Why buy a horizontal boring machine instead of another machine tool?

Horizontal boring machines have the spindle mounted horizontally with the workpiece stationary and the tool turning. This allows for boring of much larger work pieces than a vertical boring machine tool.  Traditional horizontal machining centers aren’t built for the larger pieces. The spindle advances out from its headstock on horizontal boring machines which allows the end user to reach into small cavities. Horizontal boring machines are built to support the boring of very large parts for a wide range of industries.
