Tips for Paper Drilling
Your Dürselen Paper Drill can process many different materials in perfect quality. Following a summary of our experience. There are some pre-conditions for clean results and to avoid drill bit breakage:
- strong, solid paper drilling machine which ensures straight-lined and rectangular drill stroke movement
- continuously variable stroke and spindle speed control
- constant power transmission through the whole drill stroke
- high-quality and sharp drill bits with interior diameter polished as smooth as possible
- true running spindles (no wobbling)
- drill bit cooling and lubrication
Basic rules for different applications:
- small diameters -> higher revolutions, large diameters -> lower revolutions
- strong material / high grammage -> slower stroke speed, thin materials / low grammage -> higher stroke speed
- If the speeds are well chosen and the results are still not satisfactory it is usually helpful to reduce the pile height
