SCZY LTD. provides 3-, 4- and 5-axis precision CNC milling services to machine complex geometries with high accuracy. Our machining team can help customers take control of their CNC milling projects to ensure that customized parts meet precise requirements.

3-axis-CNC-milling (1)

3 Axis CNC Milling

3-Axis CNC Milling moves in the X, Y and Z axes and can only mill on curved surfaces. It is suitable for manufacturing two-dimensional or simple three-dimensional parts, such as flat and simple curved parts, models, and so on.
4-axis-CNC-milling

4 Axis CNC Milling

A 4-Axis Milling machine can rotate around a fixed axis (often referred to as the A-axis or rotary axis) in addition to moving in the X, Y and Z axes. This process can be used to machine complex three-dimensional parts.
5-axis-CNC-milling

5 Axis CNC Milling

5-axis milling is capable of moving in the X, Y and Z axes and rotating around two rotary axes (A and B). Five-axis CNC mills are capable of machining more complex shapes and are suitable for high-precision part manufacturing.

What surface finishes are possible with CNC milling?

Customized parts can be surface-treated using different techniques to achieve specific surface characteristics and appearance, and we can offer a variety of surface finishing solutions for metal milled and plastic milled parts according to your needs. Examples include: anodizing, chemical nickel plating, etc.

Customized parts

Standard (As-Machined)

This finish refers to parts just after the machining process, sometimes followed by minor grinding. It contains tool marks, small burrs & chips, but provides tight tolerances. The roughness can be as low as 3.2 μm. This finish is suitable when aesthetics is not a requirement.
Customized parts

Bead Blasting

Bead blasting strikes the tiny glass, ceramic, or other beads on the machined surface at high pressure to remove tool marks, burrs, chips, and other surface irregularities. It produces a light and smoothie texture with an attractive appearance.
Customized parts

Anodized (Type II Or Type III)

The CNC-machined aluminum or non-ferrous parts can be anodized, which refers to adding and protective oxide layer on their surface. Type II is clear and color anodizing, whereas type III (MIL-A-8625/MIL-PRF-8625) refers to hard coating. Anodized surfaces resist harsh environments and save the parts from corrosion, wear, and surface degradation.
Customized parts

Powder coating

It is the electrostatic deposition of a thin powder layer(powder of epoxy, polyester, etc) and curing at high temperature, up to 400. Powder coat surfaces are highly corrosion-resistant and can be achieved in any color. It is applicable to all material-type machine parts with complex geometries.
Customized parts

Polishing

Polishing can be applied through electrochemical and mechanical methods. It produces a smooth and fine, mirror-like finish with Ra as low as 0.3 μm. This surface finish is preferred for machined parts if low-surface friction is essential for performance or aesthetics is important.
Customized parts

Black-Oxide

Black oxide is a surface treatment for ferrous materials that creates a sleek black appearance and offers mild corrosion resistance. It chemically converts the metal surface into an oxide layer, preserving tight tolerances. This finish is ideal for precision components where a low-reflective, durable surface is desired.
