The MCGNR is a standardized, clamp-style tool holder for external turning. It is part of the ISO 5608 system for indexable tooling, where the alphanumeric code defines its key characteristics:
M - Toolholder style (Specific geometry for external turning)
C - Lead angle (95°)
G - Toolholder size and insert shape (Determines the size and type of rhomboid-shaped insert it accepts)
N - Tolerance class
R - Cutting direction (Right-hand cutting)
This tool utilizes a robust clamp mechanism to hold a single-sided, positive rake insert securely. This design allows for quick and easy insert changes with minimal downtime, making it highly efficient for a wide range of general-purpose external turning applications.
Key Features:
Clamp Mechanism: Offers a strong, reliable, and user-friendly method for securing the cutting insert, facilitating fast indexing and replacement.
Positive Rake Geometry: Typically designed for positive rake inserts, which reduces cutting forces, generates less heat, and allows for sharper cutting edges, resulting in better surface finish on the workpiece.
Standardized Design: As an ISO-standardized tool, it ensures compatibility and interchangeability across different machine shops and brands.
Right-Hand Cutting: The "R" in the code indicates it is intended for right-hand cutting (tool travels from right to left).
Applications:
It is a versatile tool suitable for finishing and medium-duty roughing of materials like steel, stainless steel, cast iron, and non-ferrous metals.
