Vow, this is a new generation professional Desktop CNC milling machine. DMC-III is manufactured by ACT machines in Los Angeles, California USA. This is compact light weight high precision and highly reliable Machine.
The attached picture was taking from a special camera which demonstrates the precision 3D contour capability. The DMC-III produced the aluminum mold used to manufacture this 2 mm x 2 mm plastic face. This is so tiny but you can see he is smiling. ( a grain of rice at left for reference). The mold is shinning smooth resulting from the CNC milling without any polish.
