Friction coefficients
With workpieces made from a material other than steel, mul-
tiply these values by the correction values listed below.
When the workpiece is made of hardened steel, the values
for smooth clamping heads always apply to ground work-
piece surfaces.
NOTE
Damage to materials caused by using the wrong
clamping head when clamping hardened materi-
als!
 For the clamping of hardened materials, or of
high-tensile materials

, the only
permitted clamping heads are smooth with longi-
tudinal and transverse serrations!

Other versions of clamping head may get dam-
aged and lose their ability to achieve higher fric-
tion coefficients on soft materials.
