AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT ROLL FORM WHEEL DRESSER WITH MULTIPLE CURVATURES FOR DRESSING DIFFERENT SIZED GRINDING WHEELS The following statement is a full description of this invention, including the best method of performing it known to me Title: ROLL FORM WHEEL DRESSER WITH MULTIPLE CURVATURES FOR DRESSING DIFFERENT SIZED GRINDING WHEELS Field of the Disclosure: The present disclosure generally relates to maintenance of grinding wheels used for abrasive machining. More particularly, the present disclosure relates to a roll form wheel dresser used for knocking worn-out abrasive particles of a grinding wheel while still maintaining concentricity of the grinding wheel. Background: A grinding wheel is an expendable wheel made from a matrix of coarse, abrasive particles pressed and bonded together to form a solid, circular shape. Each of the coarse, abrasive particles of the grinding wheel acts as a cutting tool for facilitating abrasive machining. More specifically, sharp cutting edges of each of the coarse, abrasive particles on grinding wheel's surface remove small chips from a work-piece via shear deformation. In order to achieve effective grinding and satisfactory finish on the work-piece, proper selection of the grinding wheel is of primary importance. The small cutting edges of the coarse, abrasive particles on grinding wheel's surface become dull with regular use of the grinding wheel. In order to achieve a free cut and produce a satisfactory finish on the work-piece, a layer of coarse, abrasive particles with the sharp cutting edges is required to be maintained on the surface of the grinding wheel. For maintaining a layer of coarse, abrasive particles with the sharp cutting edges on the surface of the grinding wheel, dressing of the grinding wheel is required. Wheel dressing is the process of knocking worn out abrasive particles with dull cutting edges from the grinding wheel's surface and exposing fresh abrasive particles with sharp cutting edges on the grinding wheel's surface, while still maintaining the concentricity of the grinding wheel. The wheel dresser includes hard cutting points that fractures the worn out abrasive particles on the grinding wheel's surface or completely removes the worn out abrasive particles, thereby exposing fresh abrasive particles that has sharp cutting edges. The wheel dresser further cleans out tiny spaces between the abrasive particles, thereby removing metallic dust and other particles which eventually clog up pores of the wheel face and adversely effects performance of the grinding wheel. Apart from proper selection of the correct grinding wheel, selection of the proper truing or dressing tool and proper use thereof is also important. More specifically, incorrect dressing causes a satisfactory grinding wheel to act unsatisfactorily. On the other hand use of a good dressing tool can improve life and grinding action of a grinding wheel. The wheel dresser includes a plurality of hard cutting points disposed on a surface there-of, the hard cutting points rub against the grinding wheel to cause dressing of the grinding wheel. The hard cutting points of the wheel dresser functions like cutting tool and like all cutting tools the hard cutting points of the wheel dresser gets worn out and become dull with regular use of the wheel dresser. Dull cutting points of the wheel dresser crush and glaze 2 the wheel face of the grinding wheel being dressed and load the pores with wheel cuttings, thereby making the grinding wheel dull. Accordingly, the wheel dressers are required to be replaced once the hard cutting points of the wheel dresser become dull. However, most of the prior-art dressing tools are specifically designed to dress grinding wheels of a particular size only. More specifically, the prior-art dressing tools, particularly, the roll form dressing tools are in the form of a cylindrical body provided with a cavity configured thereon and extending around a periphery thereof. The cavity configured on the periphery of the roll type dressing tool has a curved profile having a curvature that facilitates receiving of a peripheral portion of a grinding wheel of a particular size. As the roll type dressing tool rotates about an axis of rotation, the cutting points disposed on the curved profile of the cavity rub against the peripheral portion of the grinding wheel to cause dressing of the grinding wheel. The cavity configured on a roll form dressing tool is able to receive peripheral portion of a grinding wheel of a particular size and the same roll form dressing tool cannot be used to dress a grinding wheel of different size. More specifically, most of the prior art dressing tools lack flexibility to perform dressing of different sized grinding wheels. Further, most of the prior art dressing tools lack capability of simultaneously performing dressing of more than one grinding wheel. Accordingly, there is a need for maintaining a large inventory of the wheel dressers corresponding to different sized grinding wheels for maintaining unhindered operations. Costs associated with maintaining such large inventories of wheel dressers are also high. There is felt a need to reduce the 3 inventory of wheel dressers and reduce the cost of manufacturing the wheel dressers. Objects: Some of the objects of the present disclosure which at-least one embodiment is able to satisfy, are described herein below: It is an object of the present disclosure to ameliorate one or more problems of the prior art or to at least provide a useful alternative. The principle objective of the present disclosure is to provide a roll form dressing tool that has multiple cavities of different curvatures for dressing grinding wheels of different sizes. Another object of the present disclosure is to provide a roll form dressing tool that has multiple cavities of same curvatures for dressing grinding wheels of a particular size. Still another object of the present disclosure is to provide a roll form dressing tool that reduces inventory of the wheel dressers. Yet another object of the present disclosure is to provide a roll form dressing tool that simultaneously performs dressing of more than one grinding wheel. Another object of the present disclosure is to provide a roll form dressing tool that is economical to use. 4 Still another object of the present disclosure is to provide a roll form dressing tool that is simple in construction. Yet another object of the present disclosure is to provide a roll form dressing tool that is robust in construction. Another object of the present disclosure is to provide a roll form dressing tool that requires less maintenance. Still another objective of the present disclosure is to provide a roll form dressing tool that maintains grinding wheels in proper working conditions.

