  • Why diamond core bit segment broken during coring?
    Oct 22 , 2015

    Why diamond core bit segment broken during coring?

    Sometimes in the world of concrete core drilling we face the frustration of loosing a core bit segment or two while drilling, more times than not it’s that urgent job that must be done NOW. So let’s take a look at WHY this might happen. This is written in regards to wet series concrete diamond core drill bits Manufacturing Fault One possible cause could be that a core bit segment might not have been brazed or laser welded on properly. If this is the case, the diamond core bit segment will more than likely come off within the first hole. Usually in the first 50mm depth of cut. To determine if this is the case, where the core bit segment is missing from the barrel, it will look and feel smooth. You will notice that the diamond drill segment is also rather smooth on the surface that was welded to the core barrel. This is most likely with brazed core bits. Don’t assume that just because a segment has come off drilling your first hole that it is a manufacturers fault. It can just be unlucky that it was your first hole and something within the slab or material has caused it to happen, which leads to the next possible causes. 2. Debris and loose particles. More often than not, a diamond core bit segment comes off or breaks because of debris within the hole you are drilling. This could be a piece of reinforced bar that has somehow become lodged between the segments while drilling. It could be something else like a piece of stone thats been dislodged. Sometimes it is hard to determine exactly what caused it to break off in this instance. If the diamond core drill bit has been used numerous times and then a diamond core bit segment comes off while drilling into the material it is safe to say that it is not a manufacturing fault. 3. User Error Yes, it could actually be your fault! Have you got water flow while drilling? Are you using the correct drill type and speed for the diameter size? Are you applying too little pressure to cause vibration? If your drilling through a concrete slab, are you pulling up before it hits the fill or debris beneath? Do you feed enough water? There are many reasons why diamond core bit segments can break or snap off. The above were just a few examples which came to mind while writing this.

  • What is the diamond segment welding technique? How to weld diamond segments correctly?

    What is the diamond segment welding technique? How to weld diamond segments correctly?

    There are three methods to weld diamond segments onto the saw blade core: silver/copper welding diamond blade(brazed), wholly sintered diamond blade and laser welded diamond blade. silver/copper brazed diamond blade: diamond segments are brazed to the steel saw blade core by using a silver solder. Silver brazed diamond blade can only be used in wet cuttings. If they are used in dry cuttings, the silver solder may melt under the high temperature generated in the dry cutting and the segments can break from the steel core and be extremely dangerous. People use high frequencey machine or fire to weld them on blade blank. Wholly sintered diamond blade: the diamond blade is made by putting the steel core together with the diamonds and the metal bond materials(metal powder) into a mold and then sintering them in a sintering machine. Laser welded diamond blade: the laser melt the diamond segment and the steel core creating a stronger welding, which can hold the diamond segments even in high temperatures, so laser welded diamond blades can be used to cut many types of materials without water cooling.

  • Use Dry Or Wet Diamond Blade While Cutting
    May 26 , 2014

    Use Dry Or Wet Diamond Blade While Cutting

    Diamond blades work best when cutting wet. The water will prevent the diamond blade from overheating and distorting in shape, it reduce harmful dust created by cutting, and will remove the slurry from the cut. Diamond cannot withstand the forces involved at the elevated temperatures of dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure. Blade life is greatly extended by wet cutting. However, many saw blades are designed to operate either wet or dry. Dry diamond blade should be limited to situations where water isn't available easily or used in electrical saws machine. When doing dry cutting, the diamond blade should be allowed to cool off periodically. Cooling can be increased by allowing the blade to spin freely out of the cut. Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting. This allows cool air to pass between the segments. Dry diamond blade cutting is dangerous for persons unfamiliar with the risks and process. After choose the right diamond blade, how to let diamond blade to cut faster? If the blade starts to cut slower than normal, the best way to adjust this problem is to find a hard surface like cured concrete and drop the level of water you are pumping over the blade. Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting. Sometimes, people found their diamond blade is easy to distort. Many people apply more pressure to the saw to force the blade harder into the material when it’s not cutting as fast as they would like, but this can cause the blade to overheat and distort in shape, throw a segment, this is unsafe for the operator and bad news for the diamond blade. Generally speaking, it is better to cut with water if the condition allows.

