Вставки CBN для чугуна
PCBN inserts for grey cast iron, hard cast iron, chilled and white iron, and abrasive cast components. Select the grade and insert geometry by material structure, machining operation, interruption and required finish.
Select by Cast Iron Condition
Graphite form, matrix structure, hard phases, scale and hardness variation can change the dominant wear mechanism and the required cutting edge.
Grey Cast Iron Components
Prioritize wear resistance and process stability for abrasive grey-iron turning, bores and functional surfaces.
Hard & Abrasive Cast Iron
Review hardness, hard phases, stock allowance and impact where abrasion is the dominant tool-life limit.
Холодная и белая чугун
Check hardness variation, chilled zones and interruption before choosing the PCBN grade and edge condition.
Pearlitic Grey Cast Iron
Match the insert to matrix hardness, surface scale, machining allowance and required production consistency.
Choose by Cast Iron Machining Operation
The operation changes cutting-force direction, edge engagement and stability. Select the insert around the actual cut, not the material name alone.
Наружная токарная обработка и торцевание
Use stable geometry for diameters, faces and repeatable production where abrasive wear controls tool life.
Grey-Iron Fine Boring
Control cutting force, bore stability and finish with a suitable positive geometry, nose radius and wear-resistant grade.
Обработка седла клапана
Review seat material, profile, hardness, contact interruption and finish requirement before selecting the cutting edge.
Interrupted Cast-Iron Cuts
Prioritize edge security, toughness and setup rigidity where holes, casting voids, scale or uneven engagement increase impact.
Select a PCBN Grade for Cast Iron
The ONMY catalog identifies OBW85 and OMB90 as the primary cast-iron directions. Confirm grade availability for the selected insert code and PCBN structure.
| Класс | Материалы CBN | Catalog Direction | Применение чугуна |
|---|---|---|---|
| OBW85 | Прибл. 85% | High strength, abrasion resistance and chip resistance | Grey-iron fine boring, valve-seat machining and heavily interrupted hard or abrasive workpieces |
| OMB90 | Прибл. 90% | High strength and abrasion resistance | Common turning and milling of grey and hard cast irons |
Other catalog grades are not presented here as universal cast-iron choices. Grade and structure availability varies by insert code; confirm the final combination before ordering.
Choose the Insert Geometry for the Operation
Start from holder and component access, then check cutting-force direction, usable PCBN edge, nose radius and interruption level.
| Направление обработки | Типичные семьи | Selection Check |
|---|---|---|
| Стабильная внешняя токарная обработка | CNGA, SNGA, WNGA | Check negative geometry, nose radius, usable tips and interruption level |
| Профилирование и доступ | DNGA, VNGA | Prioritize profile access while maintaining enough cutting-edge support |
| Точное растачивание / меньшее усилие | CCGW, DCGW, TCGW, VCGW | Check positive clearance, boring-bar rigidity, overhang and finish target |
| Extended PCBN edge | Selected E / F / L structures | Use only where wider edge engagement is needed; confirm availability by insert code |
Распространенные проблемы при обработке чугуна
Use the observed failure mode to decide whether the next change should be grade, edge condition, geometry, cutting data or setup.
Быстрый абразивный износ
Review cast structure, hard phases, surface scale, cutting speed and grade wear resistance.
Сколы по краям
Check casting voids, interruption, setup rigidity, edge preparation and impact severity.
Плохая обработка поверхности
Проверьте радиус носка, подачу, вибрацию, степень износа и однородность структуры отливки.
Термический крекинг
Review coolant consistency, repeated thermal cycling, interruption and edge loading.
What to Send for a Cast Iron Insert Recommendation
A useful recommendation needs the real casting condition, operation, current insert and failure mode—not only an ISO code.
Request a Cast Iron PCBN Insert Recommendation
Share the cast iron type, operation, insert code and current process. We can review the PCBN grade, insert geometry, edge condition and quotation.
