Circular Sawing Machines

Regarding the sawing of the work pieces, circular sawing is not like band sawing machines in many aspects. A circular sawing machine will exploit circular tools to conduct sawing procedure rather than sawing band blades to achieve the cutting mechanism, which leads to other machining features that is different from band sawing mechanism.

Conventionally, a circular saw is a powered saw that uses a toothed or abrasive disc set or blade to cut different materials by a rotary motion spinning around an arbor. To be precise, circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle period of the 19th century due to the growth of industry over agricultural sectors in the US at that time. Regarding the applications, a circular saw is a machining tool for cutting many materials such as wood, masonry, plastic, or metal. Circular saw may be hand-held or mounted onto a machine, as both models work well.

Types of Circular Sawing Machines

Applied sectors

While circular sawing is a widely used machining method, there are different references in the sectors. For instance, in the sector of woodworking, the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other conventional forms of circular saws. Besides, the terms "Skilsaw" and "Stihl saw" have also become generic trademarks for conventional hand-held circular saws in the market of sawing machines.

Blades

Circular saw blades are specifically made for each particular material they are intended to cut due to the material-specific demands. And in the sector of cutting wood there are specifically designed objects for making rip-cuts, cross-cuts, or a combination of both in order to best achieve the targeted cutting tasks.

How does it work?

Driven power is the core of the circular sawing. Normally circular saws are commonly powered by electricity, but may be powered by a gasoline engine or a hydraulic motor which allows it to be fastened to heavy equipment, because it can eliminate the need for a separate energy source.

The driven process may be gear-driven or belt driven, but mostly are with transmission components so that there are speeds options for onsite operators to choose the optimum working modes based on the conditions. Nowadays with the servo motor has been widely adopted in machinery, newly developed circular controlled by computer are with new power motors in order to save energy consumption and to offer smooth and stable operation.

Firmly clamped: Do not move!

During the sawing procedure, the targeted material to be cut, that is, the work piece, is securely clamped or held in a hydraulic vise, and the saw blade or other cutting tools are advanced slowly across it. In some variants such as the table saw, the saw is fixed and the material to be cut is slowly moved into the sawing blade.

As each tooth in the blade strikes the materials, it makes a small chip and the chip issue is also another modern machining problem to be dealt with by conveyors. During the processing, the teeth will guide the chip out of the work piece (the object to be cut by sawing blade), preventing it from binding the blade.

Band saw and circular saw are different

There are two kinds of sawing machines in the industrial market: band sawing machine and circular sawing machine. This kind of classification makes perfect sense because the two are different. As mentioned beforehand, circular sawing machine utilizes spinning circular tools to process sawing procedure rather than sawing bands to achieve the cutting mechanism, which leads to other machining features that is different from band sawing method. On the other hand, a band saw is also called as bandsaw, which is a power-driven sawing machine with a long and sharp blades consisting of a continuous band of toothed metal stretched.

Advantages

The primary advantages of band saw machines include uniform cutting movement as a result of an evenly distributed tooth loads, and the capability to cut irregular or curved shapes like a jigsaw. Accordingly, with these two kinds of sawing methodology, there evolve two kinds of sawing machines that people use nowadays. The conventional one evolves into band sawing machine while the abrasive counterparts evolve into circular sawing method and the corresponding facility, or formally stated as circular sawing machine model.

Comparison: Circular vs. Bandsaw

After the invention of circular sawing and the corresponding application exist, it is a general question that is repeatedly asked: Shall onsite operators choose a band saw or a circular saw instead? Practically speaking, it shall be based on what and how a work piece is going to be cut and to be used. It is obvious that making a wrong choice would cause compromise of productivity and the plants’ long term development would face severe difficulties.

Now, band sawing machines are widely applied in a wide variety of applications. Regarding the major applications, a band sawing machine is used particularly in metalworking, woodworking, and lumbering sectors, but can also be used to cut a variety of other materials. If one compared band sawing with circular sawing, the primary advantages of band saw machines include uniform cutting movement as a result of an evenly distributed tooth loads, and the capability to cut irregular or curved shapes in a massive quantitative amount of work pieces.
