Take a 100 mm cutting length and divide it into nominal 5 mm slices. With an assumed 1.0 mm kerf, the geometry allows 16 complete slices; with an assumed 0.5 mm kerf, it allows 18. That is a geometry example, not a production benchmark, but it shows why the low kerf vs wide kerf graphite […]
Low Kerf vs Wide Kerf Graphite Cutting: Which Process Costs Less? Read More »
A block of isostatic graphite is quoted, cut, and delivered as finished parts — and somewhere between the block invoice and the finished part inventory, a meaningful share of the material becomes kerf dust, trim, and offcuts. That gap is the graphite material utilization rate, and it is often invisible to procurement because the cost
Cleartran ZnS is a denser, tougher grade of zinc sulfide that requires more disciplined cutting control than standard CVD ZnS. Cut it with standard parameters and you get acceptable dimensions but elevated subsurface damage — which shows up later as scatter in the finished window. Cleartran ZnS window manufacturing done correctly delivers cut surfaces with
Thin kerf graphite slicing produces narrower cut widths than standard slicing — recovering more material per block while holding tighter dimensional tolerances across the batch. The process works well when parameters are matched to the specific graphite grade and geometry. When they aren’t, the failure modes are fast and difficult to recover: wire deviation, surface
A graphite cutting operation running at 92% single-part yield can easily drop to 70% batch yield across a 200-part production run — the difference is where most of your material cost hides. Graphite cutting yield improvement is not about improving one cut; it is about controlling the variance across every cut in a batch. This
Graphite Cutting Yield Improvement: From Kerf Control to Batch Consistency Read More »
On a 500 × 300 mm block of high-purity isotropic graphite, every additional 0.1 mm of kerf across 20 cuts translates to roughly 200 mm³ of unrecoverable material—material you already paid for, and material that shows up as scrap in your monthly cost review. In high-value grades, that is not a rounding error. It is

Graphite slicing stress is an unavoidable consequence of mechanical cutting — but it can be managed. Every time a blade or wire passes through a graphite billet, it generates mechanical forces that create residual stress in the finished wafer. Uncontrolled graphite slicing stress causes warping, microcracking, and dimensional instability that can make wafers unusable for

You can slice graphite all day long, but if the thickness varies by 0.3 mm from one plate to the next — or worse, across a single plate — your downstream process pays the price. Grinding takes longer, material gets wasted, and reject rates climb. Graphite slicing thickness control is the single most important quality
Graphite Slicing Thickness Control: Achieving Consistent Plates Every Time Read More »
Graphite electrode cutting quality determines more than dimensional accuracy — it sets the performance ceiling for every downstream process, from EDM discharge stability to mold surface finish and production yield. Defects introduced during cutting do not stay in the electrode: they cascade through the manufacturing chain and compound at each stage. This is the final
Graphite electrode surface quality is not a finishing concern — it is a cutting outcome. By the time an electrode reaches the EDM machine, its surface state has already been set by the cutting process that produced the blank. Finishing operations can refine what cutting delivers, but they cannot fundamentally reverse damage that originates at
