Pneumatic roller engraving machine

The pneumatic roller engraving machine is operated by a hard mandrel (template), so it cannot engrave serial numbers, and to engrave variable text, a mandrel specific to that text must be prepared.

It should be kept in mind that due to the differences in the shapes and dimensions of the parts, a suitable fixture must be made for each part.

Pneumatic roller engraving machine

Engraving in this method is done by rolling the piece with the pressure of a hard mandrel on the piece. In this way, the piece is placed on the rolling rollers and the movement of the mandrel with pressure from the piece causes it to rotate. For example, the mandrel moves from left to right and rotates the piece clockwise. The mandrel is made of plated steel and is very resistant to pressure.

It should be noted that the parts must be cylindrical and made of metals such as brass, copper, aluminum, steel, iron, cast iron, bronze and compressed plastic (this method is not recommended for engraving on hardened parts). The engraving depth can be adjusted from 0.1 to 1mm depending on the hardness of the part.

The required force can be selected as a manual lever, pneumatic engraving, hydraulic engraving, or electric motor, depending on the size of the mandrel and the type of part.

Application of pneumatic roller engraving machine

As mentioned, this device is used for engraving on all types of cylindrical parts, and manufacturers of high-pressure fittings, flanges, and generally manufacturers of all industrial parts whose parts are cylindrical have the possibility of using this device to engrave their technical specifications and logos.

The roller engraving machine has the ability to engrave fixed parameters, and to change the text, the engraving cylinder must be replaced. And for this purpose, we need to make different cylinders. So, in addition to the previous points, this point also makes the pneumatic roller engraving machine suitable for high-volume production.

Roller engraving machine feature

We would like to draw your attention again to the fact that this machine cannot engrave phrases that change frequently. For example, a serial number is a phrase that changes frequently, so this machine is not a good choice for engraving serial numbers, and computer-controlled engraving machines (CNC) in impact engraving, scribe engraving, or laser engraving models should be used. Because in these machines, the engraving pen moves based on computer commands and is capable of engraving any phrase.

Engraving in pneumatic or air-powered machines is done with compressed air and involves less manpower compared to manual machines. As a result, they are suitable for large-volume production. We recommend that dear craftsmen who are looking to purchase a roller engraving machine read the following and become more familiar with the advantages and disadvantages of this machine. You can also seek advice from the site’s online support.
