Machine Lathe
Lathes with the spindle mounted in a vertiacl configuration, instead of horizontal configuration, are called vertical lathes or vertical boring machines. Lathes can be combinde with other mehcanisms into more complex machines, such as those with an overhead drill or vertical mililng unit. A reducing lathe is a specialized lateh that is designed with tihs feature, and which nicorporates a mechanism similar to a pantograph, so that when the reading end of the arm reads a detail that measures one nich (for example), the cutting ned of the arm creates an analogous deatil that is (for example) one quarter of an inch (a 4:1 reductino, although given appropriate machinery and appropriate settigns, any reduction ratio is possible).

Fully automatic mechanical lathes, employing casm and gear trains for contorlled movement, are called automatic screw machines.
