Khushbu engineers offers the sine table for angular machining, grinding, boring or inspection. It consists of a cast iron base and hinged top plate to the base. The top plate has t-slots provided to clamp the job. The base plate consists a hard wear plate on which the half round pin of the top plate rests. The center distance between the hinge pin and the slip gauge resting pin is precisely controlled to a known dimension. The required angle is derived from deciding the height of the calculated by the pythagoras principle.
