Thread milling cutter for machining leak-free tubing threads
In response to the challenges of sealing pipe joints in the oil and gas industry, Emuge has developed innovative thread milling solutions that outperform traditional tapping methods. The company now offers two advanced tools: a solid carbide thread milling cutter with spiral grooves and an indexable insert thread milling cutter with an incomplete profile. These tools are designed to handle a wide range of NPT/API threads, from 0.125′′ (3 mm) up to 20′′ (500 mm), significantly expanding the capabilities of Emuge’s Thread-Max and Threads-All series.
The solid carbide thread mill features fine-grained carbide and a TiCN coating, which enhances tool life and durability. Its multi-spiral groove design minimizes chatter during machining, ensuring smooth and precise threading. This tool is ideal for large-diameter threads, as it combines high rigidity with accurate thread profile correction, making it perfect for API pipe thread applications that require long thread lengths.
For taper thread machining, Emuge’s indexable insert thread mill is built with a hardened steel body and comes with either a CNC-ground Weldon holder or an integral CAT50 holder, available in three different rod sizes. The tool incorporates internal cooling, with coolant directed radially from the cutting edge to optimize chip evacuation and cooling, resulting in better surface finish and longer tool life. The inserts are made from fine-grained carbide and can be coated with TiN or TiAlN for enhanced performance.
Designed for heavy-duty use, the inserts feature a unique geometry that allows them to handle high chip loads while maintaining cutting efficiency. Their free-cutting shape reduces radial forces, improving accuracy and reducing tool wear. Each insert has four cutting edges, providing extended service life and cost-effective operation. Additionally, the precision-machined tool holder ensures accurate positioning of the insert on the steel end face, guaranteeing consistent and reliable results every time.
These new thread milling cutters represent a significant advancement in threading technology, offering greater flexibility, precision, and efficiency for challenging applications in the oil and gas sector. Whether you're dealing with small or large diameter threads, Emuge’s latest tools provide a reliable and high-performance solution.
