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.

  1. Single part= engine lathe 10-100 parts CNC lathe 100-10000+ Screw machine 10000+ cold forming. I always used the example of spark plug bodies. GM made them on screw machines in 5 seconds. Too long so they cold formed them in 1/2 second each machine sounded like a slow machine gun.

  2. Good information. I'm looking for a smaller CNC lathe to make parts for a model engine. The Tormach 15L slant lathe looks good, but I took the class on in in their facility and although it was capable of doing the job, it's more lathe than I needed for the money.

  3. Should have a view of that machine from farther away segwaying into each video good filler and I'm sure those who haven't seen it would like to know what your working with

  4. For a small CNC like say CNC converted bench top lathe this is not bad. I am thinking of getting a small but heavily build lathe to convert into CNC – say old Hardenage lathe or Colchester Chipmaster (I have a manual one and love it). Obviously for custom made parts in small tiny orders (say less then 100) – the economy of scale would easily kill any attempt to compete with catalog items.

  5. As an old machinist is is disappointing that no one knows how to sharpen a drill for brass anymore. I did like how they used the drill to break the edge on the hole. We used to use a center, end, chamfer tool. Three operations at once. You don't really need the center when you have a short drill like that but you get the hole chamfer out of it. I believe I could make that part faster on a W&S turret lathe. Center, end, chamfer / roller turn, die head, cut off with cross slide and a probe in the turret to catch the part.
    Brass is fun to machine. Tools last for ever. I worked for a company where we produced a finished pressure gauge socket every second. Every index produced one part. Custom made machine.

  6. Very relaxing, I ran Wickman's back in the late 70's , ran 3 machines at same time , each pushing 600 pph, pulling parts and checking dimentions, onto next one, the fog in the shop (8 machines) was chest level, all for 6.50$ hr
