When developing an electric razor, the prototype phase is critical—it must validate whether the product can deliver smooth shaving, resist water damage, and fit comfortably in users’ hands. Unter allen Prototypenherstellungsmethoden, CNC -Bearbeitung stands out for its ability to handle the razor’s tiny, Hochtoleranzkomponenten (like blade meshes and motor housings)—but why is it indispensable for electric razor prototypes? This article breaks down key aspects of CNC-machined electric razor prototypes, vom Entwurf bis zum Test, to solve common R&D Herausforderungen.
1. Core Design Principles for CNC-Machined Electric Razor Prototypes
A reliable electric razor prototype starts with design optimized for CNC capabilities. Below are four non-negotiable design focuses to ensure functionality and user satisfaction:
| Designaspekt | Schlüsselanforderungen | CNC-Kompatibilitätshinweis |
| Blade-Mesh Precision | – Blade-mesh gap (0.1mm max to avoid skin irritation).- Aligned blade rotation path (no dead zones for hair). | Die CNC-Präzision von ±0,05 mm gewährleistet einen gleichmäßigen Abstand zwischen den beweglichen Schaufeln und dem statischen Netz. |
| Ergonomischer Griff | – Gebogener Griff (Anpassungen 90% von der Größe erwachsener Handflächen).- Anti-Rutsch-Muster (0.2mm Tiefe für Sicherheit vor nassen Händen). | CNC-Maschinen bearbeiten Kurven mit gleichmäßiger Krümmung (keine scharfen Kanten) und exakte Mustertiefen. |
| Wasserdichte Zuverlässigkeit | – Dichtungsnuten (für Gummi-O-Ringe, IPX7-Standard).- Geschlossener Motorraum (verhindert das Eindringen von Wasser). | CNC schneidet O-Ring-Schlitze mit einer Toleranz von ±0,02 mm, Bildet eine auslaufsichere Abdichtung für die Verwendung in der Dusche. |
| Machbarkeit der Montage | – Modulare Teile (Schneidkopf, handhaben, Batterieabdeckung).- Snap-/Thread-Schnittstellen (simulate mass-production assembly). | CNC ensures 0.1–0.3mm assembly clearances, enabling easy disassembly for maintenance tests. |
2. How Does CNC Machining Outperform Other Methods for Electric Razor Prototypes?
Compared to 3D printing or silicone duplication, CNC machining addresses unique challenges of electric razor prototypes (Z.B., blade sharpness, Wasserdichtung). Hier ist ein direkter Vergleich:
| Vorteilskategorie | CNC-Bearbeitungsleistung | 3D Druckbeschränkung | Silicone Duplication Limitation |
| Precision for Tiny Parts | Blade mesh holes (φ0.5mm) with ±0.01mm tolerance.Motor shaft slots (coaxiality <0.05mm). | Typical tolerance of ±0.1–0.5mm (risk of uneven shaving or motor jamming). | Tolerance of ±0.2–0.5mm (poor for blade-mesh alignment). |
| Material Vielseitigkeit | Prozesse Edelstahl 304 (blades/meshes), ABS (handhaben), PC (transparent covers), Und Zinklegierung (Dekorative Teile). | Beschränkt auf Kunststofffilamente (can’t replicate metal blade sharpness or rust resistance). | Only uses epoxy/resin (keine Metallverträglichkeit; zersetzt sich im Wasser). |
| Oberfläche & Functional Quality | Smooth blade edges (Ra0.4) for irritation-free shaving.Directly machines waterproof grooves (no post-processing). | Noticeable layering (erfordert Schleifen; rough surfaces cause skin friction). | Smooth but lacks detail (can’t replicate anti-slip patterns or fine mesh holes). |
| Funktionstests | Assembles full prototype (Motor + Klingen) für shaving/waterproof tests. | Needs post-drilling to fit components; not ready for direct testing. | Nur zur Kontrolle des Aussehens (no functional testing possible). |
3. Step-by-Step CNC Machining Process for Electric Razor Prototypes
Die CNC-Bearbeitung folgt einer linearen Linie, repeatable workflow to ensure prototype consistency. Der Prozess hat 7 Schlüsselphasen:
- 3D Modelldesign & Optimierung
Verwenden Sie die CAD -Software (Solidworks / und) to design parts like the cutter head and handle. Mark material (Z.B., stainless steel for blades), Präzision (± 0,05 mm), und Oberflächenbehandlung (Z.B., sandblasting for grip).
- Materialauswahl & Werkzeugvorbereitung
Wählen Sie Materialien basierend auf der Funktion:
- Blades/meshes: Edelstahl 304 (rostresistent, scharf).
- Handhaben: ABS (vielseitig, Einfach zu maschine).
Wählen Sie Werkzeuge aus: φ0.5mm drill for mesh holes; φ3mm ball nose cutter for anti-slip patterns.
- Werkzeugpfadprogrammierung
Generate G-codes for each part. Optimize paths to avoid thin-wall deformation (Z.B., layered cutting for 0.8mm-thick mesh holders).
- Spannen & Knife Setting
Fix blanks to the CNC machine (vacuum adsorption for plastics; fixtures for metals). Use laser positioning to set coordinates (ensures machining accuracy).
- Grobe Bearbeitung
Entfernen 90% of excess material with large-diameter tools, A verlassen a 0.1–0.3mm allowance zum Abschluss. Protects delicate parts like blade meshes.
- Fertig
Use high-speed cutting (10,000–15,000 rpm) to refine details:
- Klingen: Sharpen edges to Ra0.4.
- Mesh: Drill φ0.5mm holes ±0.01mm.
- Handhaben: Add anti-slip patterns (0.2MM -Tiefe) and chamfer edges (C0,5mm).
- Oberflächenbehandlung & Montageprüfung
- Oberflächenbehandlung: Polish blades (sharpness), anodize zinc alloy (Farbe), or sandblast handles (Griff).
- Montage: Fit components (Motor, Klingen, O-Ringe) into the prototype.
- Testen: Benehmen shaving tests (check hair-cutting efficiency) Und IPX7 waterproof tests (submerge in 1m water for 30 Minuten).
4. Materialauswahl & Key Testing for CNC-Machined Prototypes
Die Wahl des richtigen Materials wirkt sich direkt auf die Leistung des Prototyps aus. Below is a practical guide, plus must-perform tests:
Material Selection for Key Components
| Komponente | Empfohlenes Material | Key Performance Features |
| Blades/Meshes | Edelstahl 304 | Rostresistent, scharfe Kanten (Ra0.4) for smooth shaving. |
| Handhaben | ABS | Resistenz mit hoher Wirkung; easy to machine anti-slip patterns. |
| Transparent Covers | PC | Tragenresistent, hohe Klarheit (to view battery level). |
| Dekorative Teile | Zinklegierung | Strong die-cast feel; compatible with plating for color. |
| Waterproof Seals | ABS + Rubber O-ring | ABS rigidity + O-ring flexibility = IPX7 waterproofing. |
Must-Perform Functional Tests
| Testtyp | Zweck | Kriterien übergeben |
| Shaving Efficiency Test | Verify blade-mesh performance (avoid pulling or missed hair). | Schnitte 95% of 0.5mm hair in 1 passieren; no skin redness. |
| Wasserdichtigkeitstest | Check if sealing meets IPX7 standards. | No water ingress after 30-minute submersion. |
| Vibration Test | Ensure grip comfort (avoid excessive motor vibration). | Vibration <50db; no hand fatigue after 5 Minuten. |
| Assembly Test | Verify easy disassembly (for blade replacement). | Removes cutter head in <10 Sekunden; no stuck parts. |
5. Yigu Technology’s Perspective on CNC Machined Electric Razor Prototypes
Bei Yigu Technology, we believe CNC machining is the backbone of reliable electric razor R&D. Its ±0.05mm precision solves two core pain points: blade-mesh alignment (critical for smooth shaving) and waterproof sealing—issues 3D printing can’t fix. Zum Beispiel, a client’s prototype used CNC-machined stainless steel meshes and ABS handles: it passed IPX7 tests, cut hair with 98% Effizienz, and reduced R&Dzeit durch 25%. We recommend combining CNC (for critical parts like blades/meshes) mit 3D -Druck (for non-functional decor) to balance cost and performance. Letztlich, CNC prototypes catch design flaws early, cutting mass-production risks.
FAQ
- What’s the cost range for a CNC-machined electric razor prototype?
It ranges from 800 Zu 3,000 Yuan pro Einheit, Abhängig von der Komplexität (Z.B., 5-axis machining for curved handles costs more than 3-axis for simple parts). To reduce costs, use 3D printing for non-critical decor.
- How long does it take to make a CNC-machined electric razor prototype?
Einfache Prototypen (basic handle + Schneidkopf) Nehmen Sie sich 7–10 Tage; Komplexe Designs (with waterproof grooves + metal blades) take 12–18 days (including surface treatment and testing).
- Can CNC machining handle thin-wall parts like razor meshes?
Yes—we use layered cutting (0.1mm pro Schicht) and low cutting force (500N max) um Verformungen zu vermeiden. For 0.8mm-thick meshes, we also calibrate tool paths to ensure uniform wall thickness.
