing relay..and then taking two more contactors to power either the high or the low windings....getting involved here....
Im not all that experienced on the actual nuts and bolt operations of horizontal millers beyond the basics.
Any suggestions...anyone?
