This Video Shows the Viewer How to Select the Best Cutting Tool For Milling Operations - Basic Tutorial - SMITHY GRANITE 3-in-1

(Sample quote from video:)

"The most widely used cutting tools on a vertical milling machine are end mills. These mills have cutting edges on the sides and bottom. They are primarily used to make narrow facing cuts or to mill slots and pockets. You can also use the cutting edges on the periphery of the tool to do light planing cuts."

The machine that Dave is using for demonstration purposes is the Granite MAX 1324. This lathe-mill-drill combo machine sets the standard for premium quality bench top machine tools.

Putting a combination machine tool in your shop allows you to have the capabilities of a small machine shop without sacrificing too much floor space.

The Granite 3-in-1 “big machine” features and premium quality is comparable to other larger, more expensive machine tools. PLUS, you'll have three machines in one.

Nearly 30,000 Smithy machines are working hard every day in shops across North America. This fact let's you know that Smithy machines do set the standard for quality.

As Close As You’ll Get to American Made

1) US Developed and Designed: The Granite Machine was designed by our engineers in Ann Arbor, Michigan based on machine user requests.

2) Precision is far higher than other 3-in-1 knock-offs: All components are machined to tighter specs, bearings are much higher grade, and the basic design is initially higher precision.

3) Higher Quality Production: Smithy employees oversee the production and quality control process at our sister factory of more than 25 years. No other seller can make that claim.

4) Superior Features: No machine out there can match the speed and accuracy with which you can accomplish your machining tasks on a Granite machine. Other 3-in-1 combo tools on the market are NOT EVEN in the same category for quality as the Smithy line of machine tools.

"Today, end mills are made in a wide range of sizes and styles. And, like lathe cutting tools, they are also made from many different types of materials. Small end mills are usually made from a solid piece of cutting material, in this case, high speed steel. For general machining, these tools are ground with two, three, or four cutting edges.

For high-precision cuts with a fine finish, tools with six or more cutting edges are available. Other special purpose end mills, like ball end mills, dovetail cutters, corner-rounding cutters, t-slot cutters and keyway cutters are available for cutting specific shapes. Here we are looking at a face milling cutter. This tool has a two-inch cutting diameter and uses three replaceable carbide inserts, similar to the ones we used on the lather. Fly cutters use a single point cutting tool to plane flat surfaces. The tool bit is mounted in a groove on the cutter's head. As the spindle turns, the point of the tool cuts a circular pattern on the work piece, producing a flat surface. Fly cutters are able to take fairly wide, light cuts, which can produce an excellent finish.

The tool that is most often used to cut a narrow slot is a slitting saw. These saws come in a number of widths, diameters, and tooth sizes. The teeth on these tools are very fine, compared to other milling cutters, so the cutting speed should be slow.

Hole milling operations are another important job that can be done on the Smithy. The most commonly used tool for this work is of course a drill, but after the hole is drilled, other tools can be used to modify or finish the hole. A good example would be countersinks and counter bores.
