The titanium alloy alloy tap (like TC4) is more difficult to treat more than most alloy materials, but it is always possible to choose the appropriate tap. The titanium material is hard and light, and is a very attractive metal that is suitable for aerospace, medical and other industries.
However, the characteristics of the titanium alloy have challenged many treatment plants, and many engineers are also looking for appropriate solutions for this material.
For example, titanium cannot be well done. During the treatment of titanium, calories often accumulate on the surface and at the edges of the tool, rather than distributed by the structure of the parts and the machine. This is particularly true during the attack, because the contact between the inner surface of the hole and the tap cone is more contact with more contact between parts and exercises, vertical strawberries or other tools. This preserved heat can cause a gap in the cutting blade and shorten the lifespan of the tap.
In addition, the low elastic module of the titanium makes it “elastic”, so that the room “bounces” often on the tap. This effect can cause wire wear. It also increases the torque on the tap, shortening the lifespan of the tap (it is therefore not recommended to find second -hand tap cones imported here. Once the tap has undergone a strong torque, if the risk From the tap cone will be excellent, it will be very large.
In order to obtain the best results when attacking the titanium alloy, please use the dedicated brand tap, install it in the handle of the attack wire and select the appropriate settings on the machine tool with Good feeding control.
1
Use the appropriate speed
The attack speed is essential to cut the titanium alloy threads. Insufficient or too fast will cause a failed tap and shorten the lifespan. To enter and leave the wire holes, it is recommended to refer to the brand sample here to use a reasonable attack speed. Although it is slower than most other materials, this series has proven to provide the lifespan of the most coherent tap and maximum productivity.
2
Use the appropriate cutting fluid
The cutting solution (cooling / lubricant liquid) can affect the lifespan of the tap. Although the same cutting fluid used in other titanium alloy operations is a choice of attack wire, this cutting liquid does not necessarily produce the quality of the wire and the lifespan required. We recommend that you use high quality emulsion with higher oil content or better use of attack oil.
In the attack wire, the lubrication characteristics of the cutting fluid are generally greater than cooling, because the tap operates at a relatively low speed without eliminating a lot of materials. Lubrication helps prolong the lifespan of the tap and protect the surface of the wire.
Titanium alloy difficult to treat may need to use attack silk cream containing additives. These additives are designed to join the cutting surface, although high treatment is generated on tools and parts interfaces. The disadvantage of the attack cream is that it must be applied manually and that it cannot be automatically applied by the machine cooling system.

Use CNC CNC
Although any machine tool that can treat titanium alloy should be able to effectively attack these materials, CNC machine tools are most suitable for titanium. Generally, this more recent equipment provides circulation of rigid attack wires (synchronous).
The old CNC unit generally does not have this function. In addition, these former equipment are not good, and it is not recommended to attack, because the attack is a specific treatment, and the choice of equipment is still a little special . is a problem to cut the knife, so this owner of the company must also be careful.

Use the attack handle
The tap is particularly vulnerable, which will reduce the quality of the wire and shorten the lifespan of the tap. For this reason, a high performance attack handle should be used to provide rigid parameters. The circulation of rigid / synchronous attack wire is possible at the CNC machining center, because the rotation of the main axis can be synchronized with precision with the axis of the tap in the hour and time direction in the hour .
This capacity allows a wire without long compensation in the tap.
Some attack handle stems are designed to compensate for a minor synchronization error which can occur even in the best CNC device (it is recommended to choose the brand’s attack handle).

About tightening
In order to obtain the highest accuracy and repeatability, check the lighting of your parts to make sure that your file retention system can be fully fixed on the part. This proposal is particularly important for small lots processing workshops and large -scale car production factories.
Many of these pieces have thin walls and complex characteristics, which are conducive to vibrations. In these applications, rigid parameters are conducive to each processing operation, including attack wires.
For these reasons, we recommend that you cooperate with your work file provider so that they can clearly understand the current problems. This will help avoid poor communication and reduce the overall costs of the project.

Plan in advance to determine the requirements of attack wire equipment
The life of the cone depends on many factors, including the capacity of the machine, the precision of food control, the quality of the attack handle, the note of the titanium alloy, the type of coolant or lubricant.
The optimization of all these factors will ensure that attacking the attack is effective.
During the titanium attack, a good experience is: for a hole with twice the depth of its diameter, each attack should be 250 to 600 holes. Maintain a good file to monitor the lifespan of the tap. (Of course, whatever the type of equipment you are treated, it is always important to use new tap cones to participate in the treatment.)
The accidental change in lifespan may indicate that key variables must be adjusted. The problem of the attack operation may also indicate a negative impact on other operations.
In the end, the publisher had to say a few words. Since titanium materials are generally more expensive, overall investment in raw materials and a large quantity of value treatment will increase the overall cost.
