COMMON ORBITAL SANDER ISSUES & SOLUTIONS 30/8/2023
COMMON ORBITAL SANDER ISSUES & SOLUTIONS The right sanding job is essential to getting a high-quality finish. Orbital sanders work by elliptically rotating a sanding disc so that it never travels over the same area twice, leaving a smooth surface with no swirl marks. Random orbital sanders, in contrast, spin in circles and orbit in an elliptical motion, reducing swirl marks and leaving random scratch patterns.

Although orbital sanding is not complicated, keeping certain things in mind can help you avoid common problems and achieve the best finish. In this blog, we'll discuss common orbital sander issues and provide solutions. SANDER WON’T COME ON In most cases, a motor problem will prevent the sander from running, so if your electric orbital sander stops spinning completely, it might not have a working motor. You should be able to make the sander run again by disassembling it and replacing the motor. Before you make any repairs yourself, you should check to see if your sander has a warranty. The warranty may cover motor issues if the sander is still relatively new. You can contact the manufacturer to inquire about warranty coverage. SPINNING ISSUES A common problem with orbital sanders is that they suddenly stop spinning. There are some particular reasons for this, which are highlighted below. #1. ROTOR PROBLEM (FOR ELECTRIC ORBITAL SANDERS) The rotor contains wires that run the electricity needed for it to rotate. These wires can burn if the voltage is too high or the motor is doing heavy-duty work for a prolonged period of time. When this happens, the entire motor stops working and the orbital sander won’t spin at all, making repairs or replacement necessary. #2. SHAFT PROBLEM (FOR PNEUMATIC ORBITAL SANDERS) The rotor is rotated by air hitting its blades. If the shaft becomes damaged and deformed due to heavy usage or rust build-up, it won’t be able to balance the rotor and the bearings. When this happens, your orbital sander will eventually stop spinning, so you’ll need to replace the shaft to get it working again. #3. BEARING PROBLEMS (BOTH PNEUMATIC AND ELECTRIC ORBITAL SANDERS) The bearing located on the bottom plate keeps the disc rotating. Other bearings inside the body of the sander transmit force on the bottom bearing to help with rotation. However, if the bearings are damaged by rust, the disc will not spin properly. Bearings tend to rust when water enters the sander, although other known causes include exposure to high humidity and long periods of disuse. To confirm that this is the issue, disassemble the sander to see whether the bearing is damaged. If it is, replace it with a new one.
