CNC Basics : 1

Images 1.2: An industrial spindle (left) or woodworking router (right) is used to hold the router bit on a CNC machine. Spindles run quieter than routers and last longer, but cost several times more. Spindles are available as either fan-cooled or water-cooled. Water-cooled spindles are often less expensive, but water-cooled spindles require a reservoir and pump to circulate the water.

Image 1.3: A spoilboard usually covers the machine bed to protect it during cutting, since many CNC operations involve cutting slightly through the project material. The spoilboard is considered a consumable and replaceable part of the machine.
