Affect the quality of the parts machined surface abrasion resistance
Machined surface quality processing contain dash appearance change shape and processing characteristics of the outer layer material. After the appearance of machined parts is not really aspiring lubricating face it there is not the same degree of roughness appearance, chilled, cracks and other appearance defects. Although only a very thin layer of a few microns to tens of microns, but are confusing influence the precision mechanical parts, wear resistance, co-precision, corrosion resistance and fatigue strength, and affect product performance and life expectancy, thus it is necessary to meet the focus.
What is the impact on the surface quality of machined parts wear is it?
On the one hand, machined surface roughness is too large and not too small to wear. The surface roughness is too large, the actual contact surface pressure increases, rough hump bite each other, seizing, cut off, so the wear and tear;
On the other hand, machining surface roughness is too small, it can lead to increased wear. Because the surface is too smooth, not keep lubricant between the contact surface is not easy to form a film, prone to molecular bonding and increased wear. The surface roughness of the optimum value and the work of the relevant parts of the machine, increase the load, the wear curves upward, move to the right, the best surface roughness also will be right.
