New 18-Series Grinders from Atlas Copco
The power to get the job done – the new grinders from Atlas Copco are not only powerful but with a lubricant-free motor, they provide the same top power output day in, day out. In addition to this, operators get maximum rpm even when they push these grinders thanks to a built-in speed governor.
The 18-Series grinders come with a promise: once you have tried them, you are going to want them.
That’s what Rikard Lantz has found at Slip & Mekaniktjänst in Eskilstuna, Sweden. “They’re always the first tools off the shelves in the morning,” Rikard explains. Slip & Mekaniktjänst are subcontracted by companies such as ABB, Scania and Volvo to process aluminium castings, sometimes containing solidified chunks of sand. “If the grinders weren’t this powerful, it would take much longer to finish a job,” says operator Johan Fornstedt. “We really push them, but these tools are made to last.”
The 18-Series grinders are the same weight and size as their predecessors, but deliver almost double the power – 500 watts, for example – from a machine weighing just 0.5 kg. Despite the boost in power, there’s no increase in air consumption, or noise levels.
Motors that are improperly lubricated suffer from premature wear and drop in performance. But thanks to the new lubricant-free motor, owners of the 18-Series grinders can expect top performance day in, day out.
“The 18-Series feature a speed governor, which is unusual in tools of this size,” says Jörgen Karling, Product Manager. A speed governor ensures the high maximum rpm is maintained, even when operators push the grinders. “The speed governor is a real productivity booster,” Jörgen explains.
The series hosts a new system that overcomes temperature and leakage problems commonly associated with angle head tools. The solution is two-fold: a specially designed seal, plus a patent-pending cooling system. So confident are Atlas Copco of the effectiveness of the new design that they are backing it up with a five year guarantee.
The LSF straight models provide highly effective vibration dampening. The obvious advantage is the reduction of operators’ exposure to vibrations. But the cushioned action also prevents rattle and ricochet when working inside weld seams. This results in smoother, more productive grinding, plus lower wear on burrs.
Despite the high power of the new grinders, they are surprisingly quiet. Noise has been minimized in three ways. First, an all-new, patented motor design has resulted in a significant reduction. Noise levels have been further reduced by leading exhaust air through a silencer at the back of the tool. And finally, exhaust air is piped away in a hose, reducing noise still further.
The products and services range from compressed air and gas equipment, generators, construction and mining equipment, industrial tools and assembly systems, to related aftermarket and rental. In close cooperation with customers and business partners, and with more than 130 years of experience, Atlas Copco innovates for superior productivity. Headquartered in Stockholm, Sweden, the Group’s global reach spans more than 170 markets. In 2007, Atlas Copco had 33 000 employees and revenues of BSEK 63.
