PRIORITY CLAIM AND CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application No. 61/503,463 filed on Jun. 30, 2011, and entitled “A Method of Polishing a Workpiece with an Abrasive Segment Comprising Silicon Carbide Abrasive Aggregates,” and naming Guan Wang et al. as inventors, which is incorporated by reference herein in its entirety. This application also claims priority to U.S. Provisional Application No. 61/529,059 filed on Aug. 30, 2011, and entitled “A Method of Polishing a Workpiece with an Abrasive Segment Comprising Silicon Carbide Abrasive Aggregates,” and naming Guan Wang et al. as inventors, which is also incorporated by reference herein in its entirety.

BACKGROUND

1. Field of the Disclosure

This disclosure, in general, relates to polishing a workpiece. More particularly, the disclosure relates to polishing a workpiece with an abrasive segment that includes abrasive aggregates having silicon carbide particles.

2. Description of the Related Art

Abrasive articles, such as coated abrasives and bonded abrasives, are used in various industries to machine workpieces, such as by, grinding, or polishing. Machining utilizing abrasive articles spans a wide industrial scope from optics industries, automotive paint repair industries, to metal fabrication industries. In each of these examples, manufacturing facilities use abrasives to remove bulk material or affect surface characteristics of products.

For example, abrasive articles, such as abrasive segments may be used when polishing or finishing certain various types of workpieces, including, for example, metal, wood, or stone. In particular instances, abrasive segments containing abrasive grit contained within a binder material may be used to effectively finish stone. However, the industry continues to demand improvements in abrasive technologies.

SUMMARY

In one aspect, the disclosure is directed to a method of polishing a workpiece. The method can include placing a workpiece on a support structure. In an embodiment, the method can also include contacting the workpiece with an abrasive segment. The abrasive segment can include a plurality of abrasive aggregates that include silicon carbide particles bound together in a binder material. Additionally, the method can include moving the abrasive segment and the workpiece relative to each other.

The above and other features described herein including various details of construction and combinations of parts, and other advantages, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims. It will be understood that the particular method and article embody certain features that are shown by way of illustration and not as limitations and that the principles and features described herein may be employed in various and numerous embodiments.
