Title:
CUTTING TOOL
Document Type and Number:
Japanese Patent JPS59205205
Kind Code:
A
Abstract:

PURPOSE: To reduce cutting resistance at work cutting while cancelling out said resistance with each other and to economize in energy at that time by providing respective blade parts oppositely inclined with each other on the tips of one or more shanks provided on a cutter holder.

CONSTITUTION: Two shanks 2 are removably attached to a cutter holder 1 by a machine tool such as a working lathe by means of mounting bolts 3, and each of blade parts 4a, 4b oppositely inclined with each other is provided on each tip part of each shank 2. And, the infeed of this blade part 4a for rough machining going ahead in the feed direction is formed shorter than that of the blade part 4b for finishing going behind. Accordingly, feed components Fr, F1 by respective blade parts 4a, 4b cancel out with each other and reduced, and thus cutting resistance is also reduced, enabling energy saving to be realized with a simple operation.
