Diamond Blade Become Blunt The bond of diamond segment is too hard; read the diamond blade instruction and check if you are use the right diamond saw blade. Glazed segments can be opened up by cutting the abrasive material, such as brick and concrete. Make sure the cutting saw has enough horsepower for the diamond blade, you can also check if the drive belts of cutting saw need tp be retensioned. Blade Blank Loss its Tension To make a premium quality diamond blade, not only about the quality diamond segments, but also about the blade blank.  If blade blank loss tension, maybe the steel blade blank has been overheating. Ensure sufficient water supply for wet diamond cutting blades. If the diamond segment bond is too hard may causing the blade to deviate the cutting. Check machine is running at the correct RPM that there is no wear on machine bearing shaft and that the flanges are in correct and same size. Ensure diamond cutting blade is secure and not spinning on the spindle. Check that the drive pin is in right place.  At last, make sure that the diamond saw blade cuts in straight lines only. At last, if you can't find out the problem, check if the blade blank has been used for many times, you may need to change a new diamond saw blade. Diamond Blade Overheating During Cutting Overheating is the common cause of diamond blade failure, overheating causes problems such as loss of tension, blade blank cracks, diamond segment broken and even drop off.  People can see the diamond segment or close to the segments become black. For wet diamond saw blades, inadequate water supply can be caused by blocked or damaged feed inlets. Trickle feed for dust suppression van cause excessive abrasion. Do not let diamond blade cutting under heavy pressure, diamond saw blade cut freely is the best way. Uneven Diamond Segment Wear Off Wet diamond blade cutting without feeding enough water, generally on one side of diamond segment. Check water feeding system, ensure water is equally distributed to both sides of the diamond blade. Diamond segment is worn out of round due to bad bearings or worn shaft. Replace good quality bearings or shaft as required. Segments worn in one side reducing side clearance (check alignment). Check wheels and wheel alignment on cutting saw. Diamond Blade Out of Round Diamond blade shaft bearing may be worn. Change new bearing and ensure regular lubrication. The diamond blade is too hard for the material being cut, resulting in the diamond blade hammering and glazing. Choose right diamond blade with a softer bond. The machine spindle may have a groove scored in it as a result of a previous blade slipping on the spindle. Steel Blade Blank Cracks Diamond segment is too hard for the material being cut. Excessive cutting pressure, resulting in the blade blank bending and flexing. Insecure mounting causes fluttering of the blade. Ensure diamond blade is correctly mounted, drive pin used clamp nut is tight...

Diamond stone saw blades are the diamond tools that practically used for cutting granite, marble, sandstone, basalt and other natural stone blocks, slabs and tiles. The diamond stone saw blade is also well known as diamond cutting disc, diamond saw blade, diamond cutting blade. Diamond saw blade isn’t anything new as it has been the primary cutting and grinding stone for decades. Diamond saw blade, as the name suggests is used for cutting and sawing stone for various purposes. Different diamond segment formula are welded on blade core in order to deliver the right cutting results. For medium size saw blade(250mm to 600mm), diamond stone saw blade is a power tool used for cutting various granite, marble, limestone, ceramic, concrete, and many more super hard material. There are different kinds of diamond saw blades including small hand-held cut-off saw, angle grinder saw, table saw, brige cutting machine, stone block cutting machine. The diamond stone saw blades often been used on stone saws, such as angle grinder machine, stone bridge machine, block cutting machine, this means that they have diamond segments welded on steel blade blank to the main working component of the saw blade. The major resistance produced in cutting stone materials like granite and marble cause the high temperature and dust, it requires the technology to be cooled down the diamond stone saw blade and remove the chipping out, prolong their life and decrease the amount of dust. The operator of the diamond stone saw blade must be qualified to do the job, because it requires skilled experience in operating the stone machine.  For other hard material to be cut, use different diamond saw blades. There is unique diamond saw blade to match the exact requirement of every object to cut. Related Articles: a. Best stone diamond saw blade supplier? b. How to choose the right diamond saw blade? c.

Before start to cut, wear gloves and eyeprotection. 1. Buy the laser welding diamond cutting blade, the blade core contain cooling holes, it maybe clearly marked for dry cutting on blade. 2. Remove water tube from the cutting machine and turn off the electric water pump. 3. When start to cut, do not cut deeply at the very beginning, better cut step by step for the dry cutting. For the thick or deep cutting on concrete, keep the concrete cutting blade moving up(not cutting) and dropping down(cutting), this can let the diamond concrete cutting blade cool down. 4. Dry cutting only in large open areas, keep air flowing.

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.
