Rapid Curing of Resin Bonded Grinding Wheels

摘要

A system and process for rapid and uniform curing of grinding wheels (2) to obtain grinding wheels (2) with better durability, at 180-220° C. deploying microwave energy at 800-5000 MHz in which closely fitting green wheel sample holders (1) are made of carbon bearing microwave susceptor materials such as graphite, silicon carbide with tiny holes on the surface. These sample holders (1) help in maintaining the shape and geometry of the final wheels (2) after curing and reduce energy consumption. The performance of the grinding wheels (2) cured by this process is better than those cured by presently used process employing steel plate sample holders of the present state-of-art.

主权项

1. A system for rapid and uniform curing of grinding wheels for obtaining grinding wheels, comprising
a. a plurality of green samples of grinding wheels, b. a microwave cavity, c. a plurality of sample holders made from microwave susceptible materials, each sample holder having a substantially identical profile as a corresponding one of the green samples of grinding wheels, d. a temperature sensor, and e. a temperature controller for controlling the temperature of the sample within the microwave cavity.
