English Translation of Title:
Focusing Tube for Water Jet Cutting Machine Parts – R 100, 00431092 mm x 313794 mm, Model No. 10126928-Focusing-Tubes-R-100-00431092-mm-x-313794-mm.1052.3-1

Note: The dimensions in the part number appear unusually large. This may be a specific coding reference rather than literal dimensions. In practice, focusing tubes are typically small (e.g., 100–200 mm length, 10–30 mm diameter). The description below focuses on the functional characteristics of a typical focusing tube.

Introduction, Application, Features, and Maintenance:

This component is a focusing tube (also known as a mixing tube or nozzle) designed for abrasive water jet cutting systems. It is a precision-machined cylindrical tube that focuses the high-pressure abrasive water jet into a coherent, high-velocity stream for cutting materials.

Application:
Installed at the cutting head assembly of abrasive water jet cutting machines. It receives the high-pressure water and abrasive mixture from the mixing chamber and directs it through a narrow bore to form a concentrated cutting stream that impinges on the workpiece.

Features:

• Rated for extreme pressures and high-velocity abrasive flow common in water jet cutting.

• Manufactured from ultra-hard, wear-resistant materials such as tungsten carbide or ceramic to withstand abrasive erosion.

• Precision internal bore ensures a consistent, coherent cutting stream for high accuracy.

• Designed for optimal focusing of the abrasive jet to achieve clean, narrow kerf cuts.

• Available in various inner diameters and lengths to suit different cutting applications.

• Critical component that directly affects cutting quality and efficiency.

Maintenance:

• Regularly inspect the focusing tube for signs of wear, erosion, or bore enlargement.

• Monitor cutting performance; decreased cutting speed or wider kerf may indicate bore wear.

• Replace the focusing tube immediately when bore diameter exceeds acceptable tolerance or cutting quality degrades.

• Use only recommended tools and procedures during replacement to avoid damage.

• Handle with care to prevent chipping or cracking of the hard ceramic/metal material.

• Keep the cutting head and mixing chamber clean to extend focusing tube life.

• Follow manufacturer's recommended replacement intervals based on operating hours.
