Bond bonding capacity of particles called Wheel hardness. If the binder particles are bonded tightly, it would be hard-grinding wheel, combined with particles bonding agent is not soft on the wheel too tightly. Determination of hardness wheel can be used for certain equipment. However, according to the sand sound transmission line can be roughly determined. When we use lightly metal Each wheel is on the towel labels indicate manufacturing brands, abrasive, particle size, binders, hardness, size specifications, the speed of work, manufacturing date and so on. Under normal circumstances, marked only factory brand, size, hardness and speed. We can wheel performance, combined with the need for choice.

 

Grinding with the thickness and amount of surface grinding wheel size and speed of the relevant circular. To a certain feed rate, the smaller the surface grinding, grinding the greater thickness; the greater surface grinding, grinding thickness can be less. Are the same size and quality of the grinding wheel, grinding traffic circle, the faster the greater the contrary, if the circumference of slow, grinding thickness of less.

 

When the same wheel speed, large-diameter wheel in a certain period of time, grinding a long journey, the thickness of the large grinding. Direct Mody small wheel, grinding a short trip, the grinding on the thickness of the small. For example, the use of vertical devices automatically send Grinding Machine Tool, the new film will be grinding wheel, grinding may be due to the large thickness, the amount of horizontal feed can be bigger, less able to travel again, after grinding wheel gradually reduce the wear and tear, grinding Less, so the horizontal feed the appropriate amount to more small and repeated trips to be more appropriate.

 

Grinding Wheel selection, should be processed in accordance with the nature of the pieces of material, in general, the tensile strength of the small, fragile materials such as the large cast iron, bronze, and so on, should be understanding and silicon carbide abrasive wheel; tensile strength, toughness large material, such as Carbon steel, alloy steel, high-speed steel, and so on, should alumina abrasive wheel. Because the brittle silicon carbide abrasive, if used to wear big tensile strength materials, abrasive easily broken following the loss. Alumina abrasive brittle relatively small, but not as sharp silicon carbide, the hardness will be lower, if it is used to mill small tensile strength materials are inappropriate for large fragility.
