Engraving stylus, also called diamond stylus, engraving needle, engraving knife or carving needle, is installed in engraving machines to engrave text, images or pattern on the copper cylinder.
Engraving Stylus, Sliding Shoe and Burr Cutter are precision diamond tools for rotogravure plate-making industry. All of these diamond tools are mounted on the engraving head which is a core component of the engraving machine.
A diamond stylus for the rotogravure industry is a precision tool used in the rotogravure printing process. It is a small, pointed tip made of diamond, which is renowned for its hardness and durability.
In rotogravure printing, the diamond stylus is used to engrave fine lines and details onto a cylinder or plate. The stylus is attached to a mechanical device that moves it along the surface of the cylinder or plate in a controlled manner. As the stylus moves, it removes a thin layer of material, creating the desired image or pattern.
The HELL diamond stylus for the rotogravure industry is crucial for achieving high-quality prints with fine details, sharp edges, and accurate reproduction of images and text. The hardness and sharpness of the diamond allow it to create precise and consistent engraving, and ensure the reproduction of intricate designs and high-resolution images.
The use of HELL diamond styli in the rotogravure industry helps achieve high print quality, efficiency, and productivity in applications such as packaging printing, labels, magazines, and commercial printing.
HELL diamond styli are available in different shapes, sizes, and tip geometries to suit specific rotogravure applications and printing requirements.
We can produce all kinds of Engraving stylus for HELL gravure systems, OHIO gravure systems and MDC gravure systems. 20+ years' experience, strongly production capacity and first-class material make our engraving stylus can meet the engraving requirements of all kinds of products, especially for the high-grade cylinder engraving.

Attentions:
When you install the electronic engraving stylus, please don't touch the diamond cutting edge directly with your hands or other objects. If you need to wipe it, please use isopropyl alcohol , acetone & a lint free cloth or an elder pith. If you need more aggressive cleaning in order to remove a particular contaminant, please contact us.
Broken Engraving Stylus
The engraving stylus may break for various reasons.
Possible causes of broken stylus tip
1. Broken tips result from incorrect setting at the engraving amplifier. The stylus penetrates more deeply than actually intended for the cut of the diamond; the rear "free" facets of the stylus hit the copper with each cut which result in the stylus overloaded and broken prematurely!
2. Impurities in the copper and excessive Vickers hardness also cause breakage. Its inclined position minimizes the risk of breakage. The cut of the stylus diamond is designed for a specific cutting behavior. The respective forces occurring during the cutting and burr removal stroke are therefore coped for with no problem. Once the force directions acting on the diamond change, the tip will break. An insufficient Vickers hardness results in poor chip removal and therefore in a poor (blurred) engraving image.
3. Other causes of tip breakage may be due to incorrect handling, such as when setting down the engraving system hard with the sliding spindle set too short, etc.
Coarse breakage
The engraving stylus may break for various reasons.
1. The cutting diamond hits hard particles in the copper or the cylinder grinding residue (abrasive grit) or porous points (cavities) in the copper, such as coarse copper structure.
2. Attempts to clean the engraving stylus with a brush or fingers. Diamonds are generally known for their hardness and strength, but even slight contact can result in damage and destruction and render the stylus unusable.
3. Attempts to clean with compressed air are just as dangerous for the stylus. If a particle of abrasive grit or dust strikes the cutting edge of the stylus at great speed, it will destroy the cutting edge. Furthermore, it is also possible that a blast of compressed air could blow copper burr into the bearings of the engraving system which would then have a detrimental effect on the stylus damping.
