Tolerances

Precision Tolerance Capabilities

When asked “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 encourage you to contact us for a more detailed technical discussion.

Machining

Our customers 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

Precision Sheet Metal

Flat Stock

• Tolerances up to ±.005″ on flat sheet to sizes up to 36″ x 36″ (laser)

• Tolerances up to ±.010″ on 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″ feature to feature on same surface (without bends between)

• Tolerances up to ±.010″ from feature to bend (isolated)

• Tolerances up to ±.010″ from bend to bend (isolated)

• Tolerances up to ±.030″ with multiple bends and features (e.g., formed box with flanges)

Multiple Form Parts (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.
