he Ø15 mm orbit and the RUPES Ø125 mm backing pad make the random orbital polisher particularly suitable for curved surfaces. The 15mm orbit of the LHR 15ES, shorter than that of its big brother the LHR 21ES, is coupled with a higher rpm level than that of the LHR 21ES. This higher speed gives the LHR 15ES equivalent cutting power to the LHR 21ES, in spite of the smaller orbit. Its Ø130/150 mm BigFoot polishing foam pads, perfect balance and vibration-free operation make the LHR 15ES a real gem and a must for the tool kit of every detailer.
RANDOM ORBITAL: the backing plate follows an orbit (the amplitude of which depends on the distance between the rotation axis of the drive shaft and the central axis of the backing plate) and is free to rotate about its own central axis. The backing plate is free to rotate at varying velocities and directions by effect of the centrifugal force of the offset movement and by effect of friction. Should the friction forces be such as to prevent rotation of the disc while the tool is still operating, the random orbital movement would simply become an orbital movement. The number of disc rotations is variable and independent of the number of orbits performed. The random orbital movement is at present the best compromise in terms of effectiveness and surface treatment quality.
