Preparation process of friction welding milling cutter

The invention discloses a friction welding milling cutter preparation process which comprises the steps of raw material treatment, welding, pretreatment, primary treatment, secondary treatment, head preparation, film coating and the like, raw materials are divided into batches according to handle diameters, the raw materials with similar handle diameters in the same batch are selected as handle materials and head materials, and the head materials and the handle materials are coaxially welded in a friction welding mode. And through automatic segment difference, semi-finished product detection and multiple times of centerless grinding, the handle material side is ground to meet the product requirement, then the head is prepared, finally, film coating is conducted, the product performance is improved, the preparation effect is good, the milling cutter strength is high, unsoldering is avoided in the vacuum film coating environment, and stability is good. 本发明公开了一种摩擦焊铣刀制备工艺，包括原材料处理、焊接、预处理、一次处理、二次处理、头部制备、镀膜等步骤，将原材料根
