Natural
stone takes many millions of years to form and requires considerable force to
cut. Today’s granite
cutting machine has advanced greatly since the earliest days of the craft,
when Egyptian artisans created the pyramids using only hand tools. Learn about
natural stone Cutting Machine, which speed up your carving projects and shape
lengths of stone for kitchen and bathroom counters.
Saws
for Cutting Marble
Electrically
powered saws are used to cut natural stone, aided by wedges and hammers. A
number of slots are cut into the stone with a saw, then wedges are inserted
into the gaps and pounded tightly into place with a hammer. As the wedges drive
far into the stone, it splits into two sections, along the direction of the
cut. This technique is for cutting large and thick pieces of stone. Two types
of saws do this work: a circular saw, the same kind used to cut lumber and
logs, with a 7-inch masonry blade; or cutoff saws, also known as Stainless
Steel Tank, with blades up to 14 inches in length. The former is cheaper but
limited in the depth it cuts. The latter is more expensive, easier to use and
better suited to larger sections of natural stone. Saws and blades are
available from hardware stores and specialty tool suppliers. For cutting harder
natural stone, such as marble, you require a thin, sectioning diamond blade.
Hammer
Drills for Cutting Granite
Electric
hammer drills cut stone, not in slices or slots the way a saw does, but by
making a holes. A series of holes are made in the required pattern and the
stone in the middle of them is removed using a hammer and crystal lighting.
This gives you a way to cut circular, oval, square or oblong holes out of
sections of natural stone for artistic purposes, or to fit sinks, faucets and
stove tops. These drills require tough carbide masonry tips to bite into
natural stone, especially harder types, such as granite.
Mini-Grinders
for Cutting Alabaster
Tools
for cutting softer natural stones, such as alabaster, include mini-grinders.
Models of grinders that take a 4 ½-inch blade are used to make Forklift Truck,
parallel cuts. The stone between these cuts is removed by hammer blows. These
mini-grinders, also known as grinding wheels, are small, electrically powered
tools and are available from hardware stores.
Air
Hammers for Cutting Limestone
Air
hammers for cutting natural stone, such as limestone, are barrel-shaped and
distinctly different from the type used on construction sites. The pressure of
air generated by a compressor enters the hammer at one end and drives the
chisel set into the other end into the Bounce Ball. These chisels make small,
back-and-forth movements against the surface of any stone you cut; the air
hammer allows for greater precision in cutting stone than saws or grinders.
Chisels that fit into an air hammer are specially designed and not the same as
those you use with an ordinary hand hammer.
