About Me



The latest addition to my workshop: Precise 1000U CNC milling machine!

Here is a link to the Austrian manufacturer: www.step-four.at

The new Precise 1000U is an amazing piece of kit - of course I had to fit now a proper T-groove plate to be able to clamp metal properly for machining. This proved to be a bit tricky as I didn't have a T-groove plate for fixing the work pieces! In the end I think it worked out great, tolerance is around 2/100mm (DTI):

Here the finished mill with the T-groove plate fixed:

Working with the DTI with the clumsy clamping:

Machining the aluminium profiles for taking the fixing bolt - what looks like a 3-minute job took 2 evenings to get around 1/100mm accuracy:

And here the finished aluminium profiles:



I finally decided to upgrade the mechanics to a Precise 1000U giving 1040x600x160mm milling area! Wow! Max. positioning speed is 3500mm/min.

I have now upgraded my mill to Step-Fours' high-end CNC system: XpertMill Software running under Windows and their dynamic step controller XpertCNC:

And here is the new XpertCNC controller which manages to divide every 1.8 degree step into 64 micro step and by that achieves an amazingly smooth operation:


The upgrade was worth every penny - the mill has turned into a Rolls-Royce!


 So far, my experience with both the milling machine and the software (V4Professional) has been excellent - precise, powerful and easy to use. It has been worth every pound spent. And it is so much fun!

Here is the actual milling machine:

I opted to go for the high frequency router with brushless motor, doing an incredible 50 000 rpm without hardly any noise. Especially with small diameter cutters (like 0.6mm), this makes a huge difference:

The control of the router speed is done through the software:

And here is a first result - designed on CompuFoil3D and Autocad 2004:

An additional note: Technical support is excellent, too - one year of free email and telephone support is included in the price, and whenever I had a technical question I got a satisfying reply on the same day.
