Crankshaft Grinding Wheel
Product Description
A crankshaft grinding wheel is a specialized grinding wheel used for precision machining and reconditioning of crankshafts.
Crankshaft grinding wheels are widely used for precision grinding of crankshaft journals, crankpins, and main bearing surfaces in engine rebuilding, repair, and manufacturing applications. They are suitable for grinding automotive, truck, marine, and diesel engine crankshafts, helping achieve accurate dimensions and a consistent surface finish.
They are typically manufactured with a vitrified bond to provide high rigidity, good form retention, and effective heat dissipation during grinding.

Abrasive Options for Crankshaft Grinding
| Abrasive | Typical Application |
|---|---|
| Brown Aluminum Oxide (A) | Steel and alloy steel crankshafts |
| White Aluminum Oxide (WA) | Precision grinding and finer surface finish |
| Pink Aluminum Oxide (PA) | Precision grinding of suitable alloy steel |
| Ceramic Aluminum Oxide (SG) | High-efficiency grinding and higher stock removal |
| Silicon Carbide (C/GC) | Suitable cast iron grinding applications |
Grit and Hardness Selection
Grit size affects material removal and surface finish during crankshaft grinding.
| Grit | Typical Application |
|---|---|
| 36–46# | Rough grinding and higher stock removal |
| 60# | Semi-finish grinding |
| 80# and finer | Finish grinding and finer surface requirements |
Hardness can be customized according to the crankshaft material, grinding conditions, coolant, machine and dressing method.
The suitable grit and hardness depend on the actual grinding application. We can recommend a suitable specification based on your existing wheel or machine requirements.

FAQ
1. What type of grinding wheel is used for crankshaft griniding?
Vitrified bonded grinding wheels are widely used for crankshaft grinding because they provide good rigidity, form retention, and dressing performance. The appropriate wheel specification depends on the crankshaft material, grinding machine, and grinding operation.
2. Which abrasive works best for crankshaft grinding?
You should select the abrasive based on the crankshaft material:
White Aluminum Oxide (WA) works best for alloy steel and forged steel crankshafts
Green Silicon Carbide (GC) performs well on cast iron crankshafts
The correct abrasive reduces wheel wear and minimizes grinding burn.
3. What grit size should you choose for crankshaft grinding wheels?
You commonly choose:
36–46 grit for rough grinding and high stock removal
60 grit for semi-finish grinding
80 grit for finish grinding when you need a finer surface finish
Your final choice depends on material hardness and surface quality requirements.
4. What sizes do the crankshaft grinding wheels come in?
Manufacturers commonly supply outer diameters of Ø750, Ø800, Ø900, Ø915, and Ø1000 mm.
You can also customize wheel thickness and bore size (such as 304.8 mm) to match your grinding machine.
5. What causes grinding burn during crankshaft grinding?
Grinding burn occurs when you use an incorrect wheel specification, apply excessive infeed, supply insufficient coolant, or neglect proper dressing.
You can significantly reduce burn risk by selecting the correct grit size, vitrified bond, and dressing method.
