Performance Auto Lightweight CNC Parts: Titanium Rods & 7075 Brackets, ±0.005mm, Small-Batch Racing Programs
Lightweight parts for racing and performance cars are the most satisfying - and the most demanding - work in CNC: titanium rods, 7075 aluminum brackets, expensive materials, small batches (tens to a few hundred per season), fast revisions, and every piece must carry traceable material, process and inspection data. A racing part failure is not a money problem.
Project Background & Challenge
A race engineering team was developing lightweight chassis and powertrain parts for a prototype: TC4 titanium rods (turn-mill composite, tolerance ±0.01mm) and 7075-T6 aluminum suspension brackets (hole positions ±0.005mm, anodized), 80 pieces each for the first batch, iterating by season. They had been machining in Europe - high piece prices, time-zone friction, and a month or more per iteration.
The challenges: titanium runs hot and wears tools fast, so dimensional consistency is hard to hold; 7075 thin-wall brackets are clamping-sensitive; and small-batch iteration demands a full first-article check every round - no "good enough this round, fix it next round" mentality.
BQUQ Process Solution
Titanium Process Package
TC4 rods run at a conservative speed-and-feed window with flood coolant and dedicated coated inserts; tool life is documented per insert so "late-life dimensional drift" is caught before it happens. 7075 brackets use soft jaws plus a vacuum chuck, roughing and finishing separated with stress relief between, and thin walls locally supported.
Full Traceability
Every part gets a unique trace number linking material heat, machine, operator and inspection data. Full dimensional reports and material certificates ship per batch, meeting racing documentation requirements.

Quality Control & Delivery
First article is fully confirmed each iteration before release. Titanium parts get hardness and material re-verification, and CPK on critical features ships per batch. Samples in 7 days, production in 2 weeks, season revisions answered in 48 hours - at a clear saving versus the European source.

FAQ
Is titanium machining expensive and slow?
Titanium costs more than aluminum because of material and tooling, but on small batches we manage tool life per insert to keep price predictable; samples in 7 days and production in 2 weeks beat overseas lead times by weeks.
Can you deliver full racing documentation?
Yes. A per-part trace number ties material heat, machine, operator and inspection data; full dimensional reports and material certificates ship with every batch.
Do you take orders of just a few dozen pieces?
Yes. The multi-process, low-volume line is built for exactly this - 50 pieces is a normal batch, and revision samples leave in 48 hours.
