Granite has become the go-to surface for bathroom and kitchen countertops, as well as fireplaces, outdoor stoves and any number of decorative and functional items found in homes and buildings today. Granite surfaces add an air of elegance and increase the value of any home. They also have the durability to last for the life of the home with minimal maintenance.
How Granite Cutting has Evolved
One of the most important elements of granite countertops and other surfaces is a perfect fit. The technology for cutting granite has improved significantly over the years to ensure that. This is a look at how the top granite retailers are able to provide perfectly cut stone.
Granite used to be manually cut. However, that method left dimples and ripples in the stone. With manual cutting, it was nearly impossible to get a precise countertop fit with no gaps. However, most fabricators (the people who actually craft the stone into countertops or other surfaces) now use machines to ensure that the stone matches the space where it will be installed perfectly, and is the precise shape and design that is desired. The most advanced tool is called the Computer Numerical Control (CNC) machine. The CNC machine does more than cut. It also saws, routes, etches and finishes the stone.
As the name says, the granite cutting machine uses computer-generated technology that allows manufacturers to get accurate measurements that are not possible with manual processes. It provides a perfectly straight cut. A CNC machine also can cut stone into shapes that allow the granite to be used for sinks, fireplaces, round tabletops and even carved statues.
How CNC Machines Work
After a design is made on paper, the fabricator translates it into a computer-aided design (CAD) program that will be interpreted by the computer, which directs the cutting of the material. In addition to granite, CNC machines can also be used for wood, plastics and aluminum.
Patterns can be programmed into a CNC machine to make the same item multiple times, which saves time and frees up fabricators to focus on the finishing. Unlike human beings, the machines can run 24-7.
When you go to a granite retailer, ask how their fabricators cut their granite. If the salesperson doesn't know, find someone who does. How the granite is cut is essential to how it will look and fit. Granite countertops and other surfaces are not inexpensive, and you want to ensure that what is installed in your home will be just as beautiful as what you see in the showroom.
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.
Stone Processing dominated by flat plate to the plane sheet, cylinder, polyhedron, curved body, carvings and other varieties of stone products development. Traditional processing methods, such as using a chisel and chisel were manually peeling and grinding stone processing, has a long history, but dust and labor-intensive, low efficiency, poor dimensional accuracy and surface quality. From this date the 1970s, have developed a variety of special machinery granite cutting machine, such as diamond wire saw, diamond sawing machine, vertical engraving machine, CNC machining centers, multi-function, its working efficiency greatly exceeds the manual processing, and stone implements industrial mass production.
1. Diamond Sawing Machining
Diamond Cutting Tools: superior cutting performance and wear resistance, is widely used in stone and many other industries, but the higher cost of diamond saw blades, and its direct impact on the life of stone processing costs. Therefore, the correct choice of the blade while cutting should be a reasonable process parameters to improve blade life and cutting efficiency.
(1) diamond saw blade wear
Wear properties of diamond saw blade cutting tool to reflect the performance of the reasonableness of one stone cutting process parameters, can be an important indicator of sawing workability.
A typical diamond wear process: diamond protrusion reach working height, crushing, abrasion binding agent, then a diamond blade, broken grains, grains completely off.
Diamond abrasive wear process, the ongoing micro-crushing, local crushing process makes the continuous generation of new cutting edge, the blade is sharp and cutting state, high cutting efficiency, cutting power consumption is reduced, but the reduced blade life; while diamond continuously polished and polishing the cutting edge will passivate the cutting force increases, reducing the cutting efficiency, and increased service life of the blade.
(2) cutting process parameters
Cutting process parameters, the greatest impact on the saw blade cutting speed and wear properties, it is mainly caused by changes in temperature and mechanical load sawing, resulting in different forms of diamond abrasive wear produced. In the low speed region, the mechanical load plays a major role for the blade to wear, increasing the cutting speed, cutting depth single diamond abrasive grains and the effective cutting area is reduced, so that the mechanical load decreases, the blade radial wear reduction small, diamond shape to wear polished, off the main; area at high speed, mechanical loads and thermal shock loads have a decisive impact on the blade wear, with increasing cutting speeds, thermal load and mechanical load shock effect increases, saws increased pad wear, diamond grit to break form the majority.
Changing the cutting depth and feed rate is mainly caused by changes in mechanical load impact blade wear. Increased cutting depth or feed rate, single diamond abrasive cutting thickness increases, cutting load increases, the blade wear and tear. In addition, increasing the cutting depth, but also to make contact with the rock diamond grit arc length increases, due to friction, wear diamond shape with polished-based, cutting edge becomes dull, so that the load increases cutting, sawing cutting process instability. Cutting rates at the same situation, when using a large cutting depth small feed rate, cutting diamond abrasive relatively reduced thickness, the cutting path length, wear and tear in the form of diamond grit to grind heat load caused mainly the reduction in the number of broken grains; when using small cutting depth, large feed rate. Diamond abrasive cutting thickness increases, the cutting path is short, at this time, in the form of diamond abrasive wear diamond to mechanical loads and shock effect caused by the broken main.
In addition, the shape of the blade itself, such as diameter, number of teeth, width, etc., as well as material selection coolant to the cutting process, such as the stone also has an important impact. Therefore, sawing stone, the need to consider many factors in order to obtain the best cutting results.
