Abstract: The present invention relates to a circular knitting machine not requiring a net cylinder. More specifically, a knitting needle groove is formed so that a knitting needle is directly recessed in a cylinder and dial of the circular knitting machine, so that it is not required to combine the cylinder and the dial with a net cylinder, thereby decreasing work tolerance and increasing due to direct cutting of the cylinder and dial body of the circular knitting machine. In addition, since the knitting needle moves by being recessed in the grooves of the cylinder and dial body, movement and separation of the knitting needle can be reduced. In addition, gaps and unnecessary assembly processes caused by assembling the net cylinder are eliminated, thereby increasing productivity.
