CNC Machining(5)

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.
