【Precision Grinding/Mirror Finish】Ultra-Precision Cylindrical Outer Diameter Polishing Processing
High-performance film, ultra-precision mirror rolls that enable further innovation in thin film manufacturing processes. Surface roughness achieves Ra1.5 nanometers!
Through TDC's ultra-precision polishing technology, we achieve nano-level surface roughness while maintaining dimensional accuracy and roundness. For example, are you struggling with substrate scratches before creating fine patterns on transfer rolls? Mirror finishing of the outer diameter of rolls and shafts. Surface roughness is achieved at Ra1.5nm and above. We realize a higher level of mirror finish! We accommodate from a single piece to mass production. Sizes can be accommodated up to a maximum of 2.5 meters. 【Supported Materials】 Stainless steel, titanium, aluminum, glass, various coated surfaces (nickel plating, chrome plating, hard chrome plating, etc.) <<< You can check the surface roughness inspection results of stainless steel and hard chrome plated surfaces by enlarging the image on the left <<< We also support other materials. Please contact us. ▼▼▼ We want you to know more about TDC's processing technology ▼▼▼ 【Free booklet 'Value Engineering with Polishing' available!】 ★ You can download the booklet and various catalogs from the catalog download button below ★ Surface roughness of around 1 nanometer is possible for most materials!!

Applications/Examples of results
TDC's ultra-precision mirror rolls have a proven track record of delivery to customers both domestically and internationally. By improving the mirror finish of metal rolls used in processes such as nanoimprinting, high-performance paper, film, thin film production, and the manufacturing process of nanoimprinting, we enable further quality enhancement in these processes. TDC's ultra-precision mirror rolls are already being utilized in various scenarios, including as practical components in equipment and for research and development aimed at enhancing the functionality of existing parts. Examples of delivery records: Domestic electronic device manufacturers (multiple companies), domestic material manufacturers (multiple companies), U.S. paper manufacturers, and others. In addition, we have received many inquiries from both domestic and overseas sources.

Surface roughness measurement results for stainless steel roll Surface roughness measurements have been taken in two coordinates: vertical and horizontal. Vertical) Ra 1.24 nm, Rz 8.69 nm Horizontal) Ra 2.4 nm, Rz 11 nm The larger surface roughness values in the horizontal coordinate are due to the incorporation of the curvature shape elements of the roll. Our company uses the vertical values for surface roughness evaluation. Measured with Taylor Hobson Talysurf CCI.

Surface Roughness Measurement Results - Hard Chrome Plated Surface Mirror finishing was performed after hard chrome plating. These are the surface roughness measurement results of the mirror finish. Vertical) Ra 0.74 nm, Rz 4.15 nm Horizontal) Ra 1 nm, Rz 4 nm The larger surface roughness values in the horizontal coordinates are due to the incorporation of the curvature shape elements of the roll. Our company uses the vertical values for surface roughness evaluation. Measured with Taylor Hobson Talysurf CCI.

Company information
We specialize particularly in ultra-precision mirror surface processing, with a maximum size capability of φ1500 for single-sided machines. We excel in improving flatness, parallelism, and surface roughness for precision stages and suction plates. For suction plates around φ300*10t, we produce with flatness of 0.001, parallelism of 0.001, and Ra below 0.01 (for SUS material). For φ100*5t (materials such as SUS, Ni, Ti, Mo, Ta, W, ceramics, Si, etc.), we can manufacture plates with precision of less than 0.001 in flatness and around Ra 0.001, which are used as ultra-high precision jigs and molds. ◆ Selected as one of the 300 vibrant small and medium-sized manufacturing companies in 2007. ◆ ◆ Chosen as one of the "Global Niche Top 100 Companies" by the Ministry of Economy, Trade and Industry in 2014. ◆ Selected as a "Regional Future Leading Company" by the Ministry of Economy, Trade and Industry in 2018.
