There is no doubt that a Browne and Sharp screw machine (or many others, see comments) can make these parts in seconds. BUT I have no room for a B&S machine as I work from home, even if I did why would I bother. I made these parts for customers that were happy with the minimum order quantity, price and quality. What else matters, that is what being in business is about.
This a brass gas fitting with M10x1 thread at one end and M12x1 at the other

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.
