    Hi Guys,

    Well, this thread was a very useful find, as I've just purchased a 2nd hand rotary table, and wanted to clean it up. Turns out the inside was coated in grotty oil and sludge. I PM'd Bruce...

    Yes, I could see how that would help, but being a weird little 'production' lathe, the HC doesn't have a tailstock.

    Thanks Mattij,

    I've just come up from the workshop after doing what you suggested.

    I changed the Volt/Frequency ratio from 'squared' to 'Linear' The manual notes that: "Linear is preferred for...

    Guys,

    Well, life got in the way of the lathe project, and it took me over three years to get to the point where I could fit the motor and drive the spindle. In the meantime, I continued reading...

    Thanks Adama,

    I'll probably be going with Parker BE/NeoMetric series motors and Gemini drives, as I have a friend who has access to some stripped from a decommissioned production line.

    I used...

    Thanks Guys,

    I'll take all that on board. Plugging in a conservative 4.5m/s2 with 5mm pitch ballscrews, I'm looking at the Z axis with 5Nm motor with peak acceleration rating of 8Nm, and the Y...
  7. Appropriate Acceleration Rate for CNC Machine Tools?

    Guys,

    As part of a CNC conversion of a Hardinge HC lathe, I'm using the Parker Motion Sizer software to select the correct sized servo motors and drives. I've populated the fields in the Parker...

    Hardinge HC Bed Wipers - Home Made

    Chaps,

    Last week I replaced the bed wipers on a Hardinge HC lathe with some generic Dynatech FB-AW wiper strip. While it would do the job, I thought it looked a bit ordinary, and CNCed up a pair...

    I made an inquiry with Chester Machine Tools in the UK, and they referred me to DH's Grinding Services in the UK, who apparently look after spares and servicing for these grinders. DH provided the...

    Got the drive today and ran it with the motor with no load. (It will be about a year till the lathe is finished and ready to take a cut.) Used the default settings, tweaked a bit for faster...

    Thanks,

    The encoder has a 1024 pulses per revolution, (same as this item http://www.ebay.com.au/itm/221387314984). With the encoder on the motor and a 1:1 drive ratio, I assume it's good enough....
  13. Thanks guys, How accurate? Hmmmm. At this...

    Thanks guys,

    How accurate? Hmmmm. At this stage, enough for single point screw cutting. The encoder has A, B, A-, B-, Z, and Z- output, so , should I consider something else like rigid tapping?...
  14. VFD Drive Conversion for Hardinge HC - Timing or Poly-V Belt ?

    Guys,

    I've started a dodgy CNC conversion of an old Hardinge HC lathe, and intend to replace the original two speed spindle motor and variable drive with a new motor and VFD. The plan was to use a...

    Thanks guys,

    The drive has a nominal rating of 5.5kw and 11.9 amps. The Baldor 5hp motor has a nominal amps of 8.7 amps at 415 volts. The manual for the drive makes reference to a 'sensor-less...

    Hc project starting

    Well, I had a bit of time on my hands, so decided to adopt an old HC lathe as a project. The serial number on the back of the bed is HC-5628-T. The cross slide dial is metric, which surprised me, as...

    Ugliest European Mill Ever

    Crikey, I used to think my FP1 had a face only a mother could love, until I saw this Beichle. It may be well designed for die-sinking, but you would have to hide it out the back, and throw a tarp...

    I've been playing around with a Commander SE 1hp VFD, setting it up to drive a 550w three phase induction gear-motor which will be used for a feed motor on a wood planer. No problems...

    Hmmmmmm $4k for a mill is not too bad, if it was half decent.
