<p>The present invention relates to a device for machining an insertion groove for a buffering member for a doorframe, which comprises: a driving motor; a rotary blade which is combined with the driving motor, and forms a groove on a doorframe through interlocking during rotation; a vertical supporting plate which is combined with the driving motor; an interval regulating plate which is fixated to the vertical supporting plate in the horizontal direction, has a blade penetration hole, for the penetration of the rotary blade, and an accommodation space unit, for accommodating machining foreign materials generated from machining, formed at the central part thereof, and an air passage for supplying air, formed at one side or both sides of the accommodation space unit; and an air supplying unit which injects air to the air passage of the interval regulating plate. Therefore, the device can prevent foreign materials such as sawdust from being fixated and attached to the rotary blade during machining work of the rotary blade by supplying air to the accommodation space unit of the interval regulating plate where the rotary blade is placed and by mounting a transparent cover on the circumference thereof, can prevent the machining foreign materials from spreading to the outside, and can increase work efficiency and the quality of products by performing accurate work.</p> |
