Ballscrew conversion/5th Axis
Ethan
The Taig mill is more than capable as it comes, so there has been a long discussion on the taigtools list as to the advantages 2nd otherwise of ballscrew conversion. I have many customers who do very fine work with the bog standard machine, once they have become used to keeping it 'well tuned'. As for the fifth axis being supplied on the bed of the taig - again, the design of the Taig provides a good amount of clearance over the bed to do that, but providing the fifth asis by simply mounting a second rotary table on the back of the spindle gives a MUCH bigger working foot print.
Nothing against cncconversions - he is trying to do a good job, but his targets just seem to be wrong at present.
