Indexable Rotor Milling Cutter Series

Indexable Rotor Milling Cutter Series – Professional Solutions for High‑Efficiency Machining of Male and Female Screw Rotors

The Indexable Rotor Milling Cutter Series is a range of high‑efficiency specialized tools designed for machining male and female screw rotors in screw compressors, widely used in roughing, semi‑finishing, and finishing operations for air screw compressors and refrigeration screw compressors. With high technological content and complex design, this series consists of two cutters—one for the male rotor and one for the female rotor—corresponding respectively to the machining of the screw compressor’s male and female rotors. Featuring unique cutter body and insert designs, along with advanced substrate materials and coating technologies, this series delivers exceptional efficiency and reliability under both dry and wet machining conditions—making it the ideal choice for reducing production costs and improving machining efficiency in screw compressor rotor manufacturing.

Product Overview – High‑Efficiency Tools Purpose‑Built for Screw Rotor Machining

The core components of screw compressors (including air screw compressors and refrigeration screw compressors) are a pair of intermeshing male and female rotors. Traditional machining methods commonly use finger‑type milling cutters for roughing the rotor helical grooves, which suffer from low production efficiency and high tool consumption. The Indexable Rotor Milling Cutter Series fundamentally addresses these industry challenges as a dedicated high‑efficiency milling solution—through the segmented overlapping design of carbide indexable inserts, it precisely reproduces the screw rotor profile, ensuring uniform finishing allowance, significantly improving machining efficiency while substantially reducing tool consumption costs.

This series is suitable for dedicated machine tools as well as high‑power, high‑precision CNC machines, and has been widely applied and validated in the screw compressor industry both domestically and internationally.
