Diamond Cup Grinding Wheels

Diamond cup grinding wheel refers to the diamond segments are pressed or welded on the metal base. Diamond segments are cold or hot pressed sintered by synthetic diamond powder and other metal power, and then welded on the bowl-shaped metal base. Diamond cup grinding wheels are available in different types and sizes for grinding concrete, stone, as well as paints, glues, epoxies and other floor coatings.

Types of Diamond cup grinding wheels:

  • Metal sintered diamond cup wheels: hot pressed or cold pressed sintered
  • High frequency welded diamond cup grinding wheels: High efficiency and good wear resistance.
  • Vacuum brazed diamond cup grinding wheels: Superior performance and high price, mainly used for shaping and edging of the stones.
  • PCD grinding wheels: Weld the PCD on the metal base and used for floor coating removals such as epoxy and paint.

Selection of diamond cup grinding wheels:

There are iron base and an aluminum base. The iron base is widely used. The aluminum base is light and is more suitable for angle grinder. The common shape is turbo, and sizes are 3 inches (80mm) and 4 inches (105mm), which are used for surface grinding of granite, marble, and other stone. Diamond segments have different carcass, different grit, and diamond concentration. There are hard, medium, soft and etc. for carcass and coarse, medium, fine grit size. We choose the right diamond cup grinding wheels according to the application. For example, when grinding hard ground, we should choose the cup wheel with the soft carcass. If it is fairly soft ground, we should choose a hard carcass. For ground grinding with different roughness, we should choose the right grit size of the cup wheel. Usually, for coarse grinding, we should choose softer carcass and high-quality cup wheels with large grain sizes such as 16#, 20#, 30/40#. For fine grinding, hard carcass and fine grain size such as 80#-120# are used. Connector: 22.23mm, M14, 5/8”-11 Sizes: 4”, 5”,6”, 7”, 9” Grit: 16#, 20#, 30#, 46#, 60#, 120#, 200#, 300#, 400# Segment shapes: single row, double row, turbo, L shape, arrow shape, and etc.
