What Is CNC Punching?

Штамповка с ЧПУ is an automated sheet metal fabricationтехнология that uses computer-controlled punch presses to create holes, слоты, выемки, or formed features in flat sheet materials. Unlike manual punching (which relies on human alignment and is limited to simple shapes), it uses pre-programmed tool paths to drive a punch and die set—punching precise features into sheets with minimal human intervention.

АОбзор процесса просто: A sheet of material (металл, пластик, и т. д.) is secured on a punch press table. A CNC system interprets design files to position the sheet (via X/Y linear axes) and actuate the punch— which descends into a matching die to cut or form the desired feature. Multiple tools (stored in a turret) can be swapped automatically to create diverse features in one setup.

To explain “Как это работает” simply: Imagine a digital stamping machine that can punch 100 identical holes in a steel sheet, then switch tools to add slots and notches—all without moving the sheet to another machine. Например, an aluminum HVAC vent (with dozens of air holes and mounting slots) can be fully punched in 5 минуты. This blend of automation, скорость, and precision is what makesШтамповка с ЧПУ ideal for high-volume sheet metal parts with repetitive features.

Our CNC Punching Capabilities

We offer comprehensivepunching capabilities tailored to sheet material projects, с акцентом наточные уровни, tolerance achievements, and high-speed efficiency. Below is a detailed breakdown of our key capacities:

Нужно ли вам 100 stainless steel control panels (с 50 holes each) или 5,000 acrylic display casings (with custom slots), our capabilities scale to match your project’s complexity.

The CNC Punching Process

НашПошаговый процесс is optimized to maximize efficiency and precision for sheet metal and non-metal punching:

Post-Punching Inspection: Части проходят Контроль качества—we check feature positions with calipers/CMMs, verify hole sizes with gauge pins, and inspect edges for burrs. Parts requiring finishing move to выслушивание или рисование; nested parts are separated (via shearing if needed).

Design and CAD Modeling: We start by reviewing your CAD model (or creating one from sketches) to identify all features (отверстия, слоты, и т. д.). Our engineers optimize the design for CNC punching—e.g., ensuring hole spacing meets tooling constraints and features are arranged to minimize material waste (via nesting software).

CAM программирование: The CAD model is imported into CAM software (Lantek, SolidWorks CAM) to generate пути инструментов. We program the sequence of operations: selecting tools for each feature, setting punch force (На основе толщины материала), and optimizing sheet movement (X/Y axes) to reduce cycle time. Для больших объемов, we use nesting software to fit multiple parts on one sheet.

Setup and Calibration: The sheet material is loaded into an automatic sheet feeder (для большого объема) or manually secured to the press table (для прототипов). We calibrate the punch press—setting tool offsets (to ensure feature accuracy) and testing punch force on a scrap piece of material. The turret is loaded with required tools (round punches, slot punches, и т. д.).

Punching Execution: The CNC system runs the program:

The sheet is positioned via X/Y axes to the first feature location.

The punch descends into the die to cut/form the feature (punch force adjusts automatically for material thickness).

The turret swaps tools (При необходимости) for subsequent features.

For formed features (НАПРИМЕР., embossments), a forming tool replaces the standard punch to shape the material without cutting.

Post-Punching Inspection: Части проходят Контроль качества—we check feature positions with calipers/CMMs, verify hole sizes with gauge pins, and inspect edges for burrs. Parts requiring finishing move to выслушивание или рисование; nested parts are separated (via shearing if needed).

Materials We Work With

Штамповка с ЧПУ works best with flat, ductile materials—though tool selection and punch force vary based on material hardness and thickness. Below is a breakdown of our supported materials, key properties, и идеальное использование:

We test all materials to optimize punch force, tool type, and sheet feed speed—ensuring clean cuts/forms without material damage.

В процессе: Real-time checks via vision systems (for feature position) and punch force monitors (to detect tool wear).

Key Advantages of CNC Punching

Compared to other sheet metal processes (НАПРИМЕР., лазерная резка, manual punching), Штамповка с ЧПУ предлагает уникальные преимущества:

Minimal Material Waste: Nesting software optimizes part placement on sheets, reducing waste to 5–10% (против. 15–25% for manual cutting).

Высокая точность: Achieves feature position accuracy of ±0.1mm—critical for parts that require precise assembly (НАПРИМЕР., electrical panels with connector holes).

