摘要： PURPOSE:To aim at improvement in abrasion resistance of a cutting tool, by forming a quenching congealment layer rich in a celllike congealing structure in a cutting edge. CONSTITUTION:A quenching congealment layer 2 to be formed in a cutting edge predetermined part of high speed steel 1 by means of irradiation of a laser beam is roughly constituted of a dendrite structure part 3 being grown along a congealing progress direction and a celllike structure part 4 by homogeneous core formation. And, it is machined so as to cause this celllike congealing structure 4 to come to a cutting edge. Since a side of the celllike congealing structure part is more excellent in abrasion resistance than the dendrite congealing structure part, a suchlike cutting edge part is formed in the celllike structure part 4, whereby it can be made into such one that is very excellent in the abrasion resistance.

摘要： PURPOSE:To obtain excellent finished surface roughness by forming a quick- coagulation layer with a secondary dendrite space of 6 mum or less on an addendum section made of high-speed steel of a cutting tool. CONSTITUTION: A quick-coagulation layer 1 is formed by being coagulated from a liquid phase at a cooling speed of about 600 deg.C/sec or more, and the secondary dendrite space becomes 6 mum or less under such high-speed cooling. Concurrently, the second layer grain of a carbide or the like becomes about 1 mum or less. For example, a beam is illuminated from the direction of a flank 3 after the rough machining of an addendum 2 to perform the finish machining of the addendum 2. The addendum 2 is tempered after beam illumination and is machined so that the quick-coagulation layer about 0.1 mm or more in width is formed from the addendum 2 to the flank 3 and a rake face 4. The flank width X and rake face width Y are made about 0.1 mm or more. Accordingly, high-precision finished surface roughness can be improved.

摘要： PURPOSE: To prevent deformation by a heat treatment in the stage of heat- treating a metallic plate, etc., by the irradiation of the laser beams from both faces thereof by controlling the deviation in the irradiation position of the laser beams, the difference in the beam outputs and the difference in the spot shapes of the beams within a specific range.
CONSTITUTION: The laser beams 2a, 2b of the outputs Wa, Wb are irradiated to both faces 1a, 1b of a plate material 1 to be treated such as metallic plate to heat-treat said material. The deviation D of the irradiation positions 3a, 3b of the two laser beams 2a, b is controlled within 20% of the spot length La of the laser beam 2a or 2b; i.e., D/La≤0.2. The difference between the output Wa, Wb of the two laser beams is controlled within 10% of the output Wa or Wb, i.e., (Wb-Wa)/Wa≤0.1. The difference between the spot shapes Lc, Ld of the laser beams 2a, 2b is controlled within 20% of Lc or Ld, i.e., (Ld-Lc)/ Lc≤0.20. A cooling gas such as He or Ar or liquid nitrogen is sprayed like mists 4a, 4b to the parts except the positions 3a, 3b to cool the material. The generation of thermal deformation such as camber or bend of the material 1 heat-treated by the laser beams is thus prevented.

摘要翻译：目的：通过控制激光束的照射位置的偏差，通过从其两个面照射激光，在金属板等的热处理阶段通过热处理来防止变形，光束输出和光束在特定范围内的光斑形状的差异。构成：将输出Wa，Wb的激光束2a，2b照射到金属板等被处理板材1的两面1a，1b，对该材料进行热处理。两个激光束2a，b的照射位置3a，3b的偏差D被控制在激光束2a或2b的光点长度La的20％以内; 即D / La <= 0.2。两个激光束的输出Wa，Wb的差被控制在输出Wa或Wb的10％内，即（Wb-Wa）/ Wa <= 0.1。激光束2a，2b的点形状Lc，Ld之间的差被控制在Lc或Ld的20％内，即（Ld-Lc）/ Lc <0.20。将诸如He或Ar或液氮的冷却气体像雾4a，4b一样喷射到除3a，3b之外的部分以冷却材料。因此防止了由激光束热处理的材料1的热变形（如弯曲或弯曲）的产生。
