Special-use Grinding-stone for thin-cutter Slitter-Scorer machine in Corrugated carton production line include special wheels for hard-alloy blade, high-speed steel blade and Grinding-stone for blades in miscellaneous materials. "Yinglong" Grinding-stones pocess the following characteristics: 1, We adopt the ultra-hard abrasive materials of Synthetic Diamond and CBN (Cubic Boron Nitride), which can almost satisfy all the thin-cutter blade in the materials of high-speed steel and hard-alloy (Sintered-carbide YG8). 2, Using the Resinoid Binder for Grinding-stone which is the most suitable to the working of blade. Keep the excellent grinding-capability at any time. 3, Adopt of different granularity suit to the grinding under different materials and situations. Coarse grinding choose 80#-?120#，half-coarse grinding choose 120#?180#, fine grinding choose 180#--W40, polishing choose W40--W0.5. The Tungsten steel blade own high glabrous and high requirements to the precision of blade-grinding, it suits to choose among 180#--240#. High-speed steel should choose among 100#--150#. 4, Reasonable collaboration of Grinding-stone in different density will be optimic to the different blades in different materials, as well as merits of high-precision, excellent cooling etc.