Consistency and Repeatability: CNC programming ensures every part is identical—even for high-volume runs (НАПРИМЕР., 10,000 HVAC vents). No variation from manual alignment.

Сложная геометрия: Automatic tool changes let you create diverse features (отверстия, слоты, embossments) in one setup—eliminating the need for multiple machines.

Снижение времени настройки: Turret punch presses store up to 40 инструменты, cutting setup time by 60–80% compared to manual punching (which requires tool changes between runs).

Increased Efficiency: High-speed punching (до 600 HPM) and automated sheet feeders reduce cycle time—producing 3–5x more parts per hour than manual methods.

Универсальность: Работает с металлами, пластмассы, композиты, and acrylic—making it a one-stop solution for diverse sheet material projects.

Экономическая эффективность: Lower operational costs than laser cutting (no expensive laser tubes) and reduced labor costs (Автоматизированная операция). Для больших объемов, it’s 20–30% cheaper than other processes.

High-Quality Surface Finish: Чистый, Без норра края (≤0.05mm burr height) reduce the need for post-finishing—saving time and money.

Промышленные приложения

Штамповка с ЧПУ is widely used across industries that rely on sheet metal or flat non-metal parts. Вот его наиболее распространенные приложения:

Например, in the architectural industry, our CNC-punched aluminum facade panels (with custom slot patterns) feature consistent hole spacing (± 0,1 мм) that ensures seamless installation—critical for large-scale building projects. В электронике, our punched copper busbars (with precision holes for wiring) ensure reliable conductivity, reducing equipment failure rates.

Advanced Manufacturing Techniques in CNC Punching

To maximize efficiency, точность, and versatility in CNC Punching, we leverage specializedметоды обработки and optimized processes:

9.1 Core Punching Techniques

• Turret Punching:The most common technique—uses a rotating turret (with 10–40 tool stations) to hold different punches/dies (круглый, слот, формирование). The turret indexes to the required tool, and the punch descends to cut/form the feature. We use two turret types:
  • Stationary Turret: The turret stays fixed; the sheet moves via X/Y axes (ideal for large sheets).
  • Rotating Turret: The turret rotates to position tools; the sheet moves minimally (faster for small parts).
  • Приложение: High-volume parts with multiple features (НАПРИМЕР., HVAC vents with holes and slots).
• Nesting Optimization:Uses software (Lantek Nesting, SigmaNEST) to arrange multiple parts on a single sheet—minimizing material waste. Например, we can fit 20 small electrical boxes on a 1500×3000mm mild steel sheet (против. 15 with manual placement), уменьшение отходов от 15% к 7%. We prioritize nesting based on part quantity (high-volume parts first) and feature orientation (aligning holes to reduce tool changes).
• Формирование (Non-Cutting) Пробиться:Uses specialized forming tools (instead of cutting punches) to shape the material without removing it. Common forming operations include:
  • Тиснение: Creates raised features (НАПРИМЕР., logos on control panels).
  • Flanging: Adds a folded edge (НАПРИМЕР., mounting tabs on enclosures).
  • Louvers: Cuts and bends slits to create vents (НАПРИМЕР., heat sinks for electronics).
  • Выгода: Eliminates secondary forming operations (НАПРИМЕР., изгиб), сэкономить время.
• High-Speed Punching:Для маленького, repetitive features (НАПРИМЕР., 2mm diameter holes in circuit boards), we use high-speed punch presses (до 600 HPM) with servo-driven punches. The machine uses “gang punching” (punching multiple identical holes in one pass) and quick tool indexing to reduce cycle time.
  • Приложение: High-volume electronic components (НАПРИМЕР., copper busbars with dozens of small holes).

9.2 Supporting Technologies

Locating Pins: Ensure sheet alignment (± 0,05 мм) for repeatable feature positions.

Выбор инструмента & Обслуживание:We match tools to material and feature type:

Round Punches: HSS for soft metals/plastics; carbide for hard metals (нержавеющая сталь, high-strength alloys).

Slot/Oblong Punches: Carbide-tipped for clean edges (критически важны для деталей, требующих плотных припадков).

Формирование инструментов: Закаленная сталь (for embossing) or polyurethane (for soft forming on plastics).We maintain tools via regular sharpening (every 5,000–10,000 hits) и покрытие (TiN coating for HSS tools to extend life by 30%).

Sheet Feeding Systems:To handle high-volume production, we use automated sheet feeders:

Stack Feeders: Load sheets from a stack (до 50 sheets at a time) and feed them to the press table.

