Precision CNC Machining
— Ultra-Tight Tolerances & Complex Parts | Sundar Industries
Sundar Industries specializes in precision CNC machining with tolerances down to ±0.005mm. We use advanced 5-axis machines, climate-controlled environments, and CMM verification for mission-critical components.
For applications that demand the highest level of accuracy, Sundar Industries offers specialized precision CNC machining services. We consistently achieve tolerances of ±0.005mm or better on critical features. This capability is the result of a controlled synergy between our advanced 5-axis equipment, rigorous tooling and fixturing strategies, and climate-controlled inspection environments. We serve industries where component failure is not an option, including aerospace, medical devices, and high-performance automotive.

At Sundar Industries, we define precision as the ability to consistently deliver tolerances of 0.01 millimeters or tighter — not occasionally, but every time. This level of accuracy goes beyond high-end machinery. It requires a mastery of thermal dynamics to control expansion and contraction during cutting, an understanding of tool deflection to maintain geometry under load, and a deep knowledge of how different materials respond to machining forces. Our engineers bring this expertise to every project, ensuring that your most critical features are machined with absolute consistency. When we say precision, we mean it — and we prove it, part after part.
Key Pillars

Advanced Multi-Axis Machining
We use 5-axis machining to complete complex geometries in a single setup. This eliminates "stack-up errors" from multiple re-fixturing, which is critical for maintaining true position and overall accuracy.

Thermal Stability
Our workshop is climate-controlled to minimize dimensional drift caused by temperature fluctuations. Even a change of a few degrees can cause a part to expand beyond its specified limits.

Precision Tooling & Fixturing
We use high-quality tooling and custom-designed fixturing to minimize tool deflection and ensure the cutting edge remains precisely on the programmed path, even under heavy loads.

GD&T Expertise
Our engineers are experienced in interpreting and meeting complex Geometric Dimensioning and Tolerancing (GD&T) requirements, including true position, runout, and profile tolerances.
