摘要： PURPOSE:To perform boring processing of highly tough and soft materials such as aluminum with high accuracy by setting the torsion angle, that is the axial direction face angle of tip cutting blade to, 30 deg.-40 deg.. CONSTITUTION:Tip cutting blades 1 are provided at every 120 deg. of the central angle and the web thickness W in relation to the outer diameter D is set within the range of 0.25D-0.5D. Groove width rate (alpha1:alpha2) is set within the range of 1.3:1.7-1.7:1 and the torsion angle gamma is set within 30 deg.-40 deg.. And the radial face angle at a random point on the tip cutting blades 1 is varied along the tip cutting blades 1. Thus highly tough and soft materials such as aluminum member can be bored with high accuracy.

摘要： PURPOSE:To prevent the occurrence of shipping at the initial cutting of a ceramic insert chip by forming a flank land for chamfering between a flank and a negative land, and selecting pertinently the angle and the width of the flank land. CONSTITUTION:A chamfering process is conducted between a flank 1 and a negative land 2, a flank land 3 is formed and cutter angles theta1 and theta2 at points P1 and P2 on the cross line of the negative land 2 and the flank 1 are made larger than conventional cutter angles. An angle formed by a plane S2 passing the point P2 and perpendicular to a bottom plate 4 and the flank land 3, or a flank land angle alpha2 can be treated as a clearance angle for a cutter, the flank angle of a cutter proper is set to a range of -10 deg.-+30 deg., thereby positioning the flank land 3 in parallel with a cutting face, and breadth 'T' is made about 0.1-0.6mm on the basis of about 1mm for flank abrasion length at the complete service life of a ceramic chip. Therefore, an initial cutting load is dispersed and chipping is reduced.

摘要： PURPOSE:To allow internal tensile stress to remain in the specific section of a circular saw so that clattering and oscillating of the circular saw during cutting are effectively prevented by attaching rings to the sections of the prescribed radial circle on both side faces of the circular saw and subjecting the entire part to quick heating and quick cooling. CONSTITUTION:Respectively circular residual tensile stress parts 1b are held on both side faces 1a of the circular saw 1. The radius of the circular saw is designated as R and the radius of the residual tensile stress 1b as (r), then (r) is so set as to satisfy 0.65R

摘要： PURPOSE:To improve cutting efficiency and cutting accuracy, by pressurizing a circular part in a radius of 40-73% the external radius in both side surfaces and generating internal stress of compression to be left in the pressurized part so as to prevent a chattering vibration during cutting. CONSTITUTION:A circular saw 1 has in its both side surfaces 1a two circular pressurized parts 1b, 1c of different diametric size. A radius of said two circular pressurized parts 1b, 1c, if assumed R for radius of the circular saw 1, is in a value of 0.73R-0.40R. In the case of the drawing, as an example, the radius is respectively in a value of 0.70XR, 0.60XR. The above pressurized parts 1b, 1c are easily constituted by roll pressurization as shown in the bottom drawing. That is, the circular saw 1, arranging in its both side surfaces 1a, 1a a pair of pressurizing rolls 2a, 2b to be mutually opposed and moving each pressurizing roll 2a, 2b in the direction of an arrow head in the drawing to pressurize the circular saw 1 while gradually rotating each pressurizing roll 2a, 2b, forms the circular pressurized parts. The circular saw enables internal stress of compression to be left in the pressurized part by applying said pressurizing process. This residual stress is generated to, for instance, 20-30kg/mm .
