Ductile iron consists of a mixed matrix of ferrite and pearlite, along with spheroidal or nodular graphite. Its performance is determined by the morphology, distribution of graphite, and the type of matrix . With its high strength, excellent cutting performance, wear resistance, and favorable casting properties and cost-efficiency, ductile cast iron is widely used in industries such as automotive, machinery, energy, and mold etc.
When machining ductile iron materials, the following characteristics are commonly observed:
* The hard phases in ductile iron increase machining difficulty and tool wear, leading to higher processing costs;
* Graphite nodules can fall off, and casting defects such as porosity and sand inclusions may affect machining quality and surface roughness;
* Compared to gray cast iron, ductile iron has higher strength and greater toughness, which increases cutting forces but reduces damping performance;
* High surface roughness usually requires grinding processes, which can result in high costs and low efficiency.
Worldia’s independently developed FMP-LN indexable mill, designed with high-precision manufacturing process, simplifies tool usage procedures. The insert is made of high-performance grade including PCBN, PCD, and coated carbide, and is widely applicable. It is suitable for rough to finish machining of cast iron, hardened steel, aluminum alloys, composite materials, and other hard-to-machine materials.
Pionierska precyzja: strategiczna droga Worldia w Europie Podróż Worldia od wizjonerskiego startupu w Pekinie do światowego lidera w zakresie rozwiązań narzędzi do cięcia supertwardych została podkreślona w artykule „Pionierski duch spotyka precyzję” opublikowanym przez indiamond.world. W artykule znajdują się ekskluzywne wywiady z liderami Worldia, Tao Fang i Michael Grimm, omówiające szybki wzrost firmy i jej strategiczną ekspansję w Europie, w tym otwarcie nowej spółki zależnej w Herrenberg w celu poprawy usług, skrócenia czasów realizacji i wzmocnienia relacji z klientami.

◎ The Worldia FMP-LN face milling cutter delivers high machining precision, with accuracy fully ensured by the tool’s own design and manufacturing precision. During use, the insert can be directly clamped using the insert screw without the need for adjustment, making operation simple and convenient.
@ The Worldia FMP-LN mill covers a diameter range from Ø50 to Ø250 mm. Insert grade include PCBN, PCD, and coated carbide, offering broad applicability—from roughing to finishing—on steel, aluminum alloys, cast iron, hardened steel, and difficult-to-machine materials.
◎ In this case, Worldia tailored the solution to the customer’s workpiece material and machining conditions, using a Ø160 FMP-LN face milling cutter equipped with a general-purpose PCBN insert plus a PCBN wiper insert. Compared with the original imported cermet tool solution, tool life increased by 2.3 times, and machining efficiency improved by 4.7 times. In actual performance, the Worldia solution achieved a surface roughness of Ra 0.6 after machining 10 parts, making it a viable alternative to grinding. This “milling instead of grinding” approach helped the customer reduce machining costs and improve overall efficiency.
