Cutting Insert Recess Mounting for Stable Profile Turning

The clamping system is segmented into multiple independent bearing surfaces (first, second, third bearing surfaces) that distribute clamping forces across different contact points. This segmentation prevents relative movement by creating multiple constraint points between the cutting insert and tool holder, thereby improving machining quality and stability.

Multiple bearing surfaces are merged into a unified clamping structure where the first, second, and third bearing surfaces work together as an integrated system. This merging creates a stable insert seat that eliminates relative movements during machining operations.

The cutting insert is reoriented from a vertical arrangement to a horizontal arrangement on the tool holder. This dimensional change allows large cutting widths to be achieved without increasing the insert's height in the vertical direction, thereby reducing carbide consumption while maintaining cutting capacity.

The orientation parameter of the cutting insert is changed from vertical to horizontal positioning. This parameter change enables the same cutting width capacity to be achieved with reduced material consumption, as the insert utilizes its surface area more efficiently in the horizontal plane.

The clamping interface is segmented into multiple bearing surfaces distributed across the horizontal insert structure. This segmentation provides sufficient clamping stability in the constrained space of internal bore machining by creating multiple contact points that distribute mechanical loads effectively.

The horizontal cutting insert design with multiple bearing surfaces serves multiple functions: it reduces the vertical profile for confined bore machining spaces while simultaneously providing stable clamping through distributed contact surfaces. This multi-functionality resolves the contradiction between space reduction and stability maintenance.
