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.

anirudh@sourcesquid.coIs 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.
