1. What Is Driveshaft CNC Machining?

A driveshaft is a key mechanical component that transfers power between engines, gearboxes, and wheels.
Through precision CNC machining, driveshaft parts can achieve:

• Stable torque transmission

• High mechanical strength

• Perfect spline alignment

• Smooth rotation and minimal vibration

• Tight dimensional matching

CNC machining ensures every shaft meets strict tolerance and durability requirements.

2. Why CNC Machining Is Ideal for Driveshaft Components

✔ Precision for Rotating Parts

Rotating shafts require extremely accurate concentricity, straightness, and diameter control.
CNC turning + milling provides the ideal solution.

✔ Excellent Material Versatility

Typical driveshaft materials include:

• 4140 / 4340 alloy steel

• Carbon steel

• Stainless steel (304 / 316)

• Aluminum 7075 / 6061

• Titanium alloy

✔ Perfect for Custom Splines & Yokes

CNC machining supports:

• Involute splines

• Straight splines

• Internal splines

• Universal joint yoke machining

• End-flange machining

✔ High Strength & Durability

Heat treatment options such as:

• Nitriding

• Induction hardening

• Quenching

• Tempering

3. Typical CNC-Machined Driveshaft Components

6. FAQ (People Also Ask)

Q1: What tolerance can CNC machining achieve for driveshafts?

Most shafts can be machined to ±0.01 mm, while spline interfaces can reach ±0.005 mm.

Q2: Do you provide spline machining?

Yes—internal and external splines, involute splines, and custom non-standard spline profiles.

Q3: Can I order only one prototype?

Yes. We support one-off prototypes, small batches, and mass production.

Q4: Are surface treatments available?

Yes—black oxide, anodizing, zinc plating, nitriding, and polishing.
