Known for performing ultra-precision CNC grinding operations, Groundim XI Precision Grinding was commissioned by a client from the robotics industry to grind four-hundred stainless steel spheres to meet very precise client specifications. Using a silicon carbide grinding wheel, we were able to uphold a tight overall tolerance of (±) .0002 of an inch for both the faces and inner diameter of the parts. We also maintained .0002 of an inch circular runout, with a perpendicularity tolerance of .0002 of an inch and a profile and symmetry tolerance of .0002 of an inch.
Constructed from stainless steel, the spheres were ground to meet exact client dimensional requirements. After grinding was complete, the spheres measured precisely 1.500 inches in diameter, with an outer diameter measuring 1.500 inches and an inner diameter measuring 1.1811 inches. The sphere also measured exactly 0.700 of an inch in length with a .319 of an inch wall thickness.
In addition to our client's dimensional specifications, our customer also requested that the spheres be provided with an ultra-smooth, mirror-like surface. We attained this by polishing each sphere, endowing these parts with a 4RA finish. We also ensured that all stainless steel spheres maintained a Rockwell hardness rating of 60-65.
After guaranteeing that every one of our client's specific product requirements were met, we then delivered all four-hundred stainless steel spheres directly to our customer's facility located in Manteca, California. Our ultra-precision grinding operations exceeded our client's expectations for quality. |
