| Zusammenfassung: | According to the invention, shrank mill formed by cutting part (1) and shank (2), where the cutting part (1) and shank (2) is formed helix (3). Outer diameter (D1) helix (3) is smaller than the diameter (D2) of the cutting (1), and helix (3) is formed by the notch (31) with an angle (alpha) climb less than 50 degrees. It is preferred that the cross-section groove (31) helix (3) in the direction of climb increases.
Stopková fréza podľa technického riešenia je tvorená reznou časťou (1) a upínacou stopkou (2), kde medzi reznou časťou (1) a upínacou stopkou (2) je vytvorená skrutkovica (3). Vonkajší priemer (D1) skrutkovice (3) je menší ako priemer (D2) reznej časti (1), pričom skrutkovica (3) je tvorená zárezom (31) s uhlom (alfa) stúpania menším ako 50 stupňov. Je výhodné, keď prierez zárezu (31) skrutkovice (3) sa v smere stúpania zväčšuje. |
