Metal Surface Polishing Machine: Domestic Development and Domestic vs. International Technology Comparison

2025-11-181009

As high-precision surface treatment equipment, the technical level of metal flat polishing machines is directly related to the product quality of high-end industries such as mobile phones, automobiles, and aerospace. After decades of development, China's industry has gradually transformed from a technology follower to a parallel player, demonstrating unique competitiveness in the global market.

Domestic Development History of Metal Flat Polishing Machines
China's metal flat polishing machine industry started in the late 20th century and has undergone three stages of leapfrog development.

Before 2005: Embryonic stage. Equipment was mainly manual and semi-automatic with low technological content, primarily meeting the simple polishing needs of basic manufacturing industries such as mobile phones and home appliances. During this period, the industry output was about 50,000 units, and the market size was only 800 million yuan.
2005–2015: Golden growth stage. Benefiting from the rapid expansion of domestic manufacturing, market demand continued to release. The industry output soared to 500,000 units, the market size exceeded 8 billion yuan, with a compound annual growth rate (CAGR) of 13%. Automatic equipment began to gradually replace traditional manual equipment.
2021–present: High-quality development stage. In 2024, the market size reached 12 billion yuan, the proportion of intelligent equipment continued to rise, and the precision polishing demand from high-end fields such as new energy vehicles, aerospace, and high-end electronics has become the core driver of industry growth.

Domestic vs. International Technology Comparison of Metal Flat Polishing Machines
Currently, the domestic and international metal flat polishing machine technologies show a pattern of "partial catch-up and overall gap."
International giants such as Kemet (UK), Sokei (Japan), and Lamart (USA), as well as domestic high-quality manufacturers such as Tengyu and Heruite, hold obvious advantages in core areas such as ultra-precision control, multi-material compatibility, and long-term operation stability. Their equipment can stably achieve ultra-precision polishing effects of Ra 0.0005μm, compatible with more than 15 metal materials with different characteristics. The supporting intelligent system has a built-in library of 1,000 sets of process parameters, enabling rapid adaptation to different processing needs.
However, overall, core components of domestic high-end equipment (such as PLC, frequency converters, touch screens, and other core control systems) still rely on imports. There is a gap between polishing consumables under complex working conditions and the international advanced level. Currently, international brands still account for 20% of the domestic high-end market share.
