Electric pneumatic BEG48
Electro Pneumatic Tapping Unit BEG48
The BEG 48-series is a flexible electro-pneumatic unit in a modular design. The electric motor runs the spindle, while the feed is pneumatic. Hydraulic feed control makes it possible to use rapid advance and to adjust the feed rate in proportion to the pitch and the rpm. A tapping collect or a tapping spindle gives the unit the necessary length compensation. The series is available with JT2 taper or integrated ER32 chuck as well as with multi-spindle heads.
• Compact yet flexible design
• Modular hydraulic feed control for the whole stroke
• Smart depth control
• Linear transducer for total control of the complete cycle (optional)

We do not recommend floating tapping at turns over 2000 U / min. use. In addition, we point out that the max. speed
when cutting reduced in deep holes, blind holes or the use of larger threaded heads.
• Motor specifications shown in the tables are valid for 380-420V (Y)/220-240V (Δ) (±5%), 50Hz. These motors can also
be used at 440-480V (Y) (±5%), 60 Hz. If so the rpm will increase by ~20% and the power by 15% relative to the data
for 50Hz. We also offer motors for other voltages and frequencies. Please state voltage and frequency when requesting
a quote or ordering.
• the torque at the spindle for a specific rpm is calculated as:
M = (P[kW] x 9500) / rpm
