Hartverchromung

Adds a thick chromium layer to significantly boost surface hardness and durability. It’s the ideal solution for high-friction milling parts like shafts and pistons.

Vernickeln

Eine dünne, galvanisch aufgebrachte Nickelschicht, die die Verschleiß- und Korrosionsbeständigkeit erhöht. Bietet eine helle, attraktive Oberfläche für Funktionsteile.

Black Oxide

Eine chemische Behandlung, die eine dunkle, mattschwarze Oberfläche auf Stahlteilen erzeugt. Bietet eine geringe Korrosionsbeständigkeit und reduziert die Lichtreflexion.

Polierte Oberfläche

Eine glatte, glänzende Oberfläche, die durch mechanisches Polieren erzielt wird. Ideal für dekorative Teile, die erhöhten Glanz und geringe Rauheit erfordern.

Gebürstetes Finish

Eine lineare, satinartige Textur, die mit Schleifbändern oder Bürsten erzeugt wird. Sie reduziert kleinere Unebenheiten und bietet ein sauberes, dekoratives Aussehen.

Benutzerdefiniert

Benötigen Sie eine bestimmte Oberfläche? Senden Sie uns eine Anfrage, und wir werden gemeinsam mit Ihnen eine maßgeschneiderte Lösung für Ihr Projekt finden.

Company FAQ's

Häufig gestellte Fragen

Technical specifications, operational capabilities, and general inquiries regarding Yicen Precision’s manufacturing protocols.

How can I reduce CNC milling costs without hurting quality?

To keep machining cost-effective: Avoid deep pockets beyond 10× tool diameter Use standard radii compatible with tool geometry Keep wall thickness above recommended minimums Avoid unnecessarily tight tolerances Choose common materials (6061, 304, POM, etc.) Design for single-setup machining These steps reduce cycle time, tool wear, and scrap risk.

Can you support both prototypes and mass production?

Yes.

Prototyping: Fast iterations, material authenticity
Low-volume runs: Consistent quality, reduced per-unit cost
Mass production: Automated setups, multi-machine workflows, stable repeatability
CNC milling scales well from 1 unit to thousands.

What file formats do you accept?

We accept all industry-standard CAD formats:
STEP, STP, IGES, SLDPRT, Parasolid, DXF, Fusion 360.
STEP is preferred because it preserves precise surfaces and dimensions needed for accurate toolpath generation.

How long does CNC milling take?

Lead times depend on material, geometry, and quantity:

Prototypes: 1–3 days
Functional parts: 3–7 days
Finished/treated parts: 5–10 days
We also support quick-turn machining for urgent projects.

Why do CNC-milled parts sometimes warp or distort?

Warping usually results from:

Thin walls (<0.8 mm metal, <1.2 mm plastic)
Large unsupported spans
Internal material stress
Aggressive tool pressure or heat buildup
We review geometry during DFM and adjust material choice, fixturing, or toolpaths to prevent deformation.

How do you ensure machining accuracy and consistency?

Accuracy is maintained using:

CMM-Prüfung
Laser and bore measurement tools
Toolpath simulation
High-rigidity workholding
Controlled cutting parameters
GD&T-based inspection
Each batch can include FAI, CMM reports, and MTRs for traceability.

What is the difference between 3-axis, 4-axis, and 5-axis CNC milling?

3-Axis: Best for pockets, slots, simple contours.
4-Axis: Adds rotary motion for machining multiple faces in fewer setups.
5-Axis: Ideal for complex surfaces, angled features, deep cavities, aerospace/medical-grade geometries
Higher axis count = fewer setups, better accuracy, and faster cycle times.

What materials are suitable for CNC milling?

We machine a wide range of engineering-grade materials:

Metals: Aluminum (6061/7075), Stainless Steel (304/316/17-4), Brass, Copper, Steel, Tool Steel, Titanium
Plastics: POM (Delrin), Nylon, PC, PEEK, PP, PTFE, PVC, ULTEM
Material choice affects machinability, dimensional stability, tolerance capability, and surface finish.

Welche Toleranzen können Sie erreichen?

Standard CNC milling tolerances are ±0.005″ (±0.127 mm).

For precision-critical features, we can reach ±0.001″ (±0.025 mm) with stable fixturing, optimized toolpaths, and machinable materials.

Flatness/parallelism can be held to ≤ 0.002″ per 6″ depending on part size and rigidity.

What is CNC milling used for?

CNC milling is used to produce precise metal and plastic components with flat surfaces, pockets, contours, and multi-axis geometries. It’s ideal for brackets, housings, enclosures, tooling plates, heat sinks, and structural parts across aerospace, medical, automotive, robotics, and industrial equipment sectors.
