subject: Seiko introduced to improve fretting wear properties of the machine tool table [print this page] A steel ball and ceramic ball ball, oil has "NSKGREASEAS2" and "NSKGREASENF2", these were combined for comparison. Specifically, Ball and lubricants were used (1) steel ball and "NSKGREASELR3"; (2) steel ball and "NSKGREASENF2"; (3) ceramic ball, and "NSKGREASELR3". Here the lubricant "NSKGREASENF2" using a low-viscosity base oil, thickener, and good flow properties with high resistance to wear additives, anti-wear performance than "NSKGREASELR3" high. For these three kinds of circumstances, in the rotation speed of 0.6min-1, stroke 0.02mm, swing angle of 0.45 , swing time of 400 hours (3,000,000 cycles), swing under the conditions of test, the results show that the standard specifications ( 1) occurred in 2 ~ 3 m fretting wear and tear, (2) loss of less than fretting 1 m, and (3) that the loss of almost no micro. Namely fretting wear prevention, (2) and (3) ideal. Certainly, cost (3) Max. Embossing process are used for home appliances and automotive interior components such as molding resin used for the surface area in the hope that the original etching and sandblasting on the machining process to mold a loud voice for direct etching. If the improved machine tool table fretting wear resistance, can meet these needs, develop new areas of embossing process.
