What Is CNC Mill-Turning?

Фрезерно-токарная обработка с ЧПУ—also called multi-tasking machining—is an advanced manufacturing технология that integrates both turning and milling operations into a single mill-turning center. В отличие от традиционной обработки (which requires separate lathes for turning and mills for milling, plus manual part repositioning), it lets you complete complex parts in one setup—reducing errors, сэкономить время, и улучшение последовательности.

А Обзор процесса revolves around a hybrid machine: А mill-turning center combines a rotating spindle (for turning cylindrical features) with multi-axis tool turrets (for milling flat surfaces, бурение отверстий, or adding slots). The part is held in a chuck or collet, rotated by the spindle (поворот), while tools move along linear (Х, У, Z.) and rotational (А, В) axes to add milled features—all under CNC control.​

To explain “Как это работает” simply: Imagine a machine that can first turn a metal bar into a shaft (cylindrical turning), then immediately mill a slot on its side, drill cross-holes, and add threads—all without moving the part to another machine. Например, a medical bone screw (which needs a turned cylindrical body, milled flat drive, and threaded end) can be fully machined in one run. This seamless combination of turning and milling is what makes Фрезерно-токарная обработка с ЧПУ ideal for parts with both rotational and prismatic features.

Нужно ли вам 100 titanium aerospace shafts (with milled keyways) или 50,000 brass electronics connectors (with turned bodies and milled slots), our mill-turning capabilities scale to match your project’s complexity.

The CNC Mill-Turning Process (Шаг за шагом)

Наш Пошаговый процесс is optimized to leverage the multi-tasking power of mill-turning centers, ensuring efficiency and precision from design to finish:​

1. Design and CAD Modeling: We start by reviewing your CAD model (or creating one from sketches) to identify all features—turned diameters, milled slots, отверстия, и т. д.. Our engineers optimize the design for mill-turning—e.g., ensuring milled features are accessible without spindle interference and turning diameters are compatible with chuck size. Для сложных частей, we use 3D simulation to test tool paths.​

2. CAM программирование: The CAD model is imported into CAM software (Mastercam Mill-Turn, Гиббсам) to generate integrated пути инструментов for both turning and milling. We sequence operations logically: first turning (to create the cylindrical base), then milling/drilling (to add prismatic features), and finally finishing (polishing/threading). We also program C-axis rotation (for angular milling) and live tooling activation.​

3. Setup and Calibration: The raw material (bar stock or blank) is loaded into the machine’s chuck/collet. We calibrate the spindle (for turning speed) and tool turret (for milling accuracy) using laser measuring tools. Cutting tools are loaded into the turret, и coolant systems are activated—directed to both turning and milling zones. A test part is run to verify tolerances and tool alignment.​

4. Turning Execution: The spindle rotates the part, and turning tools move along the Z (длина) and X (диаметр) axes to shape cylindrical features—OD (Внешний диаметр), ИДЕНТИФИКАТОР (inner diameter), конус, или Chamfers. For long parts, a tailstock provides additional support to prevent deflection.​

5. Milling Execution: After turning, the spindle stops rotating (or indexes to a fixed angle via C-axis), and the tool turret moves along X/Y/Z (and A/B if needed) to mill flat surfaces, слоты, карманы, or drill holes. Live tooling (rotating tools in the turret) enables drilling and tapping without repositioning.​

Post-Machining Inspection: Parts undergo rigorous Контроль качества—we measure turning dimensions (diameter/length) with micrometers, milling features (slot depth/hole position) с CMMS, and check surface finish with profilometers. Parts requiring finishing move to выслушивание или полировка.

Key Advantages of CNC Mill-Turning

Compared to traditional separate turning/milling or single-process machining, Фрезерно-токарная обработка с ЧПУ offers transformative benefits:​

1. Однократная обработка настройки: Completes all operations (поворот, фрезерование, бурение, резьба) in one setup—eliminating part repositioning errors (common in traditional machining) and reducing tolerance stack-up.​

2. Высокая точность: Achieves tolerances as tight as ±0.001mm—critical for parts like medical implants (where fit directly impacts patient safety) or aerospace sensors (where precision affects performance).​

3. Consistency and Repeatability: CNC programming ensures every part is identical—even for high-volume orders (НАПРИМЕР., 200,000 brass connectors). No variation from manual repositioning.​

4. Сложная геометрия: Handles parts with both rotational (перевернутый) and prismatic (фрезерован) features—e.g., a shaft with milled slots, a screw with a hex drive, or a valve with cross-holes.​
5. Снижение времени настройки: One setup instead of 2–3 (традиционная обработка) cuts setup time by 60–80%—speeding up production for prototypes and high-volume runs.

