Flute and groove milling device and method for conductor cross section

The invention provides a flute and groove milling device and method for a conductor cross section, and relates to the fields of on-site flute and groove milling for conductor cross sections. The flute and groove milling device comprises a base, servo motors, rotary supports, sliding tables and long-neck motors. The servo motors are installed on the base. The rotary supports are round. The axial directions of the rotary supports are horizontally set, and the back faces of the rotary supports are installed on an installation plate. The installation plate moves in the axial directions of the rotary supports under the drive control of the servo motors. The sliding tables are installed on the front faces of the rotary supports. The long-neck motors are installed on the sliding tables. The middle of each rotary support is provided with a through hole allowing a conductor to penetrate therein, wherein the through hole is coaxial with the rotary support. The flute and groove milling device is simple in structure, nov
