Abstract

An automatic lathe or miller for machining the spirally curved surface is composed of mainshaft box, mainshaft, chuck, machine frame, tailstock, center on the axle of tailstock, and milling tool driving unit consisting of X,Y and Z slide benches and electric mainshaft. Its machining technology includes such steps as milling reference surface, milling for shaping, refining and tempering.

Description

technical field [0001] The invention belongs to mechanical cutting processing technology, in particular to a turning and milling device and processing method for an outer spiral space curved surface. Background technique [0002] At present, ordinary milling machines or CNC milling machines are usually used to mill and process multiple spatial helical surfaces on the outer surface of rotary parts. This processing method not only has low production efficiency, but also requires high dimensional accuracy, shape accuracy, and spatial position accuracy of helical surfaces , it is difficult to guarantee product quality, and the yield is low. Therefore, it is very necessary to study a method of replacing milling with turning and milling, which has simple processing technology, high production efficiency, low production cost, and can ensure processing accuracy. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems in the proce...
