What Is 4-Axis CNC Machining?

4-Asse Machining CNC is an advanced manufacturing tecnologia that builds on 3-axis machining (X, Y, Z linear axes) by adding a rotary axis (A or B Axis)—a rotating table that spins the workpiece around one of the linear axes. This extra axis lets the machine access multiple sides of a part in a single setup, eliminating the need for manual repositioning and unlocking more complex geometries than 3-axis systems.​

IL Panoramica del processo è semplice: A CNC (Controllo numerico del computer) system interprets CAD designs to synchronize the linear axes (X/y/z, controlling the cutting tool) e il rotary axis (controlling the workpiece’s rotation). The two common rotary axis configurations are:​

• A-Axis: Rotates the workpiece around the X-axis (ideal for long, cylindrical parts like shafts).​

• B-Axis: Rotates the workpiece around the Y-axis (better for shorter, irregularly shaped parts like brackets with multi-sided features).​

To explain “Come funziona” simply: Imagine a 3-axis machine that can spin your part like a rotisserie while cutting it. Per esempio, when making a gear, the 4-axis machine cuts the gear teeth on the outer circumference as the rotary axis turns the part—all in one run, no need to stop and reposition. This is the core value of 4-Asse Machining CNC: combining linear precision with rotational flexibility to streamline production of multi-sided parts.

Whether you need to machine a single titanium shaft or 10,000 brass gears, our 4-axis capabilities scale to match your project’s complexity and volume.

The 4-Axis CNC Machining Process

Nostro processo passo-passo is optimized to leverage the rotary axis for efficiency and precision, from design to finished part:​

1. Design and CAD Modeling: We start by reviewing your CAD model (or creating one from sketches). Our engineers focus on optimizing the design for 4-axis machining—e.g., ensuring features on cylindrical surfaces are aligned to the rotary axis to avoid unnecessary setups. Per prototipi, we offer free design feedback to improve manufacturability.​

2. Programmazione di cam: The CAD model is imported into CAM software (Mastercam, SolidWorks CAM), where we program Percorsi degli utensili for both linear and rotary axes. We synchronize the rotary axis rotation with linear tool movements—for example, programming the A-axis to spin 90° while the Z-axis lowers the cutting tool to add a slot on a shaft’s side.​

3. Setup and Calibration: The workpiece is clamped to the rotary table (custom fixtures are used for irregular shapes). We calibrate the rotary axis using laser measuring tools to ensure alignment with linear axes (critical for precision). Utensili da taglio (PER ESEMPIO., mulini finali, esercitazioni) are loaded, E coolant systems are activated to prevent overheating.​

4. Esecuzione di lavorazione: The CNC system runs the program, synchronizing linear (X/y/z) and rotary (A/B) movements. Per esempio, when machining a gear, the rotary axis spins the part at a steady speed while the X/Y axes move the cutting tool to cut teeth. We monitor the process in real time to adjust speeds or coolant flow if needed.​

5. Post-Machining Inspection: Dopo la lavorazione, parts undergo rigorous checks. Usiamo i CMM (Coordinare le macchine di misurazione) to verify linear dimensions and angular measurements (for rotary axis features). Parts with rough edges move to sfacciato O macinazione for finishing.​

Rotary Axis Integration Review: Per parti complesse, we review the rotary axis performance (PER ESEMPIO., rotation smoothness, precisione di posizionamento) to refine future programs—ensuring consistent quality for repeat orders.

Key Advantages of 4-Axis CNC Machining

Compared to 3-axis machining (which requires multiple setups for multi-sided parts) and 5-axis machining (which is more costly for simple complexity), 4-Asse Machining CNC offers balanced benefits:​

1. Alta precisione: With linear tolerances as tight as ±0.01mm and rotary axis precision of ±0.005°, it produces parts that fit seamlessly—critical for gears, alberi, and medical implants.​

2. Geometrie complesse: The rotary axis enables machining of features on cylindrical or multi-sided parts (PER ESEMPIO., slots on a shaft, holes on a gear hub) that would require 2–3 setups with 3-axis systems.​

