摘要： An apparatus and method are provided for performing multiple machining operations on a workpiece such as a crankshaft. Oil holes may be drilled in a crankshaft by a tool shifted along a curved path between successive, acute angle tool plunging locations. The tool's carrier is shifted parallel to the crankshaft axis and the tool carrier is rotated to the desired acute angle about a point on the crankshaft axis for each of successive oil hole drilling locations thereby reducing programming needed to drill the oil holes at the specified angles. Offset tolerance errors are reduced by a large factor as the tool is plunged from an outer initial position toward the crankshaft axis.

At least the first main face includes at least one projection extending to the peripheral edge, the projection formed by: a portion of the first main surface (defining a relief surface), a portion of the side face structure (defining a rake surface), and a portion of the peripheral edge (defining a cutting edge). The insert includes support surfaces defined by a portion of the second main face, and by portions of the side surface structure other than the rake surface.

摘要： A chuck body has an internal cam unit eccentrically mounted within antifriction bearings, and the cam unit includes a workpiece gripper. A radial pin extends through the chuck body into a peripheral slot of the cam unit. When rotating in a first rotary direction, the chuck body and cam unit rotate in unison and a first workpiece diameter may be machined. When the rotation of the chuck body is reversed, inertial forces acting on the cam unit prevent immediate reversal of the cam unit rotation, and the pin moves through the peripheral slot, contacting the opposite end and driving the cam unit in reverse rotation; this relative motion between the chuck body and cam unit causes the workpiece to become offset, displacing the first workpiece axis from the chuck body axis of rotation. Consequently, as the reverse rotation is continued, a second workpiece diameter may be is machined about the chuck axis of rotation; the second diameter will be eccentric to the first diameter.

摘要： A method for manufacturing an assembled camshaft for valve-controlled internal combustion engines, in which at least one cam disc with a base circle region and cam region is machined on the running surface and has a cam-disc recess, includes shrinking the cam disc onto a corresponding shaft designed with a defined dimensional overlap by cooling the shaft and heating the cam disc. Temporally before being shrunk onto the shaft, the at least one cam disc is clamped by a clamping device such that a tension force acts on the recess wall region, which defines the cam-disc recess, the tension force corresponding to a predetermined extent to the state of stresses and/or deformation state of the recess wall region after the operation of shrinking the cam disc onto the corresponding shaft. The running-surface machining of the at least one cam disc takes place when the cam disc is clamped by the clamping device.

摘要： A center hole machining method includes first to fifth steps. The first step includes obtaining outer peripheral shape data of a plurality of portions of the shaft blank in an axial direction. The second step includes obtaining a center axis by comparing measured data of the portions of the shaft blank with design data. The third step includes calculating a minimum distance from the center axis to the outer periphery in each of the portions of the shaft blank. The fourth step includes shifting the center axis in a direction of making the minimum distance greater than the machining dimension and repeatedly executing the third step when the minimum distance is less than or equal to the machining dimension. The fifth step includes boring the center hole in an end surface of the shaft blank at a position arranged on a line extended from the center axis.

摘要： The invention pertains to a process and an apparatus for machining axially symmetrical parts on lathes or rotary broaching machines in which the workpiece is held at each end by an axial clamping pin and a clamping jaw assembly, the clamping pins and clamping jaw assemblies cooperating such that the clamping jaw assemblies may be retracted relative the clamping pins when the ends of the workpiece are being machined and may be extended relative the clamping pins when additional support for the workpiece is desired, as, for example, when the central portion of the workpiece is being machined. The clamping pins and clamping jaw assemblies are movable relative each other and relative the workpiece such that machining of both ends of the workpiece may take place simultaneously or sequentially, followed by machining of the central portion of the workpiece, on a single apparatus and as part of a continuous, uninterrupted machining sequence.

摘要： The subject matter of the present invention is an installation for machining crankshafts, camshafts or like workpieces. Each of the workpiece is mounted in non-rotary condition in a workpiece holder. A plurality of such workpiece holders is guided on a straight path with their workpieces in co-axial relationship to each other and to said path. A plurality of tool units is distributed in spaced relationship along the path. Each unit includes an annular rotary tool having internal cutting edges. This tool surrounds an internal clearance space which is larger than the cross-section of the workpiece holders. Therefore, each tool affords passage of said workpiece holders through the clearance space. Each of the tool units further comprises means for moving the annular rotary tool into a position in which its internal clearance space is in registry with the path of the workholders. Conveyor means are provided for intermittently transporting said workpiece holders with the workpieces on a guideway along the path through the clearance spaces of the tool units and for temporarily stopping each workpiece holder in a position in which its workpiece is surrounded by said annular rotary tool and in a position to be machined by the cutting edges thereof. The conveyor means may comprise drag members which are distributed along the path and are adapted to engage the workpiece holders. These drag members are reciprocated parallel to said path in synchronism with each other and thereby feed each of the workpiece holders step by step along the path consecutively through the annular rotary tools.
