Aluminium CNC Machining in Gurgaon | 6061, 6082, 7075 Turning & Milling Job Work
Aluminium is the first choice for lightweight, corrosion-resistant machined parts across automotive, hydraulic, and industrial electronics industries. We provide aluminium CNC turning and aluminium CNC milling job work in Gurgaon for grades 6061-T6, 6082-T6, 7075-T6, 5083, and 2024 — with finishes suitable for direct anodising.
Why aluminium is the preferred material for lightweight machined parts
Aluminium alloys combine three properties that make them dominant in precision machining: low density (roughly one-third the weight of mild steel), natural corrosion resistance from a self-forming oxide layer, and excellent machinability that allows high cutting speeds and fine surface finishes without the tool wear rates associated with steel. For industries where every gram counts — drones, automotive sub-assemblies, industrial fixtures, and medical devices — aluminium is the default starting point.
Despite being softer than steel, aluminium machining demands respect for process details. The correct tool geometry (higher rake angles, polished flutes) prevents the material from smearing or building up on the cutting edge. Effective chip evacuation — particularly in deep pockets or deep-hole drilling — avoids re-cutting chips that score the finished surface. A controlled coolant strategy, whether flood coolant or mist, keeps the cut temperature stable and flushes chips clear. When these factors are managed, aluminium produces clean, burr-minimal parts at throughput rates significantly faster than equivalent steel work.
The most widely used grades in industrial CNC work are 6061-T6 — the general-purpose workhorse with excellent weldability and anodising response; 6082-T6 — a structural grade common in European automotive supply chains; 7075-T6 — a high-strength alloy approaching mild steel in tensile strength, used in high-load industrial and motorsport applications; 5083 — preferred where marine corrosion resistance or cryogenic service is required; and 2024 — a high-fatigue-strength grade used in structural and high-stress applications. Our CNC turning, CNC milling, and precision machining capability covers all these grades across both turned and prismatic geometries.
Our workshop in Sector 18, Sarhol, Gurgaon is 10–15 km from IMT Manesar and serves aluminium machining buyers across Gurugram, Faridabad, Noida, and Delhi NCR — from prototype single-offs to repeat production batches.

What makes aluminium machining reliable at our workshop
Correct Tool Geometry
High positive rake angle end mills and turning inserts designed for non-ferrous materials. Polished flutes prevent aluminium from welding to the cutting edge and smearing the finished surface.
Chip Evacuation Strategy
Deep pockets and blind holes in aluminium require controlled feed rates and peck drilling cycles. We manage chip evacuation to prevent re-cutting, which is the leading cause of poor finishes in aluminium milling.
Anodising-Ready Finish
Parts intended for anodising are machined with sharp tooling and left burr-free. Machined surfaces, cross-holes, and tapped holes are deburred and checked before dispatch to ensure the part is post-process ready.
Grade-Aware Setup
7075-T6 and 2024 behave differently from 6061 under cutting loads. We adjust cutting parameters by alloy to maintain consistent tolerance and finish across all grades we machine.
Aluminium CNC Machining FAQ
What aluminium grades do you machine in Gurgaon?
We machine all common structural and industrial aluminium alloys: 6061-T6 (the general-purpose standard for most industrial and automotive applications), 6082-T6 (preferred in European automotive supply chains for its higher yield strength), 7075-T6 (a high-strength alloy with tensile strength approaching mild steel, used in high-load and motorsport applications), 5083 (for marine, cryogenic, and corrosion-critical environments), and 2024 (a high-fatigue-strength grade for structural and high-stress applications). If your drawing specifies a grade not listed here, contact us — we can confirm availability and machinability.
Why is aluminium easier to machine than steel?
Aluminium is significantly softer than steel, which allows cutting speeds two to three times higher and generates lower cutting forces. This means less tool wear, faster cycle times, and better chip formation compared with machining mild or alloy steel. However, aluminium requires correct tool geometry — high positive rake angles and sharp, polished cutting edges — to prevent the material from smearing or building up on the tool face. Without the right tooling strategy, aluminium can actually produce worse surface finishes than steel.
What tolerances can you hold on aluminium CNC turning and milling?
For standard aluminium CNC turning and milling, we hold ±0.05mm as a general production tolerance. For precision requirements — fit-critical diameters, close-tolerance bores, or tight positional features — we work to ±0.02mm. Tighter tolerances are possible on specific features; send your drawing with the critical dimensions annotated and we will confirm what is achievable on your part geometry.
Can you machine aluminium parts ready for anodising?
Yes. Anodising is sensitive to machining quality — scratches, smearing, and burrs in machined surfaces show up as defects in the anodised finish. We use sharp, non-ferrous tooling and ensure machined surfaces are left clean and burr-free. All tapped holes, cross-holes, and sharp internal corners are deburred before dispatch. Parts are handled with gloves after final machining to avoid surface contamination. This makes our machined aluminium parts directly compatible with hard anodising, standard anodising, or colour anodising post-processes.
Do you machine 7075 aluminium for high-strength applications?
Yes. 7075-T6 is a zinc-series aluminium alloy with tensile strength in the range of 500–570 MPa — significantly higher than 6061-T6 (around 310 MPa). It is used in high-load structural components, drone frames, motorsport parts, and industrial fixtures where mass reduction is critical without sacrificing strength. 7075 machines well but is more sensitive to tool sharpness than 6061. We adjust cutting parameters accordingly to achieve consistent surface quality on 7075 jobs.
Can you handle aluminium CNC machining job work near IMT Manesar?
Yes. Our workshop is located in Sector 18, Sarhol, Gurugram — approximately 10–15 km from IMT Manesar. We regularly support Tier-1 and Tier-2 suppliers in the Manesar industrial belt with aluminium machining job work for automotive, HVAC, and electronics applications. Whether you need a prototype batch or repeat production orders, contact us with your drawing and quantity for a quote.
What is the surface finish achievable on aluminium machined parts?
Standard aluminium CNC turning and milling at our workshop produces Ra 1.6–3.2µm, which is suitable for most structural and functional applications. For parts requiring a finer finish — such as sealing faces, anodising-critical surfaces, or precision bore fits — we achieve Ra 0.8µm with finish-pass toolpath strategies and appropriate cutting conditions. If your drawing specifies a surface finish requirement, include it on the drawing and we will confirm achievability for your geometry.
