I need to drill some 1 mm holes in a 4 mm mild steel rod today.
The current tool of choice is a Taiwanese clone of an Emco FB2 milling machine having nice table movements, a vertical keyway to ensure good registration on height adjustments on the cylindrical column and ER16 collets.
But, maximum speed is 2000 RPM, the quill drilling movement is not exactly 'sensitive', and the collets are just a little too large.
Head drive on the column is not possible because of the backlash/friction/gravity aspects.
However, with careful work, the job will be done.
This requirement comes up occasionally and I suspect it will be more of a requirement in the future.
I am searching for a suitable economic machine with a sensitive quill movement, XY table, speeds to 20,000 RPM and standard metric small collets.
The Proxxon range is attractive, but the mills seem to be limited to 2000 RPM.
The drill is designed to accept a standard hand-held tool (which gives the 20,000 RPM) and an accessory table.

Can anyone suggest an alternative ?
Happy machining, John
