Design of shaped cutter holder

Shaped cutter holders shall meet the following requirements:

The design of the holder must be simple and ensure the reliability and rigidity of the cutter attachment;

Quick pre-installation and precise adjustment of the height of the base point of the cutter blade along the height of the part axis is required;

For holders intended for different round shaped cutters with different height of cutter axis above part axis (universal holders) precise adjustment of this height is required;

For holders used on automatic machines, it is necessary to quickly and accurately set the base point of the cutter blade at the height of the part axis;

For holders of all types, it is necessary to align the dimensions of the holder with the dimensions of the working space and caliper of the machine used.
