Abstract

The invention relates to a device for grinding rollers (6), also for grinding hollow rollers. As the rollers tend to vibrate transversally as a result of the contact with the grinding disc (13), a cushioned body (15) is applied to the opposite side of the roller from the grinding disc (13), said body being engaged pneumatically against the roller (6) 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 pressurised medium. The engagement pressure of the cushion is adjustable. This is achieved by a pneumatic advance cylinder (17) located on a base (16), said cylinder having a piston that can be impinged on both sides (18) and that bears on its piston rod (19) a fixing plate (20) comprising the elastic cushion (15). The advance cylinder (17) is connected to compressed air conduits (21, 22), P indicating the conduit comprising a pressure regulator and L indicating the return conduit in the standard case. The invention thus provides a device (14) for damping vibrations, which suppresses any regenerative chatter and guarantees a grinding pattern that is devoid of chatter marks.

Method for grinding the exterior circumference of a rotating roller (6), held at its ends, with a rotating grinding wheel (13), whereby the length of said roller (6) is a multiple of the width of said grinding wheel, characterized in that during grinding at least one cushioned body (15, 23, 26, 34, 39, 40, 41) made of an elastic solid material or an elastic exterior skin filled with an elastic pressure material is positioned in the circumferential region opposite said grinding wheel (13) against said roller (6) to be ground.
2. Method in accordance with claim 1, characterized in that it is performed as longitudinal grinding, whereby said rotating grinding wheel (13) and said rotating roller (6) are moved relative to one another in the longitudinal direction of said roller (6) against its exterior circumference.
3. Method in accordance with claim 2, characterized in that said roller (6) is rough-ground and finish-ground successively in a single instance of chucking, each with a ceramic-bound CBN grinding wheel (12,13) and said cushioned body (6) [sic] is used at least during re-grinding.
4. Method in accordance with any of the preceding claims, characterized in that said cushioned body (15) is positioned elastically flexible against said roller (6).
5. Method in accordance with any of the preceding claims, characterized in that the positioning force with which said cushioned body (15) is positioned against said roller (6) is adjustable and can even equal a value of 0 prior to the beginning of the grinding process.
6. Method in accordance with any of the preceding claims, characterized by pneumatic positioning of said cushioned body (15) against said roller (6).
7. Method in accordance with any of the preceding claims, characterized in that at least one cushioned body is positioned during grinding at a location that remains the same in the longitudinal extension of said roller.
8. Method in accordance with any of the preceding claims, characterized in that said at least one cushioned body (15) and said roller (6) are moved relative to one another parallel to the longitudinal direction of said roller (6) during the grinding process.
9. Method in accordance with claim 8, characterized in that said cushioned body (15) is moved radially essentially opposite said grinding wheel (13) with this relative to said roller (6).
10. Method in accordance with any of the preceding claims, characterized in that said flexible cushioned body (15, 23, 26, 34) conforms to the cylindrical contour of said roller (6) when positioned against it.
11. Method in accordance with claim 10, characterized in that this conforming occurs in that a pressure medium, in particular a gas, acts on the exterior skin of said cushioned body (23, 26, 34) positioned against said wheel (6) to be ground.
12. Method in accordance with any of the preceding claims, characterized in that a liquid or gaseous lubricant is fed to the location at which said flexible cushioned body (26, 34) is positioned against said roller (6).
13. Method in accordance with claim 12 referring back to claim 11, characterized in that said lubricant is formed by said pressure medium of said cushioned body (34) and fed to the position location through apertures (35) that are situated in the exterior skin of said cushioned body (34) facing said roller (6).
14. Method in accordance with any of the preceding claims, characterized in that said cushioned body is adjusted transverse to said roller such that said roller bends outward during the grinding process and due to the grinding in its final state said roller has a longitudinal contour with a slightly concave or convex curve.
15. Method in accordance with any of the preceding claims, characterized in that the positioning force of said at least one cushioned body is changed during the grinding process and/or is adjusted to different values for a plurality of cushioned bodies (39, 40, 41).
16. Method in accordance with claim 15, characterized in that the change in the positioning force occurs depending on the axial region of said roller on which said grinding wheel and/or said cushioned body are acting at that moment.
17. Apparatus for external grinding of rollers (6), in particular for performing the method in accordance with claims 1 through 16, with tension and drive members for chucking said roller (6) at its end faces and for rotationally driving said roller (6) with at least one grinding spindle (11), driving a grinding wheel (13), that can be driven in a direction running transverse to the longitudinal axis of said roller (6) so that said grinding wheel (13) can be positioned against said roller (6), with drives for mutual longitudinal displacement of roller (6) and grinding wheel (13), and with at least one device (14) that is situated in a circumferential region of said roller (6) opposite said grinding wheel (13), through which device a cushioned body (15, 23, 26, 34, 39, 40, 41) made of an elastic solid material or an elastic exterior skin filled with an elastic pressure medium can likewise be positioned transverse to the longitudinal direction of said roller (6) against its circumference.
