CNC turning materials
Post-processing and finishing options
As-machined
The most common CNC machining finish and all machining marks are visible on the material. This is the cheapest finishing option as there is no post-processing required. Roughness Average (Ra) values can be specified down to 0.2Ra in most cases.
Polished
There are various Hand polishing is chosen when high cosmetic surfaces are required. The labour intensive method means that this is one of the most expensive options although. Some areas may not be accessible to polish.
Bead blasted
Used to hide machining marks and sharp edges, creating an even texture on the outside surface of a part. Different grades of bead blasting are available, ranging from light dusting to a heavy blast that has heavy pitting by varying the bead size and blasting pressure.
Electropolishing
Electropolishing is used to create shine and smooth the outside surface of a part by leveling any peaks or burrs. Electropolishing also increases corrosion resistance and can be done on most metals. Typically suited for parts less than 1m in length.
Mirror Polishing
Mirror polishing is used to create a very high level of shine on typically large parts over 1m length. It is expensive and labour intensive.
Vibratory Polishing
Vibratory Polishing or Tumbling is used to physically polish large quantities of metal or plastic parts automatically and quickly depending on the granules or chips used (media).
Anodising
Anodising is the most popular surface treatment for Aluminium parts as it adds strength, corrosion resistance and enhances cosmetic appearance. A range of colours are available and thickness is typically 8μm-16μm depending on colour. Matte (<10GU) and Gloss levels (>20GU) can be specified also.
Hard anodising
Hard Anodising is a high-performance surface treatment for Aluminium parts as it adds strength, corrosion resistance and enhances cosmetic appearance. Black and Natural (greyish) colours are available and thickness is 35μm-50μm depending on colour. Gloss levels cannot be specified.
Plating
Plating is typically used to enhance appearance, improve corrosion resistance and improve conductivity. Typical thickness is dependant upon application but can vary from 1μm-20μm thick.
Poweder coating
Powder coating is a method of painting that improves strength, corrosion resistance and enhances cosmetic appearance. A range of colours including RAL reference codes are available. Thickness is typically 50μm-150μm. Matte (<30GU) and Gloss levels (>70GU) can be specified also.
Wet painting
Wet spray painting is often chosen to add a high cosmetic surface finish. It gives a smooth finish with varying gloss levels (>20GU) and can be highly polished with the addition of lacquer.
Chrome plating
Chrome plating increases surface hardness, cosmetic appearance by adding a think layer of chromium that is shiney, as well as providing corrosion resistance. Thickness is typically between 0.1μm-10.5μm
Nickel plating
Nickel plating increases cosmetic appearance by adding a think layer of chromium that is shiney, as well as providing additional corrosion and wear resistance. Thickness is typically between 2.5μm-150μm
CNC machining general tolerances
CNC machining general tolerances
Description
General Tolerance
Linear Dimensions
General tolerances for length, width, height, diameter, position, concentricity, symmetry are typically held to +/- 0.127mm (+/- 0.005")
Orientation and Form Dimensions
+/- 0.127mm (+/- 0.005"), Angularity 0.5 degrees. However larger parts will require specific design for manufacturing analysis
Edge Condition
Sharp edges will be broken and deburred as standard. Critical edges that must be left sharp should be annotated on the platform and an engineering drawing.
