Centrifugal disc systems deliver very high relative velocities between media and parts, enabling efficient deburring, edge radiusing, fine grinding, and pre-polishing while maintaining geometry—ideal for flight-critical components where dimensional control and surface integrity matter.
LSI highlights: isotropic finishing • controlled edge break • Ra surface roughness • burr removal • burnishing • compound dosing • non-ferrous contamination control.

Keep a run log: media lot/shape, compound %, machine RPM, disc gap, load %, time, and resulting Ra.
These references are commonly paired with mechanical finishing to define roughness targets, cleanliness, and downstream treatment compatibility.
Typical parts: compressor hardware, brackets, housings, hinges, seat track hardware, fasteners, UAV components. Outcomes: consistent edge break, improved tribology for mating surfaces, and spec-compliant surface texture ready for inspection, coating, or anodize.

Send us sample parts—our team will run a free sample finishing and return results with a documented process window (machine, media, compound, cycle time).
Need non-Ti parts done too? We can separate media sets by alloy family to maintain cleanliness.
Because titanium is difficult to finish and the disc process delivers high energy in a short cycle. Titanium work-hardens and holds heat at the surface, so long gentle cycles can be worse than short controlled ones. A centrifugal disc machine reaches the required surface in minutes rather than hours, which limits the total heat exposure.
Heat, work hardening and feature damage. The same force that makes the cycle fast will distort thin sections, round edges that carry tolerance, and generate enough surface heat to discolour the part. Aerospace parts usually have several such features, so the process has to be validated against the drawing, not against appearance alone.
No. A shorter cycle limits heat exposure, but only if it still produces the required surface. Running a very short high-energy cycle that leaves a defect means reworking the part, which adds more heat and more risk. The cycle is set by the acceptance criteria, not by the machine capability.
Wet operation, compound dosing and contact time. The fluid carries heat away and the compound keeps the media surface working and carries fines out. A dry high-energy cycle on titanium concentrates heat and produces discoloration rather than a finish.
Only where the process has been validated on the actual part and alloy. The process removes material and rounds edges, so any feature with a tolerance is at risk. That is why a trial on representative parts with measurement before and after is the minimum requirement, not an optional extra.
Edge condition and radius, dimensional change on critical features, surface finish against the specification, and any discoloration. Record the starting condition and the full process setup, because a result cannot be compared or repeated without them.
It depends on incoming condition, media sequence, and compound control. Use B46.1 methods to measure and tune your sequence (e.g., fine ceramic → plastic → light burnish) to the drawing’s target.
Zero-gap is helpful for very fine media/small parts to prevent lodging. Our disc lineup includes adjustable-gap and zero-gap models—see the category page for options.
Dedicate media and bowls to titanium work, refresh solutions frequently, and follow ASTM B600 cleaning before inspection or downstream processing.
