Cutting a 300 mm Alumina Ceramic Ring: Managing Edge Chipping and Microcracks at Scale

Technical Trends / By

A 300 mm diameter alumina ceramic ring. High purity. A cutting trial for a customer in Germany. At this scale, the challenge is not just holding a tolerance — it’s preventing edge chipping and microcracks across a large, brittle workpiece where the consequences of a failed cut cannot be undone. The Application: A Trial Cut […]

Cutting a Silicon Carbide Ring with Stable Inner and Outer Geometry

Customer Stories / By

Silicon carbide seal rings end up inside pump housings, automotive water pumps, and chemical process equipment — applications where one ring failure shuts down whatever the assembly is sealing. The ring in this case measures 60 mm outer diameter, 10 mm inner bore, 10 mm thick. Small enough to look unremarkable. Hard enough that conventional

Cutting a Continuous Hexagonal Bore Through a 1-Meter Quartz Tube

Company News / By

A high-purity quartz tube, nearly one meter long. A continuous hexagonal bore that has to run straight through the entire length. A material that chips and microcracks at the slightest mechanical stress. At first glance this looks like a simple quartz tube. The hexagonal bore changes everything. Conventional internal grinding cannot reach deep into a

 Splitting an Alumina Ceramic Ring Into Two: When the Entire Cutting Allowance Is 0.4 mm

Customer Stories / By

A 10 mm thick alumina ceramic ring. A single cut. Two usable parts. This is not a standard slicing job. The geometry here is the challenge — and it’s a useful case for understanding what precision actually means when cutting advanced ceramics. The Application: One Workpiece, Two Finished Rings The customer’s objective wasn’t to cut

Hard Metal Cutting with Diamond Wire Saw — Titanium, Tungsten, and Molybdenum

Technical Trends / By

Hard metal cutting is where most conventional tools fail fast. Titanium alloys, tungsten, and molybdenum share a reputation that anyone who’s machined them knows well: they destroy tooling. Ti-6Al-4V eats carbide inserts because the heat has nowhere to go — its thermal conductivity is roughly 7 W/m·K, about one-sixth of steel. Pure tungsten is harder
