ADVANTAGES
HOW TO BENEFFIT FROM SIGMA FLEXI VERTICAL MACHINING CENTERS
Maximum precision
The movable work table on the Sigma Flexi vertical machining center that travels along the X-axis enables top workpiece precision and quality. Precision and position repeatability is increased even further by automatic compensation for temperature drifts on the spindle and linear axes using sophisticated sensors.
Top performance
Motor spindles developed in-house ensure the highest performance (33 kW), torque (235 Nm) and speed (19,000 rpm) with a long service life. The machine's structural design permits outstanding strength for extreme utilization of its spindle's power and torque.
Ideal yield rates
The tool magazines on a Sigma Flexi vertical machining center are structurally independent of machine movements. This enables tools on the chain to be easily and safely checked and replaced without interrupting the machining cycle.
Safe tool changing
Sigma Tool Check, an electronic device near the tool loading and unloading system, permits the tool magazine and tools to be fetched, assigned and managed. Direct connection with the CNC controls ensures uninterrupted machining cycles.
