Diamond grinding tools are used for ground leveling and rough grinding. Don’t use coarse sanding discs if fine sanding discs can be used to deal with matters. Increasing the rotation speed can increase the rate. Try not to skip the number of grinding tools. Dry grinding saves more consumables than wet grinding, but wet grinding will make the ground more uniform and delicate. After washing the ground and drying it, using polishing pads to do high-speed dry polishing is better. Using sponge polishing pads can improve floor brightness.

Factors Affecting Diamond Tools Selection

1. The flatness of the ground

The ground by manually troweling and leveling or the loose and severely damaged old ground, it is necessary to level or remove the loose surface layer, and it is necessary to use a high-power grinder, and choose diamond tools with strong grinding force, such as a concrete diamond grinding tool, which is suitable for leveling.

Cement self-leveling ground or mechanically leveled ground has better flatness, only diamond resin grinding pads can be used to make beautiful polished floors, and they are also more economical.

2. The hardness of the ground

The concrete used in the design and construction of the concrete floor is represented by the label, which is what we usually call C20, C25, C30, ec. Under normal circumstances, the higher the label, the better the strength and hardness of the concrete, but due to various influence factors, the label of concrete and the hardness of the ground often do not correspond.

The hardness of concrete floors is usually expressed by Mohs hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can use some substitutes to replace the Mohs hardness tester to know the hardness of the ground: the hardness of the nails and keys can be used to draw depressions and damages. The hardness is less than 5, otherwise the hardness is more than 5.

3. The weight and speed of the grinder

Floor grinders are usually divided into small, medium and large. Generally speaking, the larger the machine, the higher the power and the higher the rate; in actual use, the bigger the machine is not the better. Although the grinding rate is high, the grinding machine that is too large and heavy will often lead to excessive grinding and increase the construction cost. Experienced workers will adjust the machine speed, moving speed, number of grinding tools and machine counterweight according to the machine point to reduce construction costs and improve construction rates.

4. Types and grits of grinding tools

The commonly used abrasives for floor treatment are PCD abrasive tools, metal abrasive tools and resin abrasive tools. PCD abrasive tools are used to remove thick coatings on the surface of floors, and metal abrasive tools are used for floor surface pretreatment and rough grinding. Resin  abrasive tools are used for surface rough grinding, fine grinding and polishing.

The grits refers to the size of the diamond particles contained in the abrasive tools. The lower the number is, the larger the particle is.

Metal grinding tools are usually divided into 30#, 60#, 100#, 120# and other numbers. Which grit to use should be determined according to the ground conditions. For example, if the ground flatness is not good or the surface is relatively loose, it may be necessary to use 30# metal diamond tools for the ground to remove the loose surface layer to level the ground; resin diamond tools are widely used, with a grit range from 30#-3000#. Different grits are distinguished by different colors, which are used for rough grinding, fine grinding and polishing of the ground. Resin diamond tools are divided into hard polishing pads and soft polishing pads. Hard polishing pads are suitable for medium and large-scale floor grinders to level; soft polishing pads have  better polishing and they are suitable for various types of floor grinders.
