摘要： The housing (28) of a grinding spindle unit is pivotably mounted by way of a pivot axle (26) on the receiving part (21) of a grinding machine, e.g. on a grinding headstock. The grinding spindle unit bears a grinding wheel (31) which is driven in rotation. The actuation of an adjusting unit (33) extends a pressure pin (34), which pivots the housing (28) of the grinding spindle unit about the pivot axle (26) and thus slants the grinding wheel (31). The pivot axle (26) is in this case formed as a film hinge through a zone of targeted elastic material deformation. A tensile spring device (38) brings about constant contact between the pressure pin (34) and the receiving part (21). The arrow of rotation (36) denotes the pivoting direction and (37) denotes the angle by which the grinding spindle unit slants with respect to the receiving part (21). The axis of the rotating workpiece (not shown) is denoted by (22).

摘要： In prior art, an additional radial inward movement that is performed in accordance with a rotating cam disk is imparted on the grinding disk in order to relief-grind the cutting teeth and the chamfer of taps and the cutting teeth of thread formers. The invention relates to a cam disk (11) which can be rotated about an axis A and is provided with a control cam (12). Said control cam (12) forms a group of curves according to a large number of possible undercut contours on the grinding teeth of the tap or thread former, which are to be relief-ground. In order to obtain a specific undercut contour on a cutting tooth, a limited angle of rotation α is selected from the control cam (12). Said area is mechanically, optically, or electronically scanned by means of a scanning device (13). To this avail, the cam disk (11) performs an oscillating rotary movement only above the selected section of the control cam (12) (arrow indicating the direction of rotation 15). Relief-grinding of the cutting tooth is completed once a fore-and-aft movement has been performed, and the grinding disk returns to the starting position thereof. The result of the scan is transmitted to an electronic control device via a signal line (14).

摘要： The invention relates to a method for grinding convex running surfaces and exact outside diameters on undulated workpieces (10). In a clamping, a first convex running surface (36) is ground on a discoid partial section of an undulated workpiece (10) during a first grinding operation while using a first grinding wheel (33) that comprises at least one concave lateral surface (35). A second grinding wheel (34) is used to grind a desired outside diameter on the discoid partial section as well as on other partial sections of the undulated workpiece (10) during a second grinding operation.

摘要： The present invention relates to a method for grinding a centrally clamped crankshaft (1). The invention also relates to a grinding machine (43) for crankshafts for carrying out said method and a crankshaft (1) consisting of high-alloy steel or cast. According to the inventive method, lifting bearings (12) and main bearings (11) of the crankshaft (1) are ground in a clamping in such a way that at least the main bearings (11) are rough-ground and subsequently the lifting bearings (12) and then the main bearings (11) are finish-ground. The grinding machine (43) for crankshafts forms a working centre by means of which corresponding rough-grinding and finish-grinding are possible in one single clamping.

摘要： The invention relates to a method for machining workpieces with areas which comprise form variations, whereby the workpiece (5) is fixed between the tip (13) of the tool spindle (30) of the workpiece spindle head (1) and the tip (6) of the sleeve (13) of the tailstock (3), and a backrest seat (8) is ground on the workpiece (5). The tip (6) of the sleeve (13) of the tailstock (3) sits closely in the center of the receiver of the workpiece. The method is characterized in that the tip and the tailstock sleeve are retracted from the contact area, said contact area being located in the center of the clamping of the workpiece, to an intermediate position after the backrest seat has been ground. In addition, the workpiece is positionally fixed on the side of the tailstock by a backrest (7) and by an axial force which is applied via a prestressed pressure pin (21) and which is directed against the center of the clamping of the workpiece.

摘要： What is described is a method and a grinding machine for implementing the method, in which a machine component (2) to be machined which is clamped at its two ends (3, 5) and has an internal recess (6) to be ground is ground in a single set-up. The internal recess (6) is ground by an internal grinding disc (8), wherein the machine component (2) is held so as to be rotationally driven in its set-up between a workpiece headstock (9) and a tailstock (10) and is additionally ground on its external contour (17) by means of a grinding disc (16). The machine component (2) is held in a centring manner on the tailstock (10) by a tailstock hollow sleeve (15) with a hollow centre (20) at the end region of the internal recess (6), wherein the internal grinding disc (8) engages through the tailstock hollow sleeve (15) and the hollow centre (20) during the grinding of the internal recess (6). In the case of the grinding machine according to the invention, a separate grinding headstock is preferably provided in the region of the tailstock (10) and bears the internal grinding disc (8), which in turn can be advanced to the circumferential surface of the internal recess (6) by engaging through the tailstock hollow sleeve (15) and the hollow centre (20).
