1. Pre-CNC Machining: Design Foundation for Prototypes
Перед началом Обработка с ЧПУ, a solid design stage is essential to ensure the prototype meets functional and structural requirements. This stage involves four core steps, each with clear objectives and materials.
| Этап проектирования | Ключевые требования | Рекомендуемые материалы |
| Анализ спроса на продукцию | Achieve constant temperature (40-50° C.), adjustable temperature, timing function; reserve space for heating elements, датчики, круговые платы, and battery compartments. | – |
| Структурный дизайн | Create an ergonomic curved shell to fit eye contours; design detachable enclosures (snaps/screws) for easy internal component assembly. | – |
| Выбор материала | Prototype materials should align with mass production standards. | Жилье: ABS Пластик (easy to process/dye), ПК (clear/matte), алюминиевый сплав (высокий уровень); Heating element: Thin metal sheet, electric heating film; Internal support: АБС, акрил. |
| 3D Моделирование & Рисунок | Generate 3D models with dimensional tolerances (НАПРИМЕР., shell thickness 1.5-2mm, gap 0.5mm); export STL (Для 3D -печати) or 2D files (DXF/DWG for CNC machining). | – |
2. Core CNC Machining Process for Eye Instrument Prototypes
А CNC machining process transforms design drawings into physical parts. It requires precise material preparation, step-by-step execution, and strict process control to ensure accuracy and functionality.
2.1 Материал подготовка: Выберите правильную базу
The choice of material directly affects the prototype’s performance and appearance. Below is a comparison of common materials for plastic and metal parts:
| Тип материала | Параметры | Диапазон толщины | Сценарии приложения |
| Пластиковые детали | ABS plate/rod | 1.5-3мм | Main housing (рентабельный, Легко в машине) |
| Металлические детали | Aluminum alloy plate, пластина из нержавеющей стали | Depends on design | Heat dissipation structures, декоративные детали (Высокая долговечность) |
2.2 Step-by-Step CNC Machining Execution
Follow this linear process to ensure consistent and high-quality machining:
- Программирование & Планирование пути: Используйте программное обеспечение CAM (Мастеркам, PowerMill) to generate tool paths. Set parameters like safety height, feed speed, и глубина разрезания. Use large-diameter tools (НАПРИМЕР., φ6mm flat cutters) для грубых (быстрое удаление материала) and small-diameter tools (НАПРИМЕР., φ0.5mm ball cutters) для финиша (detail preservation).
- Зажим & Позиционирование: Secure materials with a vise or vacuum cup to prevent displacement. For symmetrical structures, calibrate the center position to ensure left-right consistency.
- Обработка выполнения:
- Жилье: Mill the shape layer by layer, retaining buttons, display openings, and heat dissipation holes.
- Внутренняя структура: Mill battery compartments, circuit board slots, and heating element fixing positions.
- Поверхностная обработка: Achieve matte or glossy finishes via high-speed finishing (avoids secondary polishing).
2.3 Critical Process Control
To meet prototype standards, focus on two key controls:
- Контроль толерантности: Enclosure size tolerance is strictly controlled at ±0.1mm to ensure proper assembly with internal components.
- Temperature Simulation: For heating functions, machine grooves or thermal columns inside the enclosure to optimize heat conduction paths.
3. Пост-махинация: Поверхностная обработка & Сборка
After CNC machining, post-processing and assembly turn individual parts into a functional prototype.
3.1 Поверхностная обработка: Улучшить эстетику & Функциональность
Different part materials require specific surface treatments to improve usability and appearance:
| Тип частично | Метод лечения | Цель & Эффект |
| Пластиковые детали | Распыление | Apply matte paint (non-slip) or piano paint (high-gloss); use soothing colors (light blue, off-white). |
| Silk Screen | Print brand logos and operation icons (НАПРИМЕР., “+” “-” for temperature control) on the shell surface. | |
| Металлические детали | Anodization | Улучшить коррозионную стойкость. |
| Песчаная обработка | Enhance tactile feel. |
3.2 Component Testing & Сборка
Follow this checklist to ensure the prototype works properly:
- Функциональная проверка:
- Install analog heating plates (НАПРИМЕР., electric heating films) to test temperature control circuit response speed and temperature uniformity.
- Debug timing functions (НАПРИМЕР., 5-minute automatic shutdown); check button feel and LED indicator light transmission.
- Процесс сборки:
- Attach the circuit board, батарея, and heating element to the internal bracket; connect wires.
- Assemble the housing and cover with screws or snaps to ensure a tight seal (prevents dust entry).
4. Prototype Optimization & Итерация
Ни один прототип не идеален с первой попытки. Gather feedback and make targeted improvements to enhance performance and user experience.
| Problem Feedback | Improvement Direction |
| Housing edge chamfers are not smooth (affects touch comfort). | Optimize housing curvature to reduce eye area oppression. |
| Local overheating (poor heating efficiency). | Adjust internal air duct design to improve heat dissipation. |
| Inconvenient charging. | Add magnetic charging ports (НАПРИМЕР., Type-C) to enhance user experience. |
5. Доставка & Subsequent Applications
A well-made prototype serves multiple purposes and provides valuable data for mass production.
- Display Purposes: Use the prototype for marketing promotions, customer presentations, and appearance verification (ensures the design meets market expectations).
- Data Inheritance: Share CNC machining parameters and problem records with the mass production team to optimize injection mold design or metal die-casting processes (reduces mass production risks).
6. Common Technical Difficulties & Решения
During CNC machining and prototype production, you may encounter technical issues. Here are practical solutions:
| Technical Difficulty | Решение |
| Low accuracy when machining complex surfaces. | Use 4-axis/5-axis CNC machines with high-precision tools (НАПРИМЕР., Инструменты с алмазными покрытиями). |
| Uneven temperature control in the prototype. | Machine heat transfer grooves inside the enclosure or use thin heating plates with aluminum heat sinks. |
| Plastic housing is prone to deformation. | Choose high-strength ABS or PC materials; optimize heat treatment (НАПРИМЕР., отжиг). |
| Poor button feel. | Design silicone button pads or raised buttons; increase button travel space during CNC machining. |

Часто задаваемые вопросы
- What is the ideal temperature range for the electric heating compress eye instrument prototype, and how does CNC machining support this?
The ideal temperature range is 40-50°C. CNC machining supports this by creating precise internal grooves/thermal columns (optimizing heat conduction) and ensuring tight assembly (preventing heat loss), which helps maintain temperature uniformity.
- Can CNC machined prototypes for electric heating eye instruments be directly used for small-batch production?
В большинстве случаев, нет. CNC machined prototypes are mainly for design verification and functional testing. Для небольших партий, you need to switch to more cost-effective processes (НАПРИМЕР., injection molding for plastic parts) based on prototype data.
- How long does it take to produce a CNC machined electric heating compress eye instrument prototype?
It depends on design complexity and material type. Обычно, the process (from design finalization to prototype assembly) принимает 7-14 дни. Simple designs with plastic parts may take 5-7 дни, while complex designs with metal parts (and multiple iterations) может взять 2-3 недели.
