Drilling is a kind of processing method that uses drill to process holes on the product surface. What is the operation process of radial drilling machine?
1. Marking: before drilling, first understand the drawing requirements. According to the basic standard requirements of drilling, use tools to mark the middle line of the hole position. The middle line must be clear and accurate, and the finer the better. After marking, use vernier caliper or steel ruler to measure.
2. Draw check square or check circle: after drawing the line and passing the inspection, the check square or check circle with the hole center line as the symmetrical center shall be drawn as the check line during the trial drilling, so as to check and correct the drilling direction during drilling.
3. Proofing and punching: after drawing out the corresponding check square or check circle, proofing and punching shall be done carefully. First, make a small point, and measure in different directions of the cross center line for many times to see if the punching eye is really hit at the cross point of the cross center line, and then make the sample punching force positive, round and large, so as to accurately cut and center.
4. Clamping: clean the machine table, fixture surface and workpiece datum surface with a rag, and then clamp the workpiece. The clamping is smooth and reliable according to the requirements, and it is convenient for inquiry and measurement at any time. It is necessary to pay attention to the clamping method of the workpiece to prevent the workpiece from deformation due to clamping.
5. Trial drilling: trial drilling before formal drilling: the horizontal edge of the drill bit is aligned with the center sample of the hole to drill a shallow hole, and then visually check whether the orientation of the shallow hole is correct. It is also necessary to constantly correct the deviation, so that the shallow hole is coaxial with the inspection circle. If the violation is small, the workpiece can be pushed to the opposite direction of violation with force during tripping out to reach progressive calibration.
6. Drilling: machine drilling is generally manual feeding operation, when the test drilling azimuth accuracy requirements, drilling can be carried out. When feeding manually, the feed force should not cause the drill to bend, and avoid the awesome hole axis.
