We blend advanced machine platforms, rigid process controls, and experienced operators to produce complex parts with repeatable 5–10µm tolerances. Our facility is purpose-built for high-mix, high-precision work — from single prototypes to fully validated production runs — with end-to-end traceability and inspection at every stage.
Zetford: Precision CNC Machining Services
Zetford is an ISO-certified precision contract manufacturer in India specializing in custom CNC turning, multi-axis turn-mill, and large-diameter VTL machining. We offer end-to-end manufacturing—from raw material sourcing to multi-part sub-assembly—serving Tier-1 OEMs and engineering buyers across the USA, Europe, and India. Operating in-house high-rigidity CNC machines from industry-leading brands such as LMW, paired with advanced Siemens controllers, we achieve exceptional dimensional stability, tight tolerance accuracy, and superior complex 3D contour profile machining and surface finishing.
Our state-of-the-art facility features high-power, high-torque spindle machinery tailored for difficult-to-machine alloys, including Inconel, SS316, and Duplex Stainless Steel. Equipped to manage both low-volume prototype builds and customer bulk-volume manufacturing, Zetford maintains an audited, robust supplier network to seamlessly scale capacity to meet aggressive timelines. We take end-to-end responsibility for quality, precision inspection, and on-time delivery across critical global industries.

Our core competency is advanced CNC turning combined with 5-axis turn‑mill operations that allow machining of complex geometry in a single setup. This reduces cumulative error and fixturing variability, enabling consistent tolerances in the 5–10µm range on critical dimensions. We plan toolpaths, cutting strategies, and thermal compensation to protect dimensional integrity across long cycles.
Such accuracy is essential for demanding sectors — Automotive powertrain components, Defense mechanisms, Railway safety hardware, and Medical implant or instrumentation parts. Zetford pairs engineering simulation with shop-floor discipline so parts meet form, fit, and function the first time.

The Anatomy of Precision: CNC Turn Mill Machining
Material Expertise
Material Mastery: From Titanium to Technical Plastics
Mild Steel & Steel Alloys
Machining mild steel and structural alloy steels requires optimized cutting speeds, balanced chip control, and stable tool life management. We machine high-strength components from materials like AISI IS 2062 , 1018, EN3, EN8, 1045, EN9, EN19, EN24, EN31, 4130, 4140, 4340, 8620, 20MnCr5, 16MnCr5, 8620, D2, H13, O1 & A2 with parameters tuned to ensure high material removal rates, excellent thread quality, and distortion-
Stainless Steel & Inconel Titanium
CNC machining across a broad spectrum of materials stainless steel SS304/L, SS316/L, Duplex and Super Duplex, SS410, SS420, SS430, titanium, and high-temperature nickel superalloys like Inconel 600, 625, 718, X-750, Hastelloy C276, Monel 400 & titanium. Utilizing high-torque CNC machinery and optimized tooling parameters, we consistently achieve tight dimensional tolerances, superior surface finishes, and structural integrity.
Light Weight Alloys
Our turning centers handle high-speed finishing and fine surface quality for lightweight alloy components—including Aluminum 6061-T6, 6063-T6, 6082-T6, 7075-T6/T651, 2024, 5052, 5083, 5754 and 3003, 2024, AD12 Cast Grades —used in transportation, aerospace, and electronics, balancing chatter-free cutting with tight dimensional control. Copper C101 OFHC, C110 ETPC145, Beryllium copper, Phosphor bronze, Aluminium bronze. Brass C360 free-cutting, C260, C464, CuZn39Pb3.
Engineering Plastics
Engineering plastics including Delrin - Acetal (POM), Polycarbonate (PC), PTFE (Teflon), PEEK, Nylon (PA6/PA66), MC Nylon, Ultem (PEI), UHMW-PE, HDPE, ABS and Bakelite/FR4 are machined with strict attention to thermal expansion, optimized tool geometry, and stress-free fixturing to meet tight tolerances and functional finish requirements for electrical insulation, chemical sealing, wear resistance, and lightweight structural parts.
Measured Confidence
Advanced Inspection & Quality Assurance
Quality at Zetford is driven by metrology. Our in‑house CMM lab performs coordinate measurement on production lots and first articles, validating geometric dimensioning and tolerancing, form, and positional references at micron-level resolution. Every critical feature is documented with calibrated reports and traceable measurement protocols.
We maintain NABL-calibrated gauging, run capability studies (Cp/Cpk), and hold certifications including ISO 9001:2015 and IATF 16949. Inspection steps are integrated into process plans, with gated approvals before parts progress to finishing or shipment.
- CMM measurement & reporting
- First-article inspection & batch sampling
- Traceable, calibrated gauges and protocols

Surface Finishing and Integrity
Surface treatment is critical for corrosion resistance, wear performance, and assembly readiness. Zetford offers a full suite of finishing and plating services — anodizing for aluminum, Zinc‑Nickel and electroless nickel options for ferrous parts, chemical conversion coatings (Alodine), and passivation for stainless steel. We coordinate post‑machining stress‑relief when required, and control surface roughness to meet sealing and mating specifications.
Secondary operations such as deburring, bead‑blasting, precision polishing, and selective masking are carried out to prepare components for immediate assembly. All plating processes include thickness validation and adhesion checks to ensure long‑term part integrity.
Connected Manufacturing
