Atlas Copco Secoroc knows a thing or two about rock. Our earliest experience of mining and steel dates back to the 15th Century. In the intervening 600 years we like to think we've acquired a measure of expertise - a fact perhaps best reflected by our history of innovation and our comprehensive selection of rock drilling tools. Over the years Atlas Copco Secoroc has met the needs of mining and construction companies, quarry and water well drillers the world over with products such as Secoroc tapered equipment, Magnum SR drifting equipment, the COP 64 Gold hammer and the Grind Matic BQ2 and BQ2-DTH grinding machines.
The trend in tunnelling and drifting is clear: the hydraulic rigs are ever more powerful and the rounds longer. Naturally, this places rigorous demands on drillstrings. Enter Secoroc Magnum SR, the next generation of drifting equipment. The key is a patented design; the rods and bits may look like standard drifting equipment but the thread is actually conical in shape. For example, the Magnum SR35 thread has a rod end diameter of 35mm, while the tip is 32mm. This means more material at the rod end to prevent breakage and less tendency for deviation when collaring. There are currently three models available: Magnum SR28, and SR35 and the Magnum SR Straight for exceptionally straight holes.
Secoroc COP 64 Gold is without a doubt one of the most reliable hammers we’ve ever built. The piston with a polygon shape, combined with milled slots in the cylinder, has greatly enhanced guidance. That means less internal wear with sustained efficiency and productivity throughout the life of the hammer. The cylinder is made of a special high strength steel, developed specifically for rock drilling applications. Built to stand up to abrasion, the hammer can even be pushed below current wear limits. What's more, the 12-spline chuck stands up better against spline wear. More than a million metres of test drilling have shown that drillers can look forward to a 30% to 50% longer service life compared to the previous genration.
The new Secoroc Grind Matic BQ2 and BQ2-DTH are two exceptionally efficient grinding machines. Grind Matic BQ2 has been specially designed for threaded and tapered bits with spherical and ballistic buttons. And, as the name implies, Grind Matic BQ2-DTH is a semi-automatic grinder for both DTH and COPROD bits with spherical as well as ballistic buttons.
On both machines, grinding capacity has been upped considerably thanks to numerous novel features.
A good example of innovative design is our new grinding spindle which facilitates rapid change of grinding wheels with no tools needed. As an added bonus, both grinders feature an automatic centering arm and indexing bit holder too. With optional equipment, Grind Matic BQ2-DTH, can also grind threaded bits.
