Lathe Accessories
Brass Round Stock (铜质圆料) Brass is a nice material to work with, though somewhat expensive compared with aluminum or steel. It can add a nice touch of contrasting color to a project that will be displayed. The alloy most often used for home shop work is 360.
Poor quality drills are easy to find, but they are truly a waste of money. That‘s not to say that you need to buy top quality industrial drills. It’s not always easy to tell a good drill bit from a poor one just by looking and, of course, its even harder if all you have is a picture on a web site or in a catalog. Generally, though, the lowest priced drill sets are the ones to stay away from.

Drilling
Drilling is performed with a rotating tool called a drill. Most drilling in metal is done with a twist drill. The machine used for drilling is called a drill press. Operations, such as reaming and tapping, are also classified as drilling. Reaming consists of removing a small amount of metal from a hole already drilled. Tapping is the process of cutting a thread inside a hole so that a cap screw or bolt may be threaded into it.

Turning and Boring
The lathe is commonly called the father of the entire machine tool family. For turning operations, the lathe uses a single-point cutting tool, which removes metal as it travels past the revolving workpiece. Turning operations are required to make many different cylindrical shapes, such as axes, gear blanks, pulleys, and threaded shafts. Boring operations are performed to enlarge, finish, and accurately locate holes.

Grinding Grinding makes use of abrasive particles to do the cutting. Grinding operations may be classified as precision or nonprecision, depending on the purpose. Precision grinding is concerned with grinding to close tolerances and very smooth finish. Nonprecision grinding involves the removal of metal where accuracy is not important.
