Definitions
- the present invention relates to a method for processing rotary parts comprising at least one working step in which a grinding of at least one surface of the workpiece clamped in a device takes place.
- a method for processing rotary parts comprising at least one working step in which a grinding of at least one surface of the workpiece clamped in a device takes place.
- Such a method is for example from the document DE-A1-43 29 610 known.
- the object of the present invention is to simplify a method for processing rotary parts of the aforementioned type, to reduce manufacturing costs while achieving a high process reliability to obtain workpieces of high quality standard.
- the solution to this problem provides a method according to the invention for the machining of rotary parts of the aforementioned type with the features of the main claim.
- at least one front-side bore is introduced into the workpiece clamped for the grinding operation in the same clamping device by means of a drilling tool.
- a new clamping of the workpiece in a dedicated special machine with its own work sequence is thus no longer necessary.
- the drilling for example, the introduction of a front-side fitting bore in a rotary part, for example in a crankshaft flange takes place in the same clamping device, in which also the grinding process takes place. This can be done in a suitable clamping device.
- the workpiece can be clamped at least in each case at both ends in a clamping device and, for the drilling process, release the clamping device at at least one end and arrange there a chuck for a drilling tool, which then performs the desired frontal bore.
- at least one fine bore or precision bore is introduced into the workpiece on the front side.
- a suitable guide element such as a guide bezel.
- the grinding operation performed on the tool in the chuck preferably comprises at least one CBN grinding by means of a grinding wheel.
- crankshafts are usually produced independently of the power class with a high production cost.
- the ball bearing almost all crankshafts are rotated and rolled by a separate machine or sequence.
- this sequence of operations of turning and deep rolling the ball bearing can be omitted and replaced by grinding the ball bearing.
- This grinding of the pivot bearing can be done for example in the already made operation of the flange-pin grinding. In this way, the manufacturing costs in the production of such rotating parts, in particular crankshafts, can be significantly reduced.
- crankshafts the state of the art usually involves finish machining, regardless of the requirements of the crankshaft.
- main, stroke bearings, flange and pins of the crankshaft are polished.
- This polishing operation can be dispensed with according to an embodiment of the invention and replaced by a suitable grinding operation, in particular by CBN grinding.
- a suitable grinding operation in particular by CBN grinding.
- roughnesses of, for example, on the order of about 2 ⁇ m can be achieved.
- R z even more subtleties can be achieved for R z , for example, when problems occur in the area of an oil passage, a groove in the bearing or the like. If the finish machining of the rotary component, in particular in the case of crankshafts, is eliminated, this likewise leads to a further considerable reduction in the production costs.
- FIG. 1 The diagram shows schematically greatly simplified a machine for machining of rotating parts, in particular crankshafts.
- This machine comprises a first drive unit 17, and a second drive unit 16, so that it is possible to machine the rotary part 10 from both ends.
- a clamping device comprising a first chuck 11 for clamping the rotary member 10 at its one end and a second chuck 12 for clamping the rotary member at its other end, wherein the clamping device is designed so that by means of the drive units 16, 17 Rotation part 10 can be rotated about its axis 18.
- the machine according to the invention has a guide bezel 14, which provides for a guide or support on the circumference of the workpiece.
- Fig. 1 shows the clamped for a grinding operation crankshaft 10, which is clamped at both ends via the chucks 11, 12.
- a grinding wheel 15 can be used for the grinding process, which can be driven rotatably about an axis 19 and which can carry out a feed in the direction of the workpiece 10 by means of a suitable device 20 (see double arrow in FIG Fig. 1 ).
- FIG. 2 shows that the chuck 11 has been withdrawn, wherein the clamping elements 11 a were solved, so that at the left end in the drawing of the crankshaft 10, the original clamping is no longer given. You can see it too by comparison with Fig. 1 in that, due to the retraction of the chuck 11, there is a certain distance between the chuck 11 and the front face 21 of the crankshaft. In the specially trained chuck 11, a tool, such as a fine boring tool 13 can now be clamped, which introduces a front-side precision bore in the flange 22 of the crankshaft 10.
- the guide bezel 14 now serves in this end region for supporting the crankshaft 10.
- the clamping in the second chuck 12 remains as in FIG Fig. 1 also shown when editing with the fine boring tool 13.
- the drilling can be done simply by the feed of the fine boring tool 13.
- the fine boring tool is withdrawn, it is removed from the chuck 11 and if necessary, the crankshaft 10 can be clamped again via the clamping elements 11a for further machining operations, for example Grinding the surface or the like.
- the advantage of the method according to the invention is therefore that operations on the surface such as grinding and drilling operations in the frontal area in the same machine can be done in principle in the same clamping.
