Introduction Digital control driller employs AC servo motor to drive the X axis and Y axis, while its Z axis is positioned by high accuracy raster ruler. By using semi-closed closure digital control system, the machine has reliable performance. The operation of the machine can either be automatic or manual. This machine is widely used in steel frame construction. Technical parameters 1. Drilling diameter: Max. 50mm 2. Thickness of workpiece: Max. 80mm 3. Max. Dimension of workpiece: A.
