MZG Fillet Corner Rounding System
I am proud to present a detailed introduction to our comprehensive portfolio of Machine Clamped Fillet Milling Cutters. These tools, also known as Round Nose or Copy Mills, are the cornerstone of modern 3D and contour machining. The defining characteristic of this system is the use of strong, round indexable inserts. This geometry eliminates the weak corners found in square inserts, providing an inherently robust cutting edge that excels in complex, multi-axis toolpaths.
Excellence in Mold & Die Machining
EMRW and EMR series with high-strength circular cutting edges, perfectly suited to constantly changing engagement conditions of 3D cavity roughing and copy milling with large chip spaces.
High-Precision & Finishing Performance
R200 series delivers exceptional performance with precision-ground inserts and high-rigidity tapered body design, minimizing vibration for superior processing effects.
General-Purpose Versatility & Economic Performance
TRS and KDR series offer outstanding value with economical inserts. KDR's unique RNPJ1204 inserts provide up to 12 true cutting edges per insert for maximum economic performance.
System Performance Analysis
The performance of our Fillet Milling Cutter system is best understood through its application-specific strengths, which demonstrate a deep commitment to solving distinct manufacturing challenges. Our portfolio is meticulously engineered into two primary formats—integral shank Fillet End Mills and arbor-mounted Fillet Face Mills—to provide a targeted solution for every application, from heavy-duty mold roughing to high-precision surface finishing.
Our EMRW and EMR series are the premier choice for mold and die applications. Their performance is rooted in the high-strength circular cutting edge, which is perfectly suited to the constantly changing engagement conditions of 3D cavity roughing and copy milling. These cutters produce a superior, scalloped surface finish that requires less time in subsequent semi-finishing and finishing operations.
When the final surface quality and dimensional accuracy are critical, our R200 series delivers exceptional performance. These cutters are engineered to use precision-ground inserts, which ensures extremely tight tolerances between cutting edges. This high accuracy, combined with a high-rigidity tapered body design, minimizes vibration and produces a superior processing effect.
For shops seeking a balance of high performance and low running costs, our TRS and KDR series offer outstanding value. The KDR series performance is defined by its remarkable economy; its unique RNPJ1204 inserts can be indexed on both sides, providing up to 12 true cutting edges per insert, drastically reducing the cost-per-edge and maximizing the value of each insert.