Coil Feeders: For continuous production (НАПРИМЕР., 10,000+ части/месяц)—unroll coil material (up to 300m long) and feed it to the press.

Выгода: Eliminates manual sheet loading, reducing labor costs and increasing consistency.

Coolant/Lubrication:For metal punching, we use light oil-based lubricants (applied via spray nozzles) к:

Reduce friction between punch and material (продление срока службы инструмента).

Prevent material galling (especially on stainless steel and aluminum).

Ensure clean cuts (reducing burrs).For plastics/acrylic, we use dry punching (no lubricant) to avoid residue buildup.

Fixture Design:Custom fixtures secure sheets during punching—critical for thin or flexible materials:

Вакуумные патроны: Hold thin aluminum/plastic sheets (≤1mm thick) чтобы предотвратить движение.

Clamps: Secure thick steel sheets (≥5mm thick) during high-force punching.

Тематические исследования: CNC Punching Success Stories

НашCNC Punching services have solved sheet metal challenges for clients across automotive and electronics industries. Ниже двауспешные проекты showcasing our expertise:

Тематическое исследование 1: Automotive Supplier (Mild Steel Battery Boxes)

• Испытание: Клиент нужен 10,000 mild steel battery boxes monthly for electric vehicles—each requiring 12 монтажные отверстия (8мм диаметр), 4 ventilation slots (10×50mm), and a flanged edge (for sealing). Their previous supplier used manual punching, which caused 15% of boxes to have misaligned holes (delaying assembly) и 8% waste due to poor nesting. Lead time was 3 недели, which threatened the client’s EV production schedule.
• Решение: We used a 40-station turret punch press with automated stack feeders. We optimized the design with nesting software (fitting 12 boxes per 1500×3000mm sheet, сокращение отходов 6%) and programmed the press to punch holes, cut slots, and form the flange in one setup. We used carbide punches for clean edges and light lubrication to prevent galling. In-line vision systems checked hole position (± 0,1 мм) after punching, rejecting out-of-tolerance parts immediately.
• Результаты:
  • Misalignment rate dropped from 15% to 0.5%—only 50 boxes failed per month (против. 1,500 previously).
  • Material waste decreased from 8% to 6%—saving the client $12,000 monthly in steel costs.
  • Lead time shortened from 3 недели до 10 days—helping the client meet their EV launch deadline.
  • Клиентский отзыв: “CNC punching transformed our battery box production. The consistent hole alignment eliminated assembly delays, and the nesting optimization saved us thousands. We’ve expanded our order to include other sheet metal parts.” — Mark T., Automotive Production Manager.
  • Before and After: Manual punched boxes had uneven slot widths and misaligned holes; CNC-punched boxes featured uniform slots and perfectly positioned holes that fit EV battery assemblies seamlessly.

Тематическое исследование 2: Electronics Manufacturer (Aluminum Heat Sinks)

Клиентский отзыв: “The CNC-punched heat sinks are perfect—fast, доступный, and burr-free. They’ve become our standard for all aluminum cooling components.” — Jennifer L., Electronics Component Buyer.

Испытание: Клиент нужен 5,000 aluminum heat sinks monthly for computer processors—each requiring 20 louvered vents (5×20mm) и 4 монтажные отверстия (4мм диаметр). The heat sinks required a burr-free finish (≤0.03mm burr height) to avoid damaging circuit boards, and the client needed a 2-week lead time. Their previous supplier used laser cutting, which was slow (3 minutes per heat sink) и дорого.

Решение: We used a high-speed turret punch press (400 HPM) with louver forming tools. We programmed the press to punch holes and form louvers in one setup (Время цикла: 45 seconds per heat sink) and used HSS punches (ideal for soft aluminum) with minimal lubrication. Post-punching, we used a vibratory deburring machine to remove any small burrs (ensuring ≤0.02mm burr height). We nested 25 heat sinks per 1200×2400mm aluminum sheet (напрасно тратить: 5%).

Результаты:

Production speed increased by 4x (от 3 минуты до 45 seconds per heat sink).

Cost per heat sink decreased by 35% (против. лазерная резка).

All heat sinks met the burr requirement—no circuit board damage reported.

Challenge Overcome: Laser cutting was too slow for high-volume; CNC punching’s forming tools and high speed solved both speed and cost issues.
