Tophammer drilling
Together these elements make it possible to drillholes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction and quarrying of rock material.
Top hammer drilling principle
1. When the piston hits the shank, kinetic energy in the piston creates a compressive wave in the string of drilling tools, that will cause the bit to penetrate the rock
2. Piston velocity at impact ≈ 10m/s but the compressive wave in the drill steel travels at a velocity of 5180 m/s (velocity of sound in steel)
3. The bit is forced forward and penetrates the rock around 1.0 mm
4. Part of the energy not used to penetrate the rock goes back as a tensile wave and part of it as a compressive wave
Product advantages
Sollroc tophammer drilling tools has advantages as follows:
1. Material are developed by cooperated with National & Local Joint Engineering Laboratory for High-performance Metal Structure Materials and Advanced Manufacturing Technology to improve the fatigue resistance of drilling steel.
2. Material is from Baosteel with strict process of steel smelting and rolling: Refining - Vacuum - Continuous casting - drilling hole method - surface peeling to control the content of non metallic inclusion and harmful element.
3. Strictly control precision thread process to avoid thread too hot and broken effected by the high vibration and shaking of thread part when it works.
4. Heat treatment: Fully Carburization - Air cool quenching - tempering. It make the rod keep high toughness and improve surface harness and whole strength as well.
5. Thread strengthen: enhance the thread parts to improve the wear-resistance and longevity of the rod.
