Title: CUTTER HOLDER AND BASE SYSTEM FOR MILLING MACHINE
Abstract:
A cutter holder and base system for a milling machine, comprising a cutter holder (1) and a base (2). A hole-shaped internal area (21), a curved surface area (22), and a curved surface area (23) provided on the base (2). The curved surface area (22) and curved surface area (23) are provided in the peripheral region of the hole-shaped internal area (21) and are arranged at a certain angle (E6); the curved surface area (22) comprises a curved surface (22.1) and a curved surface (22.2); and the curved surface area (23) comprises a curved surface (23.1) and a curved surface (23.2). The cutter holder (1) is fitted with the base (2) by means of curved surfaces, so that the stress can be dispersed during cutting of a cutter, thereby prolonging the service life of the cutter holder and base system.
