B. How to Choose an Abrasive Wheels
1). Good grain uniformity without crack-like apperance is the basic apperance of a high quality wheel.
2). Superior packaging and anti-couterfeiting labeling are the differences between certified products and fake products.
3). The lower static unbalance value, the better the wheel is. For sure the producing difficulty will be bigger.
4). The general rule of cutting and grinding: low cutting or grinding ratio and abrasion come from too hard wheels. Low ratio and high abrasion are the result of bad raw material used. Excellent quality includes higher efficiency and ratio, less abrasion as well as good hand feeling to cut or grind.
5). For different materials such as carbon steel, alloy steel, cast steel, stainless steel, copper, aluminum, glass and stone etc., we choose different types of abrasive wheels according to the different density and heat generating condition of wheel materials. In market, there are special abrasive wheels for glass and stone. Abrasive wheels with low thickness or zirconia grains are for copper, aluminum and solid stainless steel. Abrasive wheels with high hardness are for carbon steel and stainless steel (hollow) to increse the lifetime. As for solid round steel and cast steel, we should choose the type with not high hardness so that if can work successfully.
6). If you consume a large amount of abrasive wheels for certaiin materials, normally it's impossible that you can find the most suitable in the market. Please contact us with no hesitation and advise your situation. Then we will produce specially for you and offer our products at our best price.

C. Storage and Transportation:
1). Transport with complete packaging, no collision, not be exposed in damp for long and keep away from alkali objects.
2). Pile flat, no incline and pressure to avoid deformation.
3). Avoid piling on ground directly, piles on wood pallets, 10-15cm high away from the ground and less than 1m height.
4). Use the products according to expiry date and the general rules of first out, to ensure that the best usage period.
5). Products over one year should be re-tested rotary speed and strength, checked apperance before using.

D. Fault Causes

* Depressed Center Wheels

1).Low performance
a. Wheel bonded too hard
b. Low power output of portable grinder
c. Grinding pressure too low
2).Worn out quickly
a. Grinding pressure too high
b. Wheel bonded too soft
c. Rotation of grinder too high
3).Circumference not even or chiped
a. Grinding angle too small
b. Grinding pressure too high
4).Wheel swinging
a. Flanges mounted eccentrically
b. Spindle worn out
c. Wheel mounted not properly

* Cutting Wheels

1).Workpiece burned
a. Cutting time too long and power output too low
b. Wheel too hard
c. Cross section of work to be ground is larger than diameter of wheel
2).Worn out too quickly
a. Wheel too soft if cutting section appears white
b. Linear speed and R.P.M. too high
3).Cutting line not straight or broken
a. Workpiece fixed not properly
b. Cutting pressure too high
c. Flange diameter not proper
d. Operate not properly
4).Wheel rim torn
a. Operate not properly
b. Workpiece fiexed by spring
c. Cutting wheel works as depressed center one
5).Wheel cracked
a. Stator destroyed
b. Bearing problem
c. Wheel hole does not match with spindle
6).Hole destroyed
a. Set up not properly
b. Side grinding instead of straight cutting
c. Flanges broken
