ABRASIVE TOOLS RECOMMENDATIONS
OF CHOOSING AND APPLYING


CHOOSING THE RIGHT ABRASIVE MATERIAL

  • 14A (A)      Processing of materials with high rupture strength, snagging of steel castings, rolled stock, high-strength cast iron, processing of carbon and alloyed steel, bronze, nickel and aluminum alloys.

  • 25A (WA)   Processing of the hardened details of carbon, high-speed and stainless steel. Processing of the fine details and tools (teeth, knives, drills, chisels), sharpening.

  • 38A (ZK)     Power grinding of steel work pieces by snagging.

  • 54C; 63C (C; GC)    Processing of hard materials with low rupture strength (cast iron, bronze, brass, hard alloy, glass, precious stones, marble, granite, porcelain), and very tenacious materials (high-temperature steel, alloys, copper, aluminium)

CHOOSING THE WHEEL GRIT

  • F10 - F22 (200 - 80)    Snagging operations with a large cutting depth, billet and casting grinding. Treatment of materials, causing loading of wheel's surface (brass, copper, aluminum)

  • F22 - F36 (80 - 50)    Surface grinding with the wheel face, chisel sharpening, abrasive tool dressing, cutting off.

  • F30 - F60  (63 - 25)     Preliminary and combined grinding, cutting tool sharpening.

  • F40 - F220  (40 - 5)   Flat surface grinding.

  • F54 - F90  (32 - 16)    Fine grinding, profile surface processing, small tool sharpening, grinding of brittle materials.

  • F100 - F180  (12 - 6)   Finish grinding, lapping of cutting tools and steel billets, thin edge sharpening, preliminary honing.

  • F180 - F280  (6 - М50)    Finish grinding of metals, glass, marble and etc., thread grinding finish honing.

  • F230 - F600  (М63 - М14)    Superfinishing, finish honing, thin edge lapping, thread grinding of pieces with a fine pitch, polishing.

GRIT CHOICE DEPENDING ON THE SURFACE ROUGHNESS

CHOOSING THE TOOL HARDNESS
  • W, T  (ЧТ, ВТ)   Snagging operations, abrasive tool setting, ball-bearing ball grinding.

  • S, R, Q, P  (Т2, Т1, СТ3, СТ2)   Cutting off, slotting, hand snagging operations, circular external grinding, centreless grinding, uneven surface and profile grinding.

  • P, O, N  (СТ2; СТ1; С2)   Preliminary circular external and centreless grinding of steel, malleable cast iron. Profile grinding, uneven surface processing, honing and thread grinding of parts with a coarse pitch.

  • O, N, M  (СТ1 ;С2; С1)   Flat surface grinding with the segments and annular wheels, thread grinding with the resinoid bond wheels.

  • N, M, L, K  (С2; С1; СМ2; СМ1)   Fine and combined circular, external centreless and internal grinding of steel, flat surface grinding, thread grinding, cutting tools sharpening.

  • L, K, J  (CM2, CM1, M3)   Sharpening and lapping of hard-faced cutting tools, grinding of special-property alloys, which are hard to process, polishing.
