Plane-parallel functional surfaces on workpieces are generated most efficiently with the double disc surface grinding process. I.e. two parallel surfaces are machined simultaneously by two grinding wheels arranged in a set. Typical examples include roller bearing rings, piston rings, shims and seals, spacer plates, connecting rods, as well as blades and shearing plates.

The surface lay generated by grinding would cause abrasion to the bearing surfaces if left unpolished. By polishing in the direction shown in either the figure 3 or 4, the surface lay is reversed by the polishing operation removing fuzz created by grinding and leaving a surface lay which will not abrade the bearing surface.

28.06.2010 · My 1929 B&S surface grinder had the original split bronze bearings when I bought it. After my thorough rebuild, I quickly found that I could not get a decent finish on a part. So I found a used Parker Majestic cartridge spindle (motor and spindle is one long unit with no belts) made for a later model B&S No. 2 for $100. I figured out a way to bore a hole through the antique B&S head and slip ...

Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough surfaces usually require abrasive grit sizes in the range of 120-180 grit [P120 ...

One grinding spindle ensures precise taper and plane surfaces (Z/X1), another takes care of the shoulder (Z/X2), while the last spindle grinds the internal diameter and shoulder (Z/X3). Further advantages include the redevelopment of the gearwheel grinding, which is based on the use of a perfect workpiece support. This is achieved through the center clamp, consisting of hydrostatic bearing and ...

bearing surfaces of meshing gear sets can be fully optimized, and therefore, the forces acting on the bearing surfaces can be ideally distributed. This leads to more efficient gears, both in terms of power density and fuel consumption. Today, in terms of grinding times, twist control grinding is on par with the standard continuous generating grinding which is well-established in the industry ...