6. Increased Efficiency: High-speed machining (до 20,000 RPM for milling) and automated tool changers reduce per-part cycle time by 30–50% compared to traditional methods. Например, a brass connector that takes 5 minutes to make with separate turning/milling takes just 2 minutes with CNC mill-turning.​

7. Универсальность: Handles almost all materials (металлы, non-metals, exotics) and part types—from tiny medical screws (0.5мм диаметр) to large aerospace shafts (150мм диаметр). It also supports low-volume prototypes and high-volume production (200,000+ единицы/месяц).​

8. Экономическая эффективность: While mill-turning centers have higher upfront costs, reduced labor (one operator runs 2–3 machines), fewer setups, and lower scrap rates (due to fewer errors) cut long-term costs by 25–40%.​

9. Плотные допуски: The single-setup approach eliminates tolerance stack-up (errors from repositioning), enabling tighter tolerances (± 0,001 мм) than traditional machining (which often struggles with ±0.005mm for multi-feature parts).​

10. High-Quality Surface Finish: Integrated finishing operations (НАПРИМЕР., полировка, резьба) in one setup reduce tool marks and improve surface roughness (Ra down to 0.02μm)—eliminating the need for secondary finishing in many cases.

Промышленные приложения

Фрезерно-токарная обработка с ЧПУ is indispensable across industries that require complex, high-precision parts with both rotational and prismatic features. Вот его наиболее распространенные приложения:​

​

​

Например, in the energy industry, our CNC-mill-turned wind turbine gear shafts (сталь, ±0.002mm tolerance) reduce friction and extend turbine life by 20% compared to traditionally machined shafts.

Advanced Manufacturing Techniques in CNC Mill-Turning

To maximize the performance of CNC mill-turning, we leverage specialized методы обработки and optimized processes tailored to complex parts:​

9.1 Core Mill-Turning Techniques​

• Live Tooling Machining:​

The cornerstone of CNC mill-turning—live tooling (rotating tools in the turret) enables milling, бурение, and tapping while the part is held in the chuck. Например, after turning a shaft’s outer diameter, we use a live drill to add cross-holes and a live tap to create threads—all without repositioning. Мы используем:​

• Radial Live Tools: For features perpendicular to the part’s axis (НАПРИМЕР., cross-holes, слоты).​

• Axial Live Tools: For features parallel to the part’s axis (НАПРИМЕР., end-face holes, нить).​

• C-Axis Indexing/Rotation:​

The C-axis (rotational axis of the spindle) lets us position the part at precise angles (indexing) or rotate it continuously (for circular milling). Например:​

• Indexing: Rotating the part 90° to mill a slot on its side, then 180° for another slot—ensuring perfect symmetry.​

• Continuous Rotation: Rotating the part while milling to create helical features (НАПРИМЕР., spiral grooves on a turbine shaft).​

• Y-Axis Machining:​

The Y-axis (linear axis perpendicular to both X and Z) enables off-center milling—critical for parts with features not aligned to the spindle axis (НАПРИМЕР., an eccentric slot on a camshaft). It eliminates the need for specialized fixtures to offset the part.​

• Bar Feeding & Unattended Operation:​

Для масштабного производства (НАПРИМЕР., 200,000 brass connectors), Мы используем automatic bar feeders (3–6 meter capacity) to load raw material into the machine. This enables unattended operation for 8–12 hours, reducing labor costs and increasing efficiency.​

9.2 Supporting Technologies​

• Оптимизация пути инструмента:​

CAM software generates integrated пути инструментов that minimize tool travel and prioritize operations by material removal:​

1. Rough turning (removes most material quickly).​

2. Rough milling (shapes prismatic features).​

3. Finish turning (refines cylindrical surfaces).​

4. Finish milling (polishes slots/holes).​

5. Вторичные операции (резьба, выслушивание).​

For hard materials like titanium, Мы используем trochoidal milling (circular tool paths) to reduce cutting force and extend tool life.​

• Cutting Tool Selection:​

We match tools to material and operation:​

• Поворотные инструменты: Carbide inserts (TiAlN-coated for heat resistance) для металлов; diamond tools for plastics.​

• Фрезерование инструментов: Solid carbide end mills (для точности) для металлов; Высокоскоростная сталь (HSS) Конец мельницы (рентабельный) for plastics.​

• Drills/Taps: Cobalt drills for hard metals (титан, inconel); HSS taps for soft metals (латунь, алюминий).​

• Системы охлаждающей жидкости:​

Directed coolant ensures optimal performance:​

• Flood Coolant: For metal machining—high-pressure (50–80 bar) coolant directed to the cutting zone reduces heat and flushes chips.​

