    摘要: A magnetic transducing core having a transducing face defined by planes whose surfaces comprise substantially parts of ferrite grains, and a method for producing this core. The method involves proper selection of the grit size and binder of a diamond grinding wheel, machining its sides to precise parallelism with each other, mounting it on a highly accurate air bearing, rotating it at high speed, and feeding a work piece ferrite bar from which the core is cut into the rotating wheel. These techniques prevent axial run-out between the edge of the cutting portion of the wheel and the work piece greater than 2.5 microns. A preferred embodiment includes a high pressure jet of coolant impinging on the wheel just ahead of the cutting interface.

    摘要: A method of calibrating an analog machining sensor of the varying resistance type which has been deposited on a surface involves depositing adjacent it with great positional accuracy relative to a feature on the surface, discrete machining sensors. As machining takes place, the discrete sensor's continuities are successively broken as the analog sensor's height is reduced and its resistance increased. Measuring the resistance of the analog sensor at the time each discrete sensor breaks yields values from which the position of the analog sensor's machined edge can be very accurately related to the position of the feature on the surface.

    摘要: A workpiece carrier has a support bar centrally supported at one end of a stem portion. The stem is carried at its opposite end on a base. Columns are interposed between the ends of the support bar and the base. Heat is applied to the columns, preferably by resistive heating elements, to heat them and cause their thermal expansion, causing the support bar ends to be bent away from the base. A relatively flexible workpiece which has been bonded to the support arms on a surface facing away from the base will undergo the same bend.

    摘要: Apparatus for precisely machining the surface of a workpiece comprises a rotating plate with a flat, horizontal abrasive-laden surface against which the workpiece surface is forced by gravity. The workpiece is carried on the free end of an arm pivotably supported remote from the end of the arm carrying the workpiece. Loading of the workpiece work surface can be varied by shifting weights along the length of the arm or transverse to the length of the arm. The workpiece itself can comprise a bar on which several magnetic transducing heads have been deposited. Machining the workpiece surface to a preferred position accurately defines a dimension of choice, such as the throat height of these transducers.

    摘要: A magnetic head is manufactured by depositing a layer of spacer material onto the facing surfaces of the magnetic cores; the thickness of each layer being approximately one-half the length of the intended gap and the thicknesses of both layers together being approximately equal to the thickness (length) of the gap. A layer of bonding glass is deposited onto the surfaces of the spacer layers and the cores are pressed together at an elevated temperature to fuse the glass layers and extrude most of the glass.

    摘要: A workpiece carrier includes a flat support surface to which a workpiece is attached by bonding. The carrier includes means for bending the carrier support surface so that it becomes concave. When dealing with a relatively flexible workpiece, one can cause the workpiece's surface to be machined to attain a convex shape by bending the support surface of the carrier concavely, and then bonding the workpiece attachment surface to the carrier while the carrier support surface is concavely bent. Allowing the carrier's support surface to assume a less concave shape then imparts a convex shape to the surface of the workpiece to be machined.

    摘要: An article and a method for manufacturing the same, for use as a jaw face of a vise and which applies pressure evenly along any approximately flat surface clamped therein. The face comprises a plurality of cantilevered beams integral with the body of the jaw. The beams are spaced apart from each other and in the preferred embodiment have along a corresponding exterior surface of each, a pair of projections the tips of which are tangent to a geometrically flat plane. When the jaw is used, the projections bear against a flat surface of the workpiece to be clamped and the individual beams deflect slightly to correct for deviations from flatness in the flat surface, thereby assuring that the clamping force is distributed relatively evenly along the surface.

    摘要: An article and a method for manufacturing the same, for use as a jaw face of a vise and which applies pressure evenly along any approximately flat surface clamped therein. The face comprises a plurality of cantilevered beams integral with the body of the jaw. The beams are spaced apart from each other and in the preferred embodiment have along a corresponding exterior surface of each, a pair of projections the tips of which are tangent to a geometrically flat plane. When the jaw is used, the projections bear against a flat surface of the workpiece to be clamped and the individual beams deflect slightly to correct for deviations from flatness in the flat surface, thereby assuring that the clamping force is distributed relatively evenly along the surface. A preferred method for manufacturing this article comprises the making of a plurality of cuts perpendicular to the jaw face of a block, which carries the projections. A second slot is cut to completely intersect each first slot, cutting the entire breadth of a first side intersecting the jaw face, and extending partially toward a second side opposing the first and also intersecting the jaw face. If more deflection is required, a third slot similar to the second but cutting the entire breadth of the second side and extending toward the first side in spaced relation to the second slot may be cut.
