The design of the machine is similar to the Aciera or a Maho, with the table moving in X and Z, spindle in Y. The spindle can be flipped over for horizontal machining.

We decided to get a machine with a small work-envelope (table XY travel is 260x170 mm), but with good rigidity and hopefully good precision. The machine is around 4 keur but with the magnetic DRO and some basic accessories plus delivery the cost is closer to 6 keur. Add another 1-2 keur for toolholders and tools.

The machine has an ISO30 taper spindle with an M12 draw-bar. In addition to the 0-13mm quick-change drilling chuck in the machine there are some tools on the shelf to the right: ISO30/MT2 adapter, an ER32 chuck, 63 mm carbide-insert face-mill, another ER32 chuck, and a tapping head. There is a 150 mm rotary table on the machine to the lower left. A new 100mm precision vise is on order but not delivered yet.

This means there are now no excuses for not finishing my very delayed lathe project...

Rough milling:

 

Finish milling:

The 1000 mm long hull plug will be made from a left and a right half, and each half consists of three parts. This is the first part from the bow to around 300mm.

Got the XYZ servos mounted and tuned. The first video shows a test program with some drilling G-codes. Rapids are set at 5000mm/min with around 400 mm/s^2 accelerations. Following errors stay below 0.02 mm. The second video shows a 40 mm face-mill at 3000 rpm cutting a 20 mm wide aluminium bar with 1 mm depth of cut and 500 mm/min feed. We think this is pretty good for this size of minimill. The stability and sound will not be as nice as this without linear rails, ballscrews, and a good spindle.
