Read on to learn more about steps that should be considered best practices for precision ball manufacturing to ensure utmost quality. ### Steps in the Precision Ball Manufacturing Process 1. Raw materials are inspected. 2. Cold heading machine - cuts off proper length of the wire material, then forms the cylindrical shape into a roughly spherical shape 3. Flashing - removes any excess material on the perimeter of the balls 4. Heat treatment - quench and temper process to decrease internal stresses 5. Grinding - before and after heat treatment, to bring the ball closer to its final requirements 6. Lapping - two phenolic plates a very fine abrasive flurry, such as diamond dust, to further decrease surface roughness 7. Cleaning - removes any processing fluids and residual abrasive materials leftover from the manufacturing process 8. Visual inspection - Every lot is inspected by hand to check for defects and dirt. 9. Roller gauging - balls are sorted by largest to smallest by the roller gauge. Oversized and undersized balls are eliminated.  10. Quality control - Each lot is tested for hardness, diameter, roundness, and surface roughness 11. Packaging - Balls are packed dry in plastic bags. If the materials are prone to oxidation, vapor corrosion inhibitor paper is included. Hartford Technologies ensures utmost quality through our rigorous manufacturing and inspection process.
