Cutting wheel must be carefully checked

Cutting wheels must be carefully checked and identification prior to installation. To check the identification of:
1. Check the wheel grade is correct, it meets all the selection grinding wheel performance, shape and size.
2. Check the appearance of the structure and differential wheel situation. With the eye whether the appearance of damaged wheel (or cracks). The appearance of damage (or crack) the wheel can not be used. Another requirement wheel ends flat surface, no obvious skew.
3. Check the grinding wheel and differential internal cracks. By hand and wheel, grinding wheel with a wooden hammer tapping hear its sound, no crack crackled wheel, the wheel is cracked hoarse voice, which can not be used.

High strength cutting wheel

Resin binder is an organic binder, this binder manufactured high cutting wheels strength, has a certain flexibility, low heat resistance, good self-sharpening, easy to manufacture, process cycle is short. Work can be produced faster than 50 m / s wheel and thin wheel. Its scope of application after the vitrified widely used rough grinding, snagging, cutting and grinding freedoms, such as grinding steel ingot casting deburring and the like. Can manufacture high-speed, high-quality finish grinding wheels, heavy duty, cutting and grinding wheels of various special requirements.

Granite cutting disc wear problems

Any granite cutting disc has its requirements for the use of certain wear, the wear reaches a certain level it is necessary to replace the new disc. Not in order to save material, it requires the use of ultra-wear, which is a very unsafe violations. A general rule, when the cutting discs wear to chuck diameter larger than the diameter of 10mm it should be replaced with a new disc. Validity of the problem from the Treasury brought a new disc is not necessarily qualified disc, new disc even buy from the manufacturers are not necessarily qualified disc. Any disc has its certain expiration date, in the effective use of the term, it is qualified disc; use over the period, it is not necessarily qualified disc.

Cutting wheel design

Grinding wheels designs should be considered in addition to grains, it must also consider the diamond / CBN cutting discs and SiC / Al2O3 cut difference between the sheets. Due to high grain hardness and fixed with a durable adhesive abrasive, diamond cutting wheel CBN / performance is very durable. Metal disc periphery (continuous rim) just stick a thin layer of abrasive. These are long-term consumable cutting wheel cutting disc. SiC and Al2O3, and other abrasive, wear relatively fast, relatively inexpensive. Thus, the entire body of the abrasive grinding wheel and a binder. This cutting wheel is called the consumable cutting disc.

Select grinding wheel wheel

According to the material to be cut, you may need to use a grinding wheel with different ingredients. Grinding wheel is also affected by the choice of material hardness and toughness. Split carbide ceramic or diamond bonding material need to use adhesive made from metal or Bakelite cut plate.
Bakelite adhesive bonding using aluminum oxide (Al2O3) grinding wheel is a typical choice cut of ferrous materials. Cubic boron nitride (CBN) is also increasingly used in high hardness cutting ferrous materials. Non-ferrous metal grinding should be chosen by the phenolic adhesive bonding of silicon carbide (SIC) grinding wheel.
