Definitions
- the present invention relates generally to rough-cut and polishing wheels of the type used for edging of an optical edge. More specifically, the present invention relates to rough-cut and polishing wheels that reduce the necessary manual removal of swarf from the lens after rough cutting, fine grinding, finishing, polishing, and/or beveling of an optical lens, so as to improve lens edge quality and/or geometry.
- Optical lenses are typically made of various materials, such as polycarbonates and high index plastics, as well as those materials currently marketed under the trade names CR39® and TRIVEXTM (both readily commercially available from PPG Industries, Pittsburgh, Pa.).
- an edging machine which includes a rough-cut wheel for cutting out the shape, fine grinding and finishing wheels for further shaping of the lens, and polishing and beveling wheels for providing the final contour.
- the grinding operation creates abrasive swarf material that requires removal in order for proper use of any type of abrasive device.
- the wheels have buildup of swarf during the operation, which imparts itself onto the lens or, alternatively, the grinding process does not remove the excess material. This creates the need to manually remove the swarf from the lens. Any swarf that is not readily removed during the grinding of the edging operation, interferes with the operation and, at the very least, slows it down and may add to several hand finishing steps necessary at the end, or an improper lens configuration.
- TRIVEXTM has been a particularly troublesome material to shape and finish.
- TRIVEXTM does appear to be a new and preferred lens making material.
- conventional forming wheels have resulted in much scrap and have otherwise been proved to be unsuitable for use with TRIVEXTM materials for lenses. Therefore, it has become a goal to provide an abrasive wheel capable of processing TRIVEXTM lenses that can also be used for all other type of lens materials.
- a rough-cutting wheel for rough cutting of an optical lens blank.
- the wheel comprises a hub portion that is adapted for attachment to a rotary power source.
- the wheel includes an outer circumferential cutting surface having a width.
- the outer circumferential cutting surface includes sufficient abrasive grit attached thereto to accomplish rough cutting of any conventional optical lens blank.
- the wheel includes a radially extending planar side portion, and in a preferred embodiment, has at least one swarf clearing groove extending at an angle to said side portion across the circumferential groove and opening into the planar side portion, which allows removal of swarf out through the planar side portion.
- each groove is preferably configured so as to be angled with respect to any adjacent groove, e.g., either angled towards or away from any adjacent groove.
- the grooves may be present in multiple configurations, such as pairs and the like.
- a polishing wheel for edge finishing of an optical lens blank.
- the wheel comprises a hub portion that is adapted for attachment to a rotary power source.
- the wheel includes an outer circumferential cutting surface having a width.
- the outer circumferential cutting surface includes sufficient abrasive grit attached thereto for polishing of an optical lens blank.

Description
- This application claims the benefit of U.S. Provisional Application No. 60/505,564, filed Sep. 24, 2003.
- The present invention relates generally to rough-cut and polishing wheels of the type used for edging of an optical edge. More specifically, the present invention relates to rough-cut and polishing wheels that reduce the necessary manual removal of swarf from the lens after rough cutting, fine grinding, finishing, polishing, and/or beveling of an optical lens, so as to improve lens edge quality and/or geometry.
- Optical lenses are typically made of various materials, such as polycarbonates and high index plastics, as well as those materials currently marketed under the trade names CR39® and TRIVEX™ (both readily commercially available from PPG Industries, Pittsburgh, Pa.).
- In order to finish and make these lenses ready for fitting into a lens frame, it is necessary to edge the outer periphery of the lens, to give it the proper cross-section to fit in an eyeglass lens frame. Typically, this is done by an edging machine, which includes a rough-cut wheel for cutting out the shape, fine grinding and finishing wheels for further shaping of the lens, and polishing and beveling wheels for providing the final contour.
- Depending on the lens material, the grinding operation creates abrasive swarf material that requires removal in order for proper use of any type of abrasive device. Typically, the wheels have buildup of swarf during the operation, which imparts itself onto the lens or, alternatively, the grinding process does not remove the excess material. This creates the need to manually remove the swarf from the lens. Any swarf that is not readily removed during the grinding of the edging operation, interferes with the operation and, at the very least, slows it down and may add to several hand finishing steps necessary at the end, or an improper lens configuration.
