GESADUR® WN - Processing hints

Turning

    • Use only carbide tools
    • K10, lead angle to work ~ 5°
    • Rake angle 0 - 10°
    • v = 200 - 250 m/min
    • First rough-turn and/or finish turning parts
    • s rough turning ~ 0,25 - 0,5 mm/rev
    • s smoothing < 0,15mm/rev.
    • Select a cutting edge angle of 45° where possible

p

When turning workpieces whose exit side has already been finally planed, take these with the minor cutting edge of the turning chisel and then re-turn only when ready. This prevents the workpiece from breaking out on the exit side.

Superfinish of running surfaces

To ensure first-rate surface quality, a feed motion of 0.03 mm / rev. should be selected for superfinishing. Best surface quality is achieved by diamond cutting.

Drilling

Using only carbide-tipped twist or flat drills on the drill press, cutting angle ~ 90°, v = 40 m / min, drilling with SS spiral drill v = 15 - 20 m / min.
Clear chips regularly when using a twist drill.
