Gun Dirlling Machines To Drill Holes of Plastic Injection Molds

1. Manually line and draw a circle slightly larger than the hole. When the electric drill is processed, it can be a shallow hole in the center of the hole, and the electric drill is slightly perpendicular to the inclined plane to drill, forming a transition hole, and then the electric drill is placed back in the correct position and begins drilling, while paying attention to whether the processing hole deviates from the reserved line hole. Electric hand drill, point processing is appropriate.

 

2. Sample punch, use the center drill to make the center hole, or use the milling cutter to drill and mill the small platform, and then the bit processing, the feed must not be too large.

 

3. The workpiece can be placed horizontally, drill a shallow nest, slightly tilt some gradually expand the hole, after several adjustments, the workpiece square, processing.

 

4. Production of inclined jig processing

 

5. The use of circular edge multi-function bit, select a short bit (to ensure rigidity), manual grinding into circular edge bit, grinding the transverse edge, cutting is still a single force but now is a circular surface, the force is small, improve the situation of single force, so as to ensure the processing of oblique face.
