Metal Band Saw Machines
One of the earliest objects designed by the inventor to give a metal band saw machine with a 35 blade cutting with intermediate teeth having rough gullets of sufficable strength to get and contain the metal cutting from the stock through the cutting horizontal teeth, distinct in the horizontal scraping or chin scooping action, and that would…
In the early years of its conception the saw used a sliding work plate with the metal rotating on the slide. This was found to be too dangerous, so a different method was devised with the flat surface of a piece of metal placed over the work area and a heavy wooden block placed on top to act as a guide for the metal cutting. This method proved much safer and simpler than the vertical rotating work plate. The new saw was christened the “metal band saw” after George Taylor, who patented it was put into production in 1917.
One thing to notice about the old saw is that it was prone to “backsloping” when on the upswing, and in addition suffered from “chatter” as the wood on the saw “talked” with each other. All these factors combined to limit the law’s effectiveness and make it very inefficient as a power saw for general fabrication. The new design improved on this and eliminated most of the backsloping. However, the biggest problem with the old saw was that the operator needed to remain very close to the blade for maximum effectiveness. The new metal band saw continued to improve until finally it could be used with no operator assistance required.
The modern metal band saw machine is a hydraulically powered assembly line of machines. It has a large variety of cutting techniques available which includes diamond grinding, full mast grind, crosscutting, rocking cut, and even beveling. Many saws will hold an epoxy coating which protects the blade and prevents it from rusting. Some of these epoxies are clear, some are colored, and others have combination stains and colors. Each of these coatings gives the metal band saw its own particular look and can be adjusted if necessary to enhance its appearance.
The basic function of any metal band saw machine is to cut metal. The difference between this type of saw and a regular table saw is that the band saw must be pulled or pushed across the piece of stock that it is to cut. Table saws are held in place by a bed and do not require any action on the part of the operator. With a metal band saw, on the other hand, the operator must pull or push across the saw itself, which causes the blade to hit the wood or other material and deposit heat and/or debris in the cutter. If the heat and debris embed itself too deeply in the material, the blade will need to be removed and the piece of stock will need to be replaced.
Most shops need at least one metal band saw machine; if you operate only part time, you may want to consider renting a machine from a rental company to avoid having to buy your own. This will allow you to work in your shop around the clock without the worry of whether or not you’ll have something to do when you get the busy schedule of a shop. If you do decide to buy a metal band saw, you will likely find that it will be less expensive than you expected. Regardless of which style of saw you decide to buy, remember that you will probably be using the equipment most often when you operate this equipment, so purchasing the right saw will ensure that you get the most use and value out of it.
