DELIVERING HIGH TECHNOLOGY
New motor spindle technology
100% Swiss design and manufacture

by Tornos in Moutier, Switzerland.
Identical main spindle and counter spindle with

high performance synchronous motors.
Heat exchanger keeps the spindles thermally

stable assuring high precision.
Powered spindles offer high output and high

torque.
Reduction in idle time (stopping, indexing,

acceleration, deceleration), from 0 to
10 000 rpm in 0,9 sec.
Reduced noise and maintenance.

Best power in its class.

Working with or without a guide bush
Possible to switch between the guide-bush

type and guide-bushless type, the most suitable
system for the part can be choosen.
Quick change over in less than 30 min.

Lower quality bar material required and shorter

bar end (short bar remnant).
«Done in one»
For example :
Finish the part! This has been the challenge

EXTREME MACHINING CAPABILITIES
Ergonomics
The wide machining area enables the operator
to access the tools easily for short setup times.
User friendly thanks to the latest Fanuc control,
embedded in an ergonomic panel, and mounted
on a swivelling arm that can be accessed from
both sides of the machine.
Un-manned operation
To improve the machine’s profitability, the Swiss
ST 26 has been designed to run unattended for
long periods of time with no human intervention.