3. Tempo di configurazione ridotto: One setup handles all sides of a part—cutting setup time by 50–70% compared to 3-axis machining. Per ordini ad alto volume (PER ESEMPIO., 10,000 parti automobilistiche), this translates to faster production.​

4. Increased Efficiency: Fewer setups mean less operator time and fewer errors (PER ESEMPIO., misalignment from repositioning). Our clients report 30–40% faster production times for multi-sided parts.​

5. Versatilità: It works with all common metals and non-metals, and handles both simple (parentesi) e complesso (marcia) parts—making it a one-stop solution for diverse projects.​

6. Costo-efficacia: More affordable than 5-axis machining (lower equipment and operational costs) while offering more capability than 3-axis. Reduced setup time and errors also lower labor and material waste costs.​

7. Consistency and Repeatability: CNC programming ensures every part is identical—critical for replacement parts (PER ESEMPIO., aerospace shafts) or mass-produced components (PER ESEMPIO., brass connectors).​

Rotary Axis Benefits: The continuous rotation of the A/B axis enables high-speed machining of cylindrical parts (PER ESEMPIO., marcia) and precise indexing for multi-sided features (PER ESEMPIO., a bracket with holes on 4 lati).

Applicazioni del settore

4-Asse Machining CNC is widely used across industries that need multi-sided or cylindrical parts. Ecco le sue applicazioni più comuni:​

​

​

Per esempio, Nel settore automobilistico, our 4-axis machining produces 10,000 gear hubs monthly with consistent tooth spacing—thanks to the rotary axis’ precise indexing. In medical devices, we machine titanium implant stems with side slots (for bone screws) in one setup, ensuring patient-specific precision.

Tecniche di produzione avanzate

To maximize the potential of 4-axis systems, Usiamo all'avanguardia tecniche di lavorazione and optimized processes:​

• Fresatura: For multi-sided parts (PER ESEMPIO., parentesi), we use “indexed milling”—programming the rotary axis to stop at specific angles (PER ESEMPIO., 90°, 180°) to cut features on each side. Per parti cilindriche (PER ESEMPIO., alberi), we use “continuous milling” (rotary axis spins non-stop) to cut grooves or threads.​

Rotazione: Combined with 4-axis capabilities, turning creates complex cylindrical parts (PER ESEMPIO., alberi di ingranaggio) with both turned and milled features (PER ESEMPIO., a shaft with a turned outer diameter and milled keyway). IL rotary axis spins the part during turning, while linear axes move the turning tool to shape the circumference.​

• Drilling/Boring: For holes on cylindrical surfaces (PER ESEMPIO., a gear hub with radial holes), we use “angular drilling”—programming the rotary axis to position the part at the exact angle (PER ESEMPIO., 45°, 90°) before the Z-axis lowers the drill. This ensures holes are aligned perfectly with the part’s centerline.​

• Ottimizzazione del percorso degli strumenti: CAM software helps us create efficient paths—for example, “trochoidal milling” (for hard metals like titanium) reduces tool wear by keeping the cutting tool in constant contact with the material, while “zig-zag paths” (per alluminio) speed up cutting of large surfaces.​

• Utensili da taglio: We select tools based on material and feature type:​

• Mulini di fine in carburo: For milling steel, titanio, e compositi (durevole, resistente al calore).​

• Acciaio ad alta velocità (HSS) esercitazioni: For brass, rame, e materie plastiche (affilato, economico).​

• Indexable turning inserts: For high-volume turning (replaceable cutting edges reduce downtime).​

• Sistemi di refrigerante: We use two types of coolant for 4-axis machining:​

• Flood coolant: Per la produzione ad alto volume (covers the part and tool to reduce heat buildup).​

• Mist coolant: For precision work (PER ESEMPIO., Impianti medici) to avoid coolant residue on small features.​

• Rotary Axis Operations: We offer two key rotary modes:​

• Indexing: The rotary axis stops at fixed angles (PER ESEMPIO., 0°, 90°, 180°) to machine features on each side—ideal for multi-sided brackets.​

Continuous Rotation: The rotary axis spins non-stop (fino a 200 giri al minuto) during cutting—perfect for cylindrical parts like gears or shafts.

