Match the grade to your workpiece.
Hardened steel
Send material, hardness, allowance and finish target. Distinguish continuous finishing from interrupted cutting.
Cast iron
Identify gray, chilled or high-alloy cast iron. Include scale, interruption and current wear pattern.
HSS & powder metallurgy
Confirm composition, hardness, porosity and cutting stability before choosing construction and edge preparation.
Questions about CCGW CBN inserts
What are CBN inserts?
CBN inserts use cubic boron nitride cutting material for selected hard and abrasive ferrous workpieces. Construction, binder, grade and edge preparation affect suitability.
How are CBN inserts used?
Typical applications include hard turning, cast iron machining and selected high-speed steel or powder-metallurgy operations. Review the actual material, hardness and cutting conditions first.
What materials are CBN inserts used for?
The range covers hardened steel, gray and alloy cast irons, selected high-speed steels and ferrous powder-metallurgy materials. Application suitability depends on the grade.
Are CBN inserts suitable for aluminum?
For aluminum, copper and most non-ferrous workpieces, start with our PCD insert range. Mixed-material components require separate evaluation.
How do I choose the right CBN grade?
Send material designation, hardness, finishing allowance, interruption level, speed, feed, depth of cut, coolant and required surface finish. Select Please recommend if unsure.
What is the difference between solid CBN and PCBN variants?
Construction and usable cutting edges differ. The same ISO family may have several constructions and edge counts; select the variant as well as the full insert code.
Can CBN inserts handle interrupted cutting?
Suitability depends on interruption severity, workholding, grade and edge preparation. Do not assume that a finishing grade also suits interrupted roughing.
Can Huamin Tools provide custom CBN inserts?
Send a dimensioned drawing, construction and edge requirements, material and quantity for a feasibility review.
Are all listed combinations in stock?
Specifications and grade options are catalog references. Confirm the exact model, construction, edge count, grade and drawing for availability and lead time.
