What Sandblasting does after CNC machining
Sandblasting is a CNC finishing step on AIHFABS. It runs after milling or turning so the blank leaves closer to a usable part — not only a machine finish. Use this page to decide whether Sandblasting matches color, wear, or assembly needs before you upload a file.
Sandblasting is a heavier blast than beads. It strips scale, rust, and deep cutter marks from steel or aluminum stock, then leaves a uniform tooth for coat or paint. Use it when the machine finish is too rough to anodize or powder as-cut.
Finishing is quoted with the machine work. Select Sandblasting in checkout, review price and lead time, and keep machining plus post-processing on one order instead of sending a raw blank to a second shop.
Why teams specify Sandblasting on CNC parts
Appearance
Sandblasting can hide cutter marks, even out color, or leave a uniform skin on housings, brackets, and review samples.
Performance
Depending on the process, Sandblasting may improve wear, corrosion resistance, or grip so the machined part survives handling and end use.
Ready-to-assemble blanks
When Sandblasting sits on the same traveler as milling or turning, the part arrives closer to install-ready — color, coat, or threads already on it.
How to order this CNC finish
Ordering Sandblasting uses the same upload as a standard CNC quote. You do not need a separate finishing RFQ for catalog options.
-
Upload the CAD file
Use STEP, STP, or another supported format. The quoter reads the stock so finishing can be priced against the actual blank.
-
Choose CNC process, material, and Sandblasting
Pick milling, turning, or another CNC route, then add Sandblasting and any other finishing the part needs.
-
Compare price, lead time, and checkout
Review options, confirm quantity, and place the order. Machining and finishing stay on one timeline and one invoice.
Compatible stock and design notes
Sandblasting is typically applied to metals — and some plastics — after CNC machining. Compatibility depends on alloy, wall thickness, and whether the surface can be reached by bath, media, or a tap. Deep pockets, thin walls, and datum faces may need a review. If the automatic quote cannot apply Sandblasting, request a manual quotation.
Need Sandblasting on a batch, a mixed set, or a part that also needs tapping or paint? Keep those options in the same quote so lead time includes the full stack.
