Will there be scratches on my parts?

There will inevitably be scratches left on the surface of your part after the machining process especially on the bottom side that contacts the laser bed. Thick aluminum (>.250″) may have a slight burr on the bottom edge. If you want to minimize the effect the scratches will have on the final look of your part, select deburring or tumbling before checkout if your parts are eligible.

Our deburring and tumbling services have minimum and maximum part size and material thickness limitations. Confirm which material thicknesses and part sizes are eligible here: Minimum and Maximum Part Sizes for Processing Services by Material

Linear deburring and ceramic tumbling are not finishing processes and will leave some imperfections on the surface and edges of your parts. However, they will remove major imperfections like dross and burr, and many of the scratches from the machining process. The edges of your part may be slightly rounded off during deburring, and tumbling will give your part a slightly “antiqued look.”

In Summary

Will there be scratches on my SendCutSend parts?

There will inevitably be scratches left on the surface of your part after the machining process. Thick aluminum (>.250″) may have a slight burr on the bottom edge. If you want to minimize the effect the scratches will have on the final look of your part, add deburring or tumbling before checkout if your parts are eligible.
