Definitions
- the invention relates to a method for finish machining peripheral surfaces of rotationally symmetrical workpiece sections and to a device suitable for carrying out the method.
- Finishing which is also referred to as superfinishing, is a machining process with indefinite cutting edges.
- workpieces such as crankshafts, camshafts, transmission shafts or other components for power and working machines can be edited to produce a desired surface fine structure.
- a finishing tool with granular cutting agent is pressed against the peripheral surface to be machined.
- the workpiece is rotated about its workpiece axis. At the same time, a relative movement that oscillates parallel to the workpiece surface is produced between the workpiece and the finish tool resting against the peripheral surface.
- the workpiece section to be machined may be, for example, a main bearing or a crank bearing of a crankshaft or a camshaft bearing.
- finishing is a thermally neutral processing method in which no soft skin interspersed with microcracks or surface tensions arises. Finishing is often used after a grinding process as the last machining process of a process chain to remove the soft skin, re-exposing the original microstructure, increasing the support of the roughened surface structure, and improving the component geometry in terms of roundness and shortwave errors in the axial and circumferential directions.
- Grinding is the last shaping machining operation.
- the geometry of the grinding tool of the machine control is known, so that the workpiece can be contoured by grinding according to the guided by the machine control tool guide.
- a prerequisite for this shaping is the regular dressing or calibration of the grinding tools.
- the grinding process is usually unable to achieve the achievable by the finish machining surface properties.
- the preservation of the axial contour is usually in the foreground.
- An improvement in the form values on cylindrical bearings takes place mainly in the radial direction and is highly dependent on the pre-processing.
- short-wave error components e.g. with more than 15 waves on the circumference
- long-wave components such as e.g. Ovals, triangles or quadrilaterals can not be positively influenced by finishing.
- the cutting volume through the finishing process is usually below about 10 ⁇ .
- the material removal of the finishing process is normally adjusted to the pre-processing.
- Grinding is usually the last shaping machining operation. This means that the contouring of a rotationally symmetrical bearing point essentially takes place through the grinding process preceding the finishing process.
- a continuous dressing of the grinding wheel is imperative for the shaping and design of the bearing. Depending on the requirement and the drawing tolerance of the bearing, the dressing cycle is reduced or extended. However, the grinding process is usually not able to achieve the achievable by the finish machining surface properties.
- a crowned (barrel-shaped, convex) shape of rotationally symmetric bearing sections can help to reduce bearing damage due to flight and form errors of the components interacting in the bearing.
- specified by the customer final generatrix requirements regarding crowning are usually expressed in diameter differences of a few micrometers between different axial positions of the bearing section.
- FIG. EP 1 514 642 A2 describes a device for finish machining of shafts, in particular crankshafts and camshafts, with a tool carrier and an endless grinding belt, which has a flexible carrier and an abrasive layer with hard material.
- the device is used for processing a rotating about its axis of rotation workpiece.
- a sanding belt drive continuously drives the sanding belt during workpiece machining.
- the tool carrier has a machining head with two mutually spaced band deflections, which limit a working range of the machining head, wherein the grinding belt is guided over the tape deflections and passes in the work area on the peripheral surface of the workpiece to be machined.
- the circulating abrasive belt outside of the work area is associated with a device for dressing the abrasive layer, which has a deliverable during the workpiece processing against the abrasive layer of the belt at a speed adjusted to the workpiece processing belt speed adjustable dressing tool.
- the dressing tool has a convex contour transverse to the direction of tape travel, which is transferred to the abrasive layer during dressing. As a result, a slightly convex contour can be generated on the machined workpiece section.
- the possibility should be created to produce non-cylindrical workpiece sections with predefinable spherical shape by means of finishing.
- the invention provides a method having the features of claim 1. Furthermore, an apparatus suitable for carrying out the method with the features of claim 5 is provided. Advantageous developments are specified in the dependent claims. The content of all claims is incorporated herein by reference.
- the finishing tool or the decisive for the material removal provided with cutting means part of the finishing tool during a linear linear motion parallel to the axis of rotation of the workpiece imposed on this linear motion pivotal movement, so that the abrasive part of the finishing tool is guided along an at least partially curved tool path.
- different, axially juxtaposed axial sections on the machined workpiece section can be finishen specifically with different degrees of material removal, whereby a desired, in the axial direction not rectilinear generating line form can be selectively generated.
- the generatrix shape can thus be changed by means of a special machine configuration with respect to the generatrix line resulting from the preprocessing.
- a shaping processing by Finishen is possible.
- control of the machine is carried out so that in a final phase of a linear stroke of the linear machine axis leading in the direction of movement of the linear motion leading end portion of the finishing tool closer to the workpiece axis and / or is pressed with higher local contact force to the peripheral surface than a trailing rear end section.

