The structure and principle of the drilling and milling machine

The drilling and milling machine is a small and medium-sized general-purpose metal cutting machine that can be used for both horizontal and vertical milling. It is suitable for drilling, expanding, reaming, boring and hole machining; for example, wafer milling machines, viewpoint milling cutters, forming milling cutters and end milling cutters, which can be used to mill planes, bevels, vertical surfaces and grooves. It can be used as a multi-directional milling operation after the attachment of the vertical milling head. After the attachment indexing head is attached, it can be used for milling operations such as straight teeth, bevel gears and helical teeth with a number m=3 mm or less. Because this machine tool is widely used, it is suitable for the general repair and tool workshop; it is suitable for single or small batch production workshop.

The structure of the drilling and milling machine is composed of nine main parts, such as the bed body, the base, the triangle body, the work table and the sliding seat, the sliding arm rotating seat, the milling head, the cooling and smoothing, and the electrical system. The bed is placed on the base, and the bed is placed in the lower abdomen. Main motor. It is transmitted to the bed gear box through a pair of V-belt pulleys, and is driven to the main shaft through six pairs of gears. The front end of the main shaft is a Mohs No. 4 taper hole. The tool end milling cutter shank can also be equipped with a arbor. The other end of the long shank is supported in the bearing hole of the pylon, and the shank bracket is mounted on the dovetail rail of the sliding arm.
