How do ST threading taps form internal threads and simultaneously compress material to enhance connection strength during the tapping process?

ST threading taps, through a "cut-then-extrude, extrusion-based" forming mechanism, not only efficiently form internal threads during the tapping process but also significantly enhance connection strength through the plastic deformation of the material.

How does the surface coating of special taps for aluminum enhance its wear and corrosion resistance?

The CrN coating reduces chip evacuation difficulties in long cutting paths through its anti-stick properties.

Why must machine-used ST threading taps possess torsional strength for automated tapping?

In automated tapping systems, machine ST threading taps are no longer simply cutting tools; they become "high-risk nodes" in the entire production chain. Their torsional strength is directly related to machining yield, equipment safety, and production cos

What effect does the chip groove structure of spiral point taps have on chip breaking during continuous cutting?

During the continuous cutting process, the coolant not only plays a role in cooling, but also changes the stress state of the chip by impacting the chip surface.

Are the cutting edge sharpness and land width of spiral flute taps balanced?

In modern metalcutting, taps are the core tools for thread forming, and their performance directly impacts thread quality, machining efficiency, and tool life.

How do machine-used ST threading taps achieve efficient chip evacuation through their special flute design?

Through a scientific and specialized flute design, machine-used ST threading taps achieve efficient chip evacuation, becoming a key technology for ensuring machining stability and production efficiency.
