GFRP Diamond Wire Cutting: Zero Delamination on a 50mm Blank

Technical Trends / By

GFRP diamond wire cutting solved a difficult production problem on a 50mm-thick glass fiber reinforced plastic blank: achieving clean through-cuts with no exit-edge delamination, no frayed fibers, and no glass fiber dust entering the work environment. The first batch was cut with a conventional carbide-tipped band saw. Delamination appeared on most of the thick sections. […]

Cutting an Aerospace PMI Foam Profile: SH60-60, 0.65 mm Wire, 150 N Tension

Technical Trends / By

An aerospace-grade PMI foam workpiece. A programmed curved contour. One continuous diamond wire cut on the SH60-60 with a 0.65 mm wire loop at 150 N tension and 30 m/s wire speed. In this application, the geometry is the challenge — not just the material. Most PMI cutting content online talks about flat slabs and

Cutting a Pre-Sintered Alumina Ceramic Blank Before Final Sintering: Ø480 mm, Dry Cut, Low Chipping

Technical Trends / By

A Ø480 mm pre-sintered alumina ceramic blank. The goal: cut it before final sintering to reduce machining allowance and downstream processing cost. The constraint: the material is fragile at this stage — too much cutting force causes edge cracking or workpiece fracture. This case describes how we approached the cut, why dry cutting was required,

Cutting a High-Purity Graphite Susceptor Ring: Multiple Precision Slots, Zero Edge Chipping

Technical Trends / By

A large-diameter graphite ring. Multiple precision slots. Dry-cut at 40–70 m/s — and every slot wall has to come out clean. Graphite cuts fast. That’s not the problem. The problem is that graphite also fractures fast, and on a large cylindrical ring with multiple slots, each cut pass is another opportunity for a crack to

Garnet Crystal Cutting Machine: Diamond Wire Saw Solutions for YIG and GGG Optics

Technical Trends / By

If you are cutting YIG or GGG garnet for Faraday rotators, the machine you need is a diamond wire saw — specifically one with closed-loop wire tension control and a precision orientation fixture. Standard slicing saws produce too much kerf loss and too much subsurface damage for optical-grade garnet. This page covers which machines work,

Diamond Wire Cutting High Value Brittle Materials: Germanium, ZnSe, and Functional Crystals

Technical Trends / By

Diamond wire cutting high value brittle materials requires a fundamentally different approach from cutting structural metals or standard optical glass. When you are cutting a block of germanium worth several thousand dollars, the cost of a single bad cut is not a process inefficiency — it is a financial event. The material cannot be re-melted

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
