(1) Casting bush to bush before the full warm-up, the tile body of water completely evaporated (especially in re-casting of the old tile when should note that the residual cavity to prevent the bearing cooling water) to prevent the casting time liquid Babbitt "frying pan" wounding.
(2) fully warmed up, use the electric wire wheel to tile cleaned surface oxide film (technically demanding, but also in tile hanging tin), to ensure that the tile liner and a solid cast iron tile adhesive surface to avoid shelling.
(3) After casting bearing, bearing in check after no cracks and blisters, but also for the pressure test, check for water leakage, if any, must be welded back together, until there is no leakage point is reached. Otherwise in use, bearing cooling water will leak into the main mill bearing lubricant, the lubricant deterioration, affecting the normal operation of bearing.
(4) With up truck bearing blank, we should strictly control the amount of feed and table speed, prevent excessive cutting heat, so that tile blue or yellow, leading to tile surface hardened.
(5) bearing a good tank, it should be in the corresponding hollow shaft journal (this point is important because one correspondence bearing and hollow shaft is optional) on a good coating of oil and red lead powder, and bearing deduction on the ground in the hollow shaft journal, according to the distribution of contact points necessary scraping until the tile in the tile of the contact surface near the centerline and the point of contact until evenly distributed, can not help there folders tile mouth, bottom contact and the diagonally contacts and so on.
(6) The hollow space between the journal and the bearing control technology is within the requirements of the quality of bearing scraping the basic guarantee.
