In One Sentence
Mazteknik supplies high-precision cutting tools, tight-tolerance holders and metrology to aerospace and defense shops machining titanium, Inconel, and composites — single source, traceable.
What Aerospace Machining Demands
Aerospace parts (airframe members, turbine blades, landing-gear components, defense housings) are made from thin-wall, hardened or hard-to-machine alloys. A single tool failure can scrap a high-value part.
That's why aerospace shops never compromise on:
- Precision holders (HSK, BIG-PLUS, Capto) — balanced and repeatable at high RPM
- Right carbide grade (TiAlN, AlCrN, AlTiN nano) — thermal-shock resistant
- Micron-level metrology (CMM, Zoller presetters, digital micrometers)
Tooling by Material
| Material | Recommended Tool | Strategy |
|---|---|---|
| Ti-6Al-4V titanium | TiAlN-coated carbide end mill | Low Vc, high fz, flood coolant |
| Inconel 718 / 625 | Round-insert ceramic | High Vc, continuous engagement |
| 7075 / 2024 aluminum | Polished carbide end mill | High Vc, dry / MQL |
| Carbon composite (CFRP) | PCD diamond end mill | Low Vc, aggressive vacuum |
| Hardened 4340 | CBN insert | High Vc, fine geometry |
How Mazteknik Approaches Aerospace
For aerospace work we supply traceable, serialized tools. Material certificates ship with every batch — you know which lot every tool came from.
For high-value carbide end mills, our Tool Regrinding service uses a Zoller Genius 3 measuring system (micron precision) to restore geometry, with a measurement report on delivery.
Frequently Asked
Why HSK holders for aerospace? The HSK interface contacts on both the taper and the face — repeatability at high RPM beats BT/CAT. Standard for electric spindles running above 20,000 RPM.
Can I machine Inconel dry? No. Inconel's thermal conductivity is low; without coolant the heat loads onto the cutting edge and tool life collapses. High-pressure (70+ bar) through-tool coolant with round-insert ceramics gives the best result.
Carbide or PCD for CFRP? For 2–3 parts, carbide works. For volume production, PCD diamond end mills extend tool life 50–100× — CFRP's abrasive fibers consume carbide quickly.
