FAQs

What is CNC rapid prototyping and why do Apple and Tesla rely on it?

CNC rapid prototyping uses high-precision machining to turn digital designs into physical parts.

• Apple uses it for consumer-device enclosures, buttons, frames, and internal structural components.

• Tesla uses it for EV structural parts, battery components, housings, brackets, and motor hardware.
  It allows both brands to test form, fit, and performance quickly before mass manufacturing.

Which company achieves tighter machining tolerances—Apple or Tesla?

Apple wins in ultra-tight tolerances, especially for small aesthetic parts.

• Apple typical tolerance: ±0.005–0.01 mm

• Tesla typical tolerance: ±0.02–0.05 mm (for large structural parts)
  Consumer electronics require micron-level detail, while Tesla focuses on strength and durability over microscopic precision.

What materials do Apple and Tesla use for CNC prototypes?

Apple:

• 6063-T6 aluminum

• 7075 aerospace-grade aluminum

• Stainless steel (Watch)

• Precision plastics for internal frames

Tesla:

• 6061-T6 & 7075 aluminum for motor housings

• High-strength steel

• Titanium brackets

• Copper components for battery modules

Who has faster prototype turnaround—Apple or Tesla?

Both are fast, but for different reasons:

• Apple: 1–3 days for high-precision cosmetic prototypes

• Tesla: 3–7 days for large EV structural components
  Tesla parts are much larger, requiring different machining setups and testing.

Does Apple or Tesla use more advanced CNC machine types?

Both use multi-axis machines, but:

• Apple invests heavily in 5-axis micro-machining for small features.

• Tesla uses large-format 5-axis gantry CNCs for EV chassis and motor components.

How do Apple and Tesla control quality during CNC prototyping?

Apple:

• CMM (Coordinate Measuring Machine) scanning

• Laser surface deviation mapping

• Cosmetic inspection under 5–10× magnification

Tesla:

• Stress testing

• Fatigue load simulation

• Dimensional inspection for large assemblies

• Thermal behavior evaluation for EV components

Which company spends more on CNC prototyping per part?

Generally Tesla, due to scale and size.

• Apple prototypes: $200–$1,200 per part

• Tesla prototypes: $2,000–$10,000+ depending on structure size

Is CNC machining still essential for Apple and Tesla despite 3D printing?

Yes.

• Apple: CNC provides the surface finish required for final consumer devices.

• Tesla: CNC delivers structural accuracy and metal strength that 3D printing cannot fully replace.
  Both often combine CNC + additive manufacturing for hybrid workflows.

Which company is more cost-efficient in CNC prototyping?

Apple tends to be more cost-efficient because:
