Solutions to 5 common problems in tapping machines
①The solution to the broken tap
Correctly select the diameter of the threaded bottom hole for tap breakage; sharpen the inclination of the blade or use spiral flute taps; drill the bottom hole depth to meet the specified standard; appropriately reduce the cutting speed and select according to the standard; correct the tap and the bottom hole when tapping, Ensure that its coaxiality meets the requirements, and use floating tapping chucks; increase the rake angle of the tap and shorten the length of the cutting cone; ensure that the hardness of the workpiece meets the requirements, select the safety chuck; if the tap is worn out, it should be replaced in time.
②The solution to the tap collapse
Tap tooth collapse appropriately reduce the tap rake angle; appropriately increase the length of the cutting cone; reduce the hardness and replace the tap in time.
If the tap wears out too fast, appropriately reduce the cutting speed; reduce the rake angle of the tap and lengthen the length of the cutting cone; select a cutting fluid with good lubricity; perform appropriate heat treatment on the workpiece; sharpen the tap correctly.
③The solution to the tap wear too fast
If the thread pitch diameter is too large, choose a tap pitch diameter with a reasonable precision level; select a suitable cutting fluid and appropriately reduce the cutting speed; correct the coaxiality of the tap and the bottom hole of the thread when tapping, and use a floating chuck; appropriately reduce the rake angle and cutting Cone angle; remove the burrs produced by the sharpening tap, and appropriately increase the length of the cutting cone.
④Solution to excessive thread pitch diameter
If the pitch diameter of the thread is too small, select the pitch diameter of the appropriate precision grade; appropriately increase the tap rake angle and cutting cone angle; replace the excessively worn tap; select a cutting fluid with good lubricity.
⑤The thread pitch diameter is too small and the thread surface roughness value is too large, the solution
If the thread surface roughness value is too large, properly increase the tap rake angle and reduce the cutting taper angle; perform heat treatment to appropriately increase the hardness of the workpiece to ensure that the tap rake surface has a lower surface roughness value. Choose a cutting fluid with good lubricity; appropriately reduce Cutting speed; replace worn taps
Seven reasons why the tapping machine is unstable
1: The tapping tip of the gear tapping machine is worn or the spring is loose. Check whether the tapping tip of the gear tapping machine is worn or not causing uneven force, and then check whether the spring is too loose or replaced with a new spring.
2: The adjustment of the tapping belt of the tapping machine is not tight enough or the belt is damaged causing slipping. If the tapping triangle belt of the tapping machine is too loose, adjust the adjusting screw at the back of the machine to a proper state or change the belt.
3: The tapping belt of the tapping machine is too loose. Loosen the four small screws that fix the tapping machine, then press the tapping machine down, and then tighten the four screws.
4: The brake electric power of the clutch is bad, you can change the brake pads or replace the tapping machine.
5: The micro switch is broken, replace it with a new one. (How to replace the micro switch to be continued)
6: The cam stop switch position is wrong. If the start is too slow, the tapping machine will become unstable.
7: Material deformation or excessive residue in the chuck. Check the material more and clean the chuck more.
The main points of tapping machine:
1. The position of the workpiece clamp should be correct. Try to make the center line of the threaded hole in a horizontal or vertical position, so that it is easy to judge whether the tap axis is perpendicular to the plane of the workpiece.
2. The hole of the threaded bottom hole on the workpiece should be chamfered, and both ends of the through hole thread are chamfered.
3. At the beginning of tapping, try to position the tap as much as possible, then apply pressure to the tap and turn the twister. When cutting 1-2 turns, carefully check and correct the position of the tap. Generally, when cutting 3-4 turns of thread, the tap position should be correct. In the future, only need to rotate the twister, and no pressure should be applied to the tap, otherwise the thread profile will be damaged.
4. When tapping, every 1/2-1 turn of the twister should be turned, it should be reversed about 1/2 turn, so that the chips can be easily discharged after breaking, and it can reduce the phenomenon that the cutting edge is stuck due to sticky chips.
5. When tapping the screw holes of plastic materials, add lubricating coolant. For steel materials, rapeseed oil or molybdenum disulfide, etc. are generally used in organic or concentrated emulsions. For stainless steel, 30# engine oil or sulfurized oil can be used.
6. When tapping a screw hole that is not possible, always withdraw the tap to remove the chips in the hole.
7. When changing to the next tap during the tapping process, first screw it into the tapped and thread by hand, and then use the twister to turn it when it can no longer screw in. When the end taper is finished tapping and withdrawing, it is also necessary to avoid turning the wringer quickly. It is best to unscrew it by hand to ensure that the quality of the tapped thread is not affected.
8. When tapping, the tap and the screw hole must be coaxial.
