Title:
GEAR FORMATION CUTTER
Document Type and Number:
Japanese Patent JP3935914
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a small gear formation cutter capable of forming a gear tooth on a non-metallic precision apparatus.
SOLUTION: A blade part 20 extends along an axis X of a spindle 10 from a cross-section of the spindle 10. The blade part 20 has a blade surface 21 and a peripheral surface 22. The blade surface 21 has a front side 211 and a rear side 212 and has a first side 213 and a second side 214 facing to each other. The first side 213 has a form corresponding to an outline of a side surface of the gear tooth. The peripheral surface 22 is arranged around the axis X and extends to the second side from the first side. Any point on the first side is separated from the axis by a second radial distance. Any point on the second side is separated from the axis by a second radial distance. The second radial distance is smaller than the corresponding first radial distance. The first radial distance to which the rear side corresponds is larger than the first radial distance to which the front side corresponds.
