Electric drive for high-speed surface-broaching machine

摘要

The requirements of the electric drive for this high-speed surface-broaching machine are analyzed in detail. This machine is capable of developing a peak of 600 horsepower and can remove rapidly a large amount of metal from a securely held rough forging or casting to an accurate surface finish in one pass of successive broaching tools. It can produce over 150 pieces per hour at cutting speeds exceeding 200 feet per minute.
