    Default 1964 Monarch 10EE Module Drive Tool Room Lathe $3500

    Up for sale is this 1964 Monarch 10EE tool room lathe. It is the 20" between centers model and it has the electronic lead screw reverse function (ELSR). This was originally a module drive machine but it has been converted at some point in its life. The original 5HP General Electric DC motor and original back gear assembly is still in use and has not been removed. The previous owner has installed a Hampton Products Co. solid state DC converter in the machine. I do not know anything about this drive but it does appear this company is still in business. I am able to power this machine up and get the spindle running. The ELSR functions exactly like it is supposed to. The speed change is done with a potentiometer near the coolant on/off switch. I can not get the machine to go over 1000 RPM the way it is set up but it does move into forward and reverse with the lever just as I would expect it to do. I could not get the coolant pump contactor to engage with the switch. I have not tried to troubleshoot these two issues. The spindle sounds nice and smooth and the back gear works as it should. The back gear is louder in forward than it is in reverse which seems normal to me. All the power feeds work as expected and the gearbox shifts into all positions like expected. The half nuts operate like expected and the carriage moves fine when they are engaged. The machine is running in many of the photos. This is 230V 3 phase powered.

    I have cleaned this machine up a bit and topped it off with oil. This would make a great project for anyone who is looking to own one of these great American lathes. I have a forklift and can load this onto a truck or trailer. Thank you for looking. Located in New Berlin, WI 53151

    GREAT positive news!

    The previous owner has installed a Hampton Products Co. solid state DC converter in the machine. I do not know anything about this drive but it does appear this company is still in business. I am able to power this machine up and get the spindle running. The ELSR functions exactly like it is supposed to. The speed change is done with a potentiometer near the coolant on/off switch.

    It could be easily made to go faster by dropping the field power, but at the expense of substantially reduced Torque and stability, as it is already significantly underpowered, even if smooth and capable of making many chips.

    Three-phase may be wired to it, but it isn't using all legs.

    The drive is on the right is single-phase input, outputs but 180 Volts DC to an armature nameplated for 230 VDC, and known to be over-driven by Monarch to 245-255 VDC, even so. This limits both max power and max RPM by more than just the ratio of 180 to 230, as these goods are not perfectly linear. Basically, the 5 HP motor is being run at less than 3 HP and about 1/4 of its design maximum RPM - shorted on available current as well as Voltage.

    Which is still decent - just not full OEM 10EE performance!

    The drive on the left supplies the Field, and is also single-phase in, but should have all the Voltage as well as current the motor needs, plus a substantial reserve.

    Anyone who wants to do can follow a PM thread and upgrade it back to full OEM performance as to power and max RPM by use of a different DC Drive capable of the full Voltage and power needed.

    It isn't that hard, and there is plenty of help and guidance, "Right here, on PM".

    If I didn't already have TWO 10EE, plus another fine lathe, your one would be VERY tempting at the price asked!

    All the best at finding it a new "minder".

    I picked this machine up yesterday. I'll start a thread in the Monarch forum when I get started on cleaning and fixing it up.
