摘要： An annular array of workpiece retaining frame assemblies are mounted on a rotary work carrier for advancing a multiplicity of workpieces, such as coiled compression springs, between one or more pairs of abrasive discs. The work carrier comprises a series of equal segments each of which supports a pair of arcuate workpiece retaining frame assemblies. Each assembly comprises a frame which lockingly embraces a number of work retaining elements or bushings in rows concentric to the carrier axis thereby to carry a maximum number of workpieces, of given diameter within a given annular area. Locking is accomplished by a series of spaced clamping screws in an arcuate peripheral frame wall which serve to force the total complement of bushings into tangential interlocking contact with each other and toward a rigid arcuate inner frame wall provided with locating depressions. The peripheral frame wall and the walls connecting the arcuate walls are made capable of flexure and the clamping screw force applied is such that the peripheral outer wall bows and the radial side walls of each frame are drawn toward each other when the clamping screws are tightened, and contribute to the clamping action or locking up of the workpiece retaining elements.

摘要： A double disc abrading machine, such as a double disc grinder, which is particularly adapted for grinding opposite surfaces of thin workpieces (W), includes the injection of a metered amount of air into the coolant supplied through the spindles (13L and 13R) to eliminate a partial vacuum formed between the abrasive discs (14L and 14R). It is believed that hydrodynamic forces create a partial vacuum between the closely spaced abrasive discs (14L and 14R) which are rotated in the same or opposite directions. There may also be cohesive and/or adhesive forces acting to draw the abrasive discs (14L and 14R) too close together. It is believed that this combination of forces and the ambient air pressure exerted on the outside of the abrasive discs (14L and 14R) causes the workpieces (W) to be ground undersize. The metered air is injected into the coolant during the grinding process to eliminate the vacuum effect. In some instances it is desirable to add supplementary un-metered air at the completion of the grinding process so that the discs may be retracted in unison at a rapid rate.

摘要： This disclosure relates to automatic machines for grinding workpieces having axially spaced portions of different diameters, and particularly relates to a gauge mechanism which is used to determine the unground diameter of each workpiece portion to assure that the workpiece is within certain tolerances so that the grinding wheel may be advanced rapidly to a point just out of contact with the workpiece before reducing the rate of approach for the grinding feed. The gauge mechanism includes a workpieceengaging element or caliper of a chordal type having upper and lower shoe portions and a centrally located gauging probe member which is movable to cover a wide range of workpiece diameters. The work-engaging element is suspended by pivoted links of different lengths to permit the centerline of the probe to pass through or near the center of the workpiece, regardless of the workpiece diameter, so that each shoe portion will contact the work simultaneously.

摘要： This disclosure relates to a work-driving apparatus, particularly for a cam contour grinder, for applying a driving torque at two angularly spaced points on a workpiece so that the entire force transmitted by the work-driving apparatus acts to turn the workpiece and there is no force to cause radial displacement of the workpiece. The work-driving apparatus is particularly adapted for use in conjunction with a workpiece having an end portion of a reduced diameter with a keyway formed therein. The work-driving apparatus includes a driving block which carries a locating pin which is proportioned for a close fit in the keyway to maintain the workpiece in a predetermined oriented position during the grinding thereof. The driving block is mounted for floating movement so as to compensate for variations in workpieces and is pivotable about the locating pin to engage a separately mounted jaw carried thereby with the workpiece at a point circumferentially remote from the locating pin.

摘要： This disclosure relates to a control mechanism for automatically actuating a feed mechanism for a machine tool slide to shift the slide from a known prior position to a selected new position. The control mechanism primarily consists of an electrical circuit of the logic type which differs from prior utilized circuits in the following manner: 1. There is no control element such as a switch or similar device for providing a signal to indicate when the slide is in or passing through the selected position. 2. The ''''On The Target'''' signal is obtained when the output from a position indicating encoder coincides with the input from a dial or punch card. 3. The ''''Forward'''' signal is obtained when the output from the position encoder is greater than the input from a dial or a punched card. 4. The ''''Reverse'''' signal is obtained when the output from the position encoder is less than the input from a dial or a punched card. A signal is available not only to stop a driving member, but also to signal a circuit for reversing the driving member and determining the speed at which the driving member drives the slide. The final movement of the slide towards the selected position is always in the same direction, that is, forward and at a minimum of speed referred to hereinafter as a ''''Creep'''' speed. When the slide reaches the selected position at this speed and the position signal stops the driving member, there is not sufficient inertia to carry the slide beyond the positioning movement. When the set new position of the slide is an initial position, further advance of the slide for machining operation is effected by the usual feed mechanism.
