FINE BORING HEADS
SERIES 310 EWN/EWB APPLICATION INFORMATION Autobalance boring heads, Series 310 EWB, maintain perfect balance throughout the work range due to the integrated counter-balance mechanism. The counterweight can only compensate for one size insert holder, so the work range is similar to EWN heads with a Size 1 insert holder. Series 310 EWN boring heads are pre-balanced at one position only; the mid-range of the tool carrier travel with a Size 1 insert holder. Adjustment of the bore diameter from this position and/or use of Size 2 and 3 insert holders will require reduction of cutting speed values due to increased unbalance forces.
