Tokarka jest "designed for bar and chuck work".

Ogólny sens jest mniej więcej znany:

To chuck a tool or workpiece is to hold it with a chuck, in which case it has been chucked. Lathe work whose workholding involves chucking individual slugs or blanks is often called chucking work, in contrast to bar work or bar feed work. In bar work the bar protrudes from the chuck, is worked upon, then cut off by a lathe tool (parted off) rather than being sawn off. Automatic lathes that specialize in chucking work are often called chuckers. (Wiki)
