Manual dressing of the grinding wheel is another important factor in producing satisfactory work on your crankshaft grinder The wheel must be dressed each time it is placed on the machine, even though it may not have been removed from the wheel center Mount the wheel dresser on the grinder tableTurn the diamond 1/4 turn every fifth dressing Use faster traverse and deeper penetration The grinding operator should try using more infeed, this should help deter wheel glazing PROBLEM: Fine Troubleshooting Common Crank Grinding Problems
Grinding Machines that involve the usage of crankshaft grinding wheels are generally run at a very high speed of 2700m/min; however, some production machines can run at higher speeds as well The thickness of The main reason crankshaft grinding is done is because the crank wears over time Over thousands miles the end play between the crankshaft and the bearings increases When the “fit” between the bearings and the crank isn’t perfect it lowers oil pressure and decreases lubricity The less oil to the crank the faster it can wear outWhat is Crankshaft Grinding?

During the dressing process, a rounded diamond will roll some of the severed wheel back into its pores This causes the wheel to become loaded, even before grinding Also, check your coolant to make sure it’s not too concentrated And, be sure to change dirty coolant PROBLEM: Wheel glazingeffects on grinding wheel performance can result in optimal precision grinding operations Overlap ratio is specifically used when truing and dressing using rotary or stationary dressing tools in a traverse dress mode Overlap ratio is not used in plunge dressing applications Precision grinding processes are required to manufactureEFFECT OF DRESSING OVERLAP RATIO ON THE GRINDING
The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec and can be calculated using the following equation: Speed ratio = V r ÷ V s The dress speed ratio can be a positive or a negative value as shown in Figure 5For more than 60 years, Molemab has been designing and manufacturing innovative and quality grinding wheels and abrasives Today Molemab distributes its products worldwide through a solid network of production units, technicalcommercial branches and exclusive distributors, confirming itself as a modern industrial realityMolemab Spa Grinding Wheels, Cutting discs and diamond tools