• Mist Coolant: For plastics/exotics—atomized coolant prevents melting/warping without residue buildup.​

• Through-Spindle Coolant: For deep-hole drilling—coolant flows through the drill’s center to reach the cutting tip, improving chip evacuation.​

• Fixture Design:​

Custom fixtures enhance stability and precision:​

• Collets: Для деталей мелкого диаметром (≤20 мм) to ensure concentricity (± 0,001 мм).​

• Chucks: For large-diameter parts (20–150mm)—3-jaw chucks for round parts, 4-jaw chucks for irregular shapes.​

Tailstocks: For long parts (≥300mm) to prevent deflection during turning/milling.

Тематические исследования: CNC Mill-Turning Success Stories

Наш CNC Mill-Turning services have solved complex part challenges for clients across aerospace and medical industries. Ниже два успешные проекты showcasing our expertise:​

Тематическое исследование 1: Aerospace Turbine Shaft Manufacturer (Titanium Shafts)​

• Испытание: Клиент нужен 500 titanium turbine shafts (80мм диаметр, 600мм длина) for jet engines—each requiring a turned outer diameter, 4 milled keyways (120° apart), 6 cross-holes (0.8мм диаметр), and a threaded end. Tolerances were ±0.002mm (critical for engine balance), and the client’s previous supplier used separate turning/milling (3 setups), вызывающий 10% of shafts to fail due to misaligned keyways. Lead time was 5 недели, delaying engine production.​

• Решение: Мы использовали 5-осевую mill-turning center with live tooling and C-axis rotation. We machined each shaft in one setup: first turning the outer diameter and threading the end, then using C-axis indexing to mill the 4 keyways (120° apart) and radial live tools to drill the cross-holes. We used carbide turning inserts (Tialn Coated) и охлаждающая жидкость высокого давления (80 бар) to handle titanium’s low machinability. Our in-line touch probe checked keyway alignment mid-production, rejecting out-of-tolerance parts immediately.​

• Результаты:​

• Misalignment rate dropped from 10% to 0.5%—only 3 shafts failed per batch (против. 50 previously).​

• Lead time shortened from 5 недели до 2 weeks—helping the client meet their engine launch deadline.​

• Production cost per shaft decreased by 35% (reduced labor from 3 setups to 1).​

• Клиентский отзыв: “The single-setup mill-turning eliminated our biggest pain—misaligned keyways. The shafts balance perfectly, and the fast delivery saved our production line. We’ve made them our exclusive supplier for turbine shafts.” — Raj P., Aerospace Engineering Director.​

• Before and After: Traditionally machined shafts had uneven keyway spacing; mill-turned shafts featured perfectly aligned keyways and cross-holes that met engine balance requirements.​

Тематическое исследование 2: Medical Device Company (Titanium Orthopedic Screws)​

• Испытание: Клиент нужен 10,000 titanium orthopedic screws monthly (5мм диаметр, 30мм длина)—each with a turned cylindrical body, milled hex drive (Для хирургических инструментов), and threaded end. Tolerances were ±0.001mm (to ensure compatibility with bone plates), and the screws required a smooth surface finish (Ra ≤ 0.1μm) Чтобы уменьшить раздражение ткани. The client’s previous supplier used separate turning/milling, ведущий к 8% of screws having mismatched hex drives and threads.​

• Решение: We used a compact mill-turning center with live tooling and C-axis indexing. We loaded titanium bar stock into an automatic bar feeder (for unattended operation) and programmed the machine to: 1) turn the screw’s body and threads; 2) index the C-axis to 60° increments to mill the hex drive; 3) polish the surface with a fine-grit live tool. We used diamond-coated milling tools for the hex drive (to ensure sharp edges) and mist coolant to prevent titanium oxidation. Пост-махинация, we inspected 100% of screws with a CMM and profilometer.​

• Результаты:​

• Скорость дефекта выпала с 8% to 0.2%—only 20 screws failed per month (против. 800 previously).​

• Surgeons reported a 40% reduction in screw insertion time (due to precise hex drive/thread alignment).​

• The client’s patient satisfaction score increased by 25% (thanks to the smooth surface finish).​

• Challenge Overcome: Separate turning/milling caused hex drives to be off-center relative to threads; CNC mill-turning’s single setup ensured perfect alignment.​

Клиентский отзыв: “These screws fit better than any we’ve used—no more struggling with misaligned hex drives. The smooth finish also means less post-surgery irritation for patients. We’ve doubled our order.” — Dr. Lisa M., Orthopedic Surgeon.
