The request came with a drawing attached: a 200 mm × 100 mm × 50 mm mullite block that needed a curved profile milled through its full 50 mm thickness, with a minimum radius of 0.5 mm at the tightest transition. The customer had already tried rotary diamond grinding — the 0.5 mm radius was

A European motor manufacturer sent us two NdFeB blanks and a DXF file. The ask: cut custom contour profiles that match the drawing exactly, with no chipping and a surface finish that goes directly to grinding without rework. This is what happened. The Application — Custom NdFeB Profiles for Motor Design High-performance electric motors don’t

A carbide grinding wheel cutting Al₂O₃ at full depth of cut generates enough heat to initiate micro-cracks before the surface is even inspected. That’s not a hypothetical — it’s the failure mode we trace back to most rejected parts in precision ceramic machining. If your current process is producing dimensional drift, edge chipping, or surface

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.

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

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,
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
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,

A fused quartz glass ring. 420 mm outer diameter, 300 mm inner bore, 18 mm thick. The ring has to come out intact — one piece, no cracks, edges clean enough to go straight into grinding and polishing. At this size, that is not a given. Fused quartz is brittle. The larger the workpiece, the

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
