Yes, surface finishing can affect the final dimensions and tolerances of CNC machined parts. Plating and coating add material, while polishing and abrasive finishing remove material. The amount of change depends on the process, coating thickness, part geometry, and the location of critical features.
Blackening coating, also known as black oxide coating, is a chemical conversion process that forms a thin black oxide layer on carbon steel and low-alloy steel parts. Unlike deposited coatings that add a separate material layer onto the surface, black oxide converts the steel surface itself into a p...
Anodizing aluminum is an electrochemical surface treatment process that converts the outer surface of aluminum parts into a controlled aluminum oxide (Al₂O₃) layer. Unlike applied coatings that add a separate material layer, anodizing transforms the aluminum substrate itself to create a durable surf...
When industrial components face aggressive chemical exposure or severe mechanical wear, engineers rely on powder coating—a dry finishing process that utilizes electrostatic adhesion to apply free-flowing powder, which is then thermally cured to form a highly durable, cross-linked protective layer. U...
When machining complex enclosures, deep pockets, or multi-faceted housings, manufacturing engineers face a recurring trade-off: balance single-setup part precision against machine hourly rates and programming overhead. Selecting between 3-axis, 4-axis, and 5-axis CNC machining is not an arbitrary up...
