Precision Machining vs. Super Precision Machining: What’s Right for Your Equipment?
Problem
If you build semiconductor manufacturing equipment, pharmaceutical manufacturing machines, oil drilling equipment, or high-performance automated machinery, you need parts that fit perfectly. But which do you need: precision machining or super precision machining? It’s not always easy to decide. One small error can slow down your factory or even stop it completely. That hurts you, your customers, and your profits.
Agitate
Imagine running a production line 24/7 only for a machine to fail because a shaft or plate was made just a little too loose or tight.
- You lose thousands of dollars for every hour equipment stands still.
- Your customers expect zero defects, especially in semiconductor or pharma lines where a tiny error can ruin a whole batch or wafer.
- Oil drilling tools and automation parts need to withstand pressure, heat, and movement all day, every day. If the wrong machining process was picked, you risk costly repairs, rejects, and even safety problems. Many suppliers over-promise “precision” but don’t deliver the tolerances you really need.
Solution
We offer precision CNC machining and super precision CNC machining for all your challenging needs. That means you’ll never pay for more than you need, yet always get the tightest fits and smoothest finishes where it matters most.
What Is Precision Machining?
Precision machining uses CNC tools to cut and form metal or plastic parts with tight tolerance:
- Tolerances: ±0.001 inch (about 25 microns)
- Surface Finish: Ra 0.4–1.6 µm (good, but not mirror-finish)
- Best For: Engine blocks, hydraulic valves, high volume plates, or components for electronics and machinery [1][4].
See what we can do:
- Custom high precision titanium sealing parts for harsh deep-sea environments
- Precision wear-resistant carbon steel shafts for industrial machines
- High precision custom 5 axis machining aluminium parts for semiconductor industry
What Is Super Precision Machining?
When you need parts even tighter and even smoother, only super precision machining delivers:
- Tolerances: ±0.00004 inch (about 1 micron, thinner than a human hair)
- Surface Finish: Ra <0.1 µm (mirror-like finish needed for optics, semiconductors, or medical implants)
- Best For: Semiconductor wafers, fiber optic connectors, lasers, medical implants, and all parts where microscopic differences matter [1][4].
Precision vs. Super Precision: Data Table
| Precision Machining | Super Precision Machining | |
|---|---|---|
| Tolerances | ±0.001" (25 µm) | ±0.00004" (1 µm) |
| Surface Finish | 0.4–1.6 µm | <0.1 µm |
| Cost | $50-$500 per part | $500-$5,000+ per part |
| Lead Time | 2–4 weeks | 6–12 weeks |
| Tools | CNC, EDM, 3/4/5 axis mills | Diamond turning, nano-CMM, air spindles |
| Best For | Industrial, electronics, oil | Optics, medical, semiconductors |
Numbers based on real orders, industry standards, and published machining reports [1][4].
How Do You Choose?
-
What tolerances do you truly need? For semiconductor masks or optical parts, super precision is required. For frames, bases, or brackets, precision is usually enough.
-
What finish does your part need? If you need a mirror finish or ultra-low friction, only super precision can achieve Ra <0.1µm.
-
What’s your budget and deadlines? Super precision costs more and takes longer—be sure you need it.

Precision & Super Precision: FAQ
What’s the cost difference?
Precision machining is budget-friendly for most parts. Super precision costs 5–10x more but is critical for high-tech and medical devices [1][4].
Will precision parts last as long?
If your application doesn’t demand sub-micron accuracy, yes. For products like connectors, machined aluminium plates, or robust shafts, precision is perfect.
Do I need both?
Some machines use both: most parts made precisely, a few critical contacts or guides made super precise. Ask us—our engineers help you decide and save you money.
