1) Electrode wire selection and threading.

The type of electrode wire is selected according to the wire walking speed of the machine tool, and the diameter of the electrode wire is selected according to the processing requirements and process conditions. If the processing requirements allow, a larger diameter electrode wire can be used. The diameter of the electrode wire is large, the tensile strength is large, and the current is large, which can improve the processing speed.

If the electrode wire is too thick, it is difficult to process the workpiece with sharp corners inside, which reduces the machining accuracy, and at the same time, the cutting gap is too wide, so that the amount of erosion of the material becomes larger, and the processing speed is also reduced.

The threading operation of the slow wire thread machine tool is relatively simple, and the wire threading operation of the fast wire thread machine tool is more complicated. After threading, the verticality of the electrode wire needs to be corrected by the spark method or using a corrector.

2) Start the machine and check.

After starting the power switch of the machine tool host, close the power switch of the machine tool control cabinet, start the computer, and enter the wire cutting control system.

Remove the emergency stop button on the machine unit; Add lubricating oil according to the lubrication requirements of the machine tool; The machine tool runs for 2 minutes without load to check whether its working condition is normal.

3) Procedures and inspections.

According to the size, accuracy, process and other requirements of the processed parts, the wire cutting processing program is compiled in the automatic programming system of the cutting machine tool and sent to the console; Or the machining program can be programmed by hand and read into the control system by a floppy drive.

The degree is simulated on the console to confirm that the program is accurate.

4) Workpiece clamping and alignment.

Wire cutting processing belongs to more precision machining, and the clamping of the workpiece has a direct impact on the positioning accuracy of the processed parts, especially in the processing of mold manufacturing, it is necessary to clamp the workpiece carefully and carefully. Many wire cutting machine tool manufacturers are equipped with their own special processing fixtures, and in the process of clamping the workpiece, the design of the workpiece or the datum plane of the processing should be parallel to the X and Y axes as much as possible; The clamping position should be conducive to the alignment of the workpiece, and should be suitable for the stroke of the machine tool; It should be ensured that the electrode wire will not be too close to or mistakenly cut the machine tool table during processing; The clamping force should be moderate and uniform to avoid deformation of the workpiece.

The alignment accuracy of the workpiece is related to the position accuracy of the wire-cut machined parts. In actual production, according to the importance of the processed parts, the methods of alignment according to the marking line, the alignment according to the reference hole or the formed hole, and the alignment according to the shape are often adopted.

5) Wire feeding and cooling.

Turn on the wire carrier for wire feeding. For fast-moving wire cutting machine tools, within a certain range, with the increase of wire speed, it is conducive to the rapid deionization of the discharge channel at the end of the pulse, and at the same time, it is conducive to the stable progress of chip removal and discharge machining. Therefore, under certain processing conditions, with the increase of wire speed, the processing speed increases.

However, after exceeding this range, the number of forward and reverse commutations of the wire storage barrel in a certain period of time increases, and the non-processing time increases, which will reduce the processing speed.

Turn on the coolant, 10) turn on the coolant;

11) Choose reasonable electrical parameters.

12) Manual or automatic tool setting;

13) Click the "Processing" button on the console to start automatic machining;

14) After the processing is completed, press the "CTRL+Q" key to exit the control system and turn off the power of the control cabinet;

15) Remove the workpiece and clean the machine;

16) Turn off the power of the machine unit.

If you are learning cutting CNC machine tools, you need to learn the content of the following books. (If you have studied the content of a book, you can skip it).

The courses you need to learn in CNC are:

Mechanical Drawing", "Mechanical Basics", "Tolerance Fit and Technical Measurement", "Metal Cutting Principles and Tools", "Machine Tool Fixture".

CNC Machining Technology", "CNC Machine Tool Programming and Operation".

The main content of each book is described below:

This is the most basic course in mechanical manufacturing, introducing the expression of various drawings, so that you can understand all kinds of drawings, which is a compulsory course. Many schools use "Mechanical Drawing" instead of "Mechanical Drawing", which is a drawing, which is more demanding than mechanical drawing.

Fundamentals of Machinery" introduces the characteristics and application occasions of various common mechanisms.

Tolerance Fit and Technical Measurement" This is a course that teaches you to understand the dimensional tolerance and geometric tolerance requirements on the drawings and their measurement methods, and it is also a compulsory course.

Principles of Metal Cutting and Tools" is a course that tells you how to sharpen, choose a tool, and choose the amount of cutting. (It may also be explained in CNC machining technology).

Machine tool fixture" This is a course that tells you the principle of part positioning and clamping, how to choose and use fixtures.

CNC machining technology is a comprehensive course of CNC major, to tell you how to process a part of the course, may cover part of the previous books, if you have a more systematic CNC machining technology book, according to the content of the book, omit some of the previous books.

As the name suggests, "CNC Machine Tool Programming and Operation" is a book on machine tool programming and operation, as long as there is rigorous thinking, this book is not difficult to learn. The content of programming is that the macro program is a little more difficult, and the operation aspect of the tool technology is the key.

In addition to the above courses, you also need to study the instructions of the CNC machine you operate.

In addition, some mathematical foundations are required, such as geometry, trigonometric functions, and plane analytic geometry. If the mathematical foundation is poor, it doesn't matter much, because you can get the coordinate values with AutoCAD drawing. Planar analytic geometry is basically the foundation for macro programs.

You don't usually need to use it.

Then learn the drawing software (coordinate value calculation) and automatic programming software. Automatic programming software is used for programming more complex drawings.
