Grinding common defects cause analysis
Burns: the amount of feed is too large, insufficient coolant, wheel size is too thin, too hard binder, high grinding zone temperature caused.
The clogging not sharp: abrasive improper selection, improper choice of binder, the particle size is too fine grinding wheel blunt.
Chatter marks: spindle wear, the grinding wheel clamping is not tight, the grinding wheel is too hard, too fine granularity, the feed rate is too large, the cutting wheel beating Organization uneven grinding wheel imbalance.
4. Scratches: large grain abrasive grinding wheel soft.
Wheel consumption: feed too, lack of coolant, improper selection of abrasives, binders, binder organization is too loose, wet grinding wheel for dry grinding, the grinding wheel is too soft caused.
