Working Principle of Diamond Wire Saw

1. Definition of Diamond Wire Saw

A diamond wire saw, also known as a diamond bead saw, is a diamond tool made by sintering, electroplating, brazing, and other methods to create a string of beads, which are then connected together through processes such as glue injection and injection molding.

 

 

2. Types and Applications of Wire Saws

Wire saws are categorized by the type of cutting object:

• Granite wire saws,
• Marble wire saws,
• Sandstone wire saws,
• Concrete wire saws,
• Factory special-shaped wire saws,
• Slab cutting wire saws, etc.

They are primarily used in stone mining, factory stone processing, and concrete bridge cutting.

 

 

3. The Difference Between Wire Saws and Diamond Wire Cutting

• Diamond wire cutting: Primarily used in the solar energy, sapphire, and optical glass industries, diamond wire cutting utilizes electroplating to coat diamond powder onto a steel wire a few tenths of a millimeter thick. Cutting is achieved using a long, retractable drum-like wire. High precision is required.

 

• Diamond wire saw: Primarily used in the stone and concrete cutting industries, it is a flexible cutting tool that requires less precision.

 

4. Working Principle of a Diamond Wire Saw

Powered by an external device, it grinds the object being cut at high speed. Powder is formed during the cutting process, and grinding generates heat, so water cooling is required.

Principle of Envelope Line and Envelope Angle:

The envelope line primarily refers to the line segment in contact with the object being cut, such as the existing line segment between points A and B in the figure above.

 

The envelope angle refers to the angle formed by the upper and lower line segments, such as the angle between points AB.

According to the physical principle of work, the greater the resistance, the less useful work is done. The longer the envelope line, the greater the resistance it encounters. The greater the resistance, the slower the cutting speed. Therefore, the shorter the envelope line, the better.

 

While the wire saw is performing circular motion, it is also rotating, much like the Earth rotating while orbiting the Sun. This is because the beads need to be evenly distributed to achieve maximum utilization. A smaller angle makes it less likely that the beads will rotate, shortening the wire saw's cutting life.

 

Therefore, the envelope line and envelope angle are factors that affect the cutting speed and service life of the wire saw. During use, we try to shorten the envelope line and increase the envelope angle.
