Abstract

The invention of a circulator and manufacturing method thereof is applied to a circulator which is in the rectilinear motion bearing. It comprises the following steps: medium forming: to select well-lubricated substance (such as wax etc.) and macromolecule material (such as PE, PP etc.) etc, to add necessary amount of the binding material, then to stir and mix, and to shape form by injection molding from a mold; medium positioning: to put the forming medium into the mold of the circulator; MIM forming (metal injection molding): to inject metal powder from the mold of the circulator and make the medium wrapped to become the rough pattern; defatting: to remove the binding material in the rough pattern; sintering: to form the defatted rough pattern in high temperature, and to burn out the residue of the binding material and the spiral curve cylinder of the medium. Then a finished product of the circulator is produced after cooling process able to be inlayed in the rectilinear motion bearing to provide good circulate effect for the steel ball. Wherein the invention of the circulator is sintered by injection molding of metal powder to become a unity body comprising a base having guide rail for rolling balls arranged in the same direction tilted from right to left, and a tongue piece set on the guide rail. Besides a raised portion for fixing position formed by two oblique angles of the base can exactly put in the spiral groove of the ball screw, wherein the guide rail for rolling balls is arranged in a way perfectly matching with the screw groove to achieve the purpose of the invention.
