摘要： Provided is a rotary cutting tool that can increase the overall flexural rigidity of blades used therein, even with blades having small thicknesses. A cutter head for woodworking has fitting grooves formed at circumferential four positions on an outer peripheral side of a body. The fitting groove is curved in small measure in an arc shape in a direction opposite to a direction of rotation of the body. The fitting groove is symmetric on both sides of the body. The fitting grooves are each mounted with a blade and a wedge bar. The blade is a long and thin plate having a nearly rectangular shape and elastically deformable. The blade is made of a steel material or a cemented carbide and about 0.5 mm in thickness. The blade is curved in an arc shape that corresponds to the shape of the fitting groove in a direction opposite to a direction of rotation R and then fixated in the curved state. A twist angle representing an angle of inclination of a cutting edge in each blade from a shaft center on an outer peripheral surface of the body is a negative twist angle that changes in a curve on the side of one end surface of the body but is a positive twist angle that changes in a curve on the side of the other end surface of the body.

摘要： Provided is a wood cutting tool with improved wear resistance and corrosion resistance. A hard fundamental layer (18) of chromium nitride (CrN) is subjected to PVD to be coated on a rake face (16) of a substrate (12) formed of a cemented carbide alloy or a tool steel. The hard fundamental layer (18) has a five-layer structure having a first layer (18a) to a fifth layer (18e) disposed in order from the substrate (12) side. A hard main layer (20) of chromium oxide (Cr 2 O 3 ) is coated on the outer surface of the fifth layer (18e) of the hard fundamental layer (18). The hard main layer (20), like the hard fundamental layer (18), is formed by PVD. The hard fundamental layer (18) is coated with the hard main layer (20) to suppress corrosion, thereby improving the wear resistance and corrosion resistance of a cemented carbide replaceable knife (10).

摘要： The invention provides a cutting blade reduced in thickness and accordingly produced with less blade materials wherein the flexural rigidity of the whole blade is improved. A base material used in the blade is a steel material, a cemented carbide, or a steel material with a cemented carbide used in an edge part of the blade alone. The blade is a long and thin plate having a nearly rectangular shape and elastically deformable. The blade is approximately 0.5 mm in thickness. In the blade, the use of any costly blade materials is minimized. As a result, the blade is made available at low prices. A flank face of the blade has a clearance angle that equals 0°. In the blade, a predefined area of a rake face including a cutting edge is coated with a chromium nitride hard film. The blade is bent in a direction opposite to a direction of rotation and then fitted in a fitting groove of the tool body. The twist angles on end-surface sides of the blade are positive and negative angles. Therefore, the depth of the blade is circumferentially large enough, and the blade thereby has a higher flexural rigidity than its original flexural rigidity before bending.
摘要翻译：本发明提供了一种减小厚度的切割刀片，并且相应地用较少的刀片材料制造，其中整个刀片的抗弯刚度得到改善。在叶片中使用的基材是单独使用叶片的边缘部分的钢材，超硬合金或具有硬质合金的钢材。该刀片是具有近似矩形形状并且可弹性变形的长而薄的板。刀片厚度约为0.5毫米。在刀片中，任何昂贵的刀片材料的使用被最小化。因此，该刀片可以低价购买。叶片的侧面具有等于0°的后角。在刀片中，包括切削刃的预定面积的前刀面涂覆有氮化铬硬质膜。叶片沿与旋转方向相反的方向弯曲，然后装配到工具主体的装配槽中。叶片端面侧的扭转角是正角和负角。因此，叶片的深度在周向上足够大，并且因此叶片具有比弯曲之前的原始弯曲刚度更高的挠曲刚度。
