Rotary Bushings Keep U.S. Auto Makers on the Line
Rotary bushings are commonly deployed in transfer line tooling applications such as automotive engine block cam, and crank boring. A step beyond the more common, and better known common drill bushing, rotary bushings not only facilitate accurate cutting they also eliminate heat, wear and chatter. Their use in production can boost CPK value as well, a calculation that gauges the extent to which a process has met the quality specification limits established by customers.
Although rotary bushings are a small but vital component of high-volume manufacturing, they can also be troublesome. This is due to the design limitations of most boring machines. Past practice involved mounting individual detail parts directly into the machine housing. The line boring bar moves through the bushings
