Economical and reliable machining of steel beams
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.
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.
Details about the MAPAL tool:
• 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
Tool life multiplied, high process reliability
Work is carried out with MQL and with the same cutting values as the previously used tool:
Cutting speed: 63 m/min | Spindle speed: 1,115 rpm | Feed: 0.3 mm
The results are exciting. With the MAPAL tool, the customer is now able to machine a whole 2,000 bores reliably and economically.
