Joint spacing normally ranges between 10 to 18 feet depending on the amount of reinforcement the slab has. If you are using high shrinkage concrete, you might want to decrease the cut spacing. Here are other factors to will help you determine where to saw cut:
Featuring a carbide grit cutting edge by laser melting technology, the wheel provides a durable and safe work performance on multi materials. The thin body design and expansion slot ensure a unique cutting speed and avoid blade deformation. It is suitable for cutting into wood, wood with nails, plastics, drywall and copper pipes.
Respect to Tensioning, Rotating, Cutting, and Expansion Slots Charles B. Ponton (Abstract) Little research has been done to determine the stress states developed in an along the center of the solid disc, the thickness used in the model is half the thickness of actual annulus represented. This annulus is rotating at 222.222
Featuring a carbide grit cutting edge produced with laser melting technology, the wheel provides a durable and safe performance on a wide range of materials. Its slim body design with expansion slot ensures exceptionally high cutting speeds and prevents blade deformation. X-LOCK Carbide Multi Wheel cutting discs also fit standard angle grinders.
The fit between the root and slot provides room for thermal expansion while still retaining the blade against centrifugal force as the disc rotates at high speed (10,000 rpm is typical). Cutting the fir tree pattern on both the disc and the blade root has been a challenge for jet engine manufacturers.
Expansion Slots. Slots cut radially into the blade body which control the expansion of the blade due to heat and centrifugal forces. Expansion Slots: (Carbide tipped circular saw) The basic function of the expansion slots, which are used primarily on larger diameter blades is to create an outlet for heat buildup created during cutting.
Alternatively referred to as a bus slot or expansion port, an expansion slot is a connection or port located inside a computer on the motherboard or riser card. It provides an installation point for a hardware expansion card to be connected.
Non-melt plastic-cutting saw blades with modified triple-chip grind and 2° negative hook angle for less heat than a standard blade, leaving a crisp, smooth edge in acrylic sheets, Plexiglas®, Lexan®, corrugated polypropylene, HDPE, polycarbonates and more. Many sizes available. Great prices.
In a cutting disc which has a plurality of radial slots connecting with the peripheral edge of the disc, a transverse slot is located at the base of each radial slot. This transverse slot comprises a thin, arcuate slot positioned concavely to the peripheral edge of the disc. Each end of the transverse slot terminates in a hole.
A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern.
