3 Type

The basic type of the machine has the following two ways.

a) a type Framed by the machine bed, and on both sides of the (fixed side and movable side) drilling heads, feed rollers, the workpiece support rollers and other components. Drilling Each drilling head either direction perpendicular to the feeding direction of the workpiece, the workpiece can be moved along the feed direction. Each drilling head slide The stage is controlled by two CNC axes. Axis direction and movement of a machine type shown in Figure 1.
