Hardinge HLV-H lathe

vendredi 26 septembre 2014

Well here goes for another attempt. Nerves numbed with some red liquid sedative.



Earlier this week I was extremely fortunate to luck onto a Hardinge HLV-H precision lathe. I went to a "scrappy" who also deals in anything that he can return a profit on and regularly has older machine tools. Was quoted a price by his father who thought he should be asking twice as much. I went home and mentioned it to the wife and informed her that in 2003 they were a $60 000 USD machine. She suggested that I should go back next morning and buy it which was great news as I did not want to miss such a rare and quality lathe. I offered his price less 10% which he accepted.



It is ex CSIRO Geelong with a serial # of 7519 which appears to be about 1980 build. The machine had apparently been disconnected years ago and stored in a corner with other items. Apparently was covered in dirt, dust and grime. By the time I got it home a lot of the external dust had blown off. Lathe was built in Feltham, Middlesex, England which I think technically makes it a KL-1. It has a 440V two speed main motor of 1hp & 1/2hp and a separate 1/10hp motor on the apron for power feed. 11" over 7" dovetail bed and 9" over cross slide. 18" between centres. Weight on scales at pickup was 695kg. The leadscrew is imperial 1" X 8tpi, but the $1000> accessory metric threading package is also fitted. Has advance/retract cross slide for threading. Spindle is 1.25 through and internal is 5C with lever change, external is Hardinge taper (about 4 degree) Spindle speeds via reeves type belt drive of 125? to 3000rpm. 22 Hardinge collets in cabinet as well as travelling and fixed steadies, micrometer travel stop, drive plate and dead centre with 5C adapter. This was found in the base and has a small amount of "flight rust". Also fitted with a tiny Aa genuine Original Multifix Suisse qctp with a single holder. Coolant pump appears to be a replacement Grundfos unit.



There appears to be no perceptable wear in the dovetail bed, but has slight backlash in the rack, cross and compound slides. Dovetails are good though. Strangely there is an Australian stickered 110V transformer connected and floating around in the pedestal. Not fixed down at all.



Pics to follow.
