Saw Cutting: A Machining Process

Saw Cutting

Saw cutting is a fabrication or machining process that refers to the segmentation a workpiece by using a saw blade to cut the material. The three most basic types of saws used for cutting in the machine shop environment include the continuous band saw, the cut-off saw and the cold saw. These machines are designed to complete the cut in a short time and at a desired level of quality.

The band saw is a machine that cuts the workpiece or part with a hardened metal blade which sports serrated teeth. As the blade moves across the workpiece, slight downward pressure is applied. Each tooth that passes removes a small amount of material, and since this saw utilizes a looped blade, it provides a continuous cutting action. In an automatic band saw the workpiece or length of material is automatically fed forward to ensure multiple cuts are made to a preset length. The material is held in a hydraulic vise which works in conjunction with the material feed and cut action. Proper setup and monitoring will ensure saw cut parts are produced with measurable, repeatable results.

The cut-off saw, or chop saw utilizes a very thin abrasive wheel to saw cut the material. Very similar in configuration the cold saw utilizes spinning circular steel blades similar to those used in wood saws. Both the abrasive wheels and the circular steel blades of cut-offs and cold saws cut quickly and give an excellent saw cut finish.