- a robust and reliably working variant of a device is characterized in that the translatory machine axis has a horizontal slide comprising a rotary machine axis with a rotary table which relative to the carriage by means of a numerically controlled rotary drive, for example a servomotor, corresponding to one of the pivot axis horizontal axis of rotation is rotatable.
- the rotary table may carry a stone guide having a translatory machine axis to move the tool holder along a feed direction which is perpendicular to the pivot axis and corresponds to the pressing direction.
- machine axes in other ways, for example by providing a rotary machine axis with a rotary table carrying a linear guide for a translatory machine axis.
- the rotary axis is realized as an integrated into the finish tool axis, that is located on the tool side of the tool holder. This also makes it possible to achieve that the abrasive cutting means along the desired arcuate gene career is positively driven, for example, to generate a spherical shape on the workpiece section.

- the additionally achievable by the linear movement stroke can be in the same order of magnitude, that is, for example, between 1 mm and 3 mm. Other stroke lengths and stroke length ratios are possible.
- the axis-parallel linear movement is superimposed on a pivoting movement of the finishing tool about a perpendicular to the linear direction and perpendicular to the pressing direction pivot axis.
- the pivoting movement is controlled so that in an end phase of a Linearhubs, ie in the second half of a Linearhubs after exceeding a central position, according to a control program in the direction of movement of the linear motion vorseilender front end portion of the finish tool is closer to the workpiece axis 192 or is pressed against the peripheral surface with a higher local pressure force than is in the motion Direction lagging rear end portion.
- the finish tool moves leftward in the first direction R1 in FIG. 3, the front end portion E1 is pressed against the workpiece surface with a stronger local pressing force than the trailing second end portion E2.
- the pressing direction is oriented perpendicular to the workpiece rotation axis and both end sections of the finishing tool are pressed against the peripheral surface with approximately the same local contact pressure

- 4A shows a side view parallel to the direction of movement of a horizontal, linear machine axis, which executes the linear stroke.
- 4B shows a front view of the device in a horizontal direction perpendicular to this linear direction, which corresponds to the axial direction of a rotary machine axis.
- a linear machine axis LA is provided with a horizontal axis direction. Through this, the described linear motion is generated.
- the linear machine axis includes a horizontal slide 420, which is guided along horizontal guide rails 425 and is moved by means of a servo motor (not shown) via a ball screw.
- the carriage 420 carries a rotary machine axis, which comprises a rotary table 430 which can be rotated relative to the carriage 420 by means of a numerically controlled rotary drive about a horizontal axis of rotation corresponding to the pivot axis SA.
- the rotatable about the pivot axis rotary table 430 carries on its front side a so-called stone guide 440 which includes a translational machine axis to move the tool holder 180 along a direction perpendicular to the pivot axis SA extending feed direction, which corresponds to the pressing AR.
- Attached to the front end of the tool holder is the finish tool 100, which processes the workpiece 190 which is driven for machining by means of a rotator to rotate about its workpiece rotation axis 192 at a predetermined speed (eg, between 50 min -1 and 300 rpm ) min "1 turns.
- the device can work as follows. While the workpiece 190 is rotated about the workpiece axis 192, the finish tool 100 performs a rapid oscillation in the oscillation direction OR along the movement axis of the oscillator. In addition, an interpolating movement is superimposed by the stone guide to the finishing tool to produce an axial geometry of the machined workpiece section.
- the stonecutter For this purpose along the horizontal direction of movement of the linear axis LA performs a relatively slow and large stroke.
- the rotary table 430 pivots the stone guide 440 about the pivot axis SA, while the linear axis, which can move the tool holder 180 linear, causes a corresponding length compensation. In this way, an arcuate tool path is imposed on the finish tool. This can be produced by finishing a round or any other axial tool path on the machined workpiece section, whereby a corresponding generatrix line shape can be generated on the workpiece.
- a high oscillation frequency of the oscillation movement (typically at least 10 Hz) parallel to the axial contour ensures a self-sharpening effect of the finish tool, so that a dressing of a finish tool unlike grinding tools is not required.
- the process chain can be significantly reduced and investments can be saved.
- the rotary pivot axis is a machine axis
- the finish tool is a conventional passive finish tool.
- the pivoting movement or a corresponding pivot axis can be integrated into an actively activatable finish tool.
- 5 shows an example of a finishing tool 500 with integrated pivot axis.
- the cutting medium carrier 510 of the finishing tool 500 is constructed in several parts.
- a machine-side fixed part 512 is fixed with suitable fasteners on the tool carrier 1 10.
- the fixed part carries a relative to the fixed part of the movable part 514, which is opposite to the fixed part by a Swivel axis SA is limited pivot.
- the cutting pad 520 is attached to the front of the movable part 514.
- the pivotal movement of the movable part with cutting surface with respect to the fixed part is accomplished by means of actuators ACT, which may be constructed using piezo elements, for example.
- the actuators are controlled via the control unit of the finishing device and cause a pivoting of the movable part relative to the fixed part in dependence on the linear movement of the translational axis parallel to the workpiece rotation axis.
- the movable part 514 with the cutting pad 520 can be considered as a finishing tool, while the fixed part 512 can be considered as part of the tool holder 180.
- the variant of FIGS. 1, 2 and 4 then differs from the variant from FIG. 5 in that in the first case the pivot axis is arranged on the machine side of the tool holder and in the latter case on the tool side of the tool holder.
