Turn your multi-feature designs into high-quality parts—fast.

What Is 4-Axis CNC Machining?
4-Usinagem do eixo 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.
O Visão geral do processo é direto: A CNC (Controle numérico do computador) system interprets CAD designs to synchronize the linear axes (X/y/z, controlling the cutting tool) e o 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 “como funciona” simply: Imagine a 3-axis machine that can spin your part like a rotisserie while cutting it. Por exemplo, 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-Usinagem do eixo CNC: combining linear precision with rotational flexibility to streamline production of multi-sided parts.

The 4-Axis CNC Machining Process
Nosso processo passo a passo is optimized to leverage the rotary axis for efficiency and precision, from design to finished part:
- 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. Para protótipos, we offer free design feedback to improve manufacturability.
- Programação de came: The CAD model is imported into CAM software (MasterCam, SolidWorks CAM), where we program Caminhos da ferramenta 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.
- 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). Ferramentas de corte (Por exemplo, Mills finais, exercícios) are loaded, e coolant systems are activated to prevent overheating.
- Execução de usinagem: The CNC system runs the program, synchronizing linear (X/y/z) and rotary (A/B) movements. Por exemplo, 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.
- Post-Machining Inspection: Após a usinagem, parts undergo rigorous checks. Usamos o CMMS (Coordenar máquinas de medição) to verify linear dimensions and angular measurements (for rotary axis features). Parts with rough edges move to Deburrendo ou moagem for finishing.
Rotary Axis Integration Review: Para peças complexas, we review the rotary axis performance (Por exemplo, rotation smoothness, positioning accuracy) 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-Usinagem do eixo CNC offers balanced benefits:
- Alta precisão: With linear tolerances as tight as ±0.01mm and rotary axis precision of ±0.005°, it produces parts that fit seamlessly—critical for gears, eixos, and medical implants.
- Geometrias complexas: The rotary axis enables machining of features on cylindrical or multi-sided parts (Por exemplo, slots on a shaft, holes on a gear hub) that would require 2–3 setups with 3-axis systems.
- Tempo de configuração reduzido: One setup handles all sides of a part—cutting setup time by 50–70% compared to 3-axis machining. Para ordens de alto volume (Por exemplo, 10,000 peças automotivas), this translates to faster production.
- Increased Efficiency: Fewer setups mean less operator time and fewer errors (Por exemplo, misalignment from repositioning). Our clients report 30–40% faster production times for multi-sided parts.
- Versatilidade: It works with all common metals and non-metals, and handles both simple (Suportes) e complexo (engrenagens) parts—making it a one-stop solution for diverse projects.
- Custo-efetividade: 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.
- Consistency and Repeatability: CNC programming ensures every part is identical—critical for replacement parts (Por exemplo, aerospace shafts) or mass-produced components (Por exemplo, brass connectors).
Rotary Axis Benefits: The continuous rotation of the A/B axis enables high-speed machining of cylindrical parts (Por exemplo, engrenagens) and precise indexing for multi-sided features (Por exemplo, a bracket with holes on 4 lados).

Técnicas avançadas de fabricação
To maximize the potential of 4-axis systems, Usamos a ponta Técnicas de usinagem and optimized processes:
- Moagem: For multi-sided parts (Por exemplo, Suportes), we use “indexed milling”—programming the rotary axis to stop at specific angles (Por exemplo, 90°, 180°) to cut features on each side. Para peças cilíndricas (Por exemplo, eixos), we use “continuous milling” (rotary axis spins non-stop) to cut grooves or threads.
Virando: Combined with 4-axis capabilities, turning creates complex cylindrical parts (Por exemplo, Eixos de engrenagem) with both turned and milled features (Por exemplo, a shaft with a turned outer diameter and milled keyway). O 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 (Por exemplo, a gear hub with radial holes), we use “angular drilling”—programming the rotary axis to position the part at the exact angle (Por exemplo, 45°, 90°) before the Z-axis lowers the drill. This ensures holes are aligned perfectly with the part’s centerline.
- Otimização do caminho da ferramenta: 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” (para alumínio) speed up cutting of large surfaces.
- Ferramentas de corte: We select tools based on material and feature type:
- Mills finais de carboneto: For milling steel, titânio, e compósitos (durável, resistente ao calor).
- Aço de alta velocidade (HSS) exercícios: For brass, cobre, e plásticos (afiado, econômico).
- Indexable turning inserts: For high-volume turning (replaceable cutting edges reduce downtime).
- Sistemas de líquido de arrefecimento: We use two types of coolant for 4-axis machining:
- Flood coolant: Para produção de alto volume (covers the part and tool to reduce heat buildup).
- Mist coolant: For precision work (Por exemplo, implantes médicos) to avoid coolant residue on small features.
- Rotary Axis Operations: We offer two key rotary modes:
- Indexing: The rotary axis stops at fixed angles (Por exemplo, 0°, 90°, 180°) to machine features on each side—ideal for multi-sided brackets.
Continuous Rotation: The rotary axis spins non-stop (até 200 RPM) during cutting—perfect for cylindrical parts like gears or shafts.
Estudos de caso: Histórias de sucesso
Nosso 4-Serviços de usinagem CNC do eixo have helped clients across aerospace, Automotivo, and medical industries solve complex production challenges. Abaixo estão dois projetos de sucesso showcasing our expertise in leveraging the rotary axis for efficiency and precision:
Estudo de caso 1: Automotive Gear Hub Manufacturer
- Desafio: O cliente precisava 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 (virando, perfuração, moagem) e causado 8% of parts to fail due to misalignment (holes not centered on the hub). Lead time was 3 semanas, which delayed their EV production.
- Solução: Nós usamos 4-usinagem do eixo CNC with A-axis (rotary around X-axis) to complete the hub in one setup. Primeiro, we turned the outer diameter using continuous rotary rotation; então, 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 otimizado Caminhos da ferramenta to cut each hub in 2 minutos (de baixo de 5 minutes with 3-axis).
- Resultados:
- Misalignment rate dropped from 8% to 0.5%—only 50 parts failed per month (vs.. 800 previously).
- Lead time shortened from 3 semanas para 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).
- Depoimento do 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.
Estudo de caso 2: Medical Device Company (Titanium Implant Stems)
- Desafio: O cliente precisava 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 semanas (to meet urgent surgery schedules).
- Solução: Nós usamos 4-usinagem do eixo CNC with B-axis (rotary around Y-axis) to machine each stem from a titanium blank. Primeiro, 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). Após a usinagem, we polished the articulating end to a Ra 0.8μm surface roughness (per medical standards) e conduzido 100% Inspeção CMM (verifying linear and rotary tolerances). We also prepared detailed documentation (Parâmetros de usinagem, Relatórios de inspeção) Para conformidade da FDA.
- Resultados:
- 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 semanas)—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.
Depoimento do 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.
