A little history of these lathes
Manufactured by Hercus in South Australia, these lathes were sold to many educational facilities and to countries all over the world. They were sold in the USA under the name of Rockford Pro 2000. An industrial version of the PC200 is the Novim, which comes with an industrial enclosure for coolant capture.
The lathes began as a “Computurn” model which used electronics by a company called ANCA. These lathes were stand alone cnc lathes, a small version of what might be found in industry.
These were replaced by lathes which had a Hercus control system and used an interface card in a desktop PC to connect with, and control the lathe.
These lathes used the same castings but their appearance was much changed as they no longer contained all the controls for the lathe. These were now all in the PC, apart from a small Pendant which offered some controls when in Manual mode.
Early PC200 models used a CAD/CAM software that ran in DOS on a PC that had an ISA slot (long discontinued on new PCs) and had analogue electronics. The 8 tool turret option on these lathe was operated by a small motor and gearbox and used shot pins to lock the tool in position.
As PC operating systems were upgraded, Hercus released Windows CAD/CAM software. These machines still ran analogue electronics. The last version of the machine used digital electronics and used 32 bit Windows based CAD/CAM. Both these machines used a turret with a motor and worm and worm wheel drive. Options for all these lathes included a Leader air chuck with no through hole, an air operated collet chuck, a 8 position tool turret, a tailstock, a QC tool post and a coolant pump.

  1. i find cross hole deburring tools kinda suck, i prefer to use straight-fluted countersink cutters. it requires more attention to stay consistent of course but with a depth stop it's just so easy

  2. Excellent video and format. It’s just as good a lots of channels with afew 100k subs. Keep up the good work and I’ll see you at 100k in a few months!

  3. Hey – long time no see – welcome back. Your format is fine as always. Main thing is you do the Voice Over and tell a "story" from beginning to end in audio as well as video.

  4. See, I told you it was worth putting more videos out ?. Good to see it's a bit longer and the format sure seems to have gone down well. A nice video and well explained… Martin
