HDF aluminum climate control door decks for doors of climate classes II+III or B+C contain a special aluminum insert as the core, which serves as a vapor barrier and also gives the aluminum climate control door a high degree of bending stiffness and dimensional stability. In the contract sector, the surfaces of the HDF top layers are often also coated with different materials. To the chagrin of carpenters and joiners, these composite panel combinations can cause high costs for the CNC machining tools used, because the HDF/aluminum composite material alone causes high wear on the carbide cutting edges usually used and consequently high repair costs for the milling tools. If an HPL laminate is then used for the surface, machining can be really expensive fun for the user.

To prevent this, Aigner-Werkzeuge GmbH from Taufkirchen an der Trattnach has developed a special milling tool for the top layer for pre-milling the wear-intensive areas. This top layer milling cutter from the Konstantin series is equipped with a special PCD interchangeable blade system in order to pre-mill the projection with the climate deck on the machining center and then finish-mill the door in a finishing operation using standardized milling tools. This also works for rebated doors with the same milling tool. To provide additional added value to the Konstantin face mill, Aigner has integrated a grooving knife section with two chamfer knives into the milling body. This allows a double bevel to be applied in the milled groove for milled-in door sealing systems such as Schallex and Kältefeind.
