In industry, ceramic balls are finished by concentric lapping and polishing with two plates placed face to face having matching concentric circular grooves on them, through several operations by gradually changing the load, plates and diamond grits sizes in the slurryMore Details
Abstract The finishing process of advanced ceramic balls can be divided into two steps. The first step is lapping in which most of the stock from the ball is removed at a higher material removal rate. The second step is polishing in which the required ball surface roughness, roundness, and dimensional and geometric accuracy are achievedMore Details

This paper treats the relation among lapping pressure, wear-distance-ratio, mesh number of abrasive sheet and sphericity of bails in the lapping circumstances of ceramic balls, and the new lapping method for ceramic balls are presentedMore Details
This system is effective on most materials including ceramic, graphite, ferrous metals, alloyed metals and stellite coatings. The Lapmaster Wolters LBVS has been developed to produce very accurate spherical surfaces on a variety of Ball Valves. A scratch free, matt high-quality surfaces is obtained on the Ball Valve and SeatMore Details
This research suggests that the lapping load for advanced ceramic balls in conventional concentric lapping could be doubled from 20N/ball to 40 N/ball without degrading the surface quality ofMore Details
The high-precision ceramic balls are machined by lapping usually, and the method of lapping has an important influence on the machining precision and efficiency of ceramic balls. In order to improve the precision and efficiency of ceramic ball machining, in the paper, a new cone lapping method is researched by the lapping experimentMore Details

After the ball is ground to approximate size, the ball is then lapped. This lapping process polishes the ball to the exact size required. This gives the ball a shiny finish. Click below to listen to the lapping process. Use Up/Down Arrow keys to increase or decrease volumeMore Details
In this study, a spiral V-groove plate method is employed in processing high-precision ceramic balls. After the kinematic analysis of the ball-spin angle and enveloped lapping trajectories, an experimental rig is constructed and experiments are conducted to confirm the feasibility of this methodMore Details
Jun 01, 2001 · The design of a novel eccentric lapping machine for finishing advanced ceramic balls is described. The kinematics of eccentric lapping is analysed and discussed, the symbolic expressions for the ball spin angular speed, ω c, ball spin angle, β, and ball circulation angular speed, ω c, are derived and numerical solutions are plotted. Two kinds of hot isostatically pressed (HIPed) silicon nitride ball …More Details
The Kemet Spherical Lapping Machine laps and polishes pre-machined spherical balls and cups to a mirror finish with the capability of achieving roundness better than below 3 microns. Features & Benefits: 6 motors all with independent variable speed to provide complete control. Size: …More Details

Mar 12, 2018 · The lapping experiments to reduce the sphericity error of shaped and unshaped ceramic balls after the full sintering to 1 μm were also carried out. It takes 55 h for the shaped blanks and 135 h for the unshaped blanks respectivelyMore Details
Aug 12, 2019 · Just as clay has a strong physical memory, one of my most vivid early memories of using pottery was eating ice cream from a heavily grogged stoneware bowl at my grandmother’s house, back in the 1980s. Having managed a well-known Australian pottery studio and gallery from the late 1950s to the 1970s, my grandmother, a painter herself, had an extremely large collection of works from numerousMore Details
