Lee,

That is the Aaron I am working with. His conversion requires machining on the castings that I am trying my hardest to avoid. Also, the machines Titan sell have a slightly different bed to mine.

So going back to the original point of the thread :-) do you have any videos of the mill running? And do you offer/will you offer 4th axis?

Ah videos....I wish I did have some for you from my own machines but not just yet...Only recently purchased the equipment to record in the quality they deserve so it is on the todo list. But I can offer you Aaron Powters youtube video of the exact same machines previous revision:

The difference between the Titan and my machines is only the bed casting.

Now in terms of CNC kits, there is a plan and I am working on it. The idea is to offer it as a 3 axes to begin with, because there are options already to add an already motorised rotary table. The real trick however is to allow you to do the CNC conversion without the need for you to machine the castings and that is where I am putting a lot of emphasis.

If you are anywhere near Bristol or can travel down, I would gladly show you the machine in person. With the CNC conversion I would recommend you also look at my quick change tooling.

Drop me a line if you have any further questions.

Doesn't that leave you one short

.

I am not exactly sure, having never contemplated the dizzier heights of CNC, but I think full positional control requires 3 linears and 2 rotationals?

I just discovered we have a fat smiley

Perfect for those of us kounting the kilocalories

Robin, you being sarcastic there, thought you had been around long enough to be well versed in the CNC world?

There is nothing stopping anyone adding a small trunion table at a later date to get 5 or even 6 axis. It just comes down to cost. The difficult bit is to do the ballscrew conversion neatly without milling the castings. After that its just bolt on bits really. With a decent controller, you can go up to 6 axes and then its just a matter of more motor drivers etc etc etc.

There is also very little cheap software that will output 5 axis gcode which puts a damper on many peoples aspirations.

Just as an aside, I am also making some fixture plate kits for these chappies to assist in part positioning and helping flip parts over easily.

When I started with computers you bought your parts from Practical Electronics or Wireless World by sending them a cheque in the post

I am now on my last decrepit knockings and you bright young things should be leaving me way behind

I also bet that you built a Heath Kit valve scope and a Sinclair micro six radio

How does the tool change work on this, is there a draw bar? Looks quite reasonable for the money! I wonder what speed the bearings would hold up to if you replaced the motor for something larger.

Hi Dave,

The tool change is the same any other R8 spindled machine. The head of the drawbar is beneath the round bobble on the head.

You can use any R8 tooling you can find on the market, as the thread is standard (7/16"), or you can use the quick change tooling I do.

The bearings can hold up to way more RPM than the spindle is currently set up to do.

I am looking at increasing the motor to be a brushless 2.2KW 6000rpm type, as well as of course a high quality CNC conversion kit

Regards
