Carbide Insert CNMG1204 TC (pack of 10 1box)
The CNMG120404 is a commonly used carbide insert for turning operations, particularly suitable for machining cast iron. The "120404" refers to specific dimensions: a 12.7mm inscribed circle diameter, a 4.76mm thickness, and a 0.4mm corner radius. These inserts are typically 80° rhombic shape with a negative rake angle. They are often used for medium-to-roughing operations on various materials, including steel, stainless steel, and cast iron.
Here's a breakdown of the specification:
- cylindrical hole.
- 12: Inscribed circle diameter is 12.7mm.
- 04: Thickness is 4.76mm.
- 04: Corner radius is 0.4mm.
Specifics for Cast Iron Machining:
-
Material:CNMG120404 inserts are well-suited for machining cast iron due to their strength and ability to withstand the abrasive nature of cast iron.
-
Application:They are commonly used for medium and semi-roughing operations in cast iron. .
-
Chip Breaker:Specific chip breaker geometries (e.g., -GN, -NF) can be selected based on the desired chip control and cutting conditions for cast iron.
-
Coatings:Carbide inserts like CNMG120404 often come with various coatings (e.g., PVD, CVD) to enhance wear resistance and tool life when machining cast iron.Other Considerations:
- Rake Angle: The rake angle can be negative or positive, depending on the application and desired cutting performance.
- Toolholder: The insert is mounted in a suitable toolholder designed for CNMG inserts.
- Cutting Parameters: Optimal cutting speed, feed rate, and depth of cut should be determined based on the specific cast iron grade, machine tool capabilities, and desired surface finish.
- For more detailed specifications, consult the manufacturer's catalog or website for the specific CNMG120404 insert you are using.
