Precision CNC Machining Services For Metal and Plastic Parts

Custom CNC machining manufactures parts directly from CAD files, 2D drawings, or functional specifications. Unlike catalog components, every part is made to your exact geometry, material, tolerance, and finish requirements. JADE-CNC reviews each project before quotation so the machining route, material choice, inspection scope, and delivery plan match the actual part — not a generic estimate.

This service covers prototypes, low-volume production, replacement parts, precision housings, brackets, shafts, plates, fixtures, and custom components that cannot be sourced off-the-shelf. Whether you need one functional prototype or 10,000 production parts, the same engineering review and quality process apply.

Wire EDM for precision low volume parts

EDM (Wire & Sinker)

Wire EDM for intricate profiles, sharp internal corners, and hard materials; sinker EDM for complex cavities and die work. No cutting force means burr-free, stress-free results.

surface grinding machining services

Surface Grinding

High-precision surface grinding for flatness down to 0.002mm and surface finish Ra 0.2μm. Used for sealing faces, mold surfaces, and precision datum surfaces.

CNC Machining Tolerances & Precision Capabilities

JADE-CNC routinely holds tight tolerances for critical applications. Actual achievable tolerance depends on material, part geometry, feature size, and inspection method — we review every drawing before quoting to confirm feasibility.

Different Surface Finish Types We Offer

JADE-CNC offer 30+ surface finishes in-house and through certified partners — from Anodizing to high-polish and Nickel Plating. Finish requirements are planned into the machining process to ensure correct tolerances and adhesion.

Anodizing surface finish for CNC machined parts

Anodizing

Electrochemical coating that increases corrosion resistance, wear resistance, and decorative color options. Available in Type I (chromic), Type II (sulfuric), and Type III (hard coat).

Black Oxide bracket cnc machined part

Black Oxide

Chemical conversion coating that forms a black oxide layer on steel surfaces. Provides mild corrosion resistance and a black, non-reflective appearance.

Bead blasting surface finish for CNC parts

Bead Blasting

Fine glass beads sprayed under pressure to produce a uniform matte, non-reflective surface. Hides tool marks and minor imperfections.

Chrome plating surface finish for CNC parts

Chrome Plating

Chemical conversion coating for aluminum and zinc that provides corrosion protection and improves paint adhesion. Available in clear and yellow (iridescent) finishes.

Electroplating surface finish for CNC parts

Electroplating

Deposits a thin metal layer (nickel, chrome, zinc, gold, silver, tin) onto the part surface for corrosion protection, conductivity, or decorative appearance.

Heat treating process for CNC machined parts

Heat Treating

Thermal process to alter material properties — increasing hardness, strength, or toughness. Includes annealing, quenching, tempering, and precipitation hardening.

Laser engraving for CNC machined parts

Laser Engraving

Permanent marking using a focused laser beam. Ideal for part numbers, logos, serial numbers, and scale markings. No consumables, high precision.

Passivation surface treatment for stainless steel CNC parts

Passivation

Chemical process that removes free iron from stainless steel surfaces, restoring the natural chromium oxide layer for maximum corrosion resistance.

Polishing surface finish for CNC machined parts

Polishing

Mechanical process using progressively finer abrasives to achieve a smooth, reflective surface. Ra down to 0.05μm. Available for cosmetic and sealing-face applications.

Brushing surface finish for metal parts

Brushing

Mechanical surface treatment using abrasive belts or brushes to create directional linear grain patterns. Produces a consistent brushed finish that hides scratches and tool marks.

CNC Engraving surface finish for CNC machined parts

CNC Engraving

Permanent marking machined directly into the part surface using CNC tools. Ideal for part numbers, logos, serial numbers, and scale markings.

Nickel Plating surface finish for CNC machined parts

Nickel Plating

Electroplated nickel layer that provides corrosion resistance, hardness, and a smooth, semi-bright finish. Available as electroless nickel (uniform thickness, no current required) or electrolytic nickel.

FAQ

There is no minimum order quantity at JADE-CNC. We accept orders for single prototypes, small batches, and full production runs. The same engineering review and quality process apply regardless of quantity.

We typically provide detailed quotes within 24 hours of receiving your CAD files and requirements. For complex parts or assemblies requiring additional engineering review, it may take up to 48 hours. Rush quotes are available upon request.

We accept STEP (.step/.stp), IGES (.igs/.iges), X_T (Parasolid), SolidWorks (.sldprt), and 2D PDF drawings. Please include material specifications, tolerance requirements, surface finish, and quantity with your submission.

Standard tolerances are ±0.05mm for general dimensions and ±0.01mm for critical features. With grinding and careful process control, we can hold ±0.005mm on critical bores, shafts, and sealing faces. Tolerance feasibility is reviewed before quotation based on material, geometry, and feature size.

Every order goes through incoming material inspection, first-article inspection, in-process checks, and final inspection. Critical dimensions are 100% verified; general dimensions are sampled. We use CMM, vision systems, micrometers, height gauges, surface roughness testers, and thread gauges. Inspection reports are available with every shipment.
