Precision Jig & Thread Grinding Services
Nation Grinding, Inc. leverages its close to six decades of industry experience to precision jig and thread grind parts such as ball, injection and timing screws as well as worms for machinery, mold grinding and tooling/fixture applications. Our client focus targets the aerospace, automotive, marine, medical, military, mining, pulp and paper, spindle and wire industries.
Our processes include polishing and sharpening as well as forming, tapering, angling and radius. We deal with ACME and metric threads as well as a wide range of metals, composites, ceramics and more unusual materials such as sapphire, granite and wood. We can handle part lengths of up to 110″ (2794mm), roundness of .0001″ (.0025mm), concentricity of up to .0001″ (.0025mm) and tolerances to ± .0001″ (.0025mm). We also provide a range of repair services on everything from the inside and outside diameter repair of shafts, chrome plating and spindle repair and more. Our additional services include CAM, quality control reports, reverse engineering and spindle grinding, with a focus on quality control inspections that use a variety of technologies to confirm our superior quality and compliance with standards such as ISO and Mil-Spec. In most instances, we can work with a lead time of 5 to 10 working days on prototype or large-scale production runs.
