FIELD: process engineering.
SUBSTANCE: invention relates to woodworking industry. Machine comprises bed, loading and feeding mechanisms, basic guides directed toward working zone of the machine. Said working zone is provided with horizontal mill arranged in direction of feed to machine blank top surface. Besides, said working zone is furnished with lateral opposed vertical shaping mills to machine blank side faces. Grooving cutter is arranged ahead of horizontal mill to shape lengthwise parallel grooves at blank bottom surface. Grooving-grinding device for surface milling is arranged behind vertical mill. One basic guide is located in working zone of horizontal and vertical shaping mills. This basic guide has vertical parallel working surfaces arranged in planes of making lengthwise grooves at blank bottom surface. Another basic guide is located in working zones of grooving-grinding device and has lateral shaped surfaces located in planes of shaping sections by vertical mills on blank side faces.
EFFECT: expanded working performances.