  • How do you choose the perfect diamond circular saw blade?
    Mar 12 , 2015

    How do you choose the perfect diamond circular saw blade?

    Generally speaking, cutting hard or abrasive subjects such as granite, marble, brick, concrete, asphalt, steel and other similar subjects, diamond circular saw blade has carved a nice in the global industry for the outstanding performance in cutting. Choosing the right diamond saw blade for cutting is necessary condition to perform a cutting task well. Before buying diamond circular saw blades, you should consider the following items, 1. What material you are cutting? The match of the diamond circular saw blade's features as closely as possible to the material you are going to cut, for example, cutting stone, granite, marble, concrete, asphalt, and so on. Correctly identifying the material you are going to cut is the most important factor in choosing a blade. 2. Choose wet or dry cutting? When using power tools such as power hand saw, it is not safe to use water because of the electrical power source. However, diamond circular saw blades for concrete are usually for wet cutting because the concrete to be cut is very hard or abrasive. If the diamond circular saw blades are used without adequate water, the diamond segments themselves may break or the steel core below the segments may wear and break, and then the segment may fly out and may hurt the operator or people nearby. If you have to perform dry cutting for some reason, you should choose sharper diamond circular saw blades, and the dry cutting should be intermittent and shallow to keep the circular saw blade cool. 3. What is the height of diamond segment? Total diamond segment heights may be misleading because of non- diamond bearing segment bases necessary for the laser welding or brazing process. Many other factors affect a blade’s performance and consequent value. Consider the diamond size, concentration and quality, the hardness of the bond, the cutting power (torque) of the saw, and how well the circular saw blade specification is matched to the material being cut. 4. How to choose optimum performance tools? Is it the initial cost of the blade or the total saving cost? For larger projects or regular use, a higher priced blade will actually be less expensive to use because it will deliver the lowest cost per cut. For a small cutting job, you can buy the economy saw blade or cheap diamond circular saw blade.

  • The Principle of Diamond Wires Cutting from China Diamond Wires Suppliers

    The Principle of Diamond Wires Cutting from China Diamond Wires Suppliers

    In the 1990’s, in order to solve the processing problem of large size silicon wafer, jigsaw machining technology are widely used to cut large size silicon wafer into segments and pieces in the international marketing. Early jigsaw machining technology applied bare wire and free abrasive. In the process of machining, the free abrasive are added into wire and mechanical parts as the third party to cut. This technique is successfully used in processing of silicon and silicon carbide. In order to further shorten processing time, as well as on other hard material and ceramic, diamond abrasive will be fixed to a metal wire in a certain way, which compose a fixed diamond wires saw. As shown in figure, cutting lines with high-speed reciprocating motion drive the slurry to the cutting area, which makes the abrasive particles (SiC particles) in the mortar and the surface of silicon rod make high speed grinding. Because the abrasive particles have very sharp edges and its hardness is greater than the hardness of silicon rods, the contact area of silicon rod and diamond wires saw are grinded out gradually by mortar. Thus the effect of cutting will be achieved, and meanwhile the mortar also can take away a lot of hot produced in the grinding. In the process of cognition of diamond wire saw cutting mechanism, many researchers believe that the micro cutting movement of diamond grits is a scroll and embedded process. They put forward the "scroll - embedded" model. Li and some reachers put forward diamond wire sawing force drives on the abrasive grits rolling along the cutting surface, squeezing and embedded abrasive cutting surface at the same time. Consequently there is a flake piece of chip and surface crack, forming the big cutting function. Kao and other researchers pointed out that in "scroll - embedded" model, the particle movement also includes scratches, in addition to the rolling and embedded. All three work together for cutting. Bhagavat and some researchers considered the effect of pulping in this model and believe that the diamond saw wire leads free abrasive cutting silicon ingot of small area, and the movement of diamond wires saw and grinding pulping form a elastic fluid dynamic environment. They can use the finite element method (fem) to analysis the elastic fluid dynamics model of diamond wires saw and silicon ingot to get the function of diamond wire walking speed, viscosity of grinder and cutting conditions. Then they draw the conclusion: pulping film thickness is greater than the average particle size, is the flow of the abrasive cutting.
