English Translation of Title:
R-100 Focusing Tube for Water Jet Cutting Machine Parts – 00210533 mm x 200508 mm, Model No. 10139426-R-100-Focusing-Tubes-00210533-mm-x-200508-mm.1042.3-1

*(Note: The numerical values "00210533 mm" and "200508 mm" in the part number are product-specific reference codes, not actual physical dimensions. Typical focusing tubes are precision small components, roughly 50–200 mm long and 5–30 mm in diameter.)*

Introduction, Application, Features, and Maintenance:

This component is a focusing tube – also called a mixing tube or nozzle – for abrasive water jet cutting systems. It is installed in the cutting head, where it receives the high‑pressure water and abrasive mixture from the mixing chamber and directs it through a precisely sized bore to form a coherent, high‑velocity cutting jet.

Application:
Used in the cutting head assembly of abrasive water jet cutting machines. The focusing tube is the final component that shapes and concentrates the abrasive slurry into a narrow, powerful jet for cutting materials such as steel, aluminum, stone, glass, and composites.

Features:

• Withstands extreme pressures (up to 6,000 bar / 87,000 psi) and high‑velocity abrasive flow.

• Made from ultra‑hard, wear‑resistant materials – typically tungsten carbide or ceramic.

• Precision‑ground internal bore ensures jet coherence for accurate, narrow‑kerf cutting.

• Directly influences cutting speed, kerf width, surface finish, and nozzle life.

• Available in multiple bore diameters and lengths to match different materials and thicknesses.

• Designed as a consumable wear part for quick and easy replacement.

Maintenance:

• Inspect the focusing tube frequently for bore enlargement, erosion, cracks, or chips.

• Monitor cutting performance – slower cutting, wider kerf, or rougher edges indicate bore wear.

• Replace the tube immediately when the bore exceeds tolerance or when cut quality falls below standard.

• Handle carefully to avoid chipping the brittle tungsten carbide or ceramic material.

• Use proper tools and procedures during installation and removal.

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

• Adhere to the manufacturer’s recommended replacement intervals based on operating hours.
