1) High-precision manufacturing quality
In order to stably process the surface of high-precision parts, stricter requirements than ordinary tools are put forward for the manufacture of tools (including tool parts) in terms of accuracy, surface roughness, and geometric tolerances, especially indexable tools. The repeatability of the size of the insert tip (cutting edge) after indexing, the size and accuracy of the key parts such as the cutter body groove and positioning parts, and the surface roughness must be strictly guaranteed. And dimensional measurement, the base surface machining accuracy should also be guaranteed.
(2) Optimization of tool structure
The advanced tool structure can greatly improve the cutting efficiency. For example, high-speed steel CNC milling tools have adopted wave-shaped edges and large helix angle structures in structure. The replaceable and adjustable structure, such as the internal cooling structure, cannot be applied by ordinary machine tools.
