1. Pre-CNC Machining: Design Preparation for Electric Razor Hand Plates
Before initiating Обработка с ЧПУ for the electric razor hand plate prototype, a comprehensive design stage is critical to align with functional and user needs. This stage follows a linear process with clear focus areas, as outlined below.
Этап проектирования | Ключевые требования | Рекомендуемые материалы |
Анализ спроса на продукцию | Support high-speed tool head rotation (thousands of RPM); reserve space for motor, knife mesh, blade, battery compartment, and Type-C charging interface; ensure ergonomic non-slip grip and lightweight design. | – |
Структурный дизайн | Hand plate integration with razor body: design detachable/integrated tool head; control knife mesh-blade gap (0.1-0.2мм); reserve holes for switch, индикаторные лампы, and charging port; add internal supports for motor/circuit board stability under vibration. | – |
Выбор материала | Match mass production standards; prioritize durability, механизм, и комфорт пользователя. | Hand plate housing: ABS Пластик (легкий вес, dyeable), ПК (clear/matte), алюминиевый сплав (высокий уровень); Tool head parts: Stainless steel/nickel alloy (knife mesh), ceramic/metal (blade); Internal supports: Acrylic/ABS. |
3D Моделирование & Рисунок | Use SolidWorks/UG to create 3D models with key dimensions (НАПРИМЕР., hand plate thickness, tool head diameter, battery compartment size); export STL (3D Печать) or DXF (Обработка с ЧПУ) файлы. | – |
2. Core CNC Machining Process for Electric Razor Hand Plates
А CNC machining process transforms design blueprints into physical hand plate components. It requires strict material preparation, step-by-step execution, and precision control to meet razor performance standards.
2.1 Материал подготовка: Selecting Base Materials
Material choice directly impacts hand plate durability, масса, and machining efficiency. Ниже сравнение общих материалов:
Тип материала | Параметры | Диапазон толщины | Сценарии приложения |
Пластиковые детали | ABS sheet/rod | 2-3мм | Hand plate housing (рентабельный, Легко в машине) |
Металлические детали | Aluminum alloy sheet, Лист нержавеющей стали | 1-2мм (stainless steel for knife mesh; aluminum for high-end housings) | Tool head components (knife mesh, blade holders), high-end hand plate housings. |
2.2 Step-by-Step CNC Machining Execution
Follow this linear workflow to ensure consistent precision:
- Программирование & Планирование пути: Use Mastercam/PowerMill to generate tool paths. For hand plate housing: Use large-diameter tools (НАПРИМЕР., φ8mm flat cutters) для грубых; small-diameter tools (НАПРИМЕР., φ0.3mm ball cutters) для финиша (НАПРИМЕР., switch holes, charging port edges). For tool head parts: Set high precision (Допуск ± 0,05 мм) to ensure uniform knife mesh-blade gap.
- Зажим & Позиционирование: Secure materials with a vise/vacuum cup. For curved hand plate edges, use 4-axis/5-axis linkage machining; calibrate center position for symmetrical parts (НАПРИМЕР., dual-tool head hand plates).
- Обработка выполнения:
- Жилье: Mill outer shape, reserve switch/indicator/charging holes; add non-slip texture grooves on grip areas.
- Внутренняя структура: Mill motor mounting slots, battery compartment (with size matching Type-C interface), circuit board card slots.
- Tool Head Interface: Machine knife mesh mounting grooves (ensure flatness/verticality) and blade holder holes (НАПРИМЕР., M2 threaded holes for fixing).
- Preliminary Surface Check: Remove burrs; verify hole positions and groove depths before post-processing.
2.3 Critical Process Control
To avoid functional defects, focus on these two key controls:
- Контроль толерантности: Tool head gap tolerance ±0.02mm (prevents blade-knife mesh friction); hand plate housing size tolerance ±0.1mm (ensures component fit).
- Поверхностная плавность: For grip areas, achieve Ra 1.6μm surface roughness via finishing; avoid sharp edges (chamfer 0.5mm) to enhance comfort.
3. Пост-махинация: Поверхностная обработка & Сборка
After CNC machining, post-processing enhances aesthetics and functionality, while assembly turns parts into a usable prototype.
