摘要： A rack bar includes a shaft member having a toothed section. The toothed section has a plurality of rack teeth, and extends over a portion of an entire length of the shaft member along a longitudinal direction of the shaft member. The shaft member has a grinding-finished outer peripheral surface extending over the entire length of the shaft member including the toothed section. A method for manufacturing the rack bar includes forming the toothed section by plastic working and grinding the outer peripheral surface to improve shape accuracy.

摘要： A motorized blade rest apparatus for a grinding system includes a carriage, a ram assembly, a work rest assembly, a motor, and a computer processor. The carriage moves a regulating wheel along a first axis towards and away from a work wheel. The ram assembly, which moves along a second axis parallel to the first axis, supports the carriage and the work rest assembly. The work rest assembly includes first and second slide portions and a work rest blade. The first slide portion is mounted on the ram assembly. The second slide portion, which is movable relative to the first slide portion, moves along a third axis perpendicular to the first axis. The work rest blade is mounted on the second slide portion. The motor is coupled to the second slide portion, and the computer processor controls the motor to move the second slide portion along the third axis.

摘要： A grinding device for grinding a cylinder that has a rotating shaft includes an immovable component, a movable component, and a grinding component. The immovable component has a positioning unit. The cylinder has the rotating shaft positioned by the positioning unit. The movable component has a carrying portion and is such installed on the immovable component that the movable component can move axially along the rotating shaft. The carrying portion positionally corresponds to the cylinder. The grinding component is located on the carrying portion and positionally corresponds to a surface of the rotating shaft. The grinding device thereby is able to grind the rotating shaft of the cylinder evenly with reduced labor costs.

摘要： On a workpiece there are first longitudinal portions which are rotationally symmetrical with respect to the continuous longitudinal axis and are intended to be ground by way of centerless grinding. The workpiece also has a second longitudinal portion, which is not rotationally symmetrical with respect to the longitudinal axis and would lead to imbalance in the event of rotation. Therefore, a balancing weight having a radially extending recess is placed on the second longitudinal portion. The balancing weight contributes largely to uniform distribution of the rotating masses, thus reduces the imbalance to a very low residual imbalance and allows reliable and precise centerless grinding.

摘要： Disclosed is a grinding tool (1) for highly accurate centre-less grinding in continuous process for shaft-like workpieces (16), comprising at least one conical (3) and one cylindrical grinding region (4). With its first grinding cover (13), the conical grinding region (3) is primarily intended for grinding larger cutting volumes, whereas the cylindrical grinding region (4), with its second grinding cover (14) is primarily intended for achieving the highest surface quality, without, in the case of the latter, having to remove large cutting volumes. The grinding covers (13, 14) differ at least in respect of the grinding agent used, CBN preferably being used in the conical region and diamond being used in the cylindrical region. Further disclosed is a method, which works with the grinding tool (1) as per the invention and which grinds the shaft-like workpieces (16). Oversize and surface quality are at least temporarily simultaneously ground.

摘要： A bearing having bearing elements made of Type 60 Nitinol made by an investment casting process for producing near net shape parts of Nitinol includes making a ceramic mold having a series of spherical cavities, pouring molten Nitinol into the mold cavities, cooling the mold and the Nitinol in the cavities to produce solidified Nitinol balls, and breaking the mold away from the Nitinol balls. Nitinol rods for roller bearings can be made by conventional casting directly from the crucible in a draw-down oven. The bars are hot machined or hot rotary swaged and then centerless ground and laser cut to length, or are first cut to length and then centerless ground individually for crowned roller elements. The balls are broken or cut from the risers, leaving the gates attached, and are consolidated by healing under pressure in a hot isostatic press, then ground to the desired size. The balls or rollers are polished, then treated to create an integral ceramic finish. They are then repolished to produce an extremely smooth finish. The balls can also be cut from a sheet or plate of the ball material as cubes or cylinders and processed in an abrasive tumbler to round off the corners and edges, and the rounded cubes or cylinders can hen be ground to spherical form in conventional ball grinder.

摘要： In a method for minimizing the roundness error in an workpiece having a generally circular periphery during centerless grinding of the workpiece, the workpiece is rotatably supported on the upper surface of a first workpiece support between the grinding wheel and the second workpiece support, with the first support rotatably supporting the workpiece in contact with said grinding wheel and said second support. The .alpha.-setup angle and .beta.-setup angle cooperate with a cutting ratio to define the transfer function of a lobing loop system in the complex u-plane, and the lobing stability of the lobing loop system is thereby determined. The workpiece is rotated against the rotating grinding surface of the grinding wheel, and the magnitude and frequency of grinding disturbances causing the roundness error in the workpiece are detected. The .beta.-setup angle is modified to minimize the workpiece roundness error by minimizing the response of the lobing loop system corresponding to the detected grinding disturbances, and the ratio of the rotational speed of the grinding wheel to the rotational speed of the workpiece is adjusted to further minimize the workpiece roundness error by generating only precessing waves of minimum magnitude in the workpiece.

摘要： A centerless valve regrinder for resurfacing a worn valve having a face, a tulip connected to the face, a valve stem connected to the tulip, the stem having an axis, a first notch worn into the stem at a location spaced from the tulip, and a second notch worn into the stem at a second location spaced from a distal end of the stem. The regrinder is comprised of a power-driven means for resurfacing said valve face, and a chuck for supporting the valve stem in such an orientation as to cause contact between the valve face and the means for resurfacing at the angle of bevel of the valve face. The chuck is also comprised of a wheel for rotating the stem about its axis and simultaneously drawing the valve face into contact with the means for resurfacing. The chuck is further comprised of two fixed supports that are in parallel orientation and of sufficient length to cradle and support the stem from respective points adjacent the tulip to respective points past the first notch, and preferably past the second notch. Preferably, there is no stop member to contact the distal end of the stem to limit the regrinding.
