Abstract
In a method of manufacturing a photoreceptor base drum by a lathe-turning machine in which a cutting tool is brought in contact with a surface of the base drum and travels in the axial direction to finish the surface of the base drum into a mirror-like surface, a main cutting edge formed by a rake surface and a front flank surface on the cutting tool is shaped as a curved surface with a radius of curvature of 0.15 to 3.5 .mu.m, and the rake surface and the front flank surface are shaped to smoothly continue to the curved surface of the main cutting edge.
Claims9
A method of finishing the surface of a photoreceptor base drum by using a lathe-turning machine, the method comprising the steps of:
- providing a cutting tool having a rake surface, a front flank surface, and a main cutting edge defined by at least a portion of the juncture of the rake surface and the front flank surface, the main cutting edge including a curved surface having a radius of curvature in the range of about 0.15 to 3.5 .mu.m;
- rotating the photoreceptor base drum on its axis in the lathe turning machine;
- positioning the curved surface of the main cutting edge into cutting engagement with the surface of the rotating photoreceptor base drum;
- and
- moving the engaged cutting tool in the axial direction of the rotating photoreceptor base drum for providing the surface of the photoreceptor base drum with a mirror-like finish.
