Superabrasive grinding wheel is widely used in the field of automotive parts processing. CBN grinding wheel can be used for grinding crankshaft, camshaft, engine value, hydraulic tappet, rotor slot, bearing, cylinder and other materials.

These materials mainly include cast iron (such as chilled cast iron, ductile iron, gray iron, alloy cast iron, etc.) and steel parts (such as 20Cr, GCr15, CF53, 45 steel, 55 steel, 80B high carbon steel, etc.).

Crankshaft Grinding

We can provide vitrified CBN wheel or electroplated CBN wheel for rough, semi-finish, finish grinding crankshaft.

1A1 grinding wheel is often used for crankshaft.

Camshaft Grinding

This grinding mode belongs to high-speed grinding and requires high precision of the grinding wheel.

1A1 vitrified and electroplated CBN wheel is used for camshaft grinding.

Fuel Injector Grinding

The grinding mode is mostly internal grinding. Small diameter vitrified CBN wheel is used for internal grinding.

Gear Hobs Grinding

The gear hob is made of HSS material and is ground with the single bevel CBN grinding wheel. It is suitable metal bond and resin bond. The cylindrical of the single bevel grinding wheel is relatively thin, and when end face grinding, it can be ground to the bottom of the edge.

Vitrified CBN Wheel For Cleaning Shaft End

1A9 vitrified bond CBN wheel is used for cleaning the shaft end of automobile.

Rotor Slot Grinding

Vitrified bond CBN flute grinding wheel is suitable for rotary vane compressor, steering pump, vane pump rotor groove grinding, transmission shaft grooving and other industries and after groove molding grinding.

14A1 vitrified bond CBN grinding wheel is used.

Engine Valve Grinding

There are many stages in engine valve grinding, mainly including valve cut off grinding, valve shaft centerless grinding, valve head and valve seat grinding, valve groove and tip radius grinding, valve stem end face grinding, valve seat grinding and etc. Resin /electroplated /vitrified / metal bond CBN grinding wheel is used.

Cylinder Honing

Diamond/CBN honing stick for cylinder honing depending on the material of the cylinder body. Metal bond honing stick has long life, while resin bond honing stick has better surface roughness.

Automobile Bearing Grinding

Bearing grinding includes outer ring and inner ring, roller end face, centerless, raceway, internal grinding, diamond roller dressing, and etc. Resin/ vitrified/ metal/ electroplated bond are used. Both ceterless and double sided grinding modes are required.

In the grinding process of automotive parts, various grinding modes are applied. CBN grinding wheel is main type, and the usage of bonding agent rest upon the actual situations.
