Features

Operations of internal and external machining for turning, boring and facing both ends of medium or small size parts can be finished in one setting.
Save time on part loading, unloading and tool setting between two operations and increase productivities.
Second operation can be processed right after bar material being cut off.
Finished parts will be collected with programmable parts catcher (optional) automatically.
This lathe is one of the supreme efficient productive machines.
