I. Alternative Names
Dual-Color Metal Engraving Machine, Electric Spark Pen, Dual-Metal Engraving Pen, Dual-Color Metal Electric Engraving Machine
II. Working Principle
Utilizing the electric discharge principle to engrave black or white markings on metal surfaces, this machine can perform engraving on ultra-high-hardness materials without compromising the workpiece’s original surface flatness. It is suitable for black-and-white engraving and serial number marking on various tooling, fixtures, cutting tools, measuring instruments, molds, and metal components.
III. Main Applications
Engraving black-and-white graphics, letters, and symbols on various metal surfaces
Marking lines during fixture machining; line width and engraving depth are freely adjustable, resulting in clear characters and uniform, neat lines
The equipment is simple to operate, stable, and reliable, ensuring no deformation or damage to the workpiece; widely used in instrument manufacturing, precision bearings, precision machined parts, the electronics industry, metrology and testing, materials management, and other industries
IV. Typical Application Scenarios
Engraving and numbering on measuring tools, fixtures, cutting tools, molds, and various hardware tools
V. Key Product Features
Suitable Materials: All conductive metals, including copper, steel, iron, aluminum, chrome-plated parts, zinc-plated parts, etc.
Engraved markings are heat-resistant and corrosion-resistant, providing permanent identification.
Not limited by metal hardness; even high-hardness materials such as cemented carbide can be engraved normally.
The engraving depth is extremely shallow, so the metal surface remains flat after processing.
VI. Instructions for Use
The surface of the workpiece must be wiped clean and kept dry to ensure good electrical contact
After selecting the engraving color, securely clamp the ground wire alligator clip to the workpiece and turn on the device
During operation, keep the engraving pen perpendicular to the workpiece and move the tip slowly and at a steady speed; maintain an appropriate gap between the tip and the workpiece, and adjust the device’s output power until the text, graphics, and lines appear clearly
When performing electro-engraving on aluminum surfaces, the copper wire tip must be replaced (the tip is to be provided by the customer).
VII. Technical Specifications
Input Voltage: 220V 50Hz
Power: 50W
Dimensions: 250 × 180 × 50 mm
Net Weight: 2.7 kg
VIII. Precautions
During engraving, ensure the engraving pen is held perpendicular to the workpiece surface, maintaining a gap between the pen tip and the workpiece to ensure normal vibration and discharge of the pen tip.
Do not allow the pen tip to remain stationary at a single point for extended periods, as this can easily cause the pen tip to burn out or become damaged.
When the equipment is not in use, do not allow the metal part of the pen tip to come into contact with any metal objects connected to the alligator clip to prevent damage to the equipment.
