CNC Knowledge: Three ways to treat threads for the CNC machining center

The advantages of the use of the treatment part of the CNC treatment center have been deeply understood that there is still a mysterious sail for the operation and programming of the CNC treatment center. Today, Chenghui Xiaobian will share with you the wire treatment method. Methods: Method of threading the thread and treatment of treatment, and selection of the treatment method: Thread milling method:
1. The crushing milling method is used to use threaded milling tools for the treatment of large pores threads.

1. The tools are generally hard alloy materials, rapid speed, high speed threads and high treatment efficiency;

2. The same distance from thread, whether it is a thread on the left or a right rotary thread, can use a set of knives to reduce the cost of the tool;

3. Threads milling method is particularly suitable for treatment of stainless steel and copper wire, which is difficult to treat materials.

4. Without the front end of the knife, it is more practical to treat the blind hole with a shorter thread or the hole without the groove of the knife.。

The threading grinding tools are divided into two types: Tightening machine the lash shot in hard alloy and the global hard alloy striker. ; And the overall hard alloy striker is used to treat the hole with the length of the wire less than the length of the tool;

Note for the CNC programming for threads: so as not to cause damage or processing errors in the tool.

1. After treating the holes at the bottom of the thread, use the forest to treat the small diameter of the diameter and use a large hole with a large amount of machining to ensure the precision of the lower hole of the thread;

2. The tools are generally cut and cut off from the 1/2 -tone arc trajectory to guarantee the shape of the wire.

2. CNC Center TAP treatment method is applicable to thread holes with a small diameter or a low position accuracy requirement. which can reduce margins treatment waste.

You must choose the appropriate tap depending on the materials processed.

It is very sensitive to treated materials; The wire cannot guarantee the depth of the treatment of the wire. The width of the quartet.

The programming method is relatively simple.

Third, the method of processing the selection deduction

The treatment method is suitable for the treatment of large thread holes on the parts of the box, or this method is adopted without crushing and threaded striker. There are the following precautions for the implementation of the implementation method:

1. Start the pin to have a delay time to ensure that the main axis reaches nominal speed;

2. The grinding of the blade of the knife with hand grinding cannot be symmetrical and the inversion retreat cannot be used. knife;

3. The knife rod must be accurately compatible with the position of the knife groove, otherwise the treatment of the multi-douce rod cannot be used, causing a random loop;

4. Pressure when you choose the loop, you shouldn’t be able to pick it up in a sword.

5. The processing method is only suitable for special thread distance threads without corresponding tools, and the processing efficiency is low.

The CNC treatment center which picks the treatment method is only a temporary emergency method.
