Introducción
In the field of advanced materials processing, precision and surface quality are critical. The Máquina cortadora de hilo diamantado sin fin—also known as a sierra de hilo diamantado de bucle—is an innovative solution engineered specifically for slicing hard and brittle materials with exceptional accuracy, speed, and surface finish. It represents a significant upgrade over traditional internal diameter saws (ID saws), band saws, and slurry-based multi-wire systems.
This article outlines the structure, working principle, advantages, and typical applications of this high-precision cutting technology.
1. What Is an Endless Diamond Wire?
En hilo diamantado sin fin is a closed-loop cutting tool—essentially a metal wire electroplated with diamond abrasives throughout its length and joined end-to-end to form a continuous ring. Unlike traditional wire saws that use a long reciprocating or unwinding wire (typically >1,000 meters), endless wires are much shorter (commonly 5–10 meters) and rotate continuously in a single direction at high speed—up to 80 meters per second.
2. Working Principle of Endless Diamond Wire Cutting
The endless wire rotates at a constant speed, creating a linear motion at the cutting point. A feed system gradually pushes the workpiece into the moving wire. Since the wire runs unidirectionally without reversing, the motion remains extremely stable, leading to:
- High surface finish
- Minimal vibration
- Narrow kerf width (often 0.35–0.5 mm)
- Reduced risk of material chipping or cracking
Different types of electroplated coatings—such as full-coated, helical, or segmented—are used depending on the material properties and cutting requirements.
