Company Profile
Post-Machining Essentials: Deburring and Inspection
Following the machining process, it's essential to perform
deburring on milled parts. Deburring entails
the manual removal of minor imperfections from a finished component.
These imperfections typically appear on sharp edges and result from material deformation during machining.
For instance, when a drill exits the far side of a through hole, it may leave behind blemishes that require
attention.
Subsequently, it's crucial to inspect the part's critical dimensions, especially if specific tolerances were
specified in the technical drawing. Once this inspection is complete, your part is ready for immediate use
or for any necessary post-processing.
The realm of post-processing for CNC-machined parts, whether they are milled or turned, offers numerous
avenues to explore. Therefore, we recommend enhancing your knowledge and expertise in this area to
optimize your CNC machining outcomes.
A quick guide to CNC machining parameters
Many of the crucial machining parameters are established by the machine operator during the generation
of G-code. Among the primary parameters we will discuss are the CNC machine's build size and its precision.
CNC machines are equipped with a relatively spacious build area, particularly when compared to 3D printers.
CNC milling systems are capable of machining parts with dimensions of up to 2,000 x 800 x 100 mm
(78” x 32” x 40”), while CNC turning systems excel at machining parts with diameters reaching up to
Ø 500 mm (Ø 20’’).
CNC machining empowers the creation of components with exceptional accuracy and stringent tolerances.
These machines are capable of achieving tolerances even finer than half the diameter of an average human
hair, with a precision of ± 0.025 mm or .001’’.
In cases where tolerances are not explicitly specified in the technical drawings, operators typically machine
the part with an accuracy of 0.125 mm (.005’’).
