Smooth machining (Ra1.6µm, 63 µin)

Description

A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness (Ra) is 1.6 μm (63 μin). This can be decreased down to 0.4 μm (15.7 μin) upon request and on a case-by-case basis. Machine marks are less evident but still visible.

Design considerations for Smooth machining

Depending on the material being machined, the surface may be susceptible to corrosion or other types of damage. Applying a protective coating, such as a clear coat or wax, can help prevent damage and extend the life of the product.
When handling a product that has undergone smooth machining, it is important to handle it with care to avoid scratching or damaging the surface. Using gloves or other protective gear, and handling the product with clean, dry hands can help prevent damage.
Avoid storing the product in areas that are prone to temperature or humidity fluctuations, as this can cause warping or distortion of the surface finish.

The Justway Smooth machining process

Smooth machining, which achieves a surface finish with a roughness average (Ra) of 1.6 µm or 63 µin, offers several advantages in manufacturing processes, Let’s break down the basic steps for Smooth machining a part:

Choose the appropriate material for the product and the intended application
Clean the surface thoroughly to remove any dirt, debris, or contaminants that could affect the surface finish
Smooth out any rough patches or imperfections on the surface, using sandpaper or other smoothing tools as needed
Use a cutting tool to machine the surface to the desired smoothness and surface finish
Control machining parameters
Monitoring surface finish with a profilometer or other measuring device
Clean the surface again
