Capability Decision Logic

Tolerance Selection Guide

Required Tolerance Recommended Route

±0.003mm or tighter HARDINGE turning, CITIZEN Swiss, Wire EDM

±0.005mm DMG MORI ALX2000, Swiss machines

±0.010mm Standard DMG MORI turning/milling

±0.050mm Haas fast response cell

Looser Any machine, optimize for cycle time

Part Type Routing

Turned Parts (rotational):

IF diameter > 200mm → CANNOT MAKE (max Ø270mm on Hardinge) IF diameter > 150mm AND tolerance < ±0.005mm → HARDINGE only IF diameter ≤ 50mm AND high volume → CITIZEN Swiss IF length > 700mm → CANNOT MAKE (max Z700mm on NLX2500 Single) IF tolerance ≤ ±0.003mm → HARDINGE or CITIZEN ELSE → DMG MORI NLX2500 (twin for short parts, single for long)

Milled Parts (prismatic):

IF any dimension > 700mm → CANNOT MAKE IF 5-axis required AND part ≤ 470x350x510mm → NMV3000 (best automation) IF 5-axis required AND part ≤ 650x650x550mm → DMU50 IF 4-axis sufficient AND part ≤ 700x500x450mm → Vertical VMC IF simple prototype → Haas Mini Mill

Complex Geometries:

IF hardened material (>50 HRC) → EDM route IF sharp internal corners required → Wire EDM IF through-profile cuts → Wire EDM IF cavity/pocket in hardened steel → Spark EDM

Material Considerations

Material Type Notes

Aluminium All machines, optimize speeds

Stainless (303/304/316) Consider CITIZEN LFV for chip breaking

Titanium 5-axis mills, reduce speeds, rigid setups

Inconel/Hastelloy Reduced feeds, consider EDM for features

Hardened steel (>50 HRC) EDM only for machining, or machine before hardening

Plastics/Delrin Swiss machines excellent, watch for heat

Brass/Bronze All machines, free-machining

Example Queries and Responses

Query: "Can we turn a Ø150mm x 400mm shaft in 316SS to ±0.008mm?" Response: YES - Use DMG MORI NLX2500 Single Spindle

• Diameter OK: Ø150mm < Ø200mm capacity

• Length OK: 400mm < 700mm Z-travel

• Tolerance OK: ±0.008mm achievable (machine capable of ±0.010mm)

• Material: 316SS fine, consider live tooling for any milled features

Query: "Can we make a 5-axis aerospace bracket 500x400x300mm in Ti-6Al-4V?" Response: YES - Use DMG MORI DMU50

• Envelope OK: 500x400x300 fits in 650x650x550mm

• 5-axis capability: Yes

• Material: Titanium requires reduced parameters, rigid fixturing

• Note: NMV3000 too small (470x350x510mm)

Query: "Small precision medical pin Ø3mm x 25mm, ±0.002mm tolerance, 10,000 qty?" Response: MARGINAL - CITIZEN Swiss closest but tolerance challenging

• Size OK: Well within Ø50mm capacity

• Volume: Swiss machines ideal for high volume

• Tolerance: ±0.002mm tighter than ±0.003mm capability

• Recommendation: Discuss with engineering - may need post-process grinding or accept ±0.003mm