3.1 Поверхностная обработка: Material-Specific Processes
Different materials require tailored treatments to meet user and performance needs:
Тип частично | Метод лечения | Цель & Эффект |
Plastic Hand Plate Housing | Распыление | Apply matte paint (non-slip grip) or piano paint (high-gloss texture); common colors: черный, серебро, or custom shades. |
Silk Screen | Печать логотипов брендов, switch symbols (НАПРИМЕР., power icon), and charging indicators (НАПРИМЕР., battery level marks) on visible areas. | |
Metal Tool Head Components | Полировка (Нержавеющая сталь) | Smooth knife mesh surface (prevents skin irritation); remove machining scratches. |
Гашение & Укрепление (Blade) | Increase blade hardness (СПЧ 55-60) for long-lasting sharpness. | |
Aluminum Alloy Housing | Anodization/Sandblasting | Anodization (anti-corrosion); песчаная обработка (Мягкое прикосновение, fingerprint-resistant). |
3.2 Component Testing & Assembly Checklist
Ensure prototype functionality with this step-by-step verification and assembly process:
- Функциональная проверка:
- Install DC brushed/brushless motor; test tool head rotation speed (НАПРИМЕР., 3000-5000 Rpm) и стабильность (no abnormal vibration).
- Connect Type-C charging interface; verify LED indicator accuracy (НАПРИМЕР., red = charging, green = full).
- Test switch feel (stroke 1-1.5mm) and responsiveness (no stuck issues).
- Процесс сборки:
- Fix motor, circuit board, and battery on internal acrylic/ABS supports; secure wires with cable ties (prevent vibration damage).
- Attach knife mesh to tool head interface (ensure 0.1-0.2mm gap with blade); fix blade holder with M2 screws.
- Assemble hand plate housing and bottom cover: Use snaps (for easy disassembly) or ultrasonic welding (для водонепроницаемости); seal gaps with silicone gaskets (необязательный, for washable designs).
4. Prototype Optimization & Итерация
Based on user testing and functional feedback, optimize the hand plate prototype to resolve issues and improve usability.
Problem Feedback | Improvement Direction |
Tool head vibration during use (causes discomfort). | Add silicone shock-absorbing pads under the motor; reinforce internal support rigidity (НАПРИМЕР., add rib structures). |
Knife mesh-blade misalignment (causes uneven shaving). | Adjust CNC machining parameters for tool head grooves; use laser measurement to calibrate gap before assembly. |
Hand plate grip discomfort (slippery/heavy). | Add rubber non-slip strips on grip areas; switch to lightweight PC material (reduces weight by 10-15%). |
Charging interface damage (frequent plugging). | Design a recessed Type-C port (1-2мм глубина) or add a rubber protective cover. |
5. Common Technical Difficulties & Решения
During CNC machining and prototype production, these issues often arise—here are practical fixes:
Technical Difficulty | Решение |
Uneven knife mesh-blade gap. | Use 4-axis CNC machining for tool head grooves; пост-махинация, use a feeler gauge to adjust gap (add shims if needed). |
Motor vibration causes noise. | Optimize internal support design (НАПРИМЕР., use metal brackets instead of plastic); add foam damping pads around the motor. |
Plastic hand plate housing deformation (После обработки). | Choose fiber-reinforced ABS (increases strength by 20%); add stiffeners at edge/corner areas. |
Charging port hole misalignment (affects plug fit). | Use CNC machining with positional accuracy ±0.03mm; pre-mark hole positions on 3D models for verification. |
6. Доставка & Subsequent Applications
A well-executed hand plate prototype serves multiple purposes to support product development:
- Отображать & Тестирование: Use for marketing demos (НАПРИМЕР., trade shows), customer feedback collection (НАПРИМЕР., grip comfort surveys), and appearance validation (ensure design matches brand image).
- Data Inheritance: Share CNC machining parameters (НАПРИМЕР., пути инструментов, tolerance settings) and problem records (НАПРИМЕР., vibration solutions) with the mass production team. This optimizes injection mold design (for plastic hand plates) or metal die-casting processes (Для алюминиевых частей), reducing mass production risks.

Часто задаваемые вопросы
- What is the ideal gap between the knife mesh and blade in a CNC machined electric razor hand plate prototype, and how is this achieved via CNC machining?
The ideal gap is 0.1-0.2mm (prevents skin irritation while ensuring effective shaving). This is achieved by setting CNC machining tolerance of ±0.05mm for tool head grooves, using 4-axis machining for groove flatness, and post-machining gap verification with a feeler gauge.
- Can CNC machined electric razor hand plate prototypes be used directly for small-batch production?
Нет. CNC prototypes are for design testing and feedback collection. Для небольших партий, switch to injection molding (for plastic hand plates) or die-casting (для металлических деталей)—these processes are more cost-effective and efficient for high-volume manufacturing, using data from CNC prototypes to optimize tooling.
- How long does it take to produce a CNC machined electric razor hand plate prototype?
It depends on design complexity. For a standard hand plate (plastic housing + metal tool head interface), the process takes 5-8 дни (including design finalization, Обработка с ЧПУ, пост-обработка, и сборка). Для сложных дизайнов (НАПРИМЕР., 4-axis machined curved housings, waterproof structures), это может занять 10-12 дни.
