CUTTING TOOL WITH ASYMMETRIC STRUCTURES ON CUTTING TEETH

摘要

A cutting tool with asymmetric structures on cutting teeth has multiple toothed surfaces. Each of the toothed surfaces has multiple groove structures dividing a side edge of the toothed surface into the cutting teeth. Since the groove structures of the toothed surfaces are arranged in an asymmetric and complementary manner, contact areas between the cutting teeth on the toothed surfaces of the cutting tool and a workpiece are reduced. The cutting teeth on the toothed surfaces of the cutting tool are not worn and broken easily. When the cutting tool is used for cutting hard brittle material, machining quality, accuracy, and efficiency are enhanced.

主权项

1. A cutting tool comprising:
an end portion; a side surface; a tool tip axially formed on the end portion; and multiple toothed surfaces formed on the end portion and separately arranged around the tool tip, each of the toothed surfaces extending between the tool tip and the side surface and having
a side edge;an inner end connected to the tool tip;an outer end connected to the side surface; andmultiple groove structures formed in the toothed surface, separately arranged between the inner end and the outer end of the toothed surface, formed through the side edge of the toothed surface, and dividing the side edge of the toothed surface into multiple cutting teeth, the groove structures being equidistantly spaced; wherein the cutting teeth of one of the toothed surfaces are respectively positioned toward the groove structures of the other one of the toothed surfaces; and the groove structures of the toothed surfaces are arranged in an asymmetric and complementary manner.
