  • Personalising machine with an open structure
    Don’t let your personalising machine decide what you can or can't engrave. Even though it is a desktop engraving machine, the M40 has a 210x305mm engraving area that benefits from an open structure to allow larger items to be engraved when needed.

    The M40 Gift version includes an automatic lubricant tank and a rotary device to engrave and personalise glasses and bottles. The rotary device can be tilted for conical items. Ideal for gift engraving.
