Abstract:
A method of improving working of grooves of a screw rotor, in particular, working of grooves side in working efficiency, a working apparatus, a working tool, and a method of manufacturing a screw compressor are provided. A method of controlling rotation of a work and turning of a tool at a time to form a screw tooth space based on a five-axis NC machine, and a special end mill having a cutting edge of a short length and a neck portion provided between the cutting edge and a shank portion to be made thin is used to perform working in grooves side finish working process.
