What is machining surface finish?

Machining surface finish is the smoothness or lack thereof of a machining operation's cutting surfaces. It can be affected by a variety of factors including tooling, material, machining conditions, and surface finish machine tools.

The goal of machining surface finish is to produce a clean, attractive, and durable surface on your parts. Poor machining surface finish can cause premature wear on your machine tools and parts, as well as decreased tool life and efficiency.

Why is machining surface finish important?

Machining surface finishes are important because they can affect the accuracy and precision of a machine’s operations. They also can affect the surface quality and durability of the part being machined. Surface finishes can be classified by their function: roughing (surface preparation), finishing (surface treatment), and honing (polishing). Roughing is typically done to remove material, finishing is used to improve surface quality, and honing is used to remove burrs or other undesirable artifacts.
