Porte-outil MVUNR/l avec angle de 95° pour un tournage polyvalent

Aperçu

The MVUNR/L series is a high-performance external turning tool holder designed to maximize versatility in CNC profiling. Distinguished by its specific 95° entering angle, the MVUNR provides excellent clearance for facing operations while maintaining the ability to trace complex contours. This geometry effectively directs cutting forces along the axis, ensuring stable machining on various workpiece materials.

Optimisé pour les plaquettes VNMG

This holder is engineered to seat VNMG inserts (35° Diamond). The combination of the sharp 35° insert and the 95° holder geometry creates a powerful tool for semi-finishing and finishing. It allows machinists to execute facing cuts and turn square shoulders seamlessly using standard MVUNR 2525 or precise MVUNR 2020K16 sizes.

Stabilité rigide de type M

To handle the cutting forces generated at a 95° angle, the MVUNR TOOL HOLDER utilizes the robust M-Type Double Clamping System. The lock pin and top clamp firmly secure the slender VNMG insert, preventing vibration and ensuring high surface quality during deep profiling or facing cuts.

FAQ

Q1: What is the benefit of the 95° angle on the MVUNR?
A : Le 95° entering angle allows the tool to perform facing operations with better clearance than a 93° tool. It creates a -5° lead angle, which directs the cutting forces more axially, often resulting in less radial chatter on slender parts.

Q2: Can I use MVUNR 2525 for both facing and turning?
A : Yes. The MVUNR 2525 is highly versatile. Its 95° angle makes it perfect for “Facing and Turning” (pulling the tool across the face and then turning the diameter) in a single setup without changing tools.

Q3: Does it use standard VNMG inserts?
A : Yes, the MVUNR TOOL HOLDER is compatible with standard ISO VNMG inserts (like VNMG 1604). You can use the same inserts as your MVJNR or MVQNR holders, reducing inventory costs.
