Technical Field

The utility model belongs to the technical field of planer drilling machine, concretely relates to many drill bits planer drilling machine.

Background

The drilling machine is a machine tool which mainly uses a drill to machine a hole on a workpiece. Typically the drill bit is rotated into a primary motion and the drill bit is moved axially into a feed motion. The drilling machine has simple structure and relatively low processing precision, and can drill through holes and blind holes. The special cutter is replaced, and the machining such as reaming, spot facing, reaming or tapping can be carried out. In the machining process, the workpiece is fixed, the cutter moves, the center of the cutter is aligned with the center of the hole, and the cutter rotates. The drilling machine is characterized in that a workpiece is fixed and a cutter does rotary motion. The drilling machines can be divided into automatic drilling machines and manual drilling machines, and although most of the current industrial production are automatic drilling machines, the manual drilling machines still play an irreplaceable role in terms of flexibility and economy for some small-lot and test drilling machines.
