After refitting ordinary machine tools into economical numerical control lathes, the work efficiency can be increased by 1-4 times, the scrap rate can be reduced, the product quality can be improved, and the labor intensity of workers can be reduced. Renovation costs are usually recovered in about a year.
Generally, single board microcomputer is used as control device for high-speed Gong machining, and stepping motor is used as actuator to transform ordinary machine tool into economical numerical control lathe. The modified machine tool not only retains the versatility of the original machine tool, but also adds many features that traditional machine tools do not have, such as automatic tool setting, gap compensation, automatic feed speed adjustment, automatic return to the original point and so on. This kind of machine tool is especially suitable for the frequent and rotational processing of rod, shaft, disc parts and parts with taper and spherical surface.
Economic CNC lathes can be divided into three types according to the driving system
- Open loop system driven by stepping motor. This kind of system is widely used. Economical CNC lathe can finish the machining of cylinder, plane, cone, curved surface and thread.
- Point position numerical control system driven by asynchronous motor or DC motor, grating measurement feedback.
- A semi closed loop system driven by DC servo motor for high speed Gong machining. This kind of system is mainly used for new machine tools because of its high price.
- High speed computer gongs use precision level instrument and other detection tools, mainly by adjusting the pad iron way to fine adjust the level of the main bed of the machine tool, so that the geometric accuracy of the machine tool can reach the allowable tolerance range;
- For the automatic tool change device, adjust the position of the tool magazine, manipulator, travel parameters, etc., and then check the action with the command, which is required to be accurate;
- For the machine tool with APC automatic exchange table, after adjusting the relative position, carry out automatic load exchange;
- After the adjustment of the machine tool, carefully check whether the parameter setting values in the numerical control system and the programmable controller conform to the data specified in the random index, and then test the main operation functions, safety measures, execution of common instructions, etc.
- High speed computer gong to check the normal operation of auxiliary functions and accessories of the machine tool. It is usually composed of CNC system, main drive system, feed servo system, cooling smooth system, etc
It is used to clamp the tool and rotate the tool. The spindle speed scale and output torque have a direct impact on the machining. 2. The feed servo system is composed of feed motor and feed actuator. According to the feed rate set by the program, the relative motion between the tool and the workpiece is completed, including linear feed motion and rotary motion. 3. Control system CNC milling machine motion control in the middle of the implementation of NC machining program control machine tools for processing. Computer gong processing, Dongguan computer gong processing, high speed computer gong processing, mechanical parts processing, computer gong processing, auxiliary equipment such as hydraulic, pneumatic, smooth, cooling system, chip removal and protection equipment. 5. The base parts of high-speed computer gong machine tools usually refer to the base, column, beam, etc., which are the foundation and structure of the whole machine tool.
