Structure and principle of micro - hole machining of melt - spraying cloth spinneret
The machine tool USES the principle of edM spinneret to produce high-precision, high-finish precision microholes. It is used for processing precise microholes of various types of injector parts. The range of precision circular microholes is generally within ￠0.1~￠0.5mm. The machine is made of round slender wire electronic spinneret. The servo feed and loss compensation of spinneret are realized by using the refeed mechanism with slender wire electrode. Deionized water working liquid is generally used for processing. The machine consists of a main engine, an electric control box and a working fluid system. The electric control box is composed of industrial control machine, high frequency pulse power supply for micro finishing machining, servo control unit and electrical components of machine tool.
Puncher spinneret special purpose machine tool machine adopts round slender wire electrode. The servo feed and loss compensation of electrode in machining are realized by refeeding mechanism with slender wire electrode. Deionized water working liquid is generally used for processing.
Ii. Structure of melt spraying cloth spinneret
The structure of spinneret can be divided into three forms according to the shape of spinneret, namely, cause, fan and rectangle. At present, there are more circular and rectangular spinneret in domestic and abroad. In order to suit the spinning occasions of different kinds of chemical fiber, circular spinnerets can be divided into flat spinnerets, convex spinnerets, circular spinnerets, etc. Rectangular spinnerets can be divided into flanged rectangles and flanged grooved rectangles, etc., which are mainly used for staple fiber spinning with more holes.
