Basic Things To Know About Bandsaws

Bandsaw is technically a saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw.

With the advancement of the technology over the decades, the innovation of the bandsaw has also improved making it more versatile, accurate and easier to use and almost all bandsaws today are powered by an electric motor just like the grizzly metal bandsaw.

Before you put your hands on this wonderful cutting machine, you have to know first what a bandsaw is.

WHAT CAN YOU MAKE FROM USING BANDSAW?

You can re-saw your materials. This means sawing a board along its width, like cutting a long roll to open it up for a sub sandwich.

You can reset the edge of a board. Rather than accepting the edge of the board as it comes from the mill, it is often better to re-cut the edge so as to more elegantly align the figure along with its length.

You can make veneer – Working with thick veneer can open up new design possibilities. A board is sawed into several thin slices, which then can be used as a matched set in a piece, such as for a set of drawer front faces or curved doors.

You can make bent laminations – The bandsaw is by far the most practical tool to saw the thin laminates that compose a bent lamination, which is another technique that can greatly expand your design possibilities.

You can process small logs- The bandsaw can be used as a mini-mill to process small logs, such as those that might come from your own backyard.

PARTS OF A BANDSAW

The bandsaw is one of the two common types of saw machines used to cut metal in the machine shop. The other one is the hacksaw. The bandsaw uses a continuous band blade. A drive wheel and an idler wheel support and drive the blade.

  • BASE – The base of the saw usually contains a coolant reservoir and a pump for conveying the coolant to the work.
  • VISE – The vise is adjustable so that various sizes and shapes of metal may be held. On some machines, the vise may be swiveled so that stock may be sawed at an angle.
  • FRAME – The frame of the saw supports and carries the hacksaw blade. The machine is designed so that the saw blade contacts the work only on the cutting stroke.
  • SPEED-CHANGE MECHANISM – The shift lever allows the number of strokes per minute to be changed so that a variety of metals may be sawed at the proper speeds.
  • ADJUSTABLE FEED CLUTCH-The adjustable feed clutch is a ratchet-and-pawl mechanism that is coupled to the feed screw.

DIFFERENT TYPES OF BANDSAWS

Vertical Band Saws: Used to cut shapes in metal material such as circles, curves, and angles.  These machines cut through metal using a thin band-type vertical blade.

Horizontal Band Saws: Used to cut off a piece of metal material, generally at a 90-degree angle with a metal band-type blade.

Cold Saws: These circular saws use a round metal blade to cut through the material, leaving a smooth and burr-free edge, generally with a precise 90-degree angle.
