ready
Dear customer!
Regardless of whether you have purchased a Micro miller
MF 70 CNC-ready or the compound table KT 70 CNC-
ready, you have carefully designed and manufactured
equipment for all fine, precision milling operations involving
metal, plastics or wood at your disposal.
Designed on the basis of our proven Micro miller MF 70
and compound table KT 70 models, the CNC-ready versions
of both products offer the same features in each case, but
are fitted with stepping motors instead of the familiar
handwheels.
These take charge of traversing of the compound table
carriage and the milling head during milling operations.
A CNC control system (not included in the scope of
delivery) is responsible for supplying the stepping motors,
thus enabling traversing in all three axes.
The column and compound table consist of high-precision,
surface-compacted aluminium and are equipped with
adjustable dovetail guides which are free of play. The
stable basis of the Micro miller MF 70 CNC-ready is pro-
vided by a heavy machine base made of grey cast iron.
An extremely low-vibration, carefully balanced 24-pole
high-performance DC motor ensures that the Micro miller
MF 70 CNC-ready exhibits quiet and uniform running char-
acteristics, and electronic control at every speed from
5000 to 20000 revolutions per minute provides adequate
power which enables accurate machining with even the
smallest milling cutter diameters!
The clamping jaw set included ensures that the workpieces
to be machined are secured safely and reliably.
In addition, the scope of delivery of the miller includes a
collet set with six clamping jaws with a practical selection
of diameters of 1.0 - 1.5 - 2.0 - 2.4 - 3.0 and 3.2 mm held
in an orderly fashion in a collet block. Carefully selected
material and targeted hardening contribute to a long
service life, while the triple slotting ensures maximum pre-
cision.
Our comprehensive and carefully compiled accessory
range provides you with a large selection of machining
tools of every kind. These can be found in our equipment
brochure or on the internet at www.proxxon.com.
We are confident that you will be impressed by the suc-
cessful machining results achieved and we hope you enjoy
using our compound table KT 70 CNC-ready or the
complete miller MF 70 CNC-ready!
