Mounting instruction of collet chuck holder
Mounting of collet chuck holder 344 1305 on your lathe TU2506 and TU2807V.
Proceed as follows.
Mark out the position of the lathe
chuck at the spindle flange before dis-
mantling with an e.g. felt-tipped pen.
Dismantle the lathe chuck.
Clean all faces of the spindle nose and
of the collet chuck holder extremely
thoroughly.
Remove threaded studs from the lathe
chuck and install into the collet chuck
holder.
Measure the true running of the spin-
dle nose. Mark out the greatest posi-
tive amplitude of the dial gauge at the
spindle nose with an e.g. felt-tipped
pen.
Attach the collet chuck holder to the
spindle flange, hand tighten the nuts.
Tighten in the nuts stepwise once and
uniformly alternating at least three
times in successively (only this way
you will get the best true running).
Measure the true running of the collet
chuck holder at the conical surface.
Position the collet chuck holder by
turning each 120° at the spindle flange
to the highest run out precision is
achieved.
Mark out the position of the highest cir-
cularity accuracy of spindle flange with
collet chuck holder and assemble then
the collet chuck holder on the highest
circularity accuracy position.
