| 61 | Pin mirror cutter, and throw-away tip mounted on the pin mirror cutter | US10595650 | 2004-10-26 | US07938599B2 | 2011-05-10 | Syoji Takiguchi; Motoshi Shirai; Toshiyoshi Watanabe |
| A throw-away tip is mounted on a first tip mounting seat of a pin mirror cutter. In the throw-away tip, cutting edges are formed at intersecting ridgeline parts between a pair of oppositely disposed long side faces of a substantially trapezoidal flat-plate-shaped tip body, and upper and lower faces of the tip body. A thickness direction of the tip body is approximately aligned with a radial direction of the cutter body to provide curved edges formed in acute corner parts of the tip body for cutting. The tip is mounted on a second tip mounting seat of the pin mirror cutter such that the thickness direction of the tip body is approximately aligned with an axial direction of the cutter body to provide curved edges formed in obtuse corner parts of the tip body for cutting. | ||||||

| Disclosed is a method for machining the bearing seats (HL, PL) of shafts (1), especially crankshafts. According to said method, the bearing seats (HL, PL) are subjected to the following machining operations after initially shaping a shaft (1) in a forging or casting process: the bearing seats (HL, PL) are preformed by cutting the same using a specific cutting edge; they are hardened; they are passed through dressing rollers; they are subjected to a preliminary rotary milling process; and they are subjected to a final rotary milling process. The preliminary and the final rotary milling process are carried out during substantially an entire rotation of the shaft (1) without longitudinally or tangentially advancing the milling cutter (12). | ||||||

| The invention relates to a method for machining crankshafts during which the machining of the bearing width and of the oil collar should be carried out simultaneously. To this end, a disk-shaped outer milling cutter having a number of cutting tools (10, 14) is used of which a portion serves to machine a bearing base of the crankshaft and the other portion serves to machine an oil collar adjacent to the bearing base. According to the invention, a set angle (κ) for the cutting tools for machining the oil collar is selected according to the actual dimension, during which the effective depth of cut hmax for each cutting insert is limited to a predeterminable maximum value. The invention also relates to a device for carrying out this method. | ||||||

| A crankshaft (6) is rotated about its axis (7), and all of its crankpins (28, 29, 30), which each respectively have an eccentricity (e) relative to the axis (7), are simultaneously rotary milled by respective allocated rotary milling cutters (34, 35, 36) of a milling cutter set (12). The individual milling cutters (34, 35, 36) each respectively have an eccentricity (e) corresponding to the eccentricity of the respective crankpin that is allocated to be machined by the respective milling cutter. Furthermore, the milling cutter set (12) is rotated at the same rotational speed, i.e. with a rotational speed ratio of 1:1, relative to the rotating crankshaft, while simultaneously the milling cutter set is moved in the X-direction toward the crank-shaft axis to achieve a feed advance. A rotary milling machine for carrying out the method includes a milling cutter set of which the milling cutters respectively have the same eccentricity as the respective allocated crankpins of the crankshaft to be milled, and includes a drive apparatus for achieving the 1:1 rotation of the milling cutter set relative to the crankshaft as well as the feed advance motion of the milling cutter set. In this manner, the milling cutters automatically follow the eccentricity of the crankpins, without requiring a complicated individual guidance. | ||||||

| A method of machining with a crankshaft miller to machine a workpiece into a crankshaft with pin and journal portions is disclosed in which a crankshaft workpiece is held in a chuck and is machined for at least a part of pin and journal portions of it with a cutting edge of a cutter body attached to a rotating cutter drum. In this method, such a cutter body is prepared having a diameter of its inner peripheral surface that is slightly larger than the diameter of a pin or journal portion of the workpiece to be machined. The cutter body so prepared is attached to the cutter drum via an adapter having an opening which is larger in diameter than both a diameter of the chuck and a maximum swing of the workpiece. Then, the cutter drum is positioned at a standby site in an area where the chuck is located and the workpiece is secured and held in the chuck. Then, after the workpiece is indexed or determined with respect to its phase position, the cutter drum is moved in a longitudinal direction of the workpiece to position the cutter body at a given machining site and is rotated to machine that portion with the cutting edge of the cutter body. These steps are repeated for all machinable pin and journal portions at altered machining sites. A cutter apparatus for performing the method is also disclosed. | ||||||

| The present invention relates to a method and an apparatus for the finish-machining of the bearing diameters, particularly the main bearing diameters and of the adjoining cheek side surfaces on crankshafts and similar workpieces in a single chucking. In order that this machining can be carried out rapidly and nevertheless with a high quality of production, the following method steps are carried out, one after the other: milling of the cheek side surfaces to nominal size up to the bearing diameter; turning of the bearing diameter down to a small oversize; turning-broaching of the bearing diameters to nominal size in order to obtain a good quality surface, and possibly turning/turning-broaching of recesses, clearance cuts and undercuts in the region of the bearings. | ||||||
