A milling machine is a versatile machine tool that can do even the most detailed engravings. From simple jewelry designs to three-dimensional images, these patterns can be done with the use of an engraving tool that is attached to the machine.
An engraving attachment is typically an air spindle that is mounted by a clamp or a screw to the main axis of the mill. An air spindle can be powered either by a router or an air compressor. The router has a maximum speed of 23,000 revolutions per minute, while the air compressor can power the spindle to up to 40,000 RPM. It is the speed of the spindle that determines the machining efficiency of the attachment. The higher the RPM, the better it is for more detailed jobs.
This special-purpose attachment comes separately from the machine and is specifically designed only for fine machining. For more information about air spindle and other milling machine accessories, visit CNCMasters.com or call 1-877-262-8895.
