Existing lock drilling machines are all bench drilling machine tools. A drill bit is installed on a drilling machine, and a drilling machine can only punch holes on one surface of the lock body, and can only punch one hole. It needs multiple punching machines to complete all the holes on the square lock body. The punching process of the existing lock punching machine is as follows: the operator first installs the lock body on a punching machine to punch holes, punch After the hole is completed, remove the lock body, and then place it on another punching machine for drilling. After the hole is completed, remove the lock body, and proceed in sequence until the hole is completed. The reason is that the size and depth of each hole are different, so The corresponding drill bits are different, so multiple punching machines are required to punch holes in multiple steps. The punching process is cumbersome and the production efficiency is low. There are also many punching equipment and punching machine operators required, resulting in high production costs.
