High-speed spindle for challenging machining applications
The PreciMill is equipped with a tailor-made Fischer high-frequency spindle
featuring an HSK-E25 tool interface, reaching speeds of up to 50,000 rpm. The
spindle includes a rotary union for high-pressure cooling through spindle at up to
120 bar, optimizing drilling speed, machining quality, and tool life.
It also features a stop block for locking turning tools, an axial thermal expansion
sensor, and an anti-static brush, ensuring maximum precision.
Mechanical concept and machining area
A high-performance design for uncompromising precision
The design of the PreciMill machining center guarantees excellent precision and outstanding dynamics. Its mechanical structure has been carefully studied to achieve an optimum balance between static mass, which ensures a rigid and stable base for maximum precision, and moving mass, optimized thanks to a honeycomb cast-iron design, which considerably improves the machine’s responsiveness and dynamic performances.
The precision and repeatability of the PreciMill machining center are also guaranteed by its axis system, equipped with direct-drive linear and torque motors. The axes are thermally regulated to minimize expansion and are equipped with optical encoders. Strokes of 180 x 140 x 160 mm enable machining of mechanical parts up to 120 x120 x 120 mm.

PreciMill is compatible with industry-standard milling and drilling tool holders
For turning, the tool holders are specific. They are indexed and locked using a stopblock mounted under the spindle housing.
PreciMill features a laser tool measurement system to guarantee high machining accuracy and consistent process repeatability.
Equipped with a doublegripper rotary arm, the changer system enables rapid and accurate tool exchanges.
Circularity XY R10mm
Circularity tests show PreciMill’s excellent dynamic behaviour.
