Learn about the basics of metal lathe operations using our Smithy Granite combo lathe/mill/drill machines. You can visit us at www.smithy.com for more information or send us any questions about your project. Our trained technicians will be glad to help you with your project.

"If the project you are doing needs to be grooved, keyed, slotted, drilled, or just machined flat, the tool you need to turn to is the mill-drill machine. For milling operations, the work piece is attached to the cross slide table and fed into a revolving cutting tool. The profile of the milling cutter and the controlled movements of the machine's table govern the shape of the cut.

Here is a part made on the Smithy Mill-Drill machine. The finished shape is complex, but each individual cut that went into producing this part was very simple. That's really the key to milling. Taking one step as a time. A good machinist will look at a design and think of it as a progression of simple milling and drilling operations. This part required 22 separate cutting operations: five different mills, four drills, five different types of work holding tools, and a total of nine individual set ups on the milling table. Each set up was carefully planned in advance, so that as the cutting progressed, the machinist did not lose the ability to hold the part rigidly on the table. A successful milling operation requires a careful choice of cutting tools, work holding devices, and table movements. Lets start by looking at some of the cutting tools used on the mill and then move onto the work holding tools and the controls of the machine."

@snoopdog68 Really?  I always wondered how well constructed these machines were!
