Turret It is possible to install a wide range
of jigs from the simplest quick-acting
chucks (MultifixB, C including
Capto holders) through manually
controlled revolving turrets (Algra,
Parat) to the automatic control tool
head Sauter which allows for considerable saving of machining
process incidental times in tool
exchange during the machining
process. Accurately ground slideways The machine tool slideways form
part of the high-rigid cast-iron
monolith. There is the special friction
material film on the bed slide to
minimize the SLIP STICK effect,
whereby to achieve the high posi-
tioning accuracy of the working axes. Reliability and accuracy Positioning dynamics and accuracy of the working axes To achieve as maximum dynamics
and accuracy as possible each of the movable axes is equipped
with the actuating mechanism and
the preloaded ball screw ensuring
movable axis operating availability
to a maximum extent. comes out of basis and traditions of UHS machines manufactured in our company for several decades,
and it is supplemented by a series
of up-to-date engineering designs. >

Heat-balanced spindle The spindle has been imbedded in the bearings with oblique contact
in the front, and in the double-row
roller bearing NNK in the rear which
provides high accuracy, rigidity and
reliability of the spindle. SE 520 NUMERIC is the type of the machine tool designed for engineering production in medium and batch series or piece production. It has been designed for precision machining
of either simple or shape-sophisticated plastic and metal work pieces. The machine tool has
also been applicable as a teaching aid for both secondary schools and universities in the field
of engineering.
The machine tool has been operable in either the manual mode using the electronic wheels or, thanks to the up-to-date control system, in the automatic cycle. This creates new options in both piece and batch production. Constant output in all modes The high-power, digital-controlled adjustable-speed
motor with constant output of 11 kW assures spindle drive at a maximum of 2600 rev./min. Clamping system >

Speed and performance Reliability and accuracyPURPOSE

The work piece is clamped in the manually-operated jaw chuck.
It is possible to equip the machine
tool with the integrated pneumatic
jaw chuck by SMW Autoblock on
the customers demand, which will
considerably speed up chucking of the work piece. >
-1 . The two-speed belt drive transmits the torque to the spindle. Manual and digital control Җ the lathe is designed for either
manual operation (as a manually
operated centre lathe) or digital
control according to the work piece
shape and requirement after short
training of the operator to achieve
high accuracy and higher produc-
tivity repeating. Spindle revolutions >

Versatility/Complexity

The continuous electronic spindle
speed adjustment and feed rate
ensures constant cutting speed
within the selected speed step,
which responds to the question
how to achieve superior surface
and minimize miscellaneous time. Machine design The machine design makes pos-
sible production of the lathe in various versions within the wide
range of accessories to meet the
users requirements, which allows
for optimal possibilities for complete
machining of shaft and flange work
pieces. >