The description provided is purely by way of example and illustration. The embodiments herein and the various features and advantageous details thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. Referring to Figure la of the accompanying drawings, a prior art roll form wheel dresser 10 is illustrated. Further, Figureib illustrates a prior art roll form wheel dresser 100 having a cavity 104 provided at a dressing portion "A" thereof for receiving a peripheral portion of a grinding wheel. Figure Ic illustrates an enlarged view of the dressing portion "A" of the form wheel dresser 100. Again referring to Figure la, the roll form wheel dresser 10 has a cylindrical body 02 provided with a cavity 04a extending around a periphery thereof. The cavity 04a is having a curvature such that the cavity 04a receives a peripheral portion of a grinding wheel of a particular size. As the roll type wheel dresser 10 rotates about an axis of rotation 06, the cutting points disposed on the curved profile of the cavity 04a rub against the peripheral portion of the grinding wheel to cause dressing of the grinding 8 wheel. Although, the wheel dresser 10 disclosed herein is used for dressing the grinding wheel used in the machining of outer track of the bearings, the wheel dresser of the present disclosure may be used for dressing of grinding wheels used in other applications. Figure 2 illustrates a schematic representation of a prior art roll form wheel dresser 150 having a cylindrical body 152 provided with a cavity 154a mounted on a rotating shaft in accordance with an embodiment. Referring to Figure 3a of the accompanying drawings, a roll form wheel dresser 20 in accordance with an embodiment of the present disclosure is illustrated. Further, Figure3b illustrates a roll form wheel dresser 200 having a pair of cavities 204a and 204b provided at a dressing portion "B" thereof, wherein each cavity 204a and 204b receives a peripheral portion of a grinding wheel. Figure 3c illustrates an enlarged view of the dressing portion "B" of the roll form wheel dresser 200. Again referring to Figure 3a, the roll form wheel dresser 20 has a cylindrical body 12 provided with two similar cavities 14a and 14b extending around a periphery thereof. The cavities 14a and 14b are similar in configuration and have equal curvatures, such that each of the cavities 14a and 14b is capable of receiving a peripheral portion of a same sized grinding wheel. As the roll type wheel dresser 20 rotates about an axis of rotation 16, the cutting points disposed on the curved profile of the cavities 14a and 14b rub against the peripheral portion of the grinding wheel to cause dressing of the grinding wheel. The cavities 14a and 14b configured on the roll form wheel dresser 20 can either be used one at a time or simultaneously depending upon requirement. When one of the cavities 14a and 14b is used for dressing the grinding wheel, the 9 cutting points disposed on curved profile of the cavity becomes dull the other cavity can be used for dressing the grinding wheel. However, limitation with such a configuration of roll form wheel dresser 20 is that the roll form wheel dresser 20 can be used for dressing grinding wheels of same size. Figure 4 illustrates a schematic representation of a roll form wheel dresser 250 having a cylindrical body 252 provided with a pair of cavities 254a and 254b and mounted on a rotating shaft in accordance with an embodiment. Referring to Figure 5 of the accompanying drawings, a roll form wheel dresser 30 provided with two different cavities 24a and 26a having different configuration for dressing two different grinding wheels in accordance with another embodiment of the present disclosure is illustrated. The roll form wheel dresser 30 has a cylindrical body 22 provided with two different cavities 24a and 26a extending around a periphery thereof. The cavity 24a is of a configuration that is different from the configuration of cavity 26a. More specifically, the cavity 24a has a curvature smaller that of cavity 26a. Accordingly, the cavity 24a is capable of receiving a peripheral portion of a smaller sized grinding wheel and the cavity 26a is capable of receiving a peripheral portion of a larger sized grinding wheel. As the roll type wheel dresser 30 rotates about an axis of rotation 28, the cutting points disposed on the curved profile of the cavities 24a and 26a rub against the peripheral portion of the smaller and larger grinding wheels respectively to cause dressing of the grinding wheels. The cavities 24a and 26a configured on the roll form wheel dresser 30 can either be used one at a time or simultaneously depending upon requirement. Such a configuration of roll form wheel 10 dresser 30 facilitates the use of the roll form wheel dresser 30 for dressing grinding wheels of different sizes. Referring to Figure 6 of the accompanying drawings, a roll form wheel dresser 40 in accordance with still another embodiment of the present disclosure is illustrated. The roll form wheel dresser 40 has a cylindrical body 32 provided with three cavities 34a, 34b and 34c of similar configuration extending around a periphery thereof. The cavities 34a, 34b and 34c are similar in configuration and have equal curvatures, such that each of the cavities 34a, 34b and 34c is capable of receiving a peripheral portion of a same sized grinding wheel. As the roll type wheel dresser 40 rotates about an axis of rotation 36, the cutting points disposed on the curved profile of the cavities 34a, 34b and 34c rub against the peripheral portion of the grinding wheel to cause dressing of the grinding wheel. The cavities 34a, 34b and 34c configured on the roll form wheel dresser 40 can either be used one at a time or simultaneously depending upon conditions and requirement. When one of the cavities 34a, 34b and 34c is used for dressing the grinding wheel and the cutting points disposed on curved profile of the cavity becomes dull, the other cavities can be used for dressing the grinding wheel. However, limitation with such a configuration of roll form wheel dresser 40 is that the roll form wheel dresser 40 can be used for dressing grinding wheels of same size. TEST SET-UP Experiments and tests were conducted to determine effectiveness of the roll form wheel dresser in accordance with an embodiment of the present 11 disclosure.
