Vitrified CBN Grinding Wheel for Crankshaft

Description of cbn grinding wheel for crankshaft
A crankshaft is made up of Main bearings, Pin bearings and Crank webs. A completely smooth journal is essential for motor efficiency during piston ignition of an engine.

Vitrified CBN grinding wheel are remarkable for preventing grinding burns to the shoulder of the Crankshaft. CBN Grinding Wheel For Crankshaft can equip with various high precision CNC Crankshaft Grinding Machines, Suitable for high efficient,heavy grinding of Crankshaft pin grinding,Journal grinding.The wheel speed is generally 80m/s-120m/s.

Solutions for Crankshaft Grinding
Moresuperhard can provide vitrified CBN grinding wheel and vitrified aluminium oxide grinding wheel,  Electroplated CBN Wheel for rough,semi-finish and finishc  grinding crankshaft.
A type of innovation with the grinding wheels, the crankshaft grinding wheels finds its usage in the different automotive, truck, diesel, aircraft, and small engine manufacturing industry and also in the various engine rebuilding firms that are used to regrind the pins and the bearings.

– Main Bearing and Crankpin Journals Grinding with vitrified CBN grinding wheel
Cubic boron nitride (CBN) grinding wheels are used for high production machining of automobile crankshafts.

– Main Bearing Grinding with Vitrified Aluminum Oxide Wheel
When producing small lots or machining larger crankshafts (for trucks and ships), grinding wheels with aluminium oxide abrasives are used.
Benefits of Moresuperhard Vitrified Aluminum Oxide Wheel
-The evenness of hardness and balance performance of the wheels are 30-50% higher than that of China State Standard.
– The thickness deviation of a group of the wheels is not more than 0.2mm.
– The parallel tolerance of two ends is not more than 0.1mm.

Rough Grinding Main Bearing and Crankpin with Electroplated CBN Wheel
A pin chasing process with electroplated CBN wheels is used for the roughing of the main and in particular the pin bearings of a crankshaft.

Finish Grinding FLANGE and POST GRINDING
Finish grinding with vitrified bonded aluminium oxide or vitrified cbn wheels.During cylindrical grinding operations for the flange and post it is possible to use different specifications depending on the requirements of the respective contact zones.

Dressing and truing of crankshaft grinding wheels
The dressing and the truing of the grinding wheels: This is mainly done in order to restore the original cutting geometry and to make a final product which is flatter and round. The grinding wheels get their flatness and roundness from the dressing and truing of the grinding wheels.
