摘要：Under conventionally controlled drilling machine the depth controlled cannot be made possible. Due toover drilling the job gets failed. While drilling we cannot measure the drilling depth during drilling process. Hence thesemiautomatic drilling machine will automatically control the depth of the job and it of safer mode. In some cases dueto over drilling the work bench will gets destroyed or the tool will be damaged. Hence for these conditions our projectwork had been taken up to get through the new technologies. This made the drilling machine easier. Thissemiautomatic drilling machine is very well used in mechanical workshops and it made the work easier. It consumesless time and the finishing process will be quite easier, while compared to the conventional drilling machine.
