Suitable for machining various small and medium-sized parts, especially non-ferrous metals, plastics, and nylon. They feature simple structure and flexible operation, and are widely used in single-piece or batch manufacturing; instrumentation; construction decoration; and repair shops. A drilling and milling machine is a small to medium-sized general-purpose metal cutting machine tool, capable of both horizontal and vertical milling. It is suitable for drilling, reaming, boring, and hole machining; with disc milling machines, angle milling cutters, forming milling cutters, and face milling cutters, it can mill planes, inclined planes, vertical surfaces, and grooves. With the attachment of a vertical milling head, it can perform multi-directional milling operations. With the attachment of a dividing head, it can perform milling operations on spur gears, bevel gears, and helical gears with a module m=3 mm or less. Due to its wide application, this machine tool is suitable for general repair and tool workshops; and for single-piece or small-batch production workshops.
The machine tool structure consists of nine main components: bed, base, triangular block, worktable and slide, slewing arm, milling head, cooling and lubrication system, and electrical system. The bed is mounted on the base, with the main motor housed in its lower section. Power is transmitted to the I-axis via a pair of triangular pulleys, then to the bed gearbox, and finally to the spindle via six pairs of gears. The spindle's front end has a Morse taper bore (No. 4). It can be used to mount end mill holders or tool holders. The other end of the longer tool holder is supported in a bearing hole in the hanger, and the tool holder support is mounted on the dovetail guide rail of the slide arm.
