Cross-hole Deburring with Nitrofreeze® Cryogenic Technology


Cross-hole deburring with Nitrofreeze® cryogenic technology removes burrs from cross-drilled holes, part features that are hard-to-reach and difficult to deburr. Our fast, safe, and cost-effective process can reach inside the most demanding geometries to remove burrs that might otherwise cause part misalignments, interfere with sealing, or clog holes through which fluids need to flow. Nitrofreeze® technology is tough on burrs, but it won’t affect a part’s geometry or surface finish.

Nitrofreeze® Cross-hole Deburring vs. Manual Deburring

Unlike hand deburring, Nitrofreeze® cryogenic deburring is an automatic process that provides consistent, repeatable, and reliable results. It uses very low temperatures and polycarbonate media to remove burrs cleanly and leaves little to no dust or residue behind. Machined parts are placed inside the chamber of a cryogenic deburring machine and then cooled to cryogenic temperatures so that the burrs become brittle. The parts are then impacted with non-abrasive polycarbonate media.

The media that Nitrofreeze® uses is sized from 0.015” (smallest) to 0.060” (largest) to accommodate specific deburring challenges. This computer-controlled process can accommodate thin-walled parts as small as 0.025” and larger, inch-based parts with greater mass. Unlike manual deburring with abrasive stones or wire brushes, Nitrofreeze® cryogenic deburring doesn’t require time-consuming secondary processes that increase labor costs, operator fatigue, and the risk of repetitive motion injuries.

Nitrofreeze® technology is also well-suited to cross-hole deburring challenges for parts with uneven surfaces, small bores, or multiple intersecting bores. When burrs are deep inside of a machined part, employees who use handheld tools may not be able to see inside the bore very easily. This can result in accidental damage to the edges of holes or the removal of too much material. Nitrofreeze® technology eliminates these risks and saves you time and money.

Nitrofreeze® Cross-hole Deburring vs. Other Deburring Methods

Because it uses non-abrasive polycarbonate media, Nitrofreeze® cryogenic deburring is also superior to vibratory or tumbling methods that may be too aggressive for some parts. Nitrofreeze® technology also provides an efficient alternative to CNC deburring, which is faster than hand deburring but still deburrs parts individually. Because Nitrofreeze® crosshole deburring is a batch process, it’s possible to deburr tens to hundreds of parts all at the same time.  

Unlike some other processes, Nitrofreeze® cryogenic deburring is safe for specialty polymers such as Delrin®, Teflon®, Tefzel®, Torlon®, and Viton®. Nitrofreeze® technology is also used with commodity plastics such ABS, PET, HDPE, PEEK, DAP, PPS, CTFE, PC, and PP. In short, it’s a great deburring tool for plastic. In addition, cryogenic deburring is used with liquid crystal polymers (LCP), precipitation hardening (PH) stainless steels, and beryllium copper.

What’s the best way to remove hard-to-reach burrs from cross-drilled holes? Contact the experts at Nitrofreeze® to review your requirements. No job is too large or too small, and our standard turnaround time is two days after receipt. If your machined part is a viable candidate for cryogenic deburring, we can perform sampling to demonstrate our process. This YouTube video shows the process in action. The consultation with Nitrofreeze® is free of charge.
