Tolerances

When asked the question "What tolerances can you hold" our response is usually "It depends", as there are a number of factors that can influence process capability on a given component or assembly. The information below is supplied as a guideline only. Should you have specific questions about our ability to adhere to tolerances on your project, we would encourage you to contact us for a more detailed technical discussion.

Machining:

Our customer's typically require +/-.005" on their drawings unless otherwise specified, however we see +/-.0005" on many of our customer drawings for key dimensions and critical characteristics.

Turning:

Chandler Industries routinely holds turned tolerances to +/-.0003" and occasionally +/-.0002" on a complete spectrum of materials, ranging from Aluminum to High Temp Alloys.

Milling:

Capabilities include holding milled positional tolerances to +/-.0005" and occasionally +/-.0002" on adjacent features, to +/-.001" on non-adjacent or Datum oriented features.

EDM:

Hole size, +/-.0005 or possibly better
Locations, +/-.0005
Profiles .0020

Precision Sheet Metal:

  • Flat Stock:
    • Tolerances up to +/- .005" on a flat sheet to sizes up to 36" x 36" (laser)
    • Tolerances up to +/- .010" on a flat sheet from sizes between 48" x 96" (laser)
    • Tolerances up to +/- .020" on sizes between 58” x 142” (turret)
  • Formed Components:
    • Tolerances up to +/- .005" from feature to feature where the features are on the same surface (without bends between feature)
    • Tolerances up to +/- .010" from feature to bend - isolated.
    • Tolerances up to +/- .010" from bend to bend - isolated.
    • Tolerances up to +/- .030" in cases where there are multiple bends and multiple features, example a formed box with flanges.
  • Multiple form parts using - Drilled in place or CNC:
    • Tolerances up to +/- .005" on anything less than 36" with CNC or drill fixture.
    • Tolerances up to +/- .010" on anything larger than 36" with CNC or drill fixture.
    • Note: Tighter tolerances can be achieved with secondary machining operations
