Gravotech - M40 rotary engraving machine

M40, personalising machine for gift engraving

The M40 is a versatile personalising machine. Its large engraving area makes it a perfect desktop engraving machine for medium-sized items and plate engraving.
  • 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.
  • Engrave glass with the M40
    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.
  • Adapted for beginners
    Control and adjust your personalised engraving with our dedicated Gravostyle™ or ABC engraving. The M40 comes with an auto-centering jig and a laser beam (Point & Shoot) to help you place the item to engrave, while the engraving software automatically picks up its position.
