wo types of all-wheel-drive systems: chain-driven and gear-driven. Gear-driven systems require an additional differential unit that uses approximately seven gears. Industry officials indicate that all-wheel-drive systems will contribute to the demand for gears, but are unlikely to force sub- stantial changes in gear design. 8 Vehicle gear producers, like vehicle parts manufacturers in general, are facing increased demands for improved product quality. 9 Given the critical nature of the components in which gears are used, product quality is an especially important consideration for vehicle gear producers.

Use of CBN cutting and grinding tools, made of an abrasive carbon material, allows the production of very-high-quality gears. More importantly, the use of high-quality gears results in quieter operation of heavy vehicles, many of which must comply with increasingly stringent noise reduction requirements. Furthermore, quiet gears reduce vehicle noise in truck cabs, and firms frequently use low cab noise as marketing too1. 1 Market Size Apparent consumption, as seen in the following t
