Magnetic Polishing Machine GG8720

The GG8720 is the mid-range workhorse of the Guangu Tech lineup. It has a 500 mm round polishing bucket and a 4 KW motor. Each batch handles 15–18 KG. This suits automotive shops, electronics makers, and general engineering workshops.

A big upgrade on this model is the voltage display meter. It lets you check the 380V power supply before each run. This prevents motor damage from voltage drops, which are common in Indian factory areas. You also get forward/reverse magnetic field control, an auto-stop timer, speed adjustment, and fuse protection.

How does it polish? A spinning magnetic field pushes stainless steel pins against your parts at high speed. The pins remove burrs, polish surfaces, strip oxide layers, and clean inner holes. Part dimensions stay the same. Delicate features stay safe. Most jobs take 5–20 minutes. Read more about how the technology works.

The machine weighs 218 KG. It is strong enough for daily industrial use. Add Fuma casters to move it around the shop. It handles gold, silver, brass, copper, aluminum, stainless steel, titanium, and zinc alloy.

You will find the GG8720 in factories across Pune, Chennai, Gurugram, Bengaluru, Ludhiana, and Coimbatore. Need more capacity? See the GG8850 with its square bucket design. Precinova provides setup, training, and genuine spare parts from Ambala, Haryana.
