This machine is able to achieve high quality sewing even at its highest speed of 4200rpm. Thanks to the adoptin of new type thread trimming mechanism, it is no longer required to snip off the end of thread. The feeding and needle bar mechanisms are driven by a stepping-motor capable of analyzing as precise as 0.05mm, which ensures beautiful and quality seam. By setting the sewing speed of the first 5 stitches on the control panel, the machine starts working at low speed, which can largely prevent thread breakage and fraying at te beginning of sewing.
