#Harrison m300 lathe plus

Do have a rotary 5.5hp convertor as well, its not man enough exceptionally noisy and spindle easy to get to slow down with menial cuts on just kept for emergency. New machine replacement in excess of ВЈ18,000. Ex Ministry of Defence machine with very little use. Run mine from 1ph 240V to 3ph 400V digital inverter exactly the way Harrison intended keeping control boards, isolator switch and the like its just plug and play like it would be used in factories. Used Harrison M300 Gap Bed Centre Lathe with 300mm swing x 1000mm between centres. Of course you can figure out and rewire in the spindle start 7 wires two micro switches and foot brake to inverter which is a must. Really no point in variable speed when have such a good geared head of speeds to 2500rpm from 40rpm via two 3 position selectors. I can do 28 or 32 tpi and many others, but wondered if they only list the more common ones. Coolant with vfd will also need wiring in and would fluctuate depending upon voltage supplied via rotary pot. The thread on the handguard has a 30tpi pitch but my lathe doesnt.

Not to mention doing away with all the factory necessary controls as in spindle stop/forward/reverse, brake needed for threading plus lesser needed controls. I can get mine running 400V to just about slow down at 540rpm putting a cut on, 220v usually 1/3 less output. No need to run 1ph 240V to 220V 3PH, no benefit in fact a hindrance with less power. M300 13'x25/40' Geared-head Lathes A quality asset with outstanding features and performance capabilities. Stands a good chance its dual voltage nearly all are and will say on motor plate, mine isn't with the GEC motor but coolant pump is. Have an M300 one of the few lathes to offer no faffing about to change thread pitch, just dial it in no change wheels. Harrison M300 Gap Bed Centre Lathe with 300mm swing x 1000mm between centres.
