A circular knitting machine for knitted or hosiery items includes a supporting structure; a needle-holding cylinder selectively turnable around an axis of rotation of the knitting machine and provided with a plurality of cylinder needles; and a dial assembly arranged above the needle-holding cylinder. The dial assembly includes a supporting ring integral with the supporting structure; a needle-holding plate turnably mounted to the supporting ring and turnable around the axis of rotation; a plurality of plate needles; and a plurality of cams controlling the plate needles, which interact with the plate needles so as to transmit to them a radial movement inside the respective sliding seat based on a given law of motion, wherein the control cams globally form a cam profile defining the law of motion. The dial assembly further includes a stitch cam placed movably on the supporting ring and configured for interacting with the plate needles in a given angular sector during the rotation of the needle-holding plate, so as to transmit to the plate needles a motion of return for executing stitch formation. The stitch cam is selectively movable with respect to the cam profile.

A fine knitwear of circular knitting machines with air permeable holes is a single face fabric knitted via a circular knitting machine with knitting fineness 24 needles/inch. Each air permeable hole includes: at least one yarn located above the air permeable hole and formed via interactive movements of a Dial sinker and a plurality of latch needles perpendicular to the Dial sinker, and a first support loop and a second support loop that are formed via interactive movements of the Dial sinker and the latch needles and symmetrical against the yarn on the left side and the right side to support and tie the transferred yarn. The fine knitwear can meet market and consumers' requirements of providing more comfortable cooling, and the width of the air permeable holes can be changed flexibly in response to different requirements in the industry.
