Diamond segment grinding disc, more people call it diamond grinding cup wheel, it can used for grinding concrete, granite, marble, stone. It is metal bonded diamond tool with diamond segments brazed or sintered on a steel base body(or other metal, such as aluminum), which usually looks like a cup. diamond segment grinding discs are usually mounted on angle grinders to grind abrasive building materials like concrete, granite and marble.

There are 2 common ways to produce diamond segment grinding discs: hot pressing and cold pressing, you can also call it brazed and sintered diamond segment grinding disc.
 
The hot pressing technique is make the diamond segments in moulds beneath a particular pressure in the dedicated sintering press machine, then weld the diamond segments onto the steel base wheel via high-frequency welding(usually silver soldering), laser welding or mechanical technique(like fire soldering).
 
The cold pressing technique is to initial press the working layer (containing diamonds, cobalt, si, fe and other metal powder) and the transitive layer (not containing diamonds) of the diamond segments to their forms directly on the steel base wheel, then make the diamond segments connect with the wheel's body via teeth, slots or other different manners. Then, place the grinding disc into sintering furnaces to sinter without pressure.
 
The cold pressed diamond segment grinding disc has a better sharpness and lower price, but very short working life. The hot pressed(brazed grinding disc) one has an arelatively higher price, but much better quality and long working lifespan. ChinShine produce mostly hot press diamond segment grinding disc for the professional workers with high quality.
 
There are various designs and types of diamond segment grinding discs to suit varied application necessities. The ones with big segments can undertake heavy workloads, for example, grinding concrete and stone, whereas those with tiny or thin diamond segments(usually together with PCDs) are usually used for quick removal of paints, wallpapers, glues, epoxy and other different surface coatings. Some common type of diamond segment grinding discs are "single row", "double row", "turbo type", "PCD type", "Arrow type" and etc.

Like other metal bonded diamond grinding tools, the diamond segments on grinding discs can have different bonds(like very hard, hard, medium hard, soft and very soft), different diamond grits, different diamond quality and different diamond concentrations to fit different uses. For example, if the concrete is hard, the bond should be softer, and if the concrete is relatively soft, the bond should be harder. 
 
Diamond segment grinding discs are used in different roughness and hardness of concrete grindings. For coarse grinding, the bond should be softer and the diamonds’ quality should be higher, in this case the diamonds become blunt more effective. The diamond grit should be bigger, normally from 35 grit to 50 grit. For this is coarse grinding and big grit can improve working efficiency. The diamond concentration can be lower. 
 
For fine grinding, the bond should be harder, as in this case the diamonds can last longer and a hard bond can also help the precision of the process. The diamond grit is normally between 80 grit and 120 grit, depending on the grinding requirements. The diamond concentration should be higher.
 
After grinded, the concrete surface is often further polished with resin bonded diamond polishing pads from grits 200# to 3000#.
