MCSNR/L旋削工具ホルダー｜CNMGチップ用45°M型ダブルクランプ旋盤工具

High-Stability MCSNR/L Tool Holder with 45° Lead Angle

The MCSNR/L tool holder is a specialized high-performance option among CNC turning tool holder types. Its 45-degree approach angle is specifically designed to distribute cutting pressure more evenly across the carbide edge compared to 95-degree holders. This makes the MCSNR/L a superior lathe turning tool holder for high-removal rate operations where tool longevity and stability are paramount.

Multi-Insert Compatibility: CNMG, CNMA, and CNMM

Designed for versatility, the MCSNR/L pocket is precision-machined to accommodate various CN-series inserts, allowing you to adapt to different workpiece materials:

• CNMG Inserts: The standard for versatile steel and stainless steel turning.

• CNMA Inserts: Optimal for cast iron machining, offering flat-top stability.

• CNMM Inserts: Reinforced for heavy roughing and interrupted cuts, providing extra edge strength.

Rigid M-Type Double Clamping for Heavy Cuts

To handle the intense loads of 45-degree turning, the MCSNR/L utilizes the M-type clamping mechanism. This “Multi-lock” system secures the indexable turning tool holders with both a top clamp and a center pin. This dual-locking action prevents insert rotation and lifting, outperforming standard screw-down lathe insert holders in heavy-duty and large-feed applications.

仕様表

Q: What is the main advantage of the 45-degree approach angle on the MCSNR/L?
A: The 45° angle on the MCSNR/L provides a better balance between axial and radial forces. This reduces the risk of vibration and allows for much higher feed rates compared to 95° holders. It is an excellent turning tool holder for removing large amounts of material quickly while protecting the insert’s cutting edge.

Q: Can I use the MCSNR/L for turning 90-degree shoulders?
A: No. Due to the 45-degree lead angle, this holder is not suitable for square shoulders. It is primarily used for longitudinal turning, chamfering, and roughing operations where the shoulder geometry is not a constraint.

Q: Is the M-type clamp better than the P-type for 45-degree cutting?
A: Yes. In high-feed 45-degree cutting, the insert experiences significant upward pressure. The M-type double clamp (top and center) provides more secure downward force than a P-type lever system, ensuring the CNMG holder remains stable under extreme loads.
