Tools for high speed cutting
Item no. 10303123, Revision 09 31 ( 40 )
11 Tools for high speed cutting
DANGER: Due to flying parts.
If the wrong direction of rotation is used, the tool is damaged when load is
applied. The centrifugal forces cause the broken part to be flung out.
u
Only use tools with the correct direction of rotation for the HF spindle.
DANGER: Due to flying parts.
If the speed is selected incorrectly, the HF spindle or the tool may be de-
stroyed and their fragments may be flung out.
u Note the maximum speed for the selected tool.
u
Note the maximum speed for the HF spindle.
u The maximum permissible speed of the HF spindle for commissioning /
processing is always the
lowest specified speed.
Ü Only use tools that are technically sound.
Ü Only use tools with a tool shank diameter that corresponds to the inner di-
ameter of the collet. For example, do not use shanks with a diameter of 3
mm in collets for 1/8” (=3.175 mm).
Ä Also see the Technical Specifications [
}
14] section
Ü Only use tool shanks with a diameter tolerance of h6.
Ü Do not use tool shanks with a clamping surface (e.g. Weldon).
Ü
Only use a balanced tool.
