35+ CNC machining materials in stock, from aluminum and steel alloys to technical plastics. Each entry lists strength, weight, corrosion resistance, and typical use so you can match stock to the drawing instead of paying for a specialty alloy. Material test reports are available on request.
Aluminium delivers an exceptional strength-to-weight ratio, excellent machinability, and natural corrosion resistance. It is the ideal choice for high-performance, lightweight components in aerospace, automotive, and consumer electronics, as well as for durable parts requiring long-term outdoor exposure.
Surface treatments change how a machined part holds up and looks in service. The list below covers post-processing, coatings, and platings used to add corrosion protection, wear resistance, conductivity, or a specified cosmetic finish. Call out the treatment on your drawing and it is quoted with the part.
A chromate-based chemical conversion coating primarily for aluminum. It creates a thin, conductive layer that provides excellent corrosion resistance and serves as an ideal substrate for paint adhesion. It is a lightweight, economical alternative to anodizing, widely specified in aerospace, automotive, and military applications for corrosion protection and electrical conductivity.
A Type II anodizing process that builds a hard, transparent, and glossy oxide layer on aluminum. It significantly increases surface hardness and corrosion resistance while enhancing the metal's natural luster. Available in a wide spectrum of permanent colors, it is essential for consumer electronics, automotive trim, and architectural components demanding durability and a premium appearance.
A mechanical finishing process that propels fine media (e.g., glass beads) at high pressure to clean, texture, or matte a surface. It effectively hides minor tool marks, creates a uniform, low-glare satin finish, and provides an optimal key for subsequent painting or coating. Ideal for enclosures, handles, and parts requiring a clean, consistent, non-reflective aesthetic.
Creates a consistent, unidirectional satin grain on metal surfaces through precision abrasive brushing. This finish masks fingerprints and light scratches, offers a refined tactile feel, and reduces light reflection. It provides a premium, non-glare appearance for consumer-facing components like appliance panels, architectural hardware, and electronic bezels.
An immersion process where a charged part is coated with a paint film drawn from a water-based solution through electrophoresis. It provides exceptional, uniform coverage—including edges and recesses—with superior corrosion resistance. Primarily used as a primer or single coat for automotive frames, agricultural equipment, and high-durability industrial components.
An electrochemical process that removes a microscopic layer of material, smoothing micro-peaks and brightening the surface. Beyond achieving a brilliant, clean finish, it passivates stainless steel and other alloys, drastically improving corrosion resistance, decontamination, and cleanability. Critical for medical implants, semiconductor tools, pharmaceutical, and high-purity fluid systems.
An electroplating process that deposits a thin, adherent layer of gold onto a substrate. It provides superior corrosion resistance, excellent electrical conductivity, and a luxurious, decorative appearance. Used for high-reliability electrical connectors, RF shielding, commemorative items, jewelry, and aerospace components where performance, solderability, or aesthetics are paramount.
The surface finish directly from the CNC machine, characterized by visible, consistent tooling marks. It is the most cost-effective and fastest option, with no added processing time. Ideal for non-visible functional components, internal prototypes, and applications where minimizing cost and lead time is the highest priority over cosmetic appearance.
A chemical treatment for stainless steel that removes free iron from the surface and promotes the formation of a stable, inert chromium oxide layer. This process maximizes the alloy's natural corrosion resistance without altering part dimensions. A mandatory step for medical instruments, food processing equipment, and marine components to prevent rust and contamination.
A progressive mechanical abrasion process that refines a metal surface to a smooth, high-gloss, or mirror finish. It dramatically reduces surface roughness (Ra), improving cleanability, light reflection, reducing friction, and elevating visual appeal. Standard for luxury goods, food-grade equipment, optical components, and architectural features.
A specialized post-processing technique for thermoplastics (like ABS, PC, PMMA) that uses solvent vapors to gently melt the surface layer. This eliminates layer lines and microscopic imperfections, resulting in a crystal-clear, glossy, and smooth finish that enhances optical clarity and chemical resistance. Ideal for clear lenses, light guides, and display models.
An electrochemical process that deposits a protective zinc coating on steel or iron substrates. The zinc acts as a sacrificial anode, providing galvanic corrosion protection. It can be supplemented with various chromate conversions (clear, blue, yellow, black) for added resistance and color. A cost-effective and reliable solution for fasteners, brackets, automotive parts, and hardware.

CNC machining is essential for producing high-precision, durable components where material properties and reliability are critical. Common applications include functional prototypes, aerospace and automotive parts, medical device components, industrial machinery, and end-use production parts requiring tight tolerances and excellent surface finishes.
Strengths: dimensional accuracy, material properties unchanged from stock, repeatable results across volume runs, and a wide choice of metals and plastics. Trade-offs: a single highly complex part can cost more than 3D printing, and deep internal cavities or some undercuts cannot be machined at all.
Choose CNC machining for parts that require structural integrity, tight tolerances, or specific material properties. 3D printing is better suited for highly complex organic geometries, low-volume prototyping, and internal lattice structures. We provide analysis to recommend the optimal process for your project's performance and budget.
Standard machining holds tolerances of ±0.125mm. For high-precision projects, we routinely achieve tolerances down to ±0.025mm, supported by a full suite of inspection equipment to validate every critical dimension.
A multi-axis machining center performs milling, turning, and drilling operations in a single setup. This eliminates cumulative errors from re-fixturing, ensuring higher accuracy for complex parts through automated tool changes and synchronized axis movements.
Yes. Prior to production, our engineers perform a complimentary DFM review. We provide actionable feedback on features like wall thickness, corner radii, and thread design to optimize your part for cost-effective manufacturing, shorter lead time, and fewer defects on the first run.
We machine a broad range of metals and engineering plastics. Available finishes include anodizing, powder coating, plating, polishing, bead blasting, and more to meet aesthetic, corrosion-resistant, or wear-resistant requirements.
Pricing is calculated based on material cost, machine programming and run time, part complexity, order quantity, and selected surface finishes. We provide transparent, itemized quotes with no hidden fees.
No, we support orders of any quantity, from a single prototype to full-scale production runs, with consistent quality and no mandatory MOQ.
Standard lead time is typically 5-10 business days. Expedited services are available for urgent projects, significantly reducing turnaround time to meet critical deadlines.
The process runs First Article Inspection (FAI), in-process checks, and final validation on CMMs and optical comparators, with measured results compared to the dimensions on your drawing. Inspection reports are available on request.
