what types of diamond grinding shoes

Diamond grinding shoes are a type of tool used in the concrete polishing and preparation industry to grind or polish surfaces. They are designed to help remove coatings, prepare surfaces for further treatment, create a specific surface profile or texture, and generally improve the appearance and durability of concrete floors.

There are several types of diamond grinding shoes available in the market, each designed to achieve specific grinding or polishing results. Some of these types of diamond grinding shoes are described below.

1. Metal Bond Grinding Shoes – These diamond grinding shoes feature a metal bond matrix designed to help remove coatings, level uneven surfaces and grind down concrete edges. They are also useful in preparing surfaces for further treatment. They come in a range of bonding strengths, from soft to hard, and are used depending on the type of concrete being ground, the desired finish, and the grit size of the diamonds.

2. PCD Grinding Shoes – PCD (polycrystalline diamond) grinding shoes are designed for use on coatings, epoxy, paint and other materials that are difficult to remove with conventional diamond grinding shoes. They are also used to level concrete surfaces and remove high spots, but their primary function is in grinding down thick coatings and adhesives. PCD diamond shoes are made from diamond chips that are bonded to a carrier material, such as metal or resin.

3. Resin Bond Grinding Shoes – Resin bond diamond grinding shoes are designed for use on softer concrete and are used for polishing floors to different levels of glossiness. They are available in different colors and hardness levels to suit specific grinding and polishing applications. They can come in a range of bond strengths to match the hardness of the concrete being used, and are available in a variety of grit sizes.

4. Hybrid Grinding Shoes – These are a combination of metal bond and resin bond grinding shoes that provide a balance between the aggressiveness of metal bond and the smoothness of resin bond. These shoes are ideal for grinding and polishing all kinds of concrete surfaces and are suitable for use in both wet and dry grinding.

5. Velcro Grinding Shoes – Velcro diamond grinding shoes can be easily attached and removed from the grinding machine. They come in various shapes and sizes and are suitable for grinding and polishing of concrete, marble and granite surfaces. The advantage of velcro grinding shoes is that they can be easily changed without the need for any additional tools.

In summary, the type of diamond grinding shoes used in the concrete polishing and preparation industry will depend on the specific application, the type of concrete being ground, and the desired finish. The right grinding shoe selection will ensure the best possible outcome and increase the lifespan of the grinding tools and equipment.
