Cutting Tool Expert Hartmetall Werkezuegefabrik Paul Horn GmbH Is First Manufacturer

Now listed on the APIQR´s Composite List, Germany-headquartered cutting tool expert Hartmetall Werkezuegefabrik Paul Horn GmbH is first manufacturer worldwide of turning and milling tools to achieve this distinction. So, as well as certification according to ISO 9001: 2008, Paul Horn GmbH can now refer to the internationally-recognised API standard. Tooling manufactured in conformance with API Q1 is now available from Horn Cutting Tools, Ringwood. Horn tool systems for oil industry machining applications – such as System 117 - are designed for the end machining of rotating or stationary oil field pipes up to 25" diameter. The product range currently includes tools for external and internal turning of API and special threads, internal and external chamfering, machining sealing seats, grooving, parting off and peeling. The grooving and parting off tools are based on the proven Horn S100 insert. Their working range has been expanded for the requirements of the oil industry to groove widths of 10, 12 and 16 mm and a groove depth up to 65 mm. They offer high feed rates with long engagement times, a good chipping process and reliable guidance. An ISO insert product range, available from stock, has been developed for chamfering and peeling. The high thermal resistance of the inserts enables high feed rates and the removal of thick chips which are reliably broken off, due to the geometry. Using the inserts for thread turning, pitches of 5, 8 and 10 threads per inch on internal threads and of 3, 5, 8 and 10 threads per inch on external threads can be machined. Positive clamping of the inserts in the toolholder is made using one or two bolts depending on the number of teeth. The secure seating of the 5 and 7 mm thick inserts guarantees a lateral undercut engagement that locates in similar fashion to a dovetail joint. This highly precise mounting ensures repeat positioning accuracy = 0.005 mm. A key feature is the chip breaker incorporated into the insert. As no clamping plate is required for chip forming, fewer clamping tools are needed. Heat dissipation is also improved, which manifests itself in higher precision and smoother operation as well as in a longer tool life and a more favourable price. Both the holders for the external machining as well as those for internal machining have an internal coolant supply. Source:machinery.co.uk
