Production Grinding of Cold Headed and Screw Machine Parts
 |
Ever Ready uses its grinding expertise in several ways to serve customers in addition to producing pins, punches and other steel tooling. Centerless grinding is one of several secondary operations performed on cold headed and screw machine parts. Centerless grinding is capable of providing close tolerance outer diameters, undercut diameters, flat surfaces, and precise multiple steps, angles, and/or radii. The most commonly performed operation at Ever Ready Pin is the precision grinding of shoulders, bodies, and grips on cold headed special parts and a wide variety of screw machine parts. |

Production quantities range from 1 to 1,000,000 pieces in sizes from .012 to 4-1/2" in diameter. Many high volume orders are run on automatically fed equipment. Tolerances within .0001 inches and finishers within 6 micro-inches can be provided.
A method of producing flats on the outside diameter of parts using centerless grinding equipment is much less expensive and more consistent than broaching or milling and lends itself well on threaded parts.
