摘要： A grinding machine and a method for grinding large crankshafts are disclosed. During pre-grinding, steady-rest seats are ground, and a plurality of steady rests are placed against them. Synchronous electric drives drive the crankshaft at both ends. A desired shape is produced by interpolating motion of a first grinding disk about CNC-controlled X and Z axes and about a WK pivot axis. The grinding disk is a CBN grinding disk with a width less than the axial length of the main journals and crankpins of the crankshaft. Diameters are measured along the axial length of the main journals and/or crankpins by an in-process device. The drives for the X1, Z1, and WK axes are controlled in an interpolating manner on the basis of the measurements to achieve the desired shape.

摘要： 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.

摘要： A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.

摘要： The invention relates to a method and a cylindrical grinding machine for centerless cylindrical grinding. According to the invention, the workpiece is supported on a first contact surface (7) and a second contact surface (9). The first contact surface (7) and the second contact surface (9) are arranged at an angle to each other in the manner of a prism. The grinding disk (3) is applied to the workpiece (1) with a certain application force F, whereby the workpiece (1) in turn is pressed into secure contact against the first contact surface (7) and the second contact surface (9). The two flat contact surfaces (7) and (9) cause braking of the workpiece (1), which is rotationally driven solely by the grinding disk (3). The braking reduces the rotational speed of the workpiece (1), such that the grinding disk (3) causes grinding in addition to the rotational driving of the workpiece (1). The workpiece rotational speed can be precisely set by means of an additional brake (11), which applies an adjustable braking force P to the workpiece (1).

摘要： In an apparatus for multiple-bearing grinding of workpieces, such as crankshafts, wherein a support element seat occurs at a bearing point at the same time as the grinding of the main bearing, a grinding-supporting unit is used that contains a grinding spindle head having at least one grinding disk and support elements in the form of support jaws or support bodies that can be swiveled in. After the support point seat is ground, the support elements are brought into contact there-with and support the workpiece during the further machining. The simultaneous grinding of the support point seat and several, bearing points results in a reduction in the machining time in the grinding of the workpiece compared to the prior art.

摘要： A grinding center for the simultaneous grinding of a plurality of main and rod bearings and/or central and end-side sections of crankshafts includes first and second stations. Two main bearing grinding spindles, of which the first is movable only in the Z-direction and the second only insignificantly movable in the X-direction, are mounted on a common rod bearing-compound slide. In the final phase of grinding, a correction of variations in size between the two processed rod bearings occurs via a separated drive of the second rod bearing-grinding spindle in accordance with a size or roundness correction. The variations are detected by measuring devices. An inclined profiled grinding wheel is provided for the grinding of the end sections.

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 which can be rotated about an axis and is provided with a control cam. The control cam 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 is selected from the control cam. The area is mechanically, optically, or electronically scanned by means of a scanning device. To this avail, the cam disk performs an oscillating rotary movement only above the selected section of the control cam. 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.
摘要翻译：在现有技术中，根据旋转的凸轮盘执行的额外的径向向内运动被赋予在研磨盘上，以便对切割齿和螺纹的倒角和螺纹成形器的切割齿进行减压磨削。本发明涉及一种凸轮盘，该凸轮盘可围绕一个轴线旋转并设置有控制凸轮。控制凸轮形成一组曲线，根据挖掘机或螺纹成型机的研磨齿上的大量可能的底切轮廓而形成一组曲线，这些轮廓将被释放。为了在切割齿上获得特定的底切轮廓，从控制凸轮中选择有限的旋转角度。该区域通过扫描装置进行机械，光学或电子扫描。为了获得这种效果，凸轮盘仅在控制凸轮的选定部分上方进行摆动旋转运动。一旦进行了前后移动，就完成了切削齿的浮动磨削，并且研磨盘返回到其起始位置。通过信号线将扫描结果发送到电子控制装置。

摘要： The invention relates to a device for grinding rollers, also for grinding hollow rollers. As the rollers tend to vibrate transversally as a result of the contact with the grinding disc, a cushioned body is applied to the opposite side of the roller from the grinding disc, said body being engaged pneumatically against the roller and adapting at least partially to the contours of the roller. The cushioned body consists of an elastic solid material or an elastic external skin that is filled with an elastic pressurized medium. The engagement pressure of the cushion is adjustable. This is achieved by a pneumatic advance cylinder located on a base, said cylinder having a piston that can be impinged on both sides and that bears on its piston rod a fixing plate comprising the elastic cushion. The advance cylinder is connected to compressed air conduits, P indicating the conduit comprising a pressure regulator and L indicating the return conduit in the standard case. The invention thus provides a device for damping vibrations, which suppresses any regenerative chatter and guarantees a grinding pattern that is devoid of chatter marks.

摘要： The invention relates to a method for producing gear plates (1) for a continuously variable gearbox wherein at least two gear plates (1) with the transmission surfaces (2) thereof are arranged in an opposite mauler. When the gearbox is in operation, said transmission surfaces come into contact in a non-positive mode with a power transmission element, on a device comprising at least one workpiece spindle (3) and a grinding disc (4) which is driven by a grinding spindle (5) in order to grind the transmission surface (2) of at least one gear plate (1). During the grinding of the transmission surface (2), a repeated relative oscillating movement is carried out radially in relation to the workpiece spindle (3), between the grinding disc (4) and the gear plate (1), in such a way that the grinding region of the grinding disc (4) is moved back and forth between an inner radius (2.1) and an outer radius (2.2) of the transmission surface (2). The gear plate (1) is rotated by means of the workpiece spindle (3) in such a way that the entire transmission surface (2) is ground.
