AI Technical Summary
Traditional grooving cutters lack length adjustment functionality, which leads to increased vibration during the cutting process, affecting surface quality and service life.
A high-strength slotted end mill was designed, which achieves length adjustment through a sliding sleeve and retaining post structure, and provides better length adjustment and vibration reduction by combining spring and spiral groove buffer design.
It effectively prevents the milling cutter from breaking due to excessive length, thus increasing its service life. Furthermore, the buffer structure reduces vibration and improves surface finish.
