Buying tips

## Buy it with confidence.

What experienced buyers put in the RFQ and check on arrival.

  * Share 3D models and fully toleranced drawings with GD&T, and flag critical-to-function dimensions.
  * Ask for a first-article inspection report with CMM data before releasing production.
  * Specify surface finish (Ra), plating or anodising, and rust-preventive packing for sea freight.

Machining & precision questions

## Straight answers.

Anything else, ask us directly. A principal replies, not a bot.

[anirudh@sourcesquid.co](mailto:anirudh@sourcesquid.co)

### Is Bengaluru good for precision machining?

Yes. Bengaluru's Peenya and nearby industrial estates have many CNC shops serving machine tools, aerospace and electronics, with good tolerance capability and quality systems.

### Can Indian suppliers work to tight tolerances?

Established export shops routinely hold ±0.01 mm on CNC-turned and milled parts, and tighter on ground features. Confirm capability with a sample and a CMM report.

### What certifications should a machining supplier have?

ISO 9001 is the baseline. Automotive work usually needs IATF 16949 and aerospace work AS9100.