- TRIVEX™ has been a particularly troublesome material to shape and finish. However, TRIVEX™ does appear to be a new and preferred lens making material. Unfortunately, conventional forming wheels have resulted in much scrap and have otherwise been proved to be unsuitable for use with TRIVEX™ materials for lenses. Therefore, it has become a goal to provide an abrasive wheel capable of processing TRIVEX™ lenses that can also be used for all other type of lens materials.
- In the optical industry today, the “one-hour” optical labs and the like have made it necessary for increased efficiencies in the processing of optical lens production. Therefore, it is desired to eliminate swarf removal on the optical lens by hand, regardless of the material used, which is labor intensive and time consuming.
- Therefore, it is a goal in the art to provide rough-cut, fine grinding, finishing, polishing and/or beveling wheels, and methods for using the same, that eliminate the need for manual swarf removal.
- In accordance with one embodiment of the present invention, there is provided a rough-cutting wheel for rough cutting of an optical lens blank. The wheel comprises a hub portion that is adapted for attachment to a rotary power source. The wheel includes an outer circumferential cutting surface having a width. The outer circumferential cutting surface includes sufficient abrasive grit attached thereto to accomplish rough cutting of any conventional optical lens blank. The wheel includes a radially extending planar side portion, and in a preferred embodiment, has at least one swarf clearing groove extending at an angle to said side portion across the circumferential groove and opening into the planar side portion, which allows removal of swarf out through the planar side portion. In another preferred embodiment, each groove is preferably configured so as to be angled with respect to any adjacent groove, e.g., either angled towards or away from any adjacent groove. In a further preferred embodiment, the grooves may be present in multiple configurations, such as pairs and the like.
- In accordance with another embodiment of the present invention, there is provided a polishing wheel for edge finishing of an optical lens blank. The wheel comprises a hub portion that is adapted for attachment to a rotary power source. The wheel includes an outer circumferential cutting surface having a width. The outer circumferential cutting surface includes sufficient abrasive grit attached thereto for polishing of an optical lens blank. The wheel includes a radially extending planar side portion, and in a preferred embodiment, has at least one swarf clearing groove extending at an angle to said side portion across the circumferential groove and opening into the planar side portion, which allows removal of swarf out through the planar side portion.

It should be appreciated that grit rating outside of these ranges, i.e., less than 80 and/or greater than 600, may be used as well in the practice of the present invention, should circumstances require (e.g., material specific requirements). - It should also be appreciated that other configurations may be employed with the grooves of the present invention. By way of a non-limiting example, crisscross or “X-shaped” patterns can be used as well in the practice of the present invention.
- The use of the described wheels, whether for rough cutting, fine grinding, finishing, polishing, beveling, or the like, is fairly straightforward. The wheel is preferably mounted to a rotary motion machine, which preferably allows the wheel to selectively rotate about an axis, wherein at least a portion of the cutting face is accessible (e.g., by a work piece such as an optical lens blank). The wheel is then rotated while an optical lens blank is brought into contact with the rotating wheel for a sufficient period of time. As swarf material is generated by the frictional engagement, the swarf material is preferably carried away from the surface of the optical lens blank and/or the wheel by the swarf-clearing grooves of the present invention. It will be appreciated that the choice of wheel will be dependent, in part, on the particular action to be carried out, e.g., rough cutting, fine grinding, finishing, polishing, beveling, or the like. Thus, in the production of a particular finished optical lens, it may be necessary to employ multiple types of wheels, e.g., one for rough cutting, one for fine grinding, one for finishing, one for polishing, one for beveling, and so forth, to perform the required cutting, grinding, finishing, polishing, or beveling functions.
- Testing of the wheels of the present invention have shown an increase in the ease of swarf material removal during the grinding process, a reduction in the number of burrs on the edge surfaces of the optical lens blanks, a reduction in grinding noise levels, and a reduction in odor levels due to the grinding process. Additionally, wheels of the present invention cut cool enough to allow grinding of TRIVEX™ and polycarbonate lens materials substantially without melting. The present invention allows cooler cutting and improved edge finishing qualities whether in rough cutting, finish cutting or polishing operations.
- Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited, since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
