Ceratizit MaxiMill – S-Power: Tackling Cast Iron Machining Challenges with Precision and Stability
Machining cast iron often presents hurdles such as heavy tool wear, burr formation, and breakouts along workpiece edges—factors that can slow production and reduce efficiency. Ceratizit’s MaxiMill – S-Power milling cutters are engineered specifically to overcome these challenges, delivering stable, high-performance milling with reduced vibration and superior surface finish.
Featuring a high tooth count and double-sided indexable inserts, the MaxiMill – S-Power system combines efficiency with durability. Its innovative double wedge clamp design ensures quick, secure attachment of inserts, simplifying tool changes while maintaining precision.
Robert Frei, Technical Product Manager at Ceratizit, highlights:
“With the MaxiMill – S-Power, manufacturers can achieve higher feed rates thanks to the optimal 12 cutting edges on a 63mm diameter tool and positive cutting edge design. This not only enhances surface quality but also significantly reduces burr formation—benefitting industries machining braking systems or high-performance motor mounting surfaces.”
Key features include:
- High tooth count with 12 teeth (Ø63mm) enabled by an 88° setting angle, maximizing cutting edges while maintaining small chip spaces for smooth chip evacuation.
- Double-sided indexable inserts provide 8 cutting edges per insert, crafted from carefully selected substrates with advanced Dragonskin coatings for long tool life and smooth cutting.
- Robust construction: a sturdy insert seat and double wedge clamp with anti-twist protection provide secure clamping and excellent axial and radial run-out accuracy.
- Ease of maintenance: a single screw fastens each double wedge, allowing fast, accurate insert replacement. Separate clamping wedges for each holder diameter optimize clamping force.
Available in diameters from Ø56 to Ø125, the MaxiMill – S-Power is specially suited for cast iron grades GJS, GJV, and GJL. With a recommended maximum depth of cut around 8mm and feed rates between 0.08 and 0.15mm, it balances minimal breakout risk with high productivity.
The indexable inserts cover ISO P/K applications with cutting edge geometry M and come in corner radii of 0.4, 0.8, and 1.2mm. Substrate grades offered include CTPK220, CTCP230, and ceramic, allowing users to tailor performance to their specific machining requirements.
