摘要： The radial run-out tool (2), particularly a drill or a cutter, has a basic body (12) extending in an axial direction (4) and comprises at least two chip grooves (14), to which a guide chamfer (22) is connected in the rotational direction (24), with a ridge (15) being formed between them. A radial clearance is connected to the guide chamfer (22). In order to enable simple and economical production of such type of radial run-out tool (2), an unprocessed rod (30) is ground non-concentrically, in a first process step, such that a radius (R) of the unprocessed rod (30) varies, depending on the angle, between a maximum radius (R2) and a minimum radius (R1). In a second process step, the chip grooves (14) are grounded down such that the guide chamfers (22) are formed at the positions with the maximum radius (R2) and the radius (R) is subsequently reduced downstream of the respective guide chamfer (22) in order to form the radial clearance (28).

摘要： An automatic grinding machine for end mills for wood, programmable with optical reading of geometric features and for computerized sharpening, has a compact structure, which includes a computerized control panel actuating various assemblies adapted for automated sharpening. A first optical reading assembly has an arm for automatic movement from an inactive position to a position suited for detecting the geometric features of the end mill. A second assembly for holding the end mill is configured to move on command forward and backward and/or simultaneously rotate the mill about its own axis. A third assembly for supporting a cup grinding wheel is mounted on the vertical frame, which rests on a rotatable circular and horizontal base. The grinding wheel can move above and below, longitudinally along the mill and/or in front of it, on the right and left side to sharpen end mills for wood with a left-handed or right-handed helix.

The model (B.sub.1) has the same outer periphery surface as rotary contour outline of the cutter and is provided with a groove (C) so that there is formed a model line (C.sub.1) corresponding to the required cutting edge of the cutter. The cutting edge flank (24) is grinded easily and accurately in imitation of the model (B.sub.1), by turning the cutter and the model solidly in contacting the model (B.sub.1) with the guide face (61a) at the model line (C.sub.1) and contacting the cutter (A) with the grinding face (31a).

摘要： A machine for machining a spiral cutting edge on an elongate workpiece having a rounded head by moving the workpiece relative to a rotating tool comprises a support unit mounted for vertical translational movement and rotation about a vertical axis. The support unit carries a headstock which can be positioned to make the axis of its workpiece-carrying spindle intersect the vertical axis, and a device for helicoidally driving the headstock spindle. The support unit rests on an inclined ramp surrounding the vertical axis and along which the unit can roll to helicoidally move the headstock for spirally machining a cutting edge into the rounded end of the workpiece. Thereafter a spiral cutting edge is machined into the cylindrical shaft of the workpiece, smoothly continuing the rounded, spiral edge.

摘要： The method of grinding or sharpening axial-thrust cutting tools consists in bringing the tool to a first position for grinding the rake plane, the tool axis lying in a vertical plane inclined to the horizontal median plane of the grinding wheel according to the rake angle, with the tool centre coincident with the point of intersection of the tool axis with the pivot axis of the jig supporting the tool-holder, the tool being subsequently brought to another position for grinding the cutting face passing through the centre of said tool by pivoting said jig about said jig pivoting axis, in combination with an angular setting, obtained by pivoting said tool holder about its pivot axis passing through said point of intersection, and eventually bringing said tool to a third position for grinding the small face bounding the cutting lip in the central portion of the tool tip, by pivoting said jig in a direction opposite to the direction of the movement having led to said second position.

摘要： A complete installation is provided for grinding cutters, especially and typically, end mills, by machine controlled operations. The installation has three separate stations which, when all are used, provide maximum flexibility in the shape imparted to the end mill, accuracy of grind, and the ability to repeat or duplicate a particular grind on a series of duplicate cutters. The only manual operations are loading and unloading the end mills at each of the stations; and consequently the grinding of the mill is accomplished rapidly and at low cost.

摘要： A method and apparatus for mechanically grinding the end cutting teeth in a tool (such as a ball nose end mill) having spiral flutes and end cutting teeth that join with axial fluting. Rotary movement of an end cutting tool about a vertical axis is mechanically transmitted into corresponding rotary movement of the tool about its own axis to uniformly and precisely generate a helical grind from a starting point on the nose of the tool to a blend with a helical axial flute. When doing work on a ball nose end mill, the present invention produces a gash with a desired rake, for example, a positive rake, and by tilting the grinding wheel the same machine is then used for grinding both the primary and secondary relief of the end cutting teeth.
