摘要： PURPOSE: To improve the quality of milling by curving a cutting face and a flank. CONSTITUTION: A cutting edge 22 is formed between a cutting face 25 and a flank 24 of an insert 21, which are continuously curved. Thus an insert rake angle and a clearance angle which are prescribed about a cylindrical holder are made invariable along the length of the cutting edge, and a machined face obtained using an outer periphery rotary type milling cutter composed by detachably attaching the insert 21 to the outer periphery of the cylindrical holder can be smoothed, and its machining accuracy can be improved.

摘要： PROBLEM TO BE SOLVED: To fix an adaptor positively to a tool shank by forming at least a part of a through hole, disposed in a protrusion, into a tapered state toward the contact face of the protrusion of an adaptor fitting part. SOLUTION: A protrusion 20 of an adaptor is led into a recess of a tool shank 1, and clamp screw 4 is inserted in a through hole 26 of an adaptor fitting part. This screw part is screwd into a threaded hole 38 of a holding part of the shank 1 to grip. When the screw 4 is fastened, tension generated by this fastening presses a conical screw head 5 inward to a taper part 28 of the through hole 26 so as to enlarge the adapter fitting part 26 in the recess and to press the upper and lower holding faces 23, 24 of the protrusion 20 to the upper and lower holding faces of the recess.

摘要： PURPOSE: To facilitate improvement in efficiency of metal removal from a workpiece by tilting a second cutting edge portion towards the base of an insert, crossing a rotary spindle substantially, and merging with an adjacent cutting edge of a first pair via a coupling portion which tilts away from the insert base. CONSTITUTION: A transverse cutting edge 6 merges with the rounded corner 16 via an initial cutting edge portion 6a nearly parallel to a base 12 of an insert. The portion 6a is followed by a cutting edge portion 6b tilting toward the base 12 downwardly, and by a cutting edge part 6c prescribing an substantially obtuse angle to a leading portion and tilting toward the base 12 more steeply. The cutting edge part 6c merges with the lowest cutting edge portion 6d crossing the rotary spindle 8 of a cutting insert substantially followed by a coupling portion 6e tilting from the base 12 so as to merge with an adjacent main cutting edge 5.

摘要： PURPOSE: To reduce chattering by shortening a component cutting edge very much. CONSTITUTION: A cutting edge 17 is furnished with a plural number of intermittent component cutting edges 17a-17c and intermediate edges 19 respectively positioned between these intermittent component cutting edges 17a-17c. Each of perpendiculars to an axis of rotation of a cutting tool passing through rear end parts of these component cutting edges crosses the intermittent component cutting edges in such a way that the intermittent component cutting edges are partially accumulated on each other during milling work. Consequently, a chip is formed by the short cutting edge, force of a result influenced by a cutting insert is comparatively weak, and chattering is minimized.

摘要： PURPOSE: To improve the service life of the subject tool by sintering a mixture composed of a specified weight percents of α alumina having a hexagonal crystal structure and a specified weight percents of titanium carbonitride(TiCN) composed of titanium carbide and titanium nitride. CONSTITUTION: Though in the case of 80 wt.% of alumina and 20 wt.% of titanium carbonitride a longest service life is show, and there is a trouble, in the case of 70 wt.% of alumina and 30 wt.% of titanium carbonitride a longer service life is shown and there is less trouble. A composition of the material for the subject tool comprises 60-80 wt.% of alumina and 20-40 wt.% of titanium carbonitride composed of 30-50 wt.% of titanium carbide and 30-70 wt.% of titanium nitride. Furthermore, a composition comprising titanium carbonitride composed of 30-50 wt.% of titanium carbide and 50-70 wt.% of titanium nitride and a composition comprising 70 wt.% of alumina and 30 wt.% of titanium carbonitride are used. The compositions are sintered to provide the subject tool.
