of milling machines, this document will focus only on the vertical milling machine. A milling machine removes metal by rotating a multitoothed cutter that is fed into the moving workpiece. The spindle can be fed up and down with a quill handle on the head. The goal of this SOP and the accompanying "training" is not to make you a mill ...

The most common way to fasten the arbor in the milling machine spindle is to use a draw bar. The bar threads into the taper shank of the arbor to draw the taper into the spindle and hold it in place. Arbors secured in this manner are removed by backing out the draw bar and tapping the end of the bar to loosen the taper.

Step 1: The Design and CAD Model. It all started with a proper design, in my case a few sketches to get a good feeling for the dimensions and shape. Quickly after the sketching phase came the CAD model. I created my model in SolidWorks. If you plan to design your own machine I recommend a parametric CADmodeling tool.

1. 123 Block. Making these may not be as easy as 123, but these blocks sure count for many uses in a machine shop! A 123 block is a piece of steel, ground to a square 1 by 2 by 3 inches and usually drilled with a pattern of threaded holes. It's ideal for setting up machines, inspecting parts, measuring, or simply holding down some paper.

Ghost Gunner is built from rigid aluminum unibodies, placed inside a plasmacut A36 steel enclosure. The machine part count is greatly reduced compared to traditional CNC machines, which both increases rigidity and decreases cost. GG3 employs a horizontal milling format, a 9,000 rpm ER11 collet unibody machined spindle and has a machinable ...

Parts support will be a little better than average for a low cost import machine, but if the mill is more than 3 years old or so parts support will be spotty. So I'd only buy it if its in very good working condition. Search the web for info on how to check out BP type machines, there's lots of discussion of this on the various Bridgeport forums.
