The DMwriter MX Marking Head was designed as an easy-to-use, economical, spindle-actuated permanent marking device for a wide variety of materials, from hardened tool steel to delicate plastics. Since the device does not rely on electrical or compressed air input or any similar interfacing, it is easily integrated into vertical or horizontal machining centers, milling machines and equivalent CNC machines with a rotating spindle.

The DMwriter MX is a very cost-effective, smart alternative to vibrating stylus heads, pin marking machines and other alternative marking methods such as chemical etching, die or roll stamping, laser markers and messy ink printers.

Mechanical CNC Marking Tool Sample

Mark parts directly in CNC milling equipment
No electric or pneumatic input required
Use standard CNC engraving software
Mark alphanumeric text, symbols and logos
Use existing machine tool fixturing
"Marking window" size is limited only by the machining envelope of your machine tool

DMwriter MX CNC Mechanical Marking Tool

The DMwriter MX has a number of important advantages over conventional marking methods. The DMwriter MX is a spindle-actuated mechanical dot peen marker, which cold-forms a series of discrete or connected dots with precise, low-stress marking force. The device accurately and indelibly marks alpha-numeric text, symbols, dates and serial numbers, batch codes, logos and graphics. Various fonts and character sizes can be marked in straight-line, angled, arced, circular, mirrored or reflected text. The carbide stylus can easily mark in a wide variety of materials. It clearly marks cast iron or steel as hard as 55 HRc or dense material like heavy metal, but just as easily marks softer materials like aerospace alloys, aluminum, other nonferrous metals, and delicate plastics. If you require a pneumatic CNC marking solution, please contact us to discuss your application.

The installation process is similar to integrating a tapping head or angle head into a milling machine. The DMwriter MX can be manually mounted in the machine spindle, or it may be placed in the machine's ATC (automatic tool changer) and automatically loaded into the spindle.
