| 141 | Beveling attachment for end mill | JP19008989 | 1989-07-20 | JPH0355106A | 1991-03-08 | KAJIYAMA TOUICHI |
| PURPOSE: To omit the beveling work of the corner of the work upper face and groove inner face at a post-stage and to improve the working efficiency by performing grooving by an end mill to which the collar fitted with beveling edges in the same number as the edges of the end mill is fitted freely detachably. CONSTITUTION: A beveling attachment is formed by fixing to a collar 2 beveling edges 6 in the same number as that of the edge 19 of an end mill 1 and making the angle of 45° to the end mill 1. The collar 2 is fitted to the end mill 1 from the lower part thereof, the lower end of the beveling edges 6 of the collar 2 lower part is inserted into grooves 1b located between the edges of the end mill 1, the collar 2 is lifted to the necessary position while rotating it by setting to the twist of the edge 1b of the end mill and fixed to the end mill 1 by the fixing means composed of a fastening screw 4, etc. When grooving, etc., are executed accordingly, the beveling edges 6 formed in their insertion state from the collar 2 to the grooves 1b between edges of the end mill 1 bevels the corner of the groove inner face 7b and upper face 7a of a work 7 under working and the need for the beveling work at the post stage is eliminated.

| 142 | Throwaway end mill | JP11145389 | 1989-04-28 | JPH02292108A | 1990-12-03 | MATSUMOTO KEIICHI |
| PURPOSE: To allow rear face machining for a (T) groove, even if small in height, in a throwaway end mill which is composed of a throwaway chip and a shank for fixing the chip by forming the throwaway chip into isosceles right triangle to install a cutting edge on the slope of the isosceles right triangle. CONSTITUTION: A throwaway end mill is made up with an isosceles-right-triangle throwaway chip 1, a shank 2 and a set screw 3, and the throwaway chip 1 has a cutting edge 1a installed on the slope portion of a isosceles right triangle. In case that the throwaway end mill is used to perform rear chamfering for a (T) groove 5a, the throwaway end mill held by a collet holder 6 can have a small edge height h 1 because the throwaway chip is formed into isosceles right triangle. It is thus possible to perform chamfering even if the groove 5a has a small bottom height (H). COPYRIGHT: (C)1990,JPO&Japio | ||||||

| The invention relates to a double-sided cutting insert (10) for milling, comprising an upper face (11), a lower face (12), and a circumferential lateral surface (13). A first (14) or a second cutting edge (15) is formed at the transition from the upper (11) or lower face (12) to the lateral surface (13). The cutting insert has a fourfold rotational symmetry with respect to an axis of symmetry (Z), and a reference plane (XY) running perpendicular to the axis of symmetry. The first cutting edge (14) and the second cutting edge (15) each have four cutting edge segments (20, 20', 20", 20"'), wherein the cutting edge segments each consist of a main cutting edge (21, 21', 21", 21"') and a face cutting edge (22, 22', 22", 22"') which are connected to each other via an associated rounded cutting corner (23, 23', 23", 23"'). The first and second cutting edges (14, 15) each have the greatest distance from the reference plane (XY) in the region of the cutting corners (23, 23', 23", 23"'). In the circumferential lateral surface, main free surfaces (24, 24', 24", 24"') or face free surfaces (25, 25', 25", 25"') are formed directly contacting an assigned main cutting edge or face cutting edge, wherein the exterior angles (ρ) formed between the main free surfaces and the reference plane are greater than the exterior angles (σ) formed between the face free surfaces and the reference plane. | ||||||

| 150 | DEVICE AND METHOD FOR FORMING A HOLE THROUGH A GLASS PLATE, AND A DRILLING TOOL USED THEREIN | EP15186713.2 | 2015-09-24 | EP3006176A1 | 2016-04-13 | GENNARI, Gianluca; LONGATO, Roberto; BELLI, Marco |
A through hole (H) is obtained in a glass plate (L) by engaging a drilling tool (D) on the glass plate (L) only from one side of the plate. The drilling tool (D) is rotated around its axis (A) while at the same time it is imparted with an axial movement of advancement through the glass plate (L) and with a planetary movement of rotation around a main axis (A1) which is parallel and spaced apart with respect to the axis (A) of the tool. As a result, the drilling tool (D) advances through the glass plate (L) by performing a helical movement. Once a hole (H1) is formed through the glass plate (L), the diameter of the hole (H1) is enlarged until reaching the desired diameter by a milling operation of the wall of the hole (H1). This milling operation can be carried out by using the same drilling tool (D). To this end, the tool has a front abrasive surface (40) of a substantially spherical shape, for performing the first drilling stage, and an axial stem (3) having an abrasive surface with a grain size smaller with respect to that of said front surface (40), which is used for performing the second milling stage.
