FAQ
1. Which grinding wheel do you use for crankshaft grinding?
You typically use vitrified bonded grinding wheels for crankshaft grinding because they maintain wheel shape, resist thermal deformation, and deliver stable performance in both rough and finish grinding operations.
2. Which abrasive works best for crankshaft grinding?
You should select the abrasive based on the crankshaft material:
White Aluminum Oxide (WA/A) 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.
