ABSTRACT:
A laser-guiding coordination device for a drilling machine has a C-base, two laser-line projectors oppositely and adjustably embedded inside the C-base. Each laser-line projector has a first adjuster, a second adjuster perpendicularly and rotatably mounted inside the first adjuster, and a laser generator accommodated inside the second adjuster to generate laser lines. By rotating the first and second adjusters, two laser-lines projected to a workpiece are moved in parallel or rotation to adjust and to define a precise laser mark without need for physically drawing lines on the workpiece.