Casi studio: Storie di successo

Nostro 4-Asse Servizi di lavorazione CNC have helped clients across aerospace, automobile, and medical industries solve complex production challenges. Di seguito sono riportati due progetti di successo showcasing our expertise in leveraging the rotary axis for efficiency and precision:​

Caso di studio 1: Automotive Gear Hub Manufacturer​

• Sfida: Il cliente aveva bisogno 10,000 brass gear hubs monthly for electric vehicle transmissions. Each hub required a turned outer diameter, 6 radial holes (evenly spaced at 60°), and a milled keyway—all with a tolerance of ±0.01mm. Their previous supplier used 3-axis machining, which required 3 setups (rotazione, perforazione, fresatura) e causato 8% of parts to fail due to misalignment (holes not centered on the hub). Lead time was 3 settimane, which delayed their EV production.​

• Soluzione: Abbiamo usato 4-Asse Machining CNC with A-axis (rotary around X-axis) to complete the hub in one setup. Primo, we turned the outer diameter using continuous rotary rotation; Poi, we indexed the A-axis to 60° increments to drill the radial holes (ensuring perfect spacing); Finalmente, we milled the keyway by synchronizing A-axis rotation with X/Y linear movement. We used carbide turning inserts and flood coolant to handle high-volume production, e ottimizzato Percorsi degli utensili to cut each hub in 2 minuti (giù da 5 minutes with 3-axis).​

• Risultati:​

• Misalignment rate dropped from 8% to 0.5%—only 50 parts failed per month (contro. 800 previously).​

• Lead time shortened from 3 settimane a 10 days—helping the client meet their EV assembly schedule.​

• Production cost per hub decreased by 30% (reduced labor from fewer setups and faster cutting time).​

• Testimonianza del cliente: “The 4-axis machining transformed our gear hub production. One setup eliminated misalignment, and the faster speed let us keep up with EV demand. We’ve expanded our order to 15,000 hubs monthly!” — Lisa M., Automotive Production Manager.​

• Before and After: 3-axis hubs had uneven hole spacing and off-center keyways; 4-axis hubs featured perfectly aligned holes and keyways that fit seamlessly into transmissions.​

Caso di studio 2: Medical Device Company (Titanium Implant Stems)​

• Sfida: Il cliente aveva bisogno 500 patient-specific titanium orthopedic implant stems—each with a curved outer surface, 4 side slots (for bone screws), and a polished articulating end. Tolerances were tight (±0.008mm linear, ±0.005° rotary) to ensure a perfect fit in patients’ bones. The client also required FDA-compliant documentation and a lead time of 2 settimane (to meet urgent surgery schedules).​

• Soluzione: Abbiamo usato 4-Asse Machining CNC with B-axis (rotary around Y-axis) to machine each stem from a titanium blank. Primo, we imported the patient’s CT-scan-derived CAD model into CAM software, programming the B-axis to rotate the stem at 15° increments to access the curved surface and side slots. We used carbide end mills for milling (to handle titanium’s hardness) and mist coolant (to avoid residue on small slots). Dopo la lavorazione, we polished the articulating end to a Ra 0.8μm surface roughness (per medical standards) e condotto 100% Ispezione CMM (verifying linear and rotary tolerances). We also prepared detailed documentation (Parametri di lavorazione, Rapporti di ispezione) per la conformità FDA.

• Risultati:​

• 100% of implant stems met the tight tolerances and FDA requirements—no rejections.​

• Surgeons reported a 50% reduction in implant insertion time (due to precise patient-specific fit).​

• Lead time was met (2 settimane)—ensuring patients received timely surgeries.​

• Challenge Overcome: 3-axis machining would have required 4 setups for the curved surface and slots, leading to misalignment and missed deadlines. 4-axis machining’s one-setup process solved both issues.​

Testimonianza del cliente: “The 4-axis implants fit better than any we’ve used before. The precision and fast delivery have made them a staple in our orthopedic surgeries.” — Dr. James R., Orthopedic Surgeon.
