Rough Indexable Boring Head:

The CBK-I Rough Indexable Boring Head-Twin Type I is a high-performance tool used for rough boring operations in CNC machining.

Rough boring heads are designed for removing large amounts of material quickly and efficiently. These tools use Indexable inserts to give multiple cutting edges that allow for high-feed rates and heavy cuts during rough machining operations. Indexable means that the cutting inserts can be easily replaced or rotated once they are worn out, offering significant savings in operational costs and tool life.
Twin Type : It indicates that the boring head has two cutting edges or inserts, allowing for balanced cutting forces, better stability, and improved surface finish. This design helps reduce vibrations during heavy machining and increases the rigidity of the boring operation.
Range 20 to 26 mm: Indicates the diameter range of the holes that the CBK-I Rough Indexable Boring Head-Twin Type is designed to machine. This means the boring head is suited for machining holes with diameters in this range. The diameter is adjustable through insert positioning, equally shifting the 2 opposite slides each carrying an insert, allowing for flexibility in hole size.

CNC Machining:
- Used in CNC machines for rough boring operations, such as creating larger holes in metal workpieces. Ideal for industries such as automotive, aerospace, and mold-making.
Heavy Stock Removal:
- The tool is designed to handle heavy material removal, making it suitable for initial boring steps before finer finishing operations are carried out.
Deep Hole Machining:
- Since it has twin inserts, it can maintain stability even during deep hole machining, which is essential in applications where holes need to be drilled or bored deep into the workpiece.
Versatility Across Materials:
- Suitable for machining a wide variety of materials, including steel, cast iron, and aluminum, among others. It's also effective in operations that require high feeds and speeds.
Custom Boring and Precision Work:
- This type of boring head is great for jobs that require precision in the initial stages of machining, such as automotive engine block machining, gearbox housings, and other complex metal parts.

High Material Removal Rates:
- The rough boring head is optimized for high material removal rates, making it suitable for operations where time and cost efficiency are important.
Increased Tool Life:
- The use of indexable inserts allows for the replacement or rotation of the cutting edges, extending the life of the tool and reducing tool change time. This helps lower the overall cost per part.
Reduced Vibration and Tool Deflection:
- The twin insert design ensures that the cutting forces are balanced, which helps reduce tool vibration and deflection. This leads to higher accuracy and better surface finishes during rough boring operations.
Flexibility in Hole Sizes:
- With an adjustable diameter range of 20 to 26 mm, this tool provides flexibility to work on different hole sizes without needing multiple tools.
Improved Surface Finish:
- Despite being a rough boring tool, the balanced cutting action ensures that the workpiece receives a reasonably good surface finish, reducing the need for additional finishing operations.
