Suhner introduces a redesigned version of its BEX15 machining unit, increasing spindle speed from 18,000 to 23,000 rpm for applications like small-diameter hole drilling or cutting metals with high cutting speed requirements. The spindle speed improvement is the result of a complete redesign of drive and spindle bearing components. A different style of timing belt drive increases the spindle motor speed to 13,050 rpm, and an AC inverter drive multiplies the spindle speed to 23,000 rpm at 87 Hz. The machining unit can be applied in axial or radial orientation, directly mounted to a Suhner slide-assembly-type UA15-PH or UA15-CNC. The unit can perform milling or demanding jump- or peck-feed drilling cycles when configured EDJ Grooving in this way, the company says.

The unit includes four optional toolholder systems (collet ER25, ISO-30, HSK-50 and Weldon) as well as standard air purge connections for Surface Milling Inserts spindle and belt housing. Additional options such as through-coolant and automatic tool-change features are also available.
