Boring Bar Connecting Rod
Product Description:
A Boring Bar Connecting Rod is a critical, precision-machined tool accessory used in machining to extend the reach and connection between a machine spindle (on a lathe, milling machine, or boring machine) and a boring tool holder or cutting head. It enables the machining of deep, internal diameters (bores) with high accuracy and stability that would be impossible with a standard, short boring bar. Essential for achieving precise bore dimensions, surface finish, and concentricity in deep-hole applications.
Key Features
| Feature | Description |
|---|---|
| Precision Extension | Extends the working length of the boring setup, allowing tools to reach deep into pre-drilled holes or inside cavities for internal machining operations. |
| Enhanced Rigidity & Stability | Manufactured from high-strength materials (alloy steel, carbide) with a robust diameter-to-length ratio to minimize deflection and vibration during cutting, which is crucial for achieving tight tolerances and smooth surface finishes. |
| Versatile Connection Interface | Features precision-machined ends with standardized tapers (e.g., Morse Taper), threads (e.g., internal/external), or flange mounts to ensure a secure, concentric connection between the machine spindle and the boring head or cutting tool. |
| Critical for Deep-Hole Boring | The fundamental enabling component for deep hole boring, internal grooving, and precision internal turning operations on engine blocks, cylinders, hydraulic housings, and other components requiring deep, accurate bores. |
Typical Technical Specifications:
-
Type: Tool Extension / Connecting Rod for Boring
-
Material: High-Strength Alloy Steel, Carbide (for maximum rigidity)
-
Connection Types: Morse Taper shank (MT2, MT3, etc.)
-
Key Dimensions: Diameter and Useful Length (e.g., Ø25mm x 150mm long)
-
Primary Function: Transmit torque and provide a rigid, accurate extension for boring tools.
Applications:
-
Deep Hole Boring & Internal Machining: On CNC lathes, milling machines, and dedicated boring mills.
-
Engine & Cylinder Machining: For automotive, aerospace, and industrial motor rebuilds.
-
Mold & Die Making: Creating precise cavities and internal features.
-
General Precision Machining: Any application requiring accurate internal diameter work beyond the reach of standard tooling.
Advantages:
It solves the fundamental challenge of reaching and accurately machining deep internal surfaces. Without a proper connecting rod, the flexibility and vibration of an overly long cutting tool would make precision boring impossible.
