Since the advent of the band saw machine, it has been used and improved for several generations. Today it has become one of the most extensive machine tools on the market.

Coating of the sawing bands

Saw blades, or saw bands, are critical to the cutting result. Since the adoption of bi-metal technology in the 1960s, saw blades have begun to use carbide-tipped blades.

Why coating matters?

Before the invention of the bi-metal blades, the cutting efficiency of the sawing machine was stagnant and could not be improved. The band saw blade was once completely made of high carbon steel because it was flexible enough to withstand the winding path around the drive wheel of the band saw machine and the stress generated by the saw blade guide. Bi-metal and carbide-tipped band saws have greatly changed the sawing industry. Since then, the tooth and geometric shape tooth designs on the band saw machine have been widely used.

Prolonged lifespan and wider application

With a good coating onto the surface of the sawing blades, the blade can be used for sawing tasks and maintain good performance in the process. The metal has an enhanced physical essence after surface treatment, which can ensure stable sawing quality and accuracy. Coating materials vary, coating material and treatment method are serous lessons for blade manufacturers, and the results can greatly affect the life of the saw blade. The use of well-coated saw blades can expand the application field and further help saw blade manufacturers gain a larger market share in the industry. At the same time, it brings better business profits and capital investment for saw blade manufacturers.

Advantages

Therefore, the main advantages of a band saw machine compared to circular saws include uniform cutting motion due to uniformly distributed tooth loads, and the ability to cut irregular or curved shapes like a jig saw. The minimum radius of the cutting curve is determined by the width of the saw band and the curve. These advantages make the band saws in the metal processing industry unique and irreplaceable.

Differences between sawing methods

Circular saw machines use circular tools to perform sawing procedures instead of using saw bands, which results in different processing characteristics of circular saw machines. Generally, a circular saw is a power saw that uses a toothed or abrasive disc set or saw blade to cut material through a rotational movement around a mandrel. In similar applications, hole saws and circular saws also use rotary motion, but are different from circular saws. Circular saws can also be used on the blade itself. The circular saw was invented in the late 18th century in response to the growth of the agricultural industry. By the middle of the 19th century, circular sawing machines were widely used in sawmills in the United States.

Circular saws are machining tools used to cut many kinds of materials, such as wood, masonry, plastic or metal. The circular saw machine can be hand-held or mounted on the machine. Versatility is one of the main characteristics of this type of saw. The term "circular saw" refers specifically to hand-held and bench saws. At the same time, chop saws are also a conventional type of circular saws in the woodworking industry.

New trends

Programmed sawing is a must for modern sawing procedures. With the application of agile and intelligent manufacturing in machinery in various fields, whether it is a band saw or a circular saw, the ability to perform multi-task sawing has become a decisive factor for competition among saw machine manufacturers.
