- This grinding wheel has an abrasive coating 6, which both arranged on the front side and in a partial region of the side surface 9 is.
- this grinding wheel in terms of their width exactly the measure on which the Represents the distance between the plan shoulders at the depository. Therefore, one is Dressing the abrasive coating 6 on the side surface 9 not possible. On Dressing up would eventually cause the gauge between the Plan shoulders of a storage area would no longer be achieved. Therefore, at Such grinding wheels dressing essentially only on the Peripheral side performed.
- the dot-dash line 29 represents the contour of Grinding wheel before the dressing process.
- the dressing wheel 27 with the Diamond coating 28 around the radius in the transition area of Peripheral area is guided around the side portion of the grinding wheel. to However, maintaining the width of the one-piece grinding wheel runs that Truing measure to zero at the end of the radius of the grinding wheel.
- the Angle ⁇ of, for example, 3 ° shows the point at which in the outer radius transition of the grinding wheel the Dressing allowance 29 is reduced to 0.
- the shape conditions on Radius transition of the bearing to the plan shoulders are respected may need relative to a one-piece grinding wheel in the peripheral area a lot of abrasive when dressing are removed. Otherwise that would "Profile collapse”.
- the conditions are different when dressing an inventive Grinding wheel. This is shown in FIG. 8b). It can be seen that the Abrichtrad 27 around the entire to be dressed contour of the grinding wheel from Circumferential range over the radius range up to and including the Side area is guided around and a uniform dressing allowance away. Because in the grinding wheel according to the invention, the at Dressing removed allowance can be compensated by the width adjustment. This makes it possible to use just as much abrasive when dressing remove that the grinding wheel becomes abrasive again, smoothing in All grinding areas of the grinding wheel are thus avoided can. As a result, only the minimum allowance for dressing to remove, the grinding wheel according to the invention can significantly more often be dressed until the grinding wheel lining of the grinding wheel in Essentially completely exhausted and thus the grinding wheel becomes unusable.
- FIG. 9 shows an enlarged view of a device according to the invention Grinding tool.
- the grinding conditions in the moment in which the grinding tool with its grinding surface side surface 6C in the flat shoulder area of the workpiece 30 to be ground in the sense of a piercing process with the grinding of the shoulder just starts. Shown is only the part 5 of the grinding tool with its Abrasive coating 6A in the peripheral area and 6C in the lateral area of the outer Side surface 9 of the grinding wheel-like body. Shown is the Further, the rough contour 31 of the workpiece 30, which by means of grinding tool according to the invention on the workpiece end contour 32, which is shown as a dashed line, is ground.
- the area marked by a thick line in the transition from Edge radius of the grinding wheel on the grinding surface side surface 6C provides a grinding zone 33 in which, due to the fact that the Grinding tool and the workpiece are rotationally symmetric parts that the Removal of the largest grinding allowance, i. the up on the plan side of the Storage location, only a few abrasive grains must be made. These Abrasive grains in this lateral zone on the grinding tool are during the grinding process thereby loaded the highest. The in the radial direction of the grinding tool (ie counter to the piercing direction in the workpiece 30) underlying abrasive grains take on the actual grinding process in fact not part. The dressing cycles are therefore essentially following the wear at this point.
- FIG. 10 shows a grinding tool according to an embodiment of the invention, in which the gaps 25 between the grinding wheel parts 5 and 7 are flowed through by a coolant 26.
- the coolant is preferably fed in the axial direction of the grinding tool, which preferably under pressure.
