The economical Disc Type Special Machine is an automatic machine tool with high precision and high efficiency. Equipped with multi-station turret or electric turret, CNC small lathe has a wide range of processing performance, can be processed straight barrel, inclined barrel, arc and a variety of thread, groove, worm and other complex workpieces. Widely used in electrical appliances, instrumentation industry, automobile, motorcycle parts, fasteners, bearings, photographic equipment, film machinery, hardware tools, watches, eyes, stationery, motors, valves, gas pipe accessories and other high-precision processing and manufacturing. Complex parts, it is the ideal high-efficiency equipment in the hardware machining industry. The economical Disc Type Special Machine was developed on the basis of the ordinary lathe, but its degree of automation has been greatly improved. The economical Disc Type Special Machine automatic control system is mainly composed of single chip microcomputer. Through the control program, the longitudinal and transverse feed device and tool changing device of the machine tool are controlled to automatically complete the machining of the parts.

Economy Disc Type Special machines are also handled differently. After the economical Disc Type Special Machine program is completed, the tool does not return to zero, which is usually caused by a control system failure. When feeding or machining, the tool is required to run at a low speed. At this time, the stepper motor runs at a low speed and is powered by a low-voltage power supply. When the program returns to zero, the stepper motor is required to operate at high speed and use high voltage drive power to increase the output torque and ensure a normal return to zero. When the switching transistor is damaged and the high-speed return to zero, the high-voltage power supply cannot be opened, and the output torque of the stepper motor is insufficient, resulting in a regression to zero out of step, resulting in the tool unable to return to the origin, for which the fault can be eliminated by replacing the switching transistor.
