Surface Finishes for CNC Machined Parts
Apart from custom CNC machining services, we also provide complete surface finishing options for precision machined parts. If you require custom finish not on this list, please do get in touch as it is likely we can source it for you.
As machined (Ra 3.2μm / Ra 126μin)
This finishing option with the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
Smooth machining (Ra 1.6μm / Ra 63μin)
Smooth machining is similar to a ‘As machined’ finish, but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.
Polishing (Ra 0.8μm / Ra 32μin or better)
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment.
Bead Blasting
Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.
Tumbled
It is a process that tumbles vibrating media on machined parts to remove sharp edges and burrs.
Tumbling can be used to remove machine marks from exterior surfaces.
Bead blasted + Anodizing type II
The parts are bead blasted to #120 grit before being anodized type II—ideal for increasing the aluminum part’s corrosion resistance and cosmetic effects.
Bead blasted + Anodized type III (Hardcoat)
The parts are bead blasted to #120 grit before being anodized type III. Type III (Hard Coat) is thicker and adds a wear-resistant layer to Type II’s corrosion resistance, suitable for functional applications.
Black Oxide
Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.
Powder Coated
This is a finish of applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods.
Chromate Conversion Coating
Chromate conversion coating is used to improve the corrosion resistance of aluminum and aluminum alloys while keeping their conductive properties. It is also applied as a base layer prior to priming and painting parts.
Plating
Include Nickel Plating, Silver Plating, Gold Plating, Zinc Plating, Chrome Plating, Tin Plating and etc, it is ideal to reduce corrosion, improve the appearance and function of solderability and electrical conductivity.

CNC Machining FAQs
Do you have a minimum order quantity?
NO! – No minimum quantity! AT Machining provides prototypes and short to medium-run production machining services.
What type of design files does AT Machining accept for quoting?
For the 3D drawing, we would prefer STEP, IGES, or X_T format. For the 2D drawing, we would prefer PDF format there are tolerances with the dimensions if possible.
How can I pay AT Machining?
AT Machining accepts payment in two ways: 1. Bank to bank wire transfer 2. PayPal
What general tolerances can AT Machining achieve?
General Machining Tolerances on metal to +/- 0.005" (+/- 0.127 mm) following ISO 2768 unless otherwise specified. Plastics and composites will be +/- 0.010”(+/- 0.254 mm).
What precision tolerances can AT Machining achieve?
Precision Machining Tolerances down to ±.0002" (0.005mm). AT can manufacture and inspect to tight tolerances per your drawing specifications.
How quickly can I get my parts?
Lead times are 2 weeks for prototypes and 3 to 4 weeks for production runs. Emergency and rush services are available.
