Capabilities
The machine list, with the numbers we sign off on.
Every machine group across both plants, the envelope it handles, the tolerance we will commit to on your drawing, and the materials we run on it every week. Filter it the way your engineers would.

| 18 five-axis VMCs (10 × 650 class, 6 × 1000 class, 2 × high-speed 500 class), 6 HMCs, 15 turning and turn-mill centres, 5 grinders and 3 EDM machines. | |||||||
Machines are 5-axis machining centres from leading German and Japanese builders, all under 8 years old, with spindle and axis calibration every 6 months. Model list on request under NDA.
Materials
What we cut every week.
Bar, plate, forgings and castings, bought from approved mills with EN 10204 3.1 certificates, or free-issued by you. Every heat number is traced to the part.
| Material | Grades | Typical parts | Notes |
|---|---|---|---|
| Aluminium | 6061-T6, 7075-T6 / T7351, 2024-T351 | Manifolds, motor housings, aerospace brackets | Anodise Type II and III, chromate conversion through approved partners |
| Stainless steel | SS 304 / 304L, 316 / 316L, CF8M castings | Fittings, impellers, valve bodies, shafts | Passivation to ASTM A967, electropolish on request |
| Inconel | Alloy 718 (AMS 5662 / 5663) | Engine brackets, high-temperature fittings | Dedicated cell, ceramic and coated-carbide tooling |
| Titanium | Ti-6Al-4V Grade 5 (AMS 4928) | Actuator clevises, aerospace lugs | Chips segregated and recycled by grade |
| EN steels | EN8, EN19, EN24, EN31, EN353 | Shafts, rollers, gear blanks, pins | Through-hardening and case carburising, then ground |
| Cast iron | FG 260 grey iron, SG 500/7 ductile iron | Pump casings, gearbox housings, caliper brackets | Castings from three audited Coimbatore foundries, or yours |
Tolerances & finish
The number on the drawing is the number you get.
| Feature | Standard | Best we hold |
|---|---|---|
| Linear dimensions | ISO 2768-m | ±0.005 mm |
| Bores | H8 | H6, Ø6 to Ø120 |
| True position | 0.05 mm | 0.01 mm |
| Flatness | 0.02 / 100 mm | 0.005 / 100 mm |
| Roundness, ground | 0.01 mm | 0.003 mm |
| Surface finish | Ra 1.6 | Ra 0.4 |
| Threads | 6H / 6g | 4H5H, thread-milled, 100% gauged |
Part envelope
From Ø3 pins to 1‑metre housings.
Larger than this? Ask. We machine oversize castings on partner floor-borers in Coimbatore under our own inspection.
Batch sizes & lead times
50 pieces or 50,000. Same process.
Samples go through the same PPAP or FAI route as series parts, so the first article you approve is the part you get at volume.
Beyond machining
Delivered ready to fit.
Most buyers want one supplier and one PO per part number. We manage finishing and assembly under our quality system and ship the part ready for your line.
Assembly & test
Bearing and seal pressing, helicoil and insert fitting, torque-audited sub-assemblies. Pressure-decay leak testing to 10 bar, 100% on EV and hydraulic parts.
Finishing
Anodising, hard anodising, passivation, zinc-nickel, phosphating, induction hardening and heat treatment through five audited partners within 25 km.
Marking & packing
Laser marking with part number, heat number and date code, or DataMatrix. VCI wrap and ISPM-15 crates for sea freight, returnable totes for domestic lines.
