The engraving styli for HELL/MDC/OHIO machines are not only produced on sophisticated polishing benches, but during polishing, monitored by interference microscopy in order to secure the surface finish. The angles of each individual stylus are measured with an in-house developed 3D laser measuring device. Strict quality control ensures that the products are manufactured to meet or exceed the required specifications.

1. Working principle for engraving styli
Engraving styli are used for incising the precise apertures on copperplate, the operating frequency is 8000 Hz (ie, up to 8000 apertures per second), various angles of the diamonds are available for diverse using demand.
Our professional technicians and quality manage system obtains the minimum tolerance and high precision.

2. Using caution and cleaning for engraving styli
As we all know, diamond possesses the best hardness but poor roughness, so please do not touch the tip with your finger or textile fabrics, for even a slight touch would damage the tip and lead to an inefficient stylus. The pyramid would explicate all.
A stone made pyramid would keep a certain structure since one above another, the above press won't destroy this structure, however, crosswise, a comparatively little force will ruin the whole structure.
When engrave with an engraving stylus, the strength is mainly on its tip (just like the tip of a pyramid),so it is affordable. However, you touch the tip with your finger, it is more or less like uncontrollable force to the unstable pyramid, then lead to a partial tip damage.Cleaning with compress container would lead to same aftermath, if a hard grit or even dust drops on stylus's tip with a high speed, the stylus will get damaged.Furthermore, compress air would probably blow the copper scrap into the gravure system, which also influences a stylus' life.

3. How to clean the diamond of the stylus
Usually, we are not allowed to touch the diamond of the stylus, instead, we use HELL set-up system to set up or remove the stylus, in this way, you may avoid to touch the diamond.You're allowed to clean the diamond after you make sure it necessary with microscope examination. By the way, the vacuum drawer of the HELL machine is available for copper pile.
