#Turret for hardinge hlv h lathe manual

N.rat, I'm interested in a swap, as the manual I have is for the later models. I've been talking to ZMT services, the bed plate needs to be reground as it's worn in the middle, so I'll get a new solenoid and get the powerfeed motor done too while I'm at it. This could be compensated by using thicker teflon on the carriage underside.

Backlash is now about 30 thou, as indicated at the dial. The rack is doweled to the bed casting, so it's difficult to make any adjustment to its location. One consequence, however, is that I now have a bit of backlash in the carriage rack/handwheel, due to the slight lowering of the carriage relative to the bed-mounted rack. They did an excellent job at reasonable price. I had my bed plate reground (top surface only) by Triple T engineering at Shildon. Also, the cross-slide is much smaller and simpler than the one on my machine. The photographs on page three illustrate the Early model HC, with speed control by a handwheel on the front of the cabinet. There is no date information in the manual, but the UK addess is given as Exeter. This would be 600 rpm and 1800 rpm at 60 Hz. It starts with a 3-phase, two speed squirrel cage induction motor, rated at 500 rpm and 1500 rpm nominal (less in practice, due to slip) at 50 Hz. I've tried to attach a couple of photographs of the manual, but the files are too large. All Hardinge HLV and HLV-H variants feature a continuously variable speed drive to the spindle. Check the motor brushes and winding resistances first. The power feed is the same as my one by the look of it - They're easy enough to fix, if the motor is OK. a solenoid operated lever with a cork pad onto the motor.Дoes the solenoid operate? (you'll hear it go clunk as the motor is powered) Or is there no braking? (replace the cork) I believe the brake is similar to the HLV-H i.e. The turret should spin to the next index as the lever is opened - There's a lever and ratchet system under the turret that is either worn, broken or, most likely, gummed-up with congealed coolant. (The plastic carriage handles had worn right through their spindle - How many time must the carriage been up and down to do that?) It looks in pretty good condition for an HC they tend to have a hard life - I repaired a couple of handles on a pair of late 70's vintage HC's a week or two ago that looked far worse. I'd guess yours is not older than the mid 1950's and maybe as late as the 1960's. HLV's that had a similar hand-wheel speed control and bed-design date from the late 1940's to 1960 when the HLV-H was introduced.

The serial number is on the flat around the spindle lock, and is 1020/1 if I have it correct it may be from the early half of the 1930's
