The Mirror Radius Milling Cutter MRX/RNM Series has earned consistent acclaim for its exceptional high precision and performance. To further enhance machining efficiency and effectively reduce tooling costs, our technical team has meticulously developed the new [High-Precision Diemaster 5G Milling Cutter Type XFG/MXF] based on specific customer process requirements. Featuring the WNHU04T3*** insert** with double-sided usability (6 cutting edges total), this H-grade precision tool incorporates wiping edges on both peripheral and end cutting edges. Combined with a high-precision tool holder, it delivers exceptional radial runout accuracy and axial runout accuracy for indexable milling cutters, enabling reliable semi-finishing and even finishing processes for diverse customer applications.
In the milling tool sector, the Mirror Radius Milling Cutter MRX/RNM Series breaks through the limitations of traditional modular milling cutters, elevating manufacturing precision to rival solid carbide end mills. Its exceptional high precision and stability have garnered widespread acclaim. The unique modular structure, coupled with precision-ground inserts and screws, ensures peripheral runout tolerance below 10μm. This series has become indispensable in demanding industries like mold manufacturing and surface finishing.
Compared to the MRX/RNM Series, the [High-Precision Diemaster 5G Milling Cutter Type XFG/MXF] offers marginally lower accuracy but excels in multi-edge efficiency. Its multi-edge design enables more cuts per cycle, significantly boosting material removal rates (MRR). Equipped with next-generation nano-composite coatings, the inserts excel in semi-finishing and finishing of hardened materials (e.g., quenched steels). Additionally, the XFG/MXF provides extended diameter options, with standard tools reaching Φ66mm, accommodating larger workpieces while optimizing cost-effectiveness.
Tool Life Testing：
The figure above compares the tool life of Φ16mm FRM-type and MXF-type cutters during peripheral wall machining. Testing parameters:
Cutting speed : 300 m/min
Feed rate (f): 0.40 mm/rev
Axial depth of cut : 0.3 mm
Radial depth of cut : 0.1 mm
Results demonstrate that the Diemaster 5G MXF milling cutter exhibits slower edge wear progression than the RNM in the final ≈100 minutes. Under identical machining durations, the MXF achieves reduced flank wear magnitude .
The figure above shows the verticality error after machining with two milling cutter types, where MXF exhibits slightly higher deviations than RNM. However, in practical applications, errors within 10μm are considered exceptional for double-sided cutters and satisfy most user requirements.
The Diemaster 5G series includes:
XFG Disc Type: Diameters Φ52mm, Φ66mm
MXF Replaceable Head Type: Diameters Φ16mm, Φ20mm, Φ25mm, Φ35mm, Φ42mm
