On the other hand, if you're referring to a high speed drill or air grinder type of tool, there shouldn't be a problem. Hardinge wants $550 for a pair, though I found a pair for mine at a bearing supplier for $350. The angular contact bearings are made with extreme precision and are not happy with interrupted cuts as a rule, at least compared with plain bearing machines. On the milling, not sure what a PCD is, but I would approach this with some careful thought. The cross slide and compound leadscrew nuts are split like a Bridgeport's, so they can be adjusted. To answer an earlier question, the carriage handwheel clearance on a properly maintained HLV is normally around. The bigger question is why is it bruised, most Hardinge owners treat their H's with great care. Insist on seeing it under power and take a check list to check all the functions.The original accuracy of the machine in the workspace is often less than a thou and to confirm this on a used machine is difficult, so you will have to rely on its general condition and the current owners comments as to how he used it.Īs to your bruised tailstock it is hardened but a fiddle with a reamer may help. If you want a precision machine rather than a big workhorse and you can convince yourself that it is in reasonable condition then you will enjoy it. Taking them apart is a bit more complex than normal but good documentation is available to help. But I suspect patience make them available from e-bay etc. Spares are no longer completely available from the Hardinge for the HLV. The HLV-H has a wider bed and the electrics incorporate an isolating transformer in the control relay side.
The HLV-H is a later machine and superceded the HLV but is generally built on the same principles.
Ian, The HLV & HLV-H are precision toolroom lathes of the highest quality, and new will turn out the finest work.It has great screw cutting facilities, a variable speed drive and a motorised carriage.
