Mainly used on hand-held grinders for rapid grinding and smoothing of concrete surface along edges, columns where floor grinders can not reach. Popular sizes of double row diamond cup wheel that used in concrete polishing industry are 5inch, 6inch and 7inch. Number of segments varies with sizes. Metal base of cup wheels comes with venting holes to dissipate heat when used dry. Those holes also reduce weight of the cup wheel making it workable on hand-held grinders. Non threaded 22.23mm bore, threaded 5/8–11 or m14 arbor are both available. Soft, medium and hard bond are available for different hardness of concrete floors. Extra soft, super soft, extra hard and super hard are also available if needed.

General grits 30#, 50#, 70#, 100#. Coarse grits usually with softer bond, higher diamond toughness and lower diamond concentration to produce faster grinding and improve overall working efficiency. Fine grits usually with harder bond, lower diamond toughness and higher diamond concentration to produce smooth finish. In concrete polishing industry the cup wheel is mainly used on hand-held grinders for grinding and smoothing of areas where floor grinders can not reach

There are two rows of segments on the cup wheel. The first row with longer segments laying along the outer edge and the second row with shorter segments staggered arranged. The design helps to keep cooling water detained in the space between segments when in wet application and to provide channeling for dust when in dry application. With plenty of segments double row diamond cup wheels work smoother and last longer. Unique formula with premium quality diamonds ensures aggressiveness of the cup wheel. Diamonds are distributed throughout metal powders evenly, professional hot pressing and welding ensure longevity of the cup wheel. Every cup wheel is balanced to eliminate vibration and chipping. Color of cup wheel can be different as per grit number or as per bond hardness or as per customer request.

Basic Knowledge About Double Row Diamond Cup Wheels

The double row diamond cup wheels comes in variants of different specifications. According to the application type, the cup wheel category is selected. For example, heavy loads like concrete and grinding stone would require a diamond wheel cup with a huge diamond segment. On the opposite hand, smaller diamond segments fit perfectly for lighter works, including glues, paints, epoxy, and other surface coatings. Therefore, it's imperative first to work out the character of the task ahead. Depending on the hardness of the surface, thedouble row diamond cup wheels generally exists in two phases.

It consists of coarse grinding. In this phase, diamonds possess a high propensity to become blunt. It occurs because adouble row diamond cup wheels quickly blunts out when operating on hard surfaces. Thus, a soft diamond bond with high diamond highness is suitable for this phase. It involves fine grinding or polishing. It requires the utilization of a tough bond thanks to its superior precision. However, as a diamond doesn't disintegrate quickly, a soft diamond will do the work briefly. Grit between 80 to 120 is right at this phase, while the concentration must be set high. Thedouble row diamond cup wheels has two significant parts- the cut of abrasive grains and the bond between abrasive grains. The mixture of the grain, bond, and therefore the spacing between the wheel form the structure. You want to consider the share also. The precise abrasive that a cutting wheel uses mostly depends on its interaction with the work material.

A perfect abrasive self maintains itself through automatically sharpening. The abrasive fracture works by establishing new cutting points when dulling set in. However, there's a particular feature for every abrasive type in terms of strength, hardness, resistance to impact, and fracture toughness. Abrasives are available in three primary forms. It includes alumina, zirconia alumina, and carbide.

Things To Look For in Double Row Diamond Cup Wheels

The diameter of the wheel matters based on the type of material you are grinding or polishing. Wheels with larger diameters have more segments and give a smoother result, while smaller wheels are more prone to leaving scratches behind. The density of the diamonds in the grinding segment also affects the outcome. A continuousdouble row diamond cup wheels has a rim that is completely covered in diamonds and is suitable for polishing and smoothing fine surfaces. Grinding wheels may have single or double rows. Most diamond grinding wheels have segments, spaced apart from each other, attached at intervals to the wheel. Larger segments are suitable for grinding very hard surfaces. Smaller segments do a good job removing adhesives and paint.

Grit is a measurement of coarseness: the lower the grit, the coarser the diamonds, meaning they are larger and spaced farther apart.double row diamond cup wheelss with a higher grit rating have finer diamond surfaces, with either continuous diamond surfaces or more closely spaced segments. These are suitable for polishing stone, concrete, and other materials to a high sheen. Like diamond saw blades, the bonding agent that adheres the diamonds to the surface of the wheel makes a difference. Soft bonds grind away, repeatedly exposing new, sharper diamond crystals. Hard bonds don’ t grind down so easily. Remember that ‘opposites attract’ when it comes to bonds on diamond cutting or grinding tools. Soft bonds are best for hard materials, and hard bonds are good for softer surfaces.
