Low vibration values

Precise small grinders for coarse and fine grinding

Atlas Copco Tools has revised its small grinder series. The tools in the LSF 29 series, which are suitable for processing both coarse and fine surfaces, have vibration values below the EU directive limit.

The new LSF 29 sanders from Atlas Copco Tools are suitable for processing both coarse and fine surfaces. Compared to their predecessors (LSF 28), the new 29-series sanders offer at least 20 percent more power and significantly increased productivity, according to the company. The ergonomics of the tool are to be further improved. Various optimization measures have further improved the power-to-weight ratio, which significantly shortens machining times and drastically reduces operating costs. The 1 kW vane motor of the stick sanders has an integrated speed controller that keeps the speed constantly high, even with comparatively high pressure against the workpiece. This means that the sanders always work at the optimum speed and efficiency.

A natural position is always the most comfortable. The handle and starter must therefore be well thought out. Thanks to the handy handle design and the ergonomically designed safety starter, the LSF-29 tool sits comfortably in the hand and its good grip ensures reliable and safe operation. The extended E versions also have effective additional vibration damping of the spindle, which is guided by a robust triple ball bearing. The rubberized housing in the spindle area contributes to the smooth running.

Vibrations below 2.5 m/s2
The special pendulum bearing reduces the vibration values significantly below the current limit value of 2.5 m/s2 in accordance with EU Directive 2006/42/EC. This reduces the risk of vibration-related illnesses. In addition, the pendulum bearing allows milling cutters to be guided better, which practically eliminates the "dancing" of the mounted points on the workpiece surface. The total of 17 rod and straight grinders in the LSF-29 series cover practically all areas of application in metal and material processing in different long and short housing variants and with speeds from 3,000 rpm to 25,000 rpm.
