1. During threaded blind hole processing, incomplete threads appeared.
To reduce incomplete threads, using a thread mill or tap with a shorter cutting taper length is key.
2. How to process the bottom hole of the extrusion tap?
Use carbide drill bits (smooth-edged drill bits with rollers, etc.) that are more precise than traditional high-speed steel drill bits.
For small-diameter holes, it is recommended to use a high-precision drill bit with a drill bit diameter that is accurate to a hundredth.
After using a drill for bottom hole machining, it is very effective to use an end mill for contouring and boring cutting.
3. Processing small diameter threaded holes
Using a small-diameter thread milling cutter can break chips into fine pieces, enabling stable small-diameter threaded hole machining.
Use extrusion taps for plastic processing.
