A grinding apparatus grinds a workpiece by rotating the workpiece held by main spindles and a grinding wheel held by a wheel spindle, and by relatively moving the grinding wheel toward and away from the workpiece. The grinding apparatus includes a first detection unit that detects a rotational phase of the workpiece; a second detection unit that detects a grinding resistance moment at a grinding point between the grinding wheel and the workpiece, or detects a drive current of a rotary drive unit of the workpiece or a rotary drive unit of the grinding wheel; a storage unit that stores the grinding resistance moment or the drive current in a manner associated with the rotational phase; and a determination unit that determines a slip between the workpiece and the main spindles based on the grinding resistance moment or the drive current at a current rotational phase, and on the grinding resistance moment or the drive current at the same phase as the current rotational phase of a previous time.

A clamping device (1) for holding a workpiece (10), in particular a cutting tool, during machining in a grinding machine, wherein peripheral grinding of the workpiece (10) is performed by means of a particularly approximately cup-shaped grinding wheel, wherein the clamping device (1) comprises a support unit (40) provided to be mounted on the grinding machine, a clamping unit (20) comprising a clamping anvil (12) supported in a clamping anvil holding element (22) and translationally drivable to apply a clamping force parallel to a clamping axis (16), and a drive unit (30) comprising a drive anvil (14) supported in a drive axis (18) and rotationally drivable for rotary orientating the workpiece (10) by means of the drive axis (18). The clamping unit (20) and the drive unit (30) are provided as individual components, which are releasably or slidably attached to the support unit (40) to form a workpiece spindle headstock of the grinding machine.

A tank polishing system for polishing a tank, the system includes a polishing cell housing a body polishing station and an end polishing station; an input window leading into the polishing cell; an output window leading out of the polishing cell; a robot having an arm with one or more vacuum cups to releasably secure to the tank via vacuum pressure, the robot housed within the polishing cell and to transfer the tank from the input window, to the body polishing station, to the end polishing station, and to the output window; a body polishing machine to polish the tank at the body polishing station; and a control system to receive user commands to operate the robot and the one or more polishing machine.

Described is a method for grinding workpieces, which comprise at least one cylindrical and profiled portion each, on one and the same grinding machine. The workpiece is ground initially in a first grinding operation in a first clamping in the grinding machine, said first grinding operation being followed by a second grinding operation once the first clamping has been released and then, before the start of the second grinding operation, a second clamping has been generated.

A tool head for a gear cutting machine includes a first spindle unit having a first spindle shaft and a second spindle unit having a second spindle shaft. A tool is axially receivable between the first spindle shaft and the second spindle shaft. A balancing device is associated with each spindle unit. The balancing device radially surrounds the respective spindle shaft and is axially arranged between a tool-side spindle bearing of the corresponding spindle unit and the tool-side end of the corresponding spindle shaft. The tool is axially clamped between the two spindle shafts by a pull rod and a clamping element.

A method and a grinding machine to implement the method includes, in a single clamping, a machine part is ground. The part is clamped on its ends and has an internal recess for grinding. The internal recess is ground with an internal grinding wheel, wherein the part is rotated between a workpiece headstock and a tailstock, and an external contour is ground by means of a grinding wheel. The part is held on the tailstock by a hollow tailstock sleeve, on the end region of the internal recess, and the internal grinding wheel passes through the hollow tailstock sleeve during grinding. In the grinding machine, a separate grinding spindle head carrying the internal grinding wheel can be included in the region of the tailstock, and can be advanced against the peripheral surface of the internal recess by passing through the hollow tailstock sleeve and the hollow center.

An apparatus for machining a cylindrical workpiece has a hollow spindle with a driving center on its tip end. The hollow spindle is rotationally journaled within a spindle unit. A tail stock spindle, with a centering center on its tip end, is rotationally supported and axially movable within a centering unit. A shaft-like kelly is non-rotationally and axially movably supported within an inner bore of the spindle. A drive rotates the spindle. Cylinders axially drive the kelly and the tail stock spindle, respectively. The spindle, the tail stock spindle and the cylinders are arranged on the same axial line. The cylindrical workpiece is sandwiched between the driving center and the centering center. An outer circumferential surface of the workpiece is finish machined while rotating the workpiece under a condition where the kelly engages the workpiece within an inner bore of the workpiece.
