Suhner Industrial Products (Rome, Georgia) recently introduced its machining unit BEX 15 with maximum spindle speed up to 23,000 rpm, thus offering higher speeds and improved production inline. Standard variations are equipped with electric motors of 0.55 kW, 0.75 kW and 1.5 kW. An adapter flange is designed for the installation of multiple spindle heads and angle heads.
A new style timing belt drive multiplies the motor speed up to 13,050 rpm spindle speed. An AC inverter drive is used to increase the spindle speed up to 23,000 rpm at 87 Hz. Standard motor mounting on BEX 15 machining spindles is in the rear. Optional front motor mounting is available upon request.
Additional optional features include frequency converter and direct drive servomotor.
The machining unit BEX 15 can be applied in axial and radial orientation, directly mounted to a Suhner linear slide assembly Type UA15-PH or UA15-CNC. In this combination, numerous operations such as milling or demanding drilling cycles including jump or peck feed can be accomplished easily.
Four optional toolholder systems (Collet ER25, ISO30, HSK50 and Weldon), standard air purge connections for spindle and belt housing including a number of additional options (for example, coolant through the spindle or automated tool change features) make this machining unit type BEX 15 adaptable and an optimal choice for demanding and specific inline machining requirements. BEX 15 with HSK spindle includes an integrated 4-point clamping system form C, for manual tool clamping.
