Stack Core Cutting Machine – Find Many of The Internet Based Good Deals For Transformer Core Cutting Machines.

Professional methods of concrete sawing and drilling are prevalent in countries like USA, Japan, Australia and Europe. In India, it is actually still a young but growing industry. On account of a heightened spending on infrastructure projects and residential & commercial construction, India holds tremendous potential in terms of diamond tools and concrete sawing and drilling.

Another critical factor inducing the adoption of these sophisticated methods will be the constantly rising labour costs. Over the last decade, concrete and construction industry has experienced sharp increases in labor rates and overhead expenses. Due to the high labor and expenses associated with most sawing and Core cutting machine, the speed that the task is carried out has grown to be vital. Using outdated cutting &drilling techniques and drilling equipment that heavily will depend on guessing and operator testing only result in waste of money and time. Today, in order to remain competitive, the contractors are under pressure to embrace modern-day ways of concrete sawing & drilling.

“The niche for floor saws, wall saws and powered drilling machines happen to be in a nascent stage today but growing at about 40% each year as the fee for labor rises, the usage of machines to quicken work and increase productivity and quality of work will increase phenomenally. Presently about 600 machines Floor Saws, Wall Saws and High Powered Drilling Machines have been in operation. Low Powered Hand Held Drilling and sawing have been in many thousands and is particularly very difficult to give even an approximate number.” - M.Venkatesh, Executive Director, Diabu Diamond Tools

Professional diamond concrete cutting systems provides significant advantages over conventional concrete removal methods. Included in this are reduced downtime, precision cutting, upkeep of structural integrity, reduced noise, dust and debris, limited-access cutting, and the ability to cut heavily-reinforced concrete.

You can find hardly any organized players within the core cutting arena. Most of them are extensions of worldwide manufacturers like Hilti, TYROLIT, Husqvarna and Diabu. As with some other industry, the industry is flooded with Chinese equipment and fly by night traders who sell affordable, poor machines from China with the objective of making quick money. These machines, however, have zero post sales support nor will be the machines suited and made to are employed in the Indian environment. Mr. Akhil Jain, authorized and exclusive distributor of Husqvarna’s power tools in India says, “Users with low budget prefer to choose low quality Chinese makes only wind up spending much more on repairs.”

With regards to manufacturing facilities in India, approximately 25% are manufactured indigenously, the others imported along with the bulk provided by China. Hilti which acquired Bhukhanvala Diamond Systems during 2010 is applying it as a its manufacturing facility to help develop and expand the production facility for diamond tools and disks and to strengthen its position inside the Indian diamond consumables market.

“HILTI was the pioneer in introducing diamond coring technology in India. Throughout the last 5 to 10 years, the technology has matured into a stage where even on residential sites, coring may be the preferred technology for fast, vibration-free penetrations. We currently see the marketplace for coring at over 50 crores.” Shyam Raghunandan, Head Marketing, Hilti India

Manval Goel, Business Head - Construction at TYROLIT India Superabrasives Tools believes the industry scale of controlled concrete dismantling in India is in close proximity to INR 120 crores. This consists of branded and unbranded market too. TYROLIT has a wide range of core cutting electric, hydraulic and petrol driven machines. TYROLIT’s machines can perform drilling as much as 1000 mm diameters. Its Ultimate Drilling Machine (UDM) is actually a self-propelled gasoline driven transformer core cutting machine highly suited to drilling at runways. TYROLIT has 27 Global Production Units and its particular core cutting machines and drills are produced in Switzerland, Austria, U.S.A. as well as other parts around the globe. These appliances come with a manufacturing warranty of 1 year. Also these are generally quite sturdy machines and require suprisingly low mainte-nance. TYROLIT’s Unique Service Concept provides a few of the service requirement at site to care for emergency Breakdowns.

Diabu Machines has recently entered the Indian market. Designed keeping in mind the Indian working conditions along with the Indian operator, Diabu’s floor saws, wall saws and drilling machines are made on the platform of robust, rigid and productivity. Diabu uses high quality and right configuration steel, extended life and easy to maintain bearings, dust and water protected motors, bearings and all of sliding and rotating parts. Most if not all fasteners are produced from either steel or rust proof and tensile steel. Aside from being easy to use, maintenance can also be very simple with easy to access grease and oil points.

“There is a significant necessity for education about controlled dismantling being a technology within the construction industry. Other challenges correspond with acceptability and adaptability of the technology in a number of the major projects, drilling and sawing vis-à-vis the typical chisel and hammer, economics related to the technology as this is expensive, application with illiterate labor and localized availability of the technology.”

Choosing the proper blade (for the saw, the fabric and the job) is an essential aspect in getting maximum performance. All kinds of other variables also affect blade performance. Changing any variable can have an effect on cutting speed and blade life.

