摘要： A circular grinding machine wherein the upper side of the base for the reciprocable tool supporting unit slopes upwardly from the front side toward the rear side of the base. The headstock and a reciprocable tailstock are mounted at the front side of the base so as to support workpieces at a level above a collecting vessel for spent liquid coolant which is sprayed or otherwise guided against the workpiece during removal of material. The ways for the carriage of the tool supporting unit and the ways for the tailstock are covered by shrouds so that their temperature cannot be influenced by the coolant, and the workpiece which is held between the centers of the headstock and tailstock is located in front of the base so that the major percentage of liquid coolant which descends from the material removing station into the collecting vessel bypasses the base. In this manner, the temperature of the base and/or of the ways on the base is not influenced by the coolant and any coolant which descends onto its upper side flows immediately toward and into the collecting vessel.

摘要： A surface grinding machine wherein the turret for two grinding tools is indexible with reference to a support by disengaging the surfaces of its two coaxial sections from opposite sides of an annular component of the support. This is effected by cylinder and piston units which move one of the sections axially of any away from the other section before moving the other section away from the annular component. The one section carries one portion of a first bearing which engages the other portion of such bearing on the support when the one section is disengaged from the annular component. The other section carries one portion of a second bearing which engages another portion of the second bearing on the support in response to disengagement of the other section from the annular component. The turret is then indexible to a different position before the cylinder and piston units effect of allow a return movement of the two sections of the turret into frictional engagement with the annular component.

摘要： A plain grinding machine wherein a grinding unit with a spindle for grinding wheels is reciprocable along the bed and is indexible about a vertical axis to transfer work holders between one or more indexible turrets or a magazine and a socket which is reciprocably mounted on the bed. The spindle of the grinding unit can further carry and rotate a clamping device for a workpiece to be treated by the internal grinding wheel of a holder which is separably secured to the socket. The clamping device can be stored in a second magazine which further serves for storage of one or more tool holders or tools. The grinding unit, the socket and each holder has clamping elements which can separably secure a holder to the socket, to the magazine or to the grinding unit. The control unit of the grinding machine transmits signals for actuation of the grinding unit when the latter is used as a manipulator to transfer holders between the socket and a turret or between the second magazine and the spindle.

摘要： A surface grinding machine wherein the spindle for grinding wheels is mounted on a slide which is reciprocable to and from a tool changing station. A transfer unit at the changing station has a head which is indexible on a base and has two aligned or crossing arms with discrete tool clamping mechanisms. Each clamping mechanism can accept a tool from the spindle in such orientation that the axis of the tool is horizontal, and the head is then indexed to change the orientation of the axis of the tool from horizontal to vertical before the tool is deposited in a selected carrier of a depository for tools. The depository is movable relative to the tool changing station to place a selected carrier into proper position for reception of a tool or for removal of a tool therefrom and/or to move the depository to and from a magazine for tools.

摘要： The tailstock of a universal grinding machine has a lower part which is affixed to the frame at a level below the indexible head for a set of grinding spindles, and an upper part which supports one or more dead centers and is indexible relative to the lower part about a horizontal axis extending at right angles to the axis or axes of the center or centers. The upper part of the tailstock has several facets and the number of such facets exceeds the number of dead centers by at least one. Each center is mounted on a discrete facet and the unoccupied facet is indexed to a position below the material removing station of the grinding machine when the head is to be indexed whereby the center or centers on the upper part of the tailstock cannot interfere with movements of the selected grinding wheel to and from the material removing station. The head can support a grinding wheel for removal of material from cylindrical external surfaces of workpieces, a grinding wheel for removal of material from cylindrical internal surfaces of workpieces, and a grinding wheel for removal of material from flat surfaces.

摘要： The periphery of a selected crankpin is ground while the crankshaft rotates about an axis which is parallel to the axis of the crankpin. The decreasing diameter of the crankpin is monitored by one or more sensors which are connected with a detector serving to transmit signals to the controls of the grinding machine. Retention of the sensors in continuous contact with the circulating crankpin is ensured by an elongated guide which supports the sensors and the detector and is mounted on the piston rod of a cylinder. The latter is pivotable in a holder which is reciprocably or fixedly secured to the table or to the understructure of the frame of the grinding machine. A coil spring in the cylinder biases the piston and the piston rod in a direction to maintain the forward end of the guide in continuous contact with the periphery of the circulating crankpin.

摘要： A cam grinding machine wherein the slide which supports the grinding wheel need not support the motor which rotates the grinding wheel so that the inertia of the slide is low and the slide can be reciprocated toward and away from the rotating workpiece at a high frequency, without risking the development of sympathetic vibrations, in order to account for changes in the angular position of the workpiece and, if necessary, also for wear upon and for dressing of the grinding wheel. The motor for the grinding wheel is mounted on a carriage which supports the slide or is mounted on the bed of the grinding machine next to the slide for reciprocatory movement toward and away from the workpiece.
