Lots has happened since my last post... I got married again... 3rd times the charm right?
Another big event is that I am now in a position to get my milling machine down from St Louis. As fate would have it... I needed to go to St Louis for work... so while here I prepped the huge machine for shipping.
Before Prep Work
After Pulling the motor and prepping.
The machine weighs about 3,200 pounds (1450 Kg)... yes folks... that's 1.5 tons of fun. The garage door is 81 inches tall (2.05 Meters)... with the 5HP motor and Z-axis mounted... 95 inches (2.4 meters) it was NOT going to fit through the garage door. Taking them off just got it down to size.
78 1/2 inches tall. (About 2 meters)
Nothing about this machine is small... here is the power supply for the machine... it has a 220 VAC to 70 VDC system. I had it running from 115 VAC and was getting about 30 VDC for the motor drives... but on the reinstall, I'm going to go for FULL POWER and even higher speed. (Scary stuff.)
It took three of us to get the motor unmounted and on the floor safely... it weighs at least 60 pounds (27Kg) by its self, the biggest issue was getting the belt off the V-belt tension unit and lifting the motor off the mounting plate. (See below)
Motor Mounting Plate
To do it, you have to stand on top of the mill, put a steel bar through some chain rings, then lift the motor while a second person uses a screwdriver to work the belt of the pulley. Then you and a partner have to lift it off and balance it on the head of the mill. The other person shifts position to the front of the mill, and you heft this motor up and over... handing it down to the two people on the ground to receive it. (Like I said... nothing on this machine is easy.)
Motor (Left) and Z-Axis (Right)
Afterward I decided to lay the Z-Axis on the bed and wrap with packing plastic to keep it from getting beat up. I wrapped the motor as well as possible too to protect the spring plate and pulley assembly too.
All prepped and ready to go. Motor in foreground wrapped in plastic.
I manually turned the screws and cranks... still feels fine... everything still moves smoothly. I guess my packing EVERYTHING in a thick coat of grease worked well. Once I get it shipped home, I'll have to strip everything on the mill down, and while doing that, I'll rewire it and install new limit switches and other safety features. It's gonna be a HUGE project... so if you like machines... stay tuned.
Hummm... I should do a video... or two.
