Fig. 9 (a) and (b) show the form accuracy PV of 0.21 wave measured with the laser interferometer and the surface roughness R a …
— If you look at my video above, standard lapidary equipment is used to make marble size spheres. The grind is inside a hollowed out SiC grinder wheel and the pre-polish is using granite pades cut to fit inside of appropriately sized pipe fittings. A friend at my class claims as many as 10 per hour can be made of 3/4" size agate cubes.

Rob Cosman 8 Inch CBN grinding wheel Self-Aligning Spherical Waher Setis AWESOME for your sharpening needs! ... The Spherical Washers act as a ball and socket to compensate for slight misalignment and to eliminate undue stress from the shaft nut. The hole size on this ball and socket set is slightly larger for efficient equalizing action.
— The axiomatic principle is that a cylinder can sit on a spherical surface and make line contact all round its perifery. So even though your workpiece is tiny, some sort …
— The robotic belt grinding system includes a robot motion unit (ABB IRB4400-60/1.96), a force control unit (ATI Omega 160) and an abrasive belt grinder unit. During the material removal process, the robot holds the workpiece in contact with the rotating contact wheel of the grinder and feeds it slowly, which follows the predetermined off-line path.
Ken Rizza of WoodTurners Wonders has spherical washers for mounting a CBN wheel to a bench grinder but not for a 1" arbor. I found one (link below) with a 1/16" oversize on the …

— Submicron-sized quasi-spherical zinc oxide (ZnO) particles were prepared by wet ultrafine grinding in a stirred media mill under various conditions. The effects of parameters (i.e., solution type, acid or alkali concentration, solid content and grinding time) on the particle median size (d50), particle size distribution (PSD) and sphericity of ZnO …

— Hi, I recently ordered a 2000W 48V DC Brushless Motor & Controller Kit from Vevor. Motor model : MY1020D Controller model : BY15WF02-A The kit went together fairly easily, all the wires went together by color and it went in reverse, researched it might be a hall/phase combo, messed around a bit and switched the hall sensors on the motor …
— When the wheel axis space intersects the workpiece axis, as shown in Figure 4, the pose and position of the wheel have five degrees of freedom: (z, α,, d, θ), where z is the distance translated along the Z-axis, α is the rotation around the Y-axis, is the rotation around the Z-axis, and d is the distance from the center point of the grinding …
