20120251253 | CUTTING TOOL - Disclosed is a cutting tool, including: a cutting edge including a coating from a rake face to a flank face, and has a relief angle of not less than 15 degrees, a material of the coating having a higher wear resistance than a base material of the cutting edge, and during cutting of a work, an edge of the coating on the rake face at a top of the cutting edge is worn by friction with the work; with a progress of a wear inward in a radial direction, an edge of the coating on the flank face at the top of the cutting edge is removed by friction with the work to expose the base material thereunder; and the exposed base material is worn by friction with the work to retract the flank face inward in the radial direction. | 10-04-2012 |
20120321403 | DRILL BIT - Provided is a step-shaped drill bit including at least two stepped cutting edges that are axially provided. A cutting edge of a first step from a tip is formed so as to satisfy at least one of the following conditions. That is, a number of blades is smaller, a point angle of the cutting edge is larger, or a clearance angle of the cutting edge is larger than that of cutting edges of a second and subsequent step(s). As a result, a thrust resistance during a perforation can be reduced compared with a case in which the first step cutting edge is formed such that the number of blades, the point angle of the cutting edge and the clearance angle of the cutting edge are the same as those of the second and subsequent step(s). | 12-20-2012 |

20140054053 | TOOL DRIVING DEVICE, TOOL DRIVING METHOD, AND TOOL FEEDING MECHANISM FOR TOOL DRIVING DEVICE - A tool feeding mechanism for a tool driving device includes a cylinder mechanism, a positioning mechanism, and a holding mechanism. The cylinder mechanism moves a tool rotation driving device to hold and rotate a tool, in a tool axis direction on an exterior of a cylinder tube using power of a piston. The positioning mechanism is connected to the cylinder tube side of the cylinder mechanism either directly or indirectly in order to position the cylinder mechanism relative to a workpiece. The holding mechanism holds the tool rotation driving device such that the power of the piston in the cylinder mechanism is transmitted to the tool rotation driving device. | 02-27-2014 |
