Catalog excerpts
BE 55 is a powerful yet compact electro-hydraulic series of units. The electric motor runs the spindle while the feed is hydraulically powered and controlled. The hydraulic feed control together with position switches makes it possible to include functions such as multi-wall drilling, rapid advance and automatic chip removal. The units are available in two different taper options as well as with multi-spindle heads. • IDEAL FOR FLOW DRILLING • HIGH PRECISION Guidlines for choice of unit DRILLING UNIT Thrust (max.) Stroke (max. 100% controlled) Min. Center to Center Spacing Single Spindle 140 mm Run-out at spindle nose (max.) Rapid advance rate (max.) 6 m/min Controlled feed rate 0.04-0.65 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 440-480 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
