MAPAL offers the UNIBASE-M tool dispensing system for the optimum storage and management of tools, components and accessories. With the focus on ease of use the system is configured according to customer requirements. This applies to all the new variants in the UNIBASE-M range as well.
In many production facilities, Weldon tool holders are used as the standard chuck for solid carbide milling cutters. However, the design of this type of chuck limits its application. Indeed, the tolerances of the fit for the tool adapter are high (at a clamping diameter of 20 mm, the maximum clearance is already 22 µm). This results in a large run-out error that causes imbalance, as well as wear on one side of the tool, creating adverse effects on machining quality.
MAPAL has developed ISO indexable inserts for boring the aluminium cast combination that was successfully in use. Now the development has moved a step further due to downsizing. Together with the top half shell made of aluminium, today manufacturers increasingly rely on sintered steel instead of cast iron for the bottom half shell. This steel features a higher strength than cast iron and is therefore more suited for the increased mechanical loads.
