Wow that tool changer is fast, compared to a carousel changer. Never seen one in use before. Looks an interesting build.

That is actually slowed down from the speed it comes from Chiron, the previous owner had damped the cylinders and I just kept it the same as I am in no hurry

Previous company I worked for, bought a couple of DZ18's (A new design at the time) and sent us on maintenance training in Germany about 18 years ago. Amazing machines when they are working, but twin spindles (DZ = twin spindle, FZ = single spindle) and a tool carouselle, meaning four arms attempting to move and twist in sync, within 1-2 seconds, O.k. when brand new, but after 12 months of production, a nigtmare.
Nice design and prototype grinder (even though I've got a Hudmut one).

Yep a carouselle, well an endless chain running horizontaly (with the tools suspended vertically down), along each side of the machine. Each spindle had two arms, one around the tool in the spindle and the second ready to collect the next (pre-selected) tool from the chain.
At the time they produced components for the then new BMW Mini gearbox and engine mounts for Rover cars.

The previous owner said the only issues he had had with the changer was burst pipes although he had obviously crashed a few holders as I think 4 were missing. The air valves were leaking a bit and the manifold also so eventually I replaced them all with SMC ones from eBay. But the thing is nearly 30 years old so I can't complain.

The Basket tool change as far I know, was very reliable. The twin spindle machines that used a basket tool around each spindle, just as reliable. The company I worked for at the time bought one of the first DZ's with a "tool chain" that Chiron produced and then dispite all the problems with the first, bought another 12 months later, that was no better 
Other than the issues with the new design of tool changer, they did have fragile spindles, that seemed prone to damage for no apparent reason. After 2 years, some re-designing and updates by Chiron, the machines preformed well.

Mine was partly my fault, a lot of the holders I got had pullstuds in them but a lot didn't so I bought a load and only put them in the ones that didn't have them. Should have done all of them as one of the originals failed just as a 25mm dia cutter was starting cutting at a depth of 6mm but because of that it tried to take a 30mm cut
I sorted it as best I could by turning the taper in the lathe, it is close but not quite there and really can't afford to try again due to the design of the drawbar lock. It really needs bored out and sleeved.
I am wondering if this could produce the two stage angles Richard uses. I know hudmut version was single cut but it looks like this one could grind the shallow angle first but then adjusted to grind the more acute tip angle?

That was one of the things I wanted it to do. Whether it will work or not, time will tell

Nice to see a new idea Iv got something similar to your over head arm all done in soildworks all so Iv added a detent in there for a bit of repeatability. One thing I did learn from my grinder is the dust in threads is a killer and the finer the worse it gets for gargling that's why I did a slid fit on the to half's over a thread. Im not picking faults just helping with what I learnt as for drilling the bolts for guides on to fit all sizes tungsten's there is a lot to take in to account if you start making these for resale.
On another note I see your using a CS-labs controller in you machine there a good system I got one of them cheap pendants of ebay and added the module my self saved me £250.
My new mill showed up last week with a 4th axis so Ill be making more grinders to soon and may be the new one ill share it with you.
And Iv just spotted your user name out paths have crossed before you have been very help full with me in the past with Mach3. Once more thank you on that subject.

I am unlikely to sell them as I have plenty of other work and often turn down production work as it numbs my head
Thought about the dust, it is a 2mm pitch so hopefully course enough. I was thinking about adding detents but will wait until I have used it to see, fisrtly whether it is any use and secondly which positions I use.
I have used the CSMIO's for years, best controllers I have used with Mach. On the Chiron and the wee lathe I just had the MPG and switches on the panel itself so no handheld required. On the plasma I made my own hand held pendant.
Pics below.

What's a hand held pendant?I am unlikely to sell them as I have plenty of other work and often turn down production work as it numbs my head

The thing you see circled below, it can be lifted off the panel and taken with you to jog the machine amongst other things. On mine I just have the MPG (Manual Pulse Generator) which is used to move the machine about, Axis select switches to choose which axis I am moving, increment size so that each click of the MPG (100 clicks per rev) can either be 1mm, 0.1mm or 0.01mm (can be set to 0.1mm 0.01mm or 0.001mm) and lastly a feed override pot.
