The cutting head insert‘s design and control system
4. The cutting head insert‘s design and control system
Four cylinder screws are used to attach it directly onto the spindle in tail spindle or
slide units or else a mounting shank can be used in the chuck.
The cutting head’s installation dimensions can be found in the Installation Drawing
No. 00360216.
Drawing No. 00366546 shows you the control principle and the control paths.
Axial movement generated by the guide and eccentric rings opens and closes the
cutting head. The chamfers on the eccentric ring and the sliding blocks, which are
mounted on the chaser holders, convert the guide and eccentric ring’s axial move-
ment into the stinger bit’s radial movement.
A control box (not included in the package) is needed to transfer the clamping force
to the guide ring via a ball bearing. This can be either a ring or a fork design.
A dual-effect pneumatically or hydraulically operated cylinder can generate the ad-
justment movement, but you need to be able to control the speed and guarantee
even feed rates. The feed rate speed must be set up to match the raw material that
is being machined.
The required clamping force will depend on the durability of the material, the shape
and the size of the stinger bit and the toolpiece’s rotational speed. The following set-
tings can be used as a guideline:
Spindle rpm
(min-1) Clamping force
(N)
1000 400
2000 880
3000 1800
