Wheel Dimention Classification

Wheel Diameter x Wheel Thickness x Bore Size (mm)

Example : 180 x 6 x 22mm

This will indicate a wheel diameter of 180mm, thickness of 6mm and a centre bore size of 22mm. The wheel diameter has a direct correlation to the type and size of power tool that we are using. A 180mm wheel would mean that a 180mm Grinding Machine would be utilized. Likewise, if a 355mm wheel is being used, similarly a 355mm Cut-Off Machine would be in use.

Abrasive Type Classification

TAILIN abrasive classification can be broken down into the following categories.


Abrasive Grit Classification

The abrasive grit classification is a series of numbers assigned to denote the level of roughness or coarseness of the abrasive grain. It starts from 1 and the number can go right up to 1000. A typical classification range is as follows.

Rough : 1, 6, 20, 24
Medium : 30, 36, 46, 60
Fine : 80, 100, 120, 150, 180, 220, 320
Super Fine : 400, 600, 800, 1000

The grit size assigned for each type of wheel clearly indicates a particular usage purpose. For example an abrasive with grit 24 coarseness is clearly meant for high stock removal with less emphasis on finish appearances. On the other hand a finer grit of 240 will mean a much greater emphasis on polishing and finishing outcomes rather the stock removal.

Abrasive Hardness Classification

The abrasive hardness classification is a series of letters assigned to denote the level of hardness of the abrasive type and grit. A typical classification range is as follows.

An L-grade would mean a softer abrasive which in turn means faster grinding or cutting action. On the other hand a U-grade will indicate a harder abrasive grade which in turn points to a wheel with a longer life-span.

The abrasive grains are bonded in accordance with the Resinoid Bonded methodology. Resinoid bonds are formed by thermosetting phenolic resin. These resin bonds are cured by heating in ovens under carefully controlled conditions at selected temperatures between 150°C and 200°C. Resinoid wheels are tough and less brittle therefore making them ideal for heavy duty operations or high operating speeds, usually with the aid of fabric or steel ring reinforcement.\

The most common material used for wheel reinforcement is Fibreglass netting. All wheels come in either 1G (1 layer reinforcement) or 2G (2 layer reinforcement). The number of reinforcement depends on the thickness of the wheel and operator safety requirements.

Maximum Speed
The maximum speed of the wheel is classified as Revolutions Per Minute (RPM) or Meter Per Second (M/S). Most wheel maximum speeds will correspond directly with and will not exceed the operating speeds of the power tools being used.
