| Abstract | was on the fringes of machining technology. Manufacturing engineers used it only when they had to, usually because a metal was too difficult to cut or finish any other way. The picture is changing today with about 25% of all industrial grinding in Japan done with CBN, 15% in Europe, and 10% in the US. Although CBN use in the US is statistically low, interest is quite high. Predictions are that its use will expand dramatically for three reasons: conversion from other abrasives, chiefly aluminum oxide; introduction of CBN compatible grinders; and new applications as harder, more complex work materials are introduced. According to data from GE Superabrasives (Worthington OH), global sales of CBN wheels was $145 million in 1988, reaching $300 million last year. The company estimates use can grow another 4.5 times to reach $1.6 billion. In the US, CBN wheel sales for 1992 were an estimated $63 million, only a 13% penetration of the potential $480 million market. Currently, the automotive industry is the largest user of CBN wheels with 30% of the market, says GE. Tool production (both production and resharpening) is the second largest market with about 20% of sales. Bearing manufacturing is a growing application now representing 12% of total use. Aerospace and gear manufacturing follow with 9% and 8%, respectively. As to grinding techniques, CBN has made its greatest inroads with ID grinding because wheels are smaller and, therefore, less costly. |
