About This Service
CNC turning shapes rotating workpieces with stationary cutting tools. We use Swiss-type lathes for
sub-25 mm precision parts and standard CNC lathes for larger work. Live tooling enables mill-and-turn in one setup.
Three Capability Classes (Pick Yours)
We divide our turning work into three classes based on diameter. The class determines machine, tolerance, and price.
Class A - Small Precision
Diameter 3-25 mm. Tolerance plus/minus 0.005 mm. Surface finish Ra 0.4-1.6 micrometer. Swiss-type lathes (Citizen, Star). Best for medical pins, sensor housings, electronic contacts.
Class B - Standard Shafts
Diameter 25-100 mm. Tolerance plus/minus 0.01 mm. Surface finish Ra 0.8-3.2 micrometer. Standard CNC lathes (Haas, Mazak, Doosan). Best for drive shafts, motor shafts, hydraulic spools, fasteners.
Class C - Large Diameter
Diameter 100-300 mm. Tolerance plus/minus 0.02 mm. Surface finish Ra 1.6-6.3 micrometer. Heavy-duty CNC with steady rests. Best for large valve bodies, hydraulic rods, industrial rolls.
Live Tooling: 3 Reasons It Wins
Live tool = rotating cutting tool on the lathe turret. Eliminates moving parts to a separate mill.
Setup Count Drops 50%
Traditional turn-then-mill: 2 setups with 60-90 min of fixture time. Live tooling: 1 setup. Saves 30-50% cycle time.
Tolerance Improves 4x
Each re-fixturing adds plus/minus 0.02-0.05 mm error. One setup means tighter accuracy across all features. Critical for cross-drilled holes and milled flats.
Net Cost Savings 15-25%
Per-part cost up 20-30% due to higher machine rate, but total time savings dominate. Net 15-25% cheaper for complex parts.
Why Choose Our CNC Turning
plus/minus 0.005 mm on Swiss
Tightest tolerance for small precision parts. Medical pins, sensor housings, contacts.
Live Tooling Capability
Mill, drill, and tap in the same setup. 80% of our lathe fleet has live tooling.
Diameter 3-300 mm
From 3 mm medical pins to 300 mm large valve bodies. Length up to 1000 mm.
Post-Heat-Treat Machining
Rough turn before heat treat, finish turn after. Essential for case-hardened parts.
50+ Bar Stock Materials
Aluminum, brass, copper, steel, stainless, titanium, plastics. Standard diameters in stock.
Medical-Grade Materials
303 stainless, titanium Grade 5, biocompatible. ISO 13485 certified for medical device parts.
