A no-nonsense guide to CNC machining costs, achievable tolerances, typical lead times, and which industries in Dubai get the most value from precision CNC work.
There's a lot of vague content about CNC machining online. This isn't that. This is a working engineer's breakdown of CNC capabilities, real costs, and practical advice from a workshop that's been machining in Dubai since 2002.
What CNC Machining Actually Achieves
Turning (CNC Lathe)
- ✓Diameter tolerance: ±0.01mm to ±0.005mm
- ✓Surface finish: Ra 0.4µm to Ra 1.6µm standard
- ✓Max swing: 600mm diameter, 3000mm between centres
- ✓Best for: Shafts, pins, flanges, couplings, hydraulic rods
Milling (CNC Machining Centre)
- ✓Position tolerance: ±0.02mm standard, ±0.005mm high-precision
- ✓Surface flatness: 0.01mm per 300mm
- ✓Max table size: 1200mm × 600mm
- ✓Best for: Housings, blocks, plates, jigs, dies, molds
CNC Laser Cutting
- ✓Kerf width: 0.2mm–0.5mm depending on material
- ✓Position accuracy: ±0.1mm on a 3000×1500mm sheet
- ✓Max thickness: 20mm mild steel, 12mm stainless, 10mm aluminium
- ✓Best for: Profiles, brackets, flanges, decorative panels
CNC Waterjet Cutting
- ✓Position accuracy: ±0.1mm
- ✓No heat-affected zone — critical for heat-sensitive alloys
- ✓Any material: Steel, aluminium, marble, glass, rubber, nylon, Teflon
- ✓Best for: Gaskets, seals, complex profiles, non-metals
Real Cost Breakdown: What Does CNC Machining Cost in Dubai?
This is the question everyone asks and nobody answers directly. Here's the honest breakdown:
Turning (simple shaft, one diameter):
- ✓Setup: AED 50–150
- ✓Machining: AED 80–200/hour
- ✓Simple 200mm shaft: AED 150–300 total
Milling (complex pocket work):
- ✓Setup and programming: AED 200–500
- ✓Machining: AED 120–300/hour
- ✓A typical gearbox housing half: AED 600–2,500
Laser cutting (sheet profiles):
- ✓Setup: AED 50–100
- ✓Cutting: AED 0.50–2.00/linear metre depending on thickness
- ✓Nesting 20 brackets on one sheet: AED 200–400 total
Waterjet (non-standard materials):
- ✓AED 120–250/hour of cutting time
- ✓10mm rubber gasket, 300mm × 300mm: AED 80–150
Key cost drivers:
- ✓Material cost (your material or ours — we can supply)
- ✓Tolerance tightness (±0.05mm vs ±0.005mm is 3× the machining time)
- ✓Surface finish requirement
- ✓Quantity (1 vs 10 vs 100 = very different unit costs)
- ✓Urgency (same-day premium applies)
Lead Times: What to Expect
| Job Type | Standard | Rush (Same-Day Available) | |---|---|---| | Simple turning (1-2 ops) | 24 hours | Same day | | Complex CNC milling | 2–5 days | 24 hours | | Laser cut profiles | 24–48 hours | Same day | | Waterjet gaskets | 24 hours | Same day | | Full machined assembly | 5–10 days | 48–72 hours |
Industries That Benefit Most from Dubai CNC Machining
Oil & Gas
Valve bodies, manifolds, flanges, and wellhead components need material traceability, dimensional reports, and often NDT inspection. We provide mill certificates and CMM reports on request.
Real project: A valve manufacturer needed 15 custom body forgings machined to API 6A tolerance. Completed with full dimensional report in 8 days.
Marine
Propeller shafts, rudder components, seacock bodies, and custom fittings. Marine environments require 316L stainless or bronze — materials we work with daily.
Real project: A superyacht in drydock needed 6 custom stainless shaft sealing flanges in 48 hours. Delivered.
Power Generation
Generator coupling hubs, flywheel adaptors, and crankshaft components — all requiring tight concentricity and surface finish to ensure vibration-free operation.
Construction and Heavy Equipment
Custom wear plates, bush housings, jig fixtures, and OEM replacement components. Often needed in 24 hours when a critical machine is down.
How to Send Us a Job
- ✓WhatsApp +971 56 671 8356 with photos of the part and description
- ✓Or email drawings to sales@altaefengineering.ae (DXF, STEP, PDF, or even a sketch)
- ✓We respond with feasibility and price within the hour during working hours
- ✓Drop your material or raw bar — or we supply from stock
- ✓Collect, or we deliver across Dubai
No job is too small. We've machined a single grub screw for an emergency repair and a 2-tonne custom housing for an industrial gearbox — in the same week.
Why Tolerance Selection Matters More Than You Think
A common mistake is specifying the tightest possible tolerance "just to be safe." This costs money and time without adding value.
- ✓H7 bore (±0.025mm on 50mm): Fine for most rotating fits
- ✓H6 bore (±0.016mm on 50mm): Only needed for precision rolling bearings
- ✓H5 bore (±0.010mm on 50mm): High-speed spindles — genuinely rare
Specify what your application needs. Our engineers will tell you if you're over or under-specifying.
