Introduction
When manufacturing or rebuilding components to replace worn ones in the
field, the machinists, at times, is limited to the type of operations he can
perform because the type of machines needed are not available in his
particular shop set or van. Therefore, manufacturers have developed various
attachments that can be mounted on the lathe to bridge this gap.
These
attachments, when mounted on the basic engine lathe, will allow the
machinists to perform milling, grinding, drilling, and slotting operations.
During this task, we will discuss the uses, repair, and adjustments on some
of the lathe attachments.
