摘要： A centerless roll grinding machine includes a lateral support of a V-channel support that is received by a vertical support of a frame and extending horizontally in the first direction to contact a second side of one neck of a work roll. A lower support received by and extending generally upwardly from the frame displaced in the first lateral direction from a geometric center of the neck of the work roll cooperates with the lateral support to provide the V-channel support to hold the work roll for rotation about a longitudinal axis. A lateral support device includes radially spaced bearing pads on the neck in opposition to a grinding wheel. Each pair of bearing pads is pivotally attached to a respective first tier averaging link that is pivotally coupled to a horizontal ram to reduce displacements of the work roll caused by errors in the neck.

摘要： A method and device for simultaneous centerless cylindrical grinding of multiple workpieces (11, 12, 13, 14), at least sections of which are rotationally symmetrical, the workpieces are arranged on a support apparatus (200) one behind the other between at least one grinding wheel (110) and at least one regulating wheel (120), and wherein the axis of rotation of the regulating wheel is inclined with respect to a horizontal plane extending parallel to the workpiece axes of rotation and the grinding wheel axis of rotation by an inclination angle (α). During grinding the workpieces are arranged with a height offset relative to each other corresponding to at least a quarter of the inclination angle (α) of the axis of rotation of the regulating wheel with respect to the parallel plane to render the respective bearing angles (γ) of the workpieces on the inclined regulating wheel consistent.

摘要： Cylindrical rolling bodies, methods of producing the rolling bodies, and anti-friction bearings including the rolling bodies are disclosed. A method of producing the rolling bodies may include a) providing a spherical blank having a diameter (D) and a radius; and b) grinding the spherical blank into a cylindrical shape having a predefined diameter (d) and a length (L) that corresponds to the diameter (D) to form a cylindrical rolling body. After grinding, the cylindrical rolling body may have crowned end surfaces each having a radius corresponding to the radius of the spherical blank. Centerless cylindrical plunge grinding or centerless cylindrical throughfeed grinding may be used as the grinding method.

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： The invention relates to an apparatus for fine-working or microfinishing of workpiece surfaces, particularly rotationally-symmetrically moved workpieces with oscillating or rotating tools such as honing stones or fine polishing stones, which are in-fed against the workpiece. Dependent on a measured parameter proportional to the machining force, the tool infeed is controlled such that a continuous workpiece material remove with constant removal speed is achieved. The reaction force is measured at any point in the flux of force to determine the machining force.

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.

摘要： Centerless honing machines are described for honing external cylindrical surfaces on a series of workpieces. Each machine comprises a pair of spaced adjacent rotary rollers for supporting and rotating workpieces while also causing them to travel axially along the rollers, at least one honing stone for engaging and honing the workpieces, a fluid pressure operated device for pressing the honing stone against the workpieces, a gaging device for gaging the size of the workpieces and for producing gaging signals, a pressure regulator for supplying fluid pressure to the fluid pressure operated device, and control means operable in response to the gaging signals for adjusting the pressure regulator to increase or decrease the fluid pressure and thereby to increase or decrease the amount of stock removed from the workpieces by the honing stone to achieve closer agreement between the finished size of the workpieces and the desired size.
