Cactus Materials, Inc. provides nano-level ultra-precision mirror polishing services to not only further improve the quality of our ceramic products, but we can also process other materials such as metals, glasses, resins, and semiconductor materials as well, on multiple types of surfaces (flat, spherical, cylindrical, etc.)

Ultra-Precision Polishing with Unparalleled Quality

Stainless 12-inch table, flatness 0.0008 mm, surface roughness less than Ra1nm

We can achieve precision in the nanometer ranges for size tolerance, surface roughness, flatness, parallelism, roundness, sphericity, and angle tolerance.

We have some of the world’s most advanced measurement equipment in-house, which is operated by highly skilled and experienced engineers who measure our products one by one. Our equipment includes Bruker’s AFM, Dimension Icon, and Mitutoyo’s CMM, LEGEX 9106. These devices are operated under strict temperature-controlled conditions. We provide the most reliable quality through our unrivaled technology, rich human resources, and unique production system.

Provider of Tailor-Made Solutions

Our success lies in providing tailor-made solutions per our clients’ needs. Because our polishing process shapes objects little by little, making reductions on a nano-digit scale, it allows us to achieve extreme precision for elements such as tolerance and surface roughness.
One such solution is our optimization of production. By improving the precision of one part, the assembly process becomes more stable and less error-prone, making it possible to optimize the production process and to eliminate unnecessary costs. We are ready and able to provide technologies that have previously been impossible to achieve these outcomes.

Why Precision Polishing for Rolls & Shafts is Necessary 

If you struggle with issues like damage and noise on the surface of a printing roll before patterning is applied, even after the cylindrical grinding process, precision polishing is the engineering miracle that will solve such problems. 
Recent advancements of high-performance films have contributed to the development of finer patterns and it is these finer patterns that brought about a new problem of increased NGs as subtle damage or noise, which used to be ignored, are now unacceptable.
Although the cylindrical grinding process also achieves mirror finishes, it does not satisfy the requirement for a perfect surface without any damage and imperfections.
