This is a mill I got from a scrap dealer that he bought at an auction sale for $35.00. It is a Varnamo U-3 Multi Mill built in Sweden. It was equipped with a 15hp motor on the Horizontal Mill, 7.5hp on the Vertical Ram Head and 3hp on the 18 speed power feed transmission in the Knee and was 3 phase. The power feed had some major problems so I converted it to hydraulic. I made the hydraulic tank that holds 80 litres and mounted a 3hp 1ph motor driving the pump at 10 gal per minute. Controlling the speed is done with a flow control lever that allows infinite speeds 1-1/4” to 17” per minute. I ran the controlled flow and the bypass flow back to the tank individually to enhance the cooling of the oil. The hydraulic motor was a salvaged wheel motor from a commercial Toro Lawn Mower. I added a pressure gauge which runs 75psi when milling at low speed with the table and 450psi raising the knee drilling with a 1-1/2 twist drill thru 1” plate.
The Vertical Head will swivel 90 degree left or right and has an ISO 40 Taper. The Quill diameter is 5" with a 3-1/8" Quill travel and is mounted to the moveable ram that has an 8 speed transmission with speeds 110 to 2400 rpm. When the Ram is stretched out the spindle to column is 32”. To power this I removed the 7.5hp 3ph Flange mounted motor and machined a 1” thick plate the same as the motor. Then machined and mated the original flex coupling to a 1-1/2 shaft. I mounted the 1ph 5hp motor on a slotted mount to tighten the B width V belt; after the pulley was mounted I added a brake disc and caliper salvaged from a snow machine. The master cylinder was mounted on half a handlebar attached behind the control box. The brake is equipped with a limit switch when applied disconnects power from the motor, which works good for power tapping and when the park brake is applied it locks the head for doing tooling changes. The horizontal part of the Mill has ISO 50 taper and 16 speeds 40-1800 rpm. I am not using this part of the machine but could in the future.
Table Horizontal Angle L or R 0-45 deg
Table Capacity………………1500lbs.
Table……………………………..64”x13-3/4”
Longitudinal Travel……….44-1/4”
Cross Travel…………………...14”
Vertical Travel………………..20”
Coolant Capacity…………….12 gal.
Weight…………………………….7000lbs
I wanted a gearhead machine; this one was way bigger than I was looking for but after having it, I really appreciate the sturdiness, quality and capabilities of this mill.
I have used this machine for a year now and I’m very pleased how it performs and it’s a real asset to my farm shop. I am not a machinist but have used a mill drill in the past.
Information or manuals for these machines are scarce; if anyone has access to these I would really appreciate any information.
Thank you and hope you enjoy the pics.
