What if, as a machinist, you can no longer see the process due to interfering contours? When face mills are already out of the race, and high overhangs make stable, vibration-free machining impossible? What sounds hopeless only needs the right tool – like the new MaxiMill – Tangent from CERATIZIT. This tangential indexable insert mill shows that it can take a beating, especially when machining steel and cast components.
The MaxiMill – Tangent enables stable and simultaneously soft cutting machining. The developers at CERATIZIT placed great value on a uniform chamfer profile over the entire cutting edge length of the precision-ground indexable inserts (WSP). With a wide product range of holders and WSP with four usable cutting edges in sizes -09 and -13, the tool manufacturer offers a versatile selection for different applications.
Ground WSP with stable cutting edges
The indexable inserts of the MaxiMill – Tangent are optimized for machining ISO P and ISO K materials. The maximum depth of cut for the -09 WSP is 8mm, while the larger variant is 12mm. The universal –M50 and –F50 are offered as chip guiding steps. A lower radial relief angle increases the stability of the cutting edge.
Additionally, a face cutting edge is integrated, which brings numerous advantages: It allows for uniform material removal, resulting in a smoother component surface. Furthermore, the cutting forces are distributed more evenly.
The MaxiMill – Tangent is available in three holder variants – from 25mm to 125mm: as a screw-on mill, a screw-in mill, and with a cylindrical shank. The large and stable, integrated support surfaces for the WSP provide additional stability and reliability. Another advantage of the tangential clamping: Compared to radial systems, significantly more indexable inserts can be accommodated on the milling body – maximum cutting edge density and efficiency guaranteed. And to maintain cost-effectiveness during tool changes, the WSP can be easily and quickly rotated, flipped, and replaced.
"Thanks to the super-stable construction, the powerful four-edged indexable inserts, and the tangential clamping of the MaxiMill – Tangent, components with interfering contours can now be machined easily and economically – with built-in feed turbo," says product manager Robert Frei from CERATIZIT.
Tangential to the Feed Turbo
How does the MaxiMill – Tangent perform compared to a conventional corner and face milling system? During the GGG-50 machining, it showcases its capabilities without restraint: With a holder diameter of 63mm, six cutting edges in use, a depth of cut of 2mm, and a width of cut of 35mm, a comparable competitive tool stood no chance. It managed 12 components, while the MaxiMill – Tangent was able to produce a total of 27 parts.
With internal cooling channels against chip jamming
Optimal chip control is a crucial success factor in shoulder, corner, and face milling. For this, the MaxiMill – Tangent relies on its overall construction, including the internal cooling channels. This prevents devastating chip jams, improves surface quality on the component, and significantly extends tool life.
