Precision and reliability
The drill heads are driven by a splined shaft. This drive guarantees constant power transmission and thus avoids
drill bit breakage. The drill heads can be moved and re-positioned on the shaft easily and quickly.
The stroke movement on Dürselen paper drilling machines is done by a motorised precison cam. This feature
ensures a constant stroke movement - which is also essential to avoid breaking of drill bits -
and the cam reverses the stroke at bottom dead centre precisely.
For economic drilling of low piles the Dürselen paper drills feature the short stroke movement. Instead of
returning to the top position the drill beam just leaves the pile and performs the next stroke from this lowered
position. Specially when drilling multi-hole patterns for mechanical binding this function increases the output
drastically.
