R8 Face Mill Arbor
An R8 Face Mill Arbor is a specific type of Type F toolholder that is designed to hold a face milling cutter. The R8 designation refers to the shank size and shape, which is commonly used in Bridgeport-style milling machines. The R8 shank has a tapered shape that is designed to fit into the spindle of the milling machine, providing a secure and precise connection.
The Face Mill Arbor part of the toolholder is designed to hold the specific type of cutting tool known as a face milling cutter. These cutters are used to machine large flat surfaces and are commonly used in manufacturing and metalworking applications.
To use an R8 Face Mill Arbor, the toolholder is inserted into the spindle of the milling machine and locked into place using the drawbar. The face milling cutter is then inserted into the Face Mill Arbor and tightened using a specific type of wrench. The milling machine is then used to machine the desired surface, cutting away material with each pass.
