122 行· These tools consist of a precise brass ball with a layer of charged into the surface. The brass ball is usually attached to a steel stem to provide a holding dev. In use, the charged brass is slowly rotated under very light pressure against the ball seat to provide a perfectly spherical narrow land, forming a high quality seal.
16/02/2016· You might try a CBN charged ball lap. Running it driven with an eccentric pin to drive it will improve wear rate and form retention. Alternatively try using the silicon nitride ball for tooling pressing it into the cone to form the seat. The silicon nitride is incredibly strong in compression, exceeding 400,000 psi compressive stress.
ball seat lapping tools A better solution is to use our spherical balllapping tools. They have a heavy concentration of particles embedded in their surface. These embedded lapping balls are usually glued in a shallow conical cup on the end of a cylindrical pin, to facilitate driving it in the seat
