How is the worm spiral surface of the reducer processed?

 The spiral surface of the worm of the reducer is processed by a straight blade car, a plane grinding wheel, an angle milling cutter and a tapered grinding wheel which is easy to manufacture.

The tool is mounted on the rotary tool holder, and the axis of rotation of the tool holder is staggered with the axis of the worm. The straight blade of the tool car or the straight generatrix of the milling car and the grinding wheel should be tangent to the main base circle of the worm wheel, and coincide or tangent to the worm tooth profile.When the worm rotates, the tool holder rotates according to the speed ratio i1d, the track curved surface of the linear blade on the worm, and the envelope surface of the plane or cone is the spiral surface of the toroidal worm.
