There are some problems during the tungsten carbide screw-tap’s is tapping, involving the  broken tap when processing or retraction. Look at the followings:

1.Tungsten carbide screw-tap’s selection is incorrect; Choosing the right conditions to be processed by the tungsten carbide screw-tap.

2.Encountering the bottom of the hole during the tungsten carbide screw-tap’s is tapping; Bottom depth examination.

3.Cutting excessive torque; Tapping shorten the length; using wire-tapping spiral groove.

4.Bottom is too small; Select the bottom hole diameter according to the corresponding standards.

It often occurs some problems when the tungsten carbide screw-tap’s is tapping, involving the thread is too large. There are several factors in the followings:

1.Tungsten carbide screw-tap’s selection is incorrect;

2.Eccentric Bottom;

3.Nonuniform axial feed;

4.Tungsten carbide screw-tap’s tolerance wrong choice;

5. Cutting speed is too high.

There are the solutions in the followings:
           
1.Choosing the right conditions to be processed by the tap

2.Tapping float switch / improvement Bottom

3.Tapping float switch / improvement tools

4.Reducing the number of tungsten carbide screw-tap’s chip flutes, flute expand capacity chip space;

5.Reduce cutting speed.

Some problems often occur when the tungsten carbide screw-tap’s is tapping, involving the high surface roughness of the inner thread. There are several factors and solutions in the followings:

1.Tungsten carbide screw-tap’s selection is incorrect; Choosing the right conditions to be processed by the tungsten carbide screw-tap.

2.Cutting speed is too high; Reduce cutting speed.

3.Cutting Cone length is not enough; Increase the length of the cutting cone.

4.Chip poor; Choosing the right conditions to be processed by the tungsten carbide screw-tap.

5.Bottom diameter is too small;    Select the bottom hole diameter according to the corresponding standards.

6.Cold welding; Improve the cooling and lubrication conditions.

Tungsten carbide screw-tap’ successful application depends on the stiffness of the tool holder and control precision feed. For most of the processing methods, these processing conditions for granted. But for tungsten carbide screw-tap’s tapping, these conditions are only just become a reality.

Machine control technology continues to progress, has been able to achieve with the rotation of the spindle synchronization control the feed, which can no longer use the soft tapping head. In addition, the use of thermal loading and hydraulic tool clamping chuck can increase the rigidity of the tool, but also significantly reduce run-out than when using flexible tapping head. Concentric rotation of the tool holder within 3μm. Despite the large clamping force precision telescopic precision (TGHP) chuck performance and less on heat-mounted hydraulic tool chuck, but when applied to tungsten carbide screw-tap’s tapping is also very effective.
