8 Splines COP1840 Forging Shank Adapter Alloy Steel With
Carburizing Technology
Description Of 8 Splines COP1840 Forging Shank Adapter:
The COP1840 shank adapter serves as a pivotal link in top hammer
drilling assemblies, engineered to integrate the COP1840 rock drill
with the drill string (comprising rods, couplings and bits). This
component efficiently channels kinetic energy, rotational force,
and drilling fluid to the string, optimizing rock penetration
performance.
Material Composition: Fabricated from premium alloy steel (e.g.,
chromium-molybdenum variants) to ensure exceptional tensile
strength and longevity.
Production Techniques: Undergoes carburization heat treatment and
precision CNC milling to bolster abrasion resistance and structural
integrity under cyclic stress.
Flushing Mechanisms: Configurable with internal or external
flushing systems.
