 Diamond honing stones, honing heads, honing sticks are used for fine grinding cylinder, hydraulic cylinder, air compressor cylinder, cylinder liner, valve hole, oil nozzle pump, refrigerator compressor, seamless tube, diesel, motorcycle, tractor engine, pump body, cylinder bore of hydraulic cylinder, cylinder liner and the inner surface of the other cylindrical through-hole.

CBN internal grinding wheel processing hardened steel's advantages:
(1) High hardness, high temperature red hardness, specifically for high hardness difficult to machine materials.
(2) High temperature resistance and good thermal conductivity.
(3) Strong wear resistance and good impact toughness.
(4) High processing accuracy.

Moresuperhard's Internal Grinding Wheels are used in internal and external faces of ball & roller bearings, rings, cylinders, barrels, small cylinder, compressor parts, injection nozzle parts, gear parts, connecting rod ends in the automobile industryetc, gun barrels, gear bores, hydraulic and pneumatic cylinders etc.

Because the high temperature strength of superalloy is high, the work hardening is serious, and the superalloy contains many hard points composed of metal carbide, nitride, boride and intermetallic compounds, especially the micro particles composed of phase, so the mechanical friction and wear is serious.  Not only that, because of the cutting force, high cutting temperature, under high temperature and high pressure, a chip interface bonding, resulting in bonding wear.  In addition, at a higher cutting temperature, the diffusion of some alloying elements (such as tungsten, cobalt, titanium, niobium, etc.) in the material with the upper part and chip is intensified, resulting in diffusion wear.  At the same time, under the condition of high temperature, carbon, hydrogen, oxygen, nitrogen and other elements in the surrounding medium are easy to immerse into the cutting interface, resulting in the formation of the corresponding brittle phase of the material, increasing the stress concentration of the surface tissue of the material, resulting in cracks, and even edge collapse.  In the process of grinding superalloy, the abrasive grains of grinding wheel not only have serious wear but also have serious adhesion blockage.
