Thanks to the special manufacturing technology carbide specialist CERATIZIT has for the first time managed to produce a high-precision prismatic insert with a positive clearance angle on both sides. The new CERATIZIT tooling system MaxiMill 273 combines the advantages of negative inserts (both sides of the cutting edges can be used) with those of positive inserts (ideal mounted position and thus low cutting forces).
Market analyses show that the majority of milling work pieces requires a material removal of less than 3.5 mm. This is where MaxiMill 273 shows its advantages very clearly: the milling system covers machining operations ranging from roughing to finishing at cutting depths up to 3.5 mm.
Maximum number of teeth for highest feedrates
The new MaxiMill 273 version 2 is characterized by a particularly close pitch with the maximum number of teeth on each diameter. It is applied in high volume production of cast iron parts, mainly in the automotive industry where for example the joint faces of motor blocks have to be milled. A special challenge in this context is the high feedrate, made possible by the large number of teeth. The new milling system however avoids the problem of edge chipping in the typically brittle cast iron components. In general the new MaxiMill 273 system helps to save costs where short machining times are required at moderate cutting depths.
A precision setting feature is also available for the close pitch system. In this way the operator may adjust the tool to within a few microns, which in fine finishing operations provides particularly smooth surfaces.
The maximum number of teeth per tool combined with easy handling and 16 fully usable cutting edges per insert are the features which specially characterize MaxiMill A273. 16 times face milling with only one insert. The Masterfinish cutting edge from CERATIZIT furthermore allows higher cutting speeds and guarantees very good work piece surfaces. All these characteristics ensure a highly efficient machining process and thus reduced production costs. In fact, the new CERATIZIT tooling system MaxiMill 273 fulfils all the important criteria for milling tools.
- Low cutting forces
- Good chip evacuation
- Clean surfaces
- Reduced costs per cutting edge
MaxiMill 273 is available in geometries and grades for the machining of steel, stainless steel and heat resistant materials as well as cast iron.
High process security
The new MaxiMill 273 milling system is provided with HyperCoat insert coating and the efficient wear protection hard & tough which guarantees consistent long tool life. High insert thickness and the large corner angle ensure optimized stability and thus reliability of the system, while stability and quality are important factors for consistent tool life without unpredictable downtime, particularly in unmanned shifts.
