Surface Finishing Capabilities
We provide a comprehensive range of surface finishing services to improve corrosion resistance, wear performance, and visual appearance of CNC machined parts. Suitable for both functional and cosmetic requirements.
Deburring & Edge Rounding
Removes sharp edges and burrs from parts to improve safety, performance, and assembly compatibility.
Polishing
Produces smooth or mirror-like surfaces for decorative parts and reduced surface friction.
Sandblasting
Creates a uniform matte surface and removes machining marks, commonly used as a pre-treatment before anodizing or coating.
Anodizing
Enhances corrosion resistance and appearance of aluminum parts, available in clear and multiple color options.
Electroplating
Applies zinc, nickel, or other metal coatings to improve corrosion resistance and surface durability of steel components.
Conversion Coating
Provides a protective oxide layer for aluminum, enhancing corrosion resistance and paint adhesion.
Spray Coating
Applies a uniform coating to improve wear and corrosion resistance, suitable for functional and decorative finishes.
Laser Marking
Uses laser technology to engrave precise markings, serial numbers, and logos on metal or plastic surfaces.

Get a Quote → gemini@cnctal.comWhat is your minimum order quantity (MOQ)?
We specialize in both small-batch and custom CNC parts, so there is no strict MOQ. You can order prototypes or low-volume production runs.
What file formats do you accept for CNC milling orders?
We accept common CAD files such as STEP, IGES, SolidWorks, DXF, and STL. Ensure that your drawings include clear dimensions and tolerances.
How quickly can I get CNC milled parts??
Production time depends on complexity and quantity. Typically, prototypes can be completed in 2-3 days, while larger production runs may take longer.
Do you offer finishing options for CNC-milled parts?
We offer a range of finishing options, including anodising, powder coating, bead blasting, electroplating, and other surface services.
How much does CNC machining cost?
Cost depends on material, complexity, and quantity. Send your CAD files for a quote.
Should I choose 3-axis, 4-axis, or 5-axis CNC milling services?
This is usually handled by us. Simple 3-axis milling is sufficient. If more axial movement is needed to handle complex geometries and surfaces, 4-axis or 5-axis milling would be more suitable..
