Detailed information on SDK-50B dual color metal engraving machine:

Bicolor metal engraving machineIt is an electronic engraving instrument produced according to user requirements, which can be in black and white colors. It can engrave, number, draw lines and various patterns on fixtures, knives, gauges, molds, mechanical parts and instruments,Bicolor metal engraving machineWidely used in industrial and mining enterprises, scientific research, metrology, material management and other departments. This machine has a beautiful appearance, small size, light weight, and is easy to carry and use. During electroplating, the small amount of heat generated ensures that the workpiece does not deform. The depth and thickness of the engraved lines can be adjusted, and the handwriting and lines are uniform and clear.
