Wear is a situation that often occurs during
parts processing. What kind of wear will occur during general
parts processing?
First, Running-in wear is the wear of machinery under normal load, speed and lubrication conditions. This wear generally develops slowly and has little effect on processing quality in the short term.
Second, hard particle wear is caused by the abrasive particles falling from the part itself and the hard particles entering the machine tool from the outside mixed into the processing area, which are machined and ground, and the parts are destroyed, which has a serious impact on the processing quality.
Third, surface fatigue wear is caused by the machine under the action of alternating load, which produces tiny cracks and dot-shaped holes, and the parts are damaged. This kind of wear is usually closely related to factors such as pressure, load characteristics, part materials, and dimensions.
Fourth, the hot spirit is the effect produced during the friction process on the delivery, so that the
parts have the appetite of tempering fiery, scorching anxiousness and so on. Sex is great, accompanied by the nature of chance.
Fifth, corrosion fatigue is the activity of chemical action, that is, the activity of chemical corrosion. That is, the activity of chemical corrosion. Alkali and salt substances will be chemically corroded when they are in serious contact with acids, alkalis, salt substances, and the corroded surface combines with oxygen to form hard metal oxides that are easy to fall off, and they will be extremely tired.
Sixth, becoming younger is part of working under high temperature for a long time, part of the surface metal structure is heated, crystal clear, small gaps,
parts are fragile, wearability is reduced, and residual weakness.
