One-Piece 5-Axis
Blisks (Integrally Bladed Disks)
Integrally bladed disk (blisk) machining — blades and hub cut from a single billet in 5-axis simultaneous milling. No attachment slots, no fir-tree joints, 20–40% lighter than assembled bladed disks, blade-to-disk concentricity ≤ 0.005 mm. For aerospace gas turbines, turbochargers, UAV propulsion, and high-performance compressors.

Why It's Difficult
Why Blisk Machining Is Exceptionally Demanding
A blisk concentrates every impeller and turbine blade challenge into one part — plus the full disk structure, attachment geometry, and inter-blade passage access — all from a single billet without the option of rework by replacement.
🌀
Complex Inter-Blade Passages
Every blade passage on a blisk is enclosed on two sides (adjacent blades) and the disk floor — similar to a closed impeller. All passage surfaces must be reached with 5-axis simultaneous tilt and long-reach tooling without collision.
💎
Scrap Risk
A blisk is machined from a single high-value billet. Any error at the final blade is the loss of the entire part. HXC uses in-process probing and staged first-article inspection to catch deviations before they become scrap.
⚙️
Material Challenges
Aerospace blisks use titanium or nickel superalloys. Long machining times at low feed rates generate heat that can affect material properties. Controlled cutting strategy, temperature monitoring, and CBN tooling are mandatory for all superalloy blisks.

FAQ
Frequently Asked Questions About Blisk Machining
Engineering and procurement questions answered by our 5-axis machining team.
Yes — HXC machines integrally bladed disks (blisks) from a single billet in 5-axis simultaneous machining. The blade and disk are never separate — the entire structure is cut from one piece of material. This eliminates the blade attachment joint (fir-tree or dovetail), reduces part count, and achieves blade-to-disk concentricity ≤ 0.005 mm that assembled bladed disks cannot match.
All blades are machined from the same rotational datum on the disk in a single setup. An in-process probing routine measures the first blade after semi-finish and adjusts the tool offset before finishing all blades. CMM inspection verifies every blade at multiple cross-sections — blade-to-blade profile deviation ≤ 0.015 mm is reported in the inspection package.
HXC uses 5-axis simultaneous CNC machining centres with table tilt + head rotation (trunnion configuration) for blisk machining — this gives the full angular freedom needed to reach all inter-blade passage surfaces and blade root fillets. For superalloy blisks, we use high-rigidity machines with CBN tooling and dedicated vibration-monitoring to detect and prevent chatter before it damages the part.
Four-stage risk control: (1) Simulation — all toolpaths are gouge-checked and simulated before cutting; (2) First-blade inspection — the first blade is fully CMM scanned before the remaining blades are machined; (3) Staged in-process probing — tool offset is verified at semi-finish before committing to final passes; (4) Material buy-off — raw billet is spectrally verified before machining begins. Combined, these reduce scrap risk to near zero.
(1) No attachment slots — no fir-tree or dovetail slots means no stress concentration at blade roots; (2) Lighter — 20–40% weight reduction by eliminating attachment features and disk rim; (3) Better aerodynamics — no leakage gaps at blade root; (4) Higher blade-to-disk accuracy — concentricity is machined, not assembled; (5) Fewer parts — one blisk replaces a disk plus N blades plus N retaining features.
A blisk is a one-piece structure — individual blades cannot be replaced. For damaged blades: (1) If damage is within allowable blend limits, HXC can re-machine the affected blade to restore profile; (2) For more severe damage, laser metal deposition (LMD/DED) can restore blade material, followed by re-machining of the repaired section. Repair feasibility depends on material and extent of damage — contact our engineers.
Minimum blisk OD: Ø30 mm (microblisk for UAV or medical application). Maximum blisk OD on our 5-axis trunnion machines: Ø350 mm. For blisks Ø350–500 mm, we use a gantry 5-axis with extended reach tooling — contact us for feasibility check.
Ti Grade 5 prototype blisk (new programme, full inspection): 10–16 days. Al 7075 blisk: 8–12 days. Inconel superalloy blisk: 16–24 days. Small batch (3–10 pcs): add 5–8 days per unit. Every blisk receives full CMM blade scan — this is non-negotiable.