Concrete cutting being an application oriented process, blades are supplied according to end application requirement and job site requirements. The principle concrete cutting tools which can be utilized include the wall (or track) saw, the flat (or slab) saw, the core drill, and also the wire saw. Wall sawing is typically specified to reduce precise dimensional door, vent and window openings. Straight and also bevel cuts are possible with the wall saw. The wall saw is additionally an excellent selection for creating precise openings in any concrete structure. Flat sawing is normally employed to cut horizontal flat surfaces like floors, bridge decks, and pavement. Flat saws are typically employed to provide expansion joints, remove damaged pavement sections, clean and repair random cracks dexqpky76 repair, and remove concrete sections for demolition purposes. Core drilling techniques are being used when precise, circular cuts are essential including openings for plumbing, electrical and HVAC installations, creating holes for routing cables or placing anchoring bolts, installing load carrying devices or dowel bars, or for concrete sample analysis. Wire sawing can be used as removal of thick parts of concrete. It is ideal for removing large parts of heavily reinforced concrete, such as piers, towers and bridge sections, and cutting concrete in places that work space is fixed.

Often the decision of cutting wet or dry is dependent upon ones preferences and job requirements. While many sawing or drilling is wet, conditions such as water scarcity in sites, requirement to keep the web page clean of water/slurry on account of proximity with existing office/ factory /commercial/residential space, proximity to electrical or some other such dangerous areas may warrant dry cutting. However, cautions Mr.Venkatesh of Diabu, “If the cutting is dry it is always better to use saws that are laser welded or atleast have special reinforced brazing. Using such blades be sure that the extremely high heat generated during dry cutting will not damage the blade which might also cause injury and cause accidents.”

Apart from the form of cutting and dry or wet cutting, types of concrete also influence the choice in choosing a blade. The duration of curing time after concrete flows greatly affects the way a diamond blade will interact with it during cutting. Curing can be affected by weather (temperature, moisture and season) as well as the composition (admixtures, aggregate and sand). Cured concrete is usually set a minimum of two days. The sand is completely bonded together with the mortar and also the concrete reaches full hardness. Concrete is typically in the green state for 6 to 48 hrs after it can be poured. In this early state, the sand is not completely bonded with all the mortar and the concrete doesn’t reach full hardness. When cutting green concrete, the sand loosens more readily, and flows more freely from the slurry, and produces considerably more abrasion over a diamond blade. Undercut protection is crucial when cutting green concrete to prevent excessive wear on the steel core on the segment weld. Green concrete sawing is normal when focusing on new construction projects for example; motorways, runways, driveways & industrial flooring.

Both size and kind of aggregate have a great influence on the general hardness of concrete as well as the blade to decide on. The aggregate can make up around 75% from the total volume. As a general rule, larger aggregate is likely to make the concrete act harder, slowing drilling process. Smaller aggregates tend to make a blade cut faster. Sand is part of the aggregate mix, and determines the abrasiveness of concrete. “Small aggregate” is usually sand. Sand can either be sharp (abrasive) or round (non-abrasive). To determine the sharpness of sand, you need to know the location where the sand is from. Crushed sand and bank sand tend to be sharp; river sand is normally round.

Choice for core drilling operation may also requires learning the diameter of your final hole required, surface finish of your drilled hole, surface and accessibility from the drilling area.

“Tool horsepower, tool reliability and simplicity of use may also be necessary for selecting the most appropriate tool”, adds Mr. Shyam Raghunandan of Hilti, India.

Manav Goel, of TYROLIT summarizes, “Overall, factors such as diameter from the core, entire core, power and speed of motor, percentage reinforcement, grade of concrete, horizontal or vertical drilling, Transformer core cutting machine, anchor or vacuum fixation assist in deciding which concrete core cutter to use for the project.”

Conventional concrete cutting and drilling methods generated a lot of dust. While wet cutting or drilling operation does not generate dust mainly because it uses water, the instance of dust is virtually totally avoided. However, the slurry generated should be cleaned regularly. For dry cutting, most manufacturers have dust extraction systems as accessories.

In addition to saw speed, the ease of transport and installation is important in jobsites which may have single doors or window openings to become remove or where the saw has to be constantly moved from one floor to the next. Some machines are employed in a modular system thus attracting certain advantages, because the single component might be easier transported and installed.

When it comes to costs, these machines are not very expensive machines and if regularly maintained, the cost of maintenance can be kept as low as any machine a yearly spend of approximately 6% - 10% of the buying price of the device.

The popularity is clearly lighter, lesser, faster and much more profitable. But what comes along with this development is actually a stronger demand that operators be trained effectively. Also, contractors ought to be made aware or there must be experts who can suggest the very best techniques and equipment for the best efficient and cost-effective cutting at any stage of the project.
