Milling
Milling is the most versatile machining operation, able to perform all the functions below and more. If you don’t know which ones you need don’t worry! We’ll figure that all out for you. Mills use a spinning cutter in a spindle to cut away material from the part which is held in a vise below. The table and spindle can be moved very accurately to hold tight tolerances on the part, and the cutters can cut a wide range of materials. Additionally, a rotary table can be added to further expand the capabilities of the mill with a rotational axis.
Materials: Metals (Steel, Brass, Stainless, Titanium), Plastics
Uses: Orthogonal shapes mostly, but flexible
Part Complexity: Simple shapes, highest accuracy
Cost: $60 per hour
Maximum Part Size: 11.8 x 5.1 x 10.6 in (300 x 130 x 270 mm)

Milling Processes
Decking
Decking gives a very flat surface to a part, generally with superior surface finish.
Pocketing
Pocketing rectangular shapes (or combinations of rectangular shapes) is a common and straightforward procedure.
Shouldering/Slotting
Cutting shoulders or slots is quite common and may take any number of orthogonal shapes.
Profiling - Rectangular
Profiling defines the perimeter of the part, and can be easily done for any number of orthogonal edges.
Bolt Hole/Threads Patterns
Holes can be drilled at any X-Y coordinates to produce patterns to match any mating part. Additionally, holes can be blind or through tapped for screw threads.
Milling Processes - Rotary Table
Arc Pockets/Shouldering
Cutting perfect circles and arcs for pockets, shoulders, and profiling is now possible.
Circular Hole Patterns
Rotary Symmetrical Features
Repeat any other features at angular intervals (30°, 60°, 17.2°). Perfect for making hexagons, dials, and knobs.
