Question 1

What is magnetic polishing?

Accepted Answer

Magnetic polishing is a surface finishing process that uses a rotating magnetic field to drive stainless steel pins against metal workpieces. It efficiently performs deburring, polishing, de-oxidizing, and inner hole finishing on complex geometries — all without manual labor. It's widely used in automotive, aerospace, medical device, jewelry, and electronics manufacturing.

Question 2

What metals can be polished with magnetic polishing machines?

Accepted Answer

Magnetic polishing machines can process a wide range of metals including gold, silver, brass, copper, aluminum, 304 stainless steel, titanium alloy, and zinc alloy. They are suitable for both precious metals in jewelry and industrial metals in precision manufacturing.

Question 3

What is the difference between magnetic polishing and mirror polishing?

Accepted Answer

Magnetic polishing uses magnetic field-driven stainless steel pins for deburring, cleaning, and surface finishing of complex parts. Mirror polishing uses natural plant particles (olive/walnut shells) in a dry process to achieve a reflective, mirror-like surface finish. Magnetic polishing is ideal for functional finishing while mirror polishing is for decorative, high-gloss applications.

Question 4

Who is Precinova and what do they offer?

Question 6

How do I choose the right magnetic polishing machine size?

Accepted Answer

Machine selection depends on your workpiece size and batch volume. Desktop models like GG8520 (8–10 KG capacity) suit small workshops and jewelers. Mid-range models like GG8850 (20–30 KG) handle medium batches. Industrial models like GG2380 (50–70 KG) and GG2980 (60–80 KG) are designed for high-volume manufacturing. Contact us for a personalized recommendation based on your specific application.

Question 7

How does magnetic polishing compare to vibratory finishing?

Accepted Answer

Magnetic polishing uses a controlled magnetic field to drive stainless steel pins, making it far more effective for complex geometries, inner holes, and delicate parts than vibratory finishing. Vibratory machines use bulk media tumbling, which can damage thin or intricate components. Magnetic polishing is faster (typically 5–15 minutes per cycle), produces no dust or noise, and delivers a more uniform surface finish. It's the preferred choice for jewelry, medical devices, and precision-machined parts.

Question 8

What is the price range of magnetic polishing machines in India?

Accepted Answer

Magnetic polishing machine prices in India vary based on capacity and configuration. Compact desktop models suitable for jewelers and small workshops start at a lower price point, while industrial multi-station machines for high-volume manufacturing are at the higher end. Precinova offers the complete Guangu Tech range with competitive pricing, installation support, and after-sales service.

Question 9

Which polishing machine is best for jewelry making in India?

Accepted Answer

For jewelry polishing, the GG8520 magnetic polishing machine is the most popular choice. It handles gold, silver, brass, copper, and platinum with a compact desktop footprint ideal for workshops. It performs deburring, polishing, de-oxidizing, and inner hole finishing in a single cycle — typically completing a batch in 5–15 minutes. For higher volumes, the GG8620 and GG8720 offer larger capacities while maintaining the precision required for delicate jewelry pieces.
