Steel beams and sectional steels are indispensable in many areas. Both their dimensions as well as the position and size of their bores are standardised. For this reason, the manufacturers of steel beams focus on the bore quality produced during machining, in addition to process reliability and cost-effectiveness. MAPAL offers the optimum solution with the QTD-STEEL-PYRAMID indexable insert drill with pyramid tip.
Steel beams are a prime example of successful recycling. Mainly produced from scrap metal, they’re used in the construction of halls, bridges or apartments, in mining, in the transport and logistics sector as well as in mechanical and vehicle engineering. Their job is just as important as the variety of possible applications and uses. For example, if load-bearing walls are knocked down during house renovations, steel beams are the solution to maintain the statics and replace the wall as a support.

Dimensions, masses and cross-sectional properties of steel beams and sectional steels are standardised. For the various profile shapes, it is precisely defined which static values they must meet for defined dimensions. The position and size of the pin bores are also defined. The machining of these bores is subject to challenging conditions. Generally speaking, machining conditions are usually unstable, the material thickness fluctuates and the material specification also varies.
Australian manufacturer of steel beams initiating contact with MAPAL
In one specific case in Australia, the managers at a company that manufactures steel construction materials were not satisfied with the performance of the tool produced by one of the other players on the market. The tool life of the drill fluctuated immensely. Jammed chips in particular meant that the machinist often had to replace it after just 150 bores.
The customer turned to MAPAL. The experts at the precision tool manufacturer designed a QTD-STEEL-PYRAMID indexable insert drill (QTD) with a diameter of 18 mm especially tailored to the conditions on site. The QTD was predestined for the machining of steel beams.
The pyramid tip of the QTD-STEEL-PYRAMID indexable insert drill ensures the best possible self-centering and thus a safe bore entrance.
Details about the MAPAL tool:
• QTD indexable insert drill with pyramid tip • Indexable insert made from coated solid carbide especially for steel machining • Pyramid tip for the best possible self-centring and therefore a reliable bore entrance • Shank according to ISO 9766 • Back relief for reliable chip removal • Optimum power transmission due to embedded indexable insert • Hardened steel holder with cylindrical shank • Stable Torx Plus tension • Prismatic insert seat for optimum centring of the indexable insert • Maximum performance when combined with MAPAL chucks
Standzeit deutlich verbessert, hohe Prozesssicherheit
Gearbeitet wird mit MMS sowie mit denselben Schnittdaten wie beim zuvor eingesetzten Werkzeug:
Die Ergebnisse begeistern. Mit dem MAPAL Werkzeug bearbeitet der Kunde 2.000 Bohrungen prozesssicher und wirtschaftlich.
Neben der deutlich längeren Standzeit bietet der QTD dem Hersteller von Bauträgern weitere Vorteile gegenüber dem zuvor eingesetzten Bohrer. Die Späne werden besser gebrochen. Sie sind deutlich kürzer und damit leichter abzutransportieren. Schwierigkeiten mit klemmenden Spänen gehören mit dem MAPAL Werkzeug der Vergangenheit an. Auch bei schwankender Materialstärke – im konkreten Fall liegt sie zwischen drei und zwölf Millimetern – arbeitet der QTD prozesssicher mit gleichbleibender Performance. Er erzeugt eine exzellente Bohrungsqualität mit einem gratarmen Bohrungsaustritt. Darüber hinaus ist der Schneidplattenwechsel ebenso einfach wie sicher.
Der QTD-STEEL-PYRAMID Schneidplattenbohrer mit Pyramidenspitze von MAPAL ist das optimale Werkzeug zur Bearbeitung der Bolzenbohrungen an Stahlträgern.
Das Werkzeug hat den Kunden nicht nur mit seiner Leistungsfähigkeit und dem einfachen Handling überzeugt. Sein Einsatz ist zudem überaus ressourcenschonend und wirtschaftlich. Denn das kostenintensive Hartmetall ist auf die Schneidplatte begrenzt. Und das, ohne dass der Nutzer Einbußen im Vergleich zum Pendant aus Vollhartmetall in Kauf nehmen muss.
At the automotive supplier Schabmüller, MAPAL has already been responsible for tool management. Now, the tool manufacturer from Aalen has also taken over the CAD/CAM programming of the components, including simulation.
CHIRON America upgrades standard machines to turnkey machines at its plant in Charlotte. MAPAL is the tool supplier for a machine for manufacturing truck components.
