The accuracy requirements of sewing machines' parts size are high, the tolerance range of the size is small, after the turning of traditional equipment, but also add a number of grinding processes to reach the surface size.
In addition, many small parts in the sewing mechanical shell, not the general plane, but curvature, spherical, must cut out the suitable surface in order to be suitable for mechanical action with special angles.
Its surface can be measured and designed by computer, but the actual processing is not the general processing equipment which can be competent, it must be precisely carried out by CNC lathe, CNC processing center, there is no other way to save production costs.
Our sewing machines are capable of achieving high component accuracy.
