Definitions
- the invention relates to a method for grinding a workpiece with the features according to the preamble of claim 1 and a device for carrying out the method with the features according to the preamble of claim 4.
- Finishing and finishing are usually two successive operations on two specially designed machine tools.
- the disadvantages here are that on the one hand the number of different machine tools increases to a large extent the investment required to produce a particular component and that on the other hand the manufacturing costs for the component in question are also increased by longer throughput times with intermediate transport operations.
- Another disadvantage is that the renewed clamping can occur in the machine tool realizing the fine machining, which proves to be disadvantageous for the required manufacturing tolerances.
- Precision machining processes include honing in particular. Honing is a cutting process with bound grain to improve or change the shape, dimensional accuracy and surface quality of the workpiece, whereby the tool is constantly in contact with the surface of the workpiece. Honing is generally used after finishing, such as grinding, for finishing.
- the so-called short stroke honing is also referred to as fine honing, finish machining or superfinishing, fine drawing grinding or oscillating grinding.
- Machine tools for grinding and machine tools for example for superfinishing are known (see company brochure IMPCO Machine Tools, USA, 1994).
- IMPCO Machine Tools USA, 1994.
- the concept of two different machine tools for fine machining and fine machining also requires considerable development effort.
- the invention is therefore based on the object of providing a method and a device for machining workpieces by means of which the geometry of the workpiece is machined true to size and shape, provided with the required surface quality and the production time and thus the unit cost of the workpiece considerably be reduced.
- the workpiece is clamped for processing and the geometry of the workpiece ground to size and shape.
- at least part of the surface of the workpiece is at least partially finely machined parallel to the grinding. Finishing is preferably carried out by finishing.
- the grinding and the fine machining are carried out on cylindrical and / or conical surface sections of the workpiece.
- the device used for carrying out the method according to the invention for grinding a workpiece is used in particular for grinding shaft parts, for example a gear.
- the device has a workpiece headstock and tailstock for clamping the workpiece and a grinding unit.
- the grinding unit is provided with at least one grinding spindle, which carries a grinding wheel for grinding the workpiece.
- the workpiece headstock and the tailstock and / or the grinding unit are arranged so as to be able to achieve a grinding relative movement, which produces the desired workpiece geometry, between the grinding unit and the workpiece in a controlled manner.
- the device is provided with a micromachining unit which can be moved in accordance with the geometry of the workpiece, at least part of the surface of the workpiece being microfinishing by means of the micromachining unit.
- the grinding unit and the finest machining unit are movable in such a way that they are at least temporarily engaged with the workpiece at the same time.
- the grinding unit and the ultra-fine machining unit are preferably arranged essentially opposite one another with respect to the longitudinal axis of the workpiece, so that the workpiece is clamped between the two machining units.
- This has the advantage that there is free movement of both the grinding unit and the finest machining unit without mutual hindrance.
- simultaneous grinding and ultra-fine machining of the workpiece can take place essentially over the entire length of the workpiece.
- the grinding fineness ⁇ and Feinstbear mecanicngsech preferably with respect to the work piece ⁇ longitudinal axis substantially on a side of the workpiece to arrange. This is advantageous, for example, if only part of the surface of the workpiece must be finely machined and the length of the workpiece to be machined is long enough so that the fine machining unit and grinding unit do not interfere with one another during simultaneous engagement with the workpiece.
- the grinding unit has a carrier on which two grinding spindles, each with at least one grinding wheel, can be pivoted and are mounted on a common infeed axis such that the grinding wheels can be brought into engagement with the workpiece one after the other.
- a grinding unit is particularly useful when different surface contours of the workpiece have to be machined with the dimensions and shape using the grinding unit.
- the fine machining unit is preferably designed as a fine grinding unit or as a finishing unit. Both the fine grinding unit and the finishing unit serve to achieve surface qualities of the workpiece or a part of the surface of this workpiece, which are in the range of the manufacturing processes usually referred to as fine machining.
- FIG. 1 shows a schematic top view of the device according to the invention in accordance with a first exemplary embodiment:
- 2 shows a schematic top view of the device according to the invention in accordance with a second exemplary embodiment of the invention: 2a shows the engagement of a first grinding spindle of the device according to FIG. 2 on the workpiece;
- FIG. 2b shows the infeed of a second grinding spindle according to FIG. 2 as well as the finest machining unit to the workpiece
- Fig. 3 is a schematic plan view of the device according to the invention according to a third embodiment.
- a workpiece 3 is clamped between tips 20, 21 between a workpiece headstock 1 and a tailstock 2.
- the longitudinal axis of the workpiece 3 is aligned with the longitudinal axes of the spindles of the workpiece headstock 1 and the tailstock 2.
- the workpiece headstock 1 and the tailstock 2 are arranged on a movable grinding table, not shown, along a CNC axis ZI.
- a grinding headstock 23 is provided on one side of the workpiece headstock / workpiece / tailstock arrangement.
- the grinding headstock 23 has a grinding spindle 14 with a grinding wheel 15.
- the grinding headstock 23 is arranged to be movable with respect to a movement axis XI in the sense of an infeed to the workpiece 3.
- the longitudinal axis of the grinding spindle 14 can be arranged parallel or horizontally pivotable with respect to the axis of the workpiece.
- the grinding headstock 23 can also be moved in the direction of the ZI axis. In such a case, the workpiece headstock 1 and tailstock 2 are firmly mounted on the machine stand.
- a fine machining unit 25 is arranged in an essentially horizontal plane. By means of this fine machining unit 25, the surface of the workpiece 3 is reworked in accordance with the shape, tolerance and surface requirements, the fine machining being able to be carried out in parallel with the engagement of the grinding wheel 15 with the workpiece 3
- This ultra-fine machining unit 25 is provided, for example, with a superfinishing unit.
- the ultra-fine machining unit 25 can be moved along two CNC axes X2 or Z2 arranged at right angles to one another, so that it can carry out independent movements from the grinding headstock 23.
- This exemplary embodiment, in which the grinding unit 14, 15, 23 and the fine machining unit 25 are arranged opposite the workpiece, has the advantage that essentially the entire surface of the workpiece 3 is ground with the grinding unit 14, 15, 23 and, at the same time, with the fine machining unit 25 can be finely machined
- FIG. 2 shows the top view of the device according to the invention according to a second exemplary embodiment.
- a device according to this exemplary embodiment is used above all when the outer contour of the workpiece 3 has to be machined with at least two grinding wheels.

- the grinding spindle 12 of the grinding headstock 24 is in engagement with the workpiece 3 for grinding a conical shape 4 by means of the grinding wheel 5.
- both grinding headstock are
- finishing stone 9 to the workpiece 3.
- a cylindrical pin 7 is ground on the workpiece 3 using the grinding wheel 6.
- the conical surface 4 of the workpiece 3 is simultaneously subjected to a finishing process in order to increase the surface quality by means of the finishing stone 9.
- the use of such a finishing stone is particularly advantageous when high load shares are to be achieved in relation to the surface quality of the workpiece surface.
