Grinding Wheels

Electroplated Diamond grinding wheels:  Mainly used for machining nonmetallic materials with high rigidity like ceramics, glass, tungsten carbide, ferrite and so on
Electroplated CBN grinding wheels:Mainly used for machining metallic material such as chilled cast iron, founded alloy steel, titanium alloy and so on

Diamond and CBN (cubic boron nitride) internal grinding wheel produced by moresuperhard’s factory can achieve a small diameter of 1.5 mm, and the wear resistance is very good, and there is no need to frequently trim the outer circle. Batch processing of small holes of parts can ensure the consistency of roundness, perpendicularity and diameter tolerance accuracy, high temperature resistance during the grinding operation, and no burns on the workpiece and the grinding wheel.
Grease grinding fluid must be added during the grinding process To cool down and remove chips (tap water can not be added directly, tap water will carbonize the high-temperature grinding CBN raw materials), to avoid the large amount of metal scrap generated during the grinding process from squeezing the hole wall of the workpiece and blocking the pores on the surface of the cubic boron nitride grinding head .

CBN internal grinding wheel produced by moresuperhard has specifications ranging from outer diameter φ2.5 to φ75, aperture diameter φ1 to φ25, and the height can be made according to customer’s special requirements.
The processing cost of a single part is 30%-50% lower than that of imported grinding wheels.
CBN Internal cylindrical wheels are widely used in the bearing industry, sewing accessories industry, compressor industry, mold industry, pump industry and auto parts industry (hydraulic tappets, constant velocity joints, cylinders, fuel injectors, gears). Good results have been achieved in various internal grinders, coordinate grinders, and inner surface grinders.

2. Steel parts: 20Cr, GCr15, Scr415H, 45 steel, 55 steel, etc
The vitrified CBN (cubic boron nitride) internal grinding wheel produced by our factory can achieve a small diameter of 1.5 mm, and the wear resistance is very good

Vitrified cbn wheels are suitable for internal grinding vane pump, rotary vane compressor stator inner circle and curved surface, piston refrigeration compressor cylinder, universal joint ball path, industrial bearing inner circle or inner hole, Fuel pump nozzle etc.
The vitrified bond cbn grinding wheel can be easily dressed with ordinary diamond tools. Due to the high hardness of cbn abrasive grains, the diamond wears quickly during dressing.

Vitrified cbn internal grinding wheels are mainly used for internal grinding of compressor parts, internal grinding of bearings, constant velocity universal joint ball cage and internal and external ball path grinding, etc.

What are the characteristics of resin diamond grinding wheels?
Resin bond is an organic bond. The resin diamond grinding wheel manufactured by this bond has high strength, certain elasticity, low heat resistance, good self-sharpening, simple production, and short process cycle. It can manufacture grinding wheels with working speed higher than 50 m/s and very thin grinding wheels.
