Catalog excerpts

The BE 48-series is a flexible electro-pneumatic series of units in a modular design. The electric motor powers the spindle, while the feed is pneumatic. Hydraulic feed control makes it possible to include functions such as multiwall drilling, rapid advance and automatic chip removal. The series is available with JT2 taper or integrated ER32 chuck as well as with multi-spindle heads. • SMART DEPTH CONTROL Guidlines for choice of unit Min. Center to Center Spacing Single Spindle 90 mm Run-out at spindle nose (max.) 0.02 mm Depth accuracy +/- 0.01 mm Rapid advance rate (max.) 10 m/min Controlled feed rate >0.04 m/min Motor and Transmission specifications • Motor specifications shown in the tables are valid for 380-420V(Y) /220-240V(A) (±5%), 50 Hz. These motors can also be used at 440480 V(Y) (±5%), 60 Hz. If so the rpm will increase by ~20% and the power by ~15% relative to the data for 50Hz. E2 also offers 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
