Frequent problems during grinding – grindaix GmbH
The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part Grinding burn occurs when too much heat is channelled into the part Microcracks and brittle surfaces are often the result The occurrence of grinding burn depends on a number of factors and the interactions thereof Grinding burn is probably one of the most common problems with grinding machines Burns on the rim zone of the parts will cause tiny microcracks and a brittle surface Grinding parts cause a high level of heat because of the amount of frictionKeep Calm and Grind On: Solving Common Grinding Wheel Grinding problems show up in two ways: in the appearance of the workpiece and as cost or productivity issues After verifying that the grinding machine isn’t at fault, attention should turn to the grinding wheel Appearance problems divide into poor surface finish, chatter, and burningTips To Solving WheelRelated Grinding Problems The grinding head of the internal grinding machine is prone to heat and inflexible rotation or even stuck (internal grinding problems) This problem is mainly because impurities and small sand particles enter the oil injection hole or the bearing2019 Tips To Solving the Internal Grinding Problems Dress regulating wheel at the same angle as dressing grinding wheel (in order to prevent bent caused by uneven grinding force) Dress wheel to ensure that it has slight gradient upward to exit side Spirals: Incorrect wheel dressing: Dress wheel so it stops grinding 1/2 from exit edge Round off both edges of wheel Guides improperly adjustedGrinding Wheel Use Precautions Fault Finding and
