Abstract: In the radius end mill, main gash faces has an angle of inclination with respect to an axis that is smaller than a twist angle of chip discharge flutes. The main gash faces are formed on inner circumferential sides of distal end portions of wall surfaces that face in a tool rotation direction of helically twisted chip discharge flutes, which is formed on an outer circumference of a distal end portion of a tool body that is rotated around the axis. End cutting edges are formed on a distal end of the main gash faces. Sub gash faces has an angle of inclination with respect to the axis that is greater than that of the main gash faces. The sub gash faces are formed on an outer circumferential side of the main gash faces such that they extend away via step portions from the main gash faces. In addition, corner cutting edges that have a protruding arc-shaped contour are formed to be continuous with an outer circumferential side of the end cutting edges extending from a distal end as far as an outer circumference of the sub gash faces.

Abstract: In this insert, in addition to the insert being formed so that the cutting edge is twisted at a helix angle within the range of 5° to 25° about the axis when the insert is attached to the insert mounting seat, the thickness of the insert body at the flank located on a straight line, which passes through the center of the rough hemisphere formed by the rotational locus of the cutting edge and forms an angle of inclination of 90° relative to the axis, is set to be within the range of 0.5D to 0.9D relative to the thickness D of the rough plate that composes the insert body. As a result, since a comparatively gentle but adequately large helix angle is imparted to the cutting edge, cutting resistance decreases. In addition, since the thickness of the insert body at the flank on the rear end side of the insert body is not excessively thin, the rigidity of the insert body is adequately secured.

Abstract translation: 在该插入件中，除了插入件之外，当插入件附接到插入物安装座时，切削刃以围绕轴线的5°至25°的范围内的螺旋角度被扭转，插入件的厚度 在通过切削刃的旋转轨迹形成的粗糙半球的中心的直线上的侧面上形成相对于轴线形成90°的倾斜角度的主体被设定在 相对于构成插入体的粗板的厚度D为0.5D〜0.9D。 结果，由于赋予切削刃相当温和但足够大的螺旋角，所以切削阻力降低。 此外，由于插入体在插入体的后端侧的侧面的厚度不会过薄，因此能够充分确保插入体的刚性。

Abstract: An end mill chucking structure for chucking an end mill having a relatively small diameter and used, for example, for deep milling of a die. The end mill chucking structure includes an end mill holder and an end mill. A holder body has a taper hole formed therein. The end mill includes an end mill body and a cutting tip provided at an end portion of the end mill body. A portion of the end mill body located opposite the cutting tip serves as a tapered shank portion. The shank portion and the rest of the end mill body are bounded by a shoulder extending outward from the surface of the shank portion. The shank portion is press-fitted or shrink-fitted into the taper hole such that the end face of the holder body abuts the shoulder of the end mill body, through application to the holder body of heat at a temperature lower than a conventional shrink-fitting temperature.

Abstract: To increase the sturdiness and precision of a double-edged milling cutter having a single cutting tip, the cutting tip is inserted in a recess of a milling cutter body, with the recess being constituted by two spaced-apart opposite sidewalls. One sidewall is designed as a rigid sidewall. By way of a cavity extending transversely of the longitudinal axis of the milling cutter body, the thickness of the other sidewall is locally reduced across the entire width thereof, so that it is "elastic". The cutting tip is fixed between the two sidewalls by means of a mounting screw.

Abstract: A cutting plate for a ball-head finish miller has a support body of hard metal centered on an axis and having a pair of oppositely directed and symmetrically oriented faces each formed with a respective substantially circularly segmental recess of a predetermined depth. A pair of substantially identical and substantially circularly segmental cutting inserts are each secured to a respective one of the faces in the respective recess and each have a respective cutting layer forming a cutting edge. The inserts and their edges are symmetrical with respect to the axis and are each of a thickness substantially less than the depth of the respective recess so that each forms a chip cavity on the respective face.

Abstract: A cutting tool particularly adapted for machining brittle plastics in which the cutting head has its cutting edges in the first and fourth quadrants of the x-y axes and contained in a common plane on opposite sides of the axis of tool rotation. The cutting edges are on two planar inserts, which can be either integral or separate elements, which meet at the common plane and each of which is relieved or cut away in the opposite quadrant from its own cutting edge to expose the cutting edges of the other. The walls defining the reliefs have 2 or more non-aligned sections forming different angles with the axis of rotation with the steepest angle beginning at the axis and preferably inwardly of the tip of the tool and, overall, exposing not less than a full quadrant of the cutting edge of the other insert while providing cavities and contours which control the movement of the chips and the flow of coolant fluids. The shank which holds the cutting head includes a fork whose tines embrace the planar inserts and include contouring compatible with the geometry of the reliefs to allow for the flows of chips and coolant, the paths for which are formed in the shank and inserts in complementary fashion.
