Vertical Machining Centers C-Frame Style

C-frame style Here are the components making up a C frame style machining center…

C-frame style Bed

C-frame style Bed Y axis Ways

C-frame style Column

C-frame style Column Z axis ways

C-frame style Headstock

C-frame style Headstock Spindle

C-frame style This machine is called a “C frame style” because the headstock, column, and bed for a letter “C”.

C-frame style This machine is called a vertical machining center because the spindle is oriented in a vertical fashion.

C-frame style Saddle

C-frame style Saddle X axis ways

C-frame style Table

C-frame style Splash Guard

C-frame style Automatic tool changer

This style of machine may have certain accessories…

C-frame style Indexer An indexer is used to quickly rotate the workpiece to expose a surface to the spindle
