Ceratizit has released product developments and enhancements to its MaxiMill 273-08 face mill, WPC – Change Drill, as well as the HyPower Rough and HyPower Access 4.5-degree hydraulic chucks.

MaxiMill 273-08 is a series of double-sided, negative indexable octagon milling inserts with up to 16 cutting edges per insert designed for applications requiring short machining times with deeper cuts up to 6 mm. The milling cutter is said to be well-suited for automotive industry mass production where engine blocks must be milled on the cutting and mounting surfaces, for example. The MaxiMill 273-08 combines the advantages of negative indexable inserts that use both sides of the cutting edges with positive indexable inserts and their ideal installation position.

The ONKU 080608 indexable insert for the MaxiMill 273-08 is available with geometries and grades for machining steel and cast iron. The high insert thickness of the ONKU 08 (s=6.5 mm) and the large corner angle of 135 degrees improve stability and help make the system highly reliable, even with high chip removal rates and unmanned operation.

Ceratizit has also updated its WPC solid carbide drill with an exchange system. The WPC – Change Drill is designed for quick changeovers and the lowest possible material usage. Consisting of a wear-resistant steel base body, the WPC – Change enables manufacturers to replace physical vapor deposition-coated (PVD) carbide exchangeable cutting inserts clamped at the side with a clamping screw. The configuration makes changing the cutting insert quick and easy, even in the machine, without risk of incorrect assembly.

The base body of the WPC – Change features a cylindrical shank that is suitable for multiple uses with a clamping flat and through-coolant. Two face-side outlets direct coolant precisely to the cutting edge to reduce heat and tool wear. Exchangeable inserts can produce holes with diameters of 14 – 30 mm and hole depths of 3 × D and 5 × D on all machines.

The WPC – Change and matching WPC – Change UNI, suited for steel and cast-iron materials, are said to be resource-friendly and cost-effective alternatives to solid carbide drills while still delivering the same performance.

Lastly, Ceratizit’s HyPower Rough and HyPower Access 4.5-degree hydraulic chucks offer stability and precision with low radial runout and strong clamping force. Vibration damping reduces spindle load while extending tool life and providing exceptional part surface quality.

The HyPower Rough hydraulic chuck provides robust performance for roughing in dynamic milling operations. Best suited for tools using an HA shank, the chuck performs in high temperatures ranging from 80-210-degrees Celsius during long milling cycles in excess of 240 minutes. It is designed to provide process security and high chip removal.

For precision finishing, reaming and drilling applications, Ceratizit designed the HyPower Access 4.5-degree hydraulic chuck for the requirements of a wide range of markets, including tool and die production, aerospace and automotive manufacturing. Previously, only shrink-fit chucks could be used to machine certain components due to their small number of interference contours. The HyPower Access 4.5-degree chucks feature dimensions exactly matched to those of a shrink-fit chuck (DIN contour with 4.5 degrees).
