Applicable Materials

As Machined

Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.

CNC machining, Sheet metal fabrication

Metals, Plastics

Electroplating

Uses electric current to reduce dissolved metal cations to form a coherent metal coating.

CNC machining, Sheet metal fabrication

Metals

Electropolish

Electrochemical process that smoothens, polishes, and deburrs metal surfaces to a high gloss.

CNC machining

Stainless steel, Copper, Aluminum

Teflon Coating

Applies a protective layer of PTFE to reduce friction and enhance corrosion resistance.
