Explanation of Forced Rotation of the FLEX XC 3401

FLEX XC 3401 VRG Orbital PolisherThe FLEX XC 3401 VRG is an orbital polisher with forced rotation. What is forced rotation? Let’s compare it to a polisher without forced rotation, like the Porter Cable 7424XP.

A Porter Cable 7424XP and the FLEX XC 3401 VRG are both described as orbital polishers, but there’s a noticable difference between these two machines. Both machines are constructed so that the pad rotates and orbits around the central spindle, but the FLEX features forced rotation.

To understand forced rotation, it’s helpful to think of a bicycle. The back wheel of a bicycle is connected to the chain and sprocket and it’s driven by the pedals. There’s a mechanism forcing the rotation of the back wheel. This is like the pad’s rotation on the FLEX XC 3401 Orbital Polisher. The front wheel of the bicycle is just along for the ride. It rotates when the bike is in motion but there’s no mechanism driving it. That describes the pad rotation on the Porter Cable 7424XP it rotates freely as it orbits because of a free spinning bearing assembly.

In practice, the forced rotation of the FLEX XC 3401 VRG and the free rotation of the Porter Cable 7424XP feel quite different. The FLEX pad completes full rotations and has a lot of power behind it to force that rotation. The FLEX XC 3401 VRG, even though it?s still an orbital machine, can remove a lot of imperfections. The Porter Cable?s motion is often described as jiggling, but it still achieves the dual action?that is, orbiting and rotating ? that will keep you from burning the paint. The Porter Cable 7424XP is great for minor defect removal, waxing, and general polishing.

New at Autogeek! 3M Electric Variable Speed Rotary Polisher

3M Electrical Variable Speed Rotary Polisher

You’ve relied on 3M polishes for years to give you professional results on auto finishes; now you can apply them with the new 3M Electric Variable Speed Rotary Polisher! The 3M Electric Variable Speed Rotary Polisher has a powerful 11 amp motor with 37.5% more power than 8 amp polishers. Superior construction and user-friendly features make the 3M Electric Variable Speed Rotary Polisher a true professional grade polisher.

The 3M Electric Variable Speed Rotary Polisher is a paint-correcting machine! It’s built for fast, effective removal of paint imperfections with the 11 amp motor and operating speeds of 1,000 – 3,000 rpm. The electronic variable speed control maintains speed and power even under load. The variable speed control trigger allows the operator to vary the speed below the selected maximum speed for greater control over polishing speed. Work at a slow speed for general polishing or speed it up for paint correction. A heavy duty trigger lock allows you to lock in your desired speed.

To make the 3M Electric Variable Speed Rotary Polisher more comfortable to use, 3M gave it an easy-grip flexible side handle that absorbs vibration. This reduces arm fatigue over the course of long detail jobs. There are three support handle positions to suit the job at hand. The polisher weighs just 7.9 lbs. but packs all the power of a much larger machine.
