Description

Universal externally-tangent cyclone milling head

Technical Field

The utility model belongs to the technical field of milling head equipment for the whirlwind mills, concretely relates to circumscribed whirlwind milling head of omnipotent formula.

Background

The cyclone milling is a high-speed thread milling device matched with a common lathe. A thread machining method for milling thread from workpiece by using hard alloy forming cutter installed on high-speed rotary cutter head. Because the milling speed is high (the speed reaches 400m/min), the machining efficiency is high, and compressed air is adopted for chip removal and cooling. The cutting splash such as whirlwind in the processing process is called as whirlwind milling; the cyclone milling machine can realize dry cutting, heavy-load cutting, difficult-to-machine materials and ultrahigh-speed cutting, and has low power consumption. The surface roughness can reach Ra0.8 mu m. The lathe spindle has low rotating speed, so the lathe has high motion precision and good dynamic stability, and is an advanced thread machining method; the angle of a spindle of the existing externally tangent cyclone milling head cannot be adjusted, the section requirement during thread turning cannot be met, and the function is single during use.
