How does the chip groove design of spiral point taps balance chip removal and strength?

When processing high-hardness materials such as 40Cr that have undergone quenching and tempering, the helix angle should be appropriately reduced to enhance the cutting edge strength.

What effect does the cutting cone angle of a pipe thread tap have on the cutting force?

The cutting cone angle of the pipe thread tap is one of the core parameters in tool design, and its size directly affects the force distribution, tool life and machining quality during the cutting process.

How does the cooling method of special taps for aluminum affect processing stability?

Coolant reduces the formation of oxide layers and lowers burr height through cooling and flushing.

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
