to prevent the circular blade hardness is low and how to make the circular blade wear durability

Let's say the first choice, how to make circular blade hardness to achieve the best state, is a circular blade hardness and toughness to achieve the perfect value!
(A) heat treatment process in strict accordance with operating procedures, frequently check the gun temperature heat treatment equipment and instruments, such as the working status.
(2) In the quenching apparatus, the cooling medium is loaded in the circulation or agitation, to improve the cooling capacity of the quenching medium and uniformity.
 (3) on carbon tool steel and alloy tool steel circular blade, always check its hardness after quenching. Pair of high-speed steel circular blade, always check its quenched microstructure.
(4) Set monitor temperature control to prevent tempering temperature (temperature tempering run).
(5) to ensure the circular blade (including the blade) performance under the premise, according to the circular blade structure and size selection with the proper hardenability of steel.
(6) strict control of the chemical composition of  drill bits the steel and the original organization, plus 9 Steel management to prevent steel mixing.
(7) strictly in accordance with specifications for grinding circular blade grinding
  Two: how to use the circular blade will wear durability
    1, the selection of materials.
Choice of materials is an important step, the selected material is aligned with the customer cut and abrasion resistance of materials use the appropriate materials, materials selected is not good, a direct impact on the use of blade life.
2, the casting process
Air hammer steel casting eliminate occurred during a workout loose and vague and other shortcomings, the usefulness of ceramic tile saw  forging raw data is to make more solid circular blade.
3, the heat treatment process
Heat treatment process is a very important quality in production order, the customer and swap chipping mentioned port is the primary reason that the heat treatment. Effect of heat treatment of the circular blade material promoted higher hardness.
4, the machine processing steps
Based on customer requirements, we use cutting discs  sophisticated tools to right circular blade material thickness, parallelism, flatness, cylindrical, inner circle such as to make the product. Thickness Gongyi guarantee within the ± 0.0005mm. View product of all precision in temperature indoors.
