CNC, or computer numerical control machining, is a subtractive manufacturing method that leverages a combination of computerized controls and machine tools to remove layers from a solid block of material. The desired cuts in the metal are programmed according to corresponding tools and machinery, which perform the machining task in an automated fashion.

Rough machining is to machine (work) approximately to size usually by taking heavy cuts with the object chiefly of removing excess metal rather than of obtaining a correct size and finish.and designed for roughing down billets, plates, castings or forgings, by hogging out large amounts of material.

The maximum size we are able to mill in a single setup is 1100mm x 650mm x 580mm. The maximum size bar stock that we are able to lathe in a single setup is 800mm x 100mm.

We specify a standard dimensional tolerance of +/-0.004" for CNC machined parts. However, it is possible to achieve a tighter tolerances up to +/-0.0002" on our lathes, 3-axis mills and 5-axis mills. If you require a tighter tolerance, please contact us.

Due to the spinning motion produced by the CNC milling machine's cutter, the surface finish of CNC machined parts will have visible toolmarks. If you require a smooth, unblemished finish to your part, we recommend choosing a secondary finish.

Surface finishing is a term that refers to the process used to alter a metal’s surface by adding, removing or reshaping. The goal is to protect the metal and improve the aesthetic side.The result depends on the metal finishing method. Often, there are a few different ways to achieve the same or similar results.

For example, metal finishing that involves a coat of paint can be done through anodizing, powder coating or wet painting. The results are similar but not the same.

• Increased corrosion resistance
• Elimination of surface defects
• Increased resistance to chemicals
• Improved conductivity and added surface electrical conduction
• Increased strength and resistance to wear while the friction effects are minimised
• Enhanced aesthetics

Clearly, surface finishing brings along some great qualities. And this list is not comprehensive, it only includes the most common reasons for applying a surface finish.

Surface finishes fall into two different categories:

Adding Processes: There are quite a few method that fall under this category. painting, powder coating, anodizing, plating, etc. are all adding processes.

Removing Processes: include Electropolishing, laser engraving, etching, grinding, blasting, brushing, Polishing, etc.

There could be processes that may seem the best option for your specific application. However, some of the most complex processes may require tools and equipment that may cause you to go over your budget. Please contact us and Make sure your decision is cost-effective.
