CNC Knowledge: Injection wire marks, poor angle cleaning, deformation … How to solve problems of slow wire treatment?

1. How to reach wireless marks at the entrance?

(1) appearance
In and out of the arc

(2) Inner hole
1) You can use a cutting tool from pointed corners, and the hole originally can be changed into an open type
2) Adjust the power line of each knife in a different position, try not to shake too much

2. How to make the angle (erase the angle) and what are the methods?

There are two ways to clean the corners:

1) Clear graphics angle
Cleaning the corners of the figure means treating the figure in advance and drawing the corners of the figure.

2) Angle of clearance of the amount of the compensation
The compensation clearance angle consists in pouring a very small R angle at the sharp corner of the concave, approximately 0.09 mm (line of 0.25 mm). reached.

3. How to prevent deformation?

(1) Prevent deformation first of all, the material must not have an internal constraint, in particular the internal constraint of the soaked material is relatively large, it must therefore be tempered and removed.

(2) preventing it from air -cutting treatment technology.

1) Select the starting position and the appropriate support position. If you choose in an inappropriate place, after thickening, the part in support of the material will become fragile and distorts accordingly. If you choose a place where the support part is stronger after opening the thickening, it is true.

2) Do more support. Especially when you cut punches, inserts, etc., if you meet large or long parts, you must provide several supports instead of one, which can effectively prevent deformation.

3) When cutting the shape, if the wire is pulled in the wire, the thread cut into the hole of the wire will be considerably improved.

4. How to make the coherence of the upper, medium and lower dimensions of high thick materials?

High parts should be the same as the upper, medium and lower dimensions:

1) Increase the thread removal speed and increase the wire voltage a little

2) When you repair the first knife (forming the knife), repair it several times, that is to say repair the first knife several times (because this knife is mainly made of molding, and the one behind it is repair the finish)

3) If it is convex or concave, most of the machine tools can be adjusted in the electrical parameters (generally adjusting the SV seriv-tension)

4) If the cut is conical (one end is large and the other end is small or reverse), you can use a cone to compensate, that is to say, add the cutting cone to the program (generally 0.002 MM)

5. How to make a treatment without a chip and what are the methods?

There are two ways to treat without a chip:

1) Some wire cutting software has this function, which winds the coil directly in the hole.

2) During programming, cut more and use corrections to control.

6. What are the methods of treatment of wireless heads?

1) When you cut the shape, once the knife is finished, connect the copper sheet, then place the glue. This method is for small or larger parts are generally not recommended.

2) That is to say secondary tightening. For small pieces per lots, you can cut the light holes, which will effectively improve efficiency.

7. What should I do when cutting the precision terminal mold to ensure precision and position?

When you cut precision molds, especially the models, you must first do the overall thickening, that is to say that you must first cut all the holes without repairing them. Then, make a fine crushing on the flat surface, because when the thickening is made, the surface of the model will be slightly deformed, and finally all will be refined.

8. The male and female molds are shared and the dismantling plates are shared.

Common to male and female molds: (a quantity of compensation to a cup x2 side deviation) / (thickness of the plate – male mold slice – point to point of mold), it should be noted that in normal circumstances, The cone is reversed cut.

There are two forms of internal and external sharing:
1) Step -by -step style (use this mainly)
2) Angle control, this is similar to that of male and female models, but there is no right body
