Pöytäsirkkeli

Pöytäsirkkeli, also known as a table saw, is a woodworking tool consisting of a circular saw blade mounted on an arbor, driven by an electric motor. The blade protrudes through the surface of a table, which provides support for the material being cut. Table saws are used for a variety of cuts, including rip cuts (cutting along the grain of the wood) and crosscuts (cutting across the grain). They are a common and essential tool in both professional woodworking shops and DIY home workshops.

The blade's depth of cut can be adjusted by raising or lowering it relative to the table surface. Most table saws come equipped with a miter gauge, which slides in a groove on the table and allows for angled cuts. Many also feature a rip fence, a guide parallel to the blade, used for making consistent width rip cuts. Safety features are crucial for table saws, and they typically include a blade guard, riving knife or splitter to prevent kickback, and a power switch that can be easily accessed in an emergency.

Table saws are available in various sizes and power levels, from small benchtop models suitable for hobbyists to large industrial cabinet saws designed for heavy-duty professional use. The choice of blade type also influences the cut quality and type of material that can be processed. For instance, fine-toothed blades are better for smooth crosscuts, while coarser blades are more efficient for rip cuts. Proper maintenance, including blade cleaning and sharpening, is essential for optimal performance and safety.
