Defination

                    A bandsaw is a power tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. It's also a useful machine in a woodworking shop. The band usually rides on two wheels rotating in the same plane, although some bandsaws may have three or four wheels. Bandsawing produces uniform cutting action as a result of an evenly distributed tooth load.Bandsaws are used for woodworking, metalworking, or for cutting a variety of other materials. They are particularly useful for cutting irregular or curved shapes, but can make straight cuts. The minimum radius of a curve that can be cut on a particular saw is determined by the width of the band and its kerf.

 Introduction

             A sawing machine is a machine tool designed to cut off bar stock, tubing, pipe, or any metal stock within its capacity, or to cut sheet stock to desired contours. The sawing machine functions by bringing a saw blade containing cutting teeth in contact with the workpiece to be cut, and drawing the cutting teeth through the workpiece. The sawing machine is much faster and easier than hand sawing, and is used principally to produce an accurate square or mitered cut on rectangular or cylindrical material. One of the two common types of sawing machines used for metal cutting in the machine shop is the bandsaw machine. The bandsaw machine cuts by drawing a continuous metal band, called a bandsaw blade, across the workpiece. 

                    The bandsaw blade is supported and driven by a drive wheel and an idler wheel.This subcourse describes bandsaw operations and maintenance. This lesson introduces three common models of bandsaw machines and describes their use.

   Uses of Bandsaw Machines

                     The bandsaw machine is used for external and internal sawing. With the use of attachments, the bandsaw machine can also serve a variety of other functions. Band files and polishing bands can be used in place of the  bandsaw blade for filing and polishing operations. A disk cutting attachment permits the cutting of true circles. An angular blade guide attachment is furnished with most bandsaw machines. This attachment twists the bandsaw blade so that large or long workpieces that would not normally clear the bandsaw machine column can be cut. A miter guide attachment can be used to guide the workpiece at any convenient angle.

       Meat cutting

                      Saws for cutting meat are typically of all stainless steel construction with easy to clean                 features. The blades either have fine teeth with heat treated tips, or have plain or scalloped knife           edges.

        Metal cutting

19th century wood bandsaw

                      Bandsaws for cutting metal are available in                   vertical and horizontal designs. Typical band speeds range         from 40 feet (12 meters) per minute to 5,000 feet (1,500             meters) per minute, however specialized bandsaws are               built for friction cutting of hard metals and run band                     speeds to 15,000 feet per minute. Metal-cutting bandsaws         are usually equipped with brushes or brushwheels to                   prevent chips from becoming stuck in between the blade's         teeth. Systems which cool the blade are also common                 equipment on metal-cutting bandsaws. The coolant                     washes away chips and keeps the blade cool and                       lubricated.

     Timber cutting

                    Timber mills use very large bandsaws for ripping lumber; they are preferred over circular             saws for ripping because they can accommodate large-diameter timber and because of their                   smaller kerf (cut size), resulting in less waste.

      Head saws

                  Head saws are large bandsaws that make the initial cuts in a log. They generally have a 2 to        3 in (51 to 76 mm) tooth space on the cutting edge and sliver teeth on the back. Sliver teeth are              non-cutting teeth designed to wipe slivers out of the way when the blade needs to back out of a cut.

        Resaws

                  A resaw is a large bandsaw optimized for cutting timber along the grain to reduce larger                 sections into smaller sections or veneers. Resawing veneers requires a wide blade - commonly 2           to 3 in (51 to 76 mm) - with a small kerf to minimize waste. Resaw blades of up to 1 in (25 mm) may         be fitted to a standard bandsaw.

        Double cut saws

               Double cut saws have cutting teeth on both sides. They are generally very large, similar in               size to a head saw.
