Attention those struggling with improving flatness accuracy through conventional polishing! Try our lapping process.
Our company can perform processing while preventing the generation of processing stress through wrapping processing technology.
The one-sided wrapping machine "PLR-420S" adopts a hydrostatic bearing structure in the rotating part of the base plate, allowing for smooth rotation without stick-slip phenomena or vibrations, and it also requires less polishing drive power, featuring an energy-saving design that considers the environment. The "PLR-420S" is one of the largest sizes among large one-sided wrapping machines, capable of processing work sizes that were previously impossible to wrap. 【Features】 ○ Wet processing minimizes thermal impact on the workpiece, resulting in less processing distortion. ○ Processing is done without clamping the workpiece, so no excessive force is applied, leading to minimal changes in long-term accuracy after processing. ○ Flatness that could not be achieved with turning, machining, or grinding can be attained with wrapping processing. ○ By performing wrapping processing on the reference surface before precision finishing (grinding, machining), a high level of finishing can be achieved.

basic information
【Features】 ○ Equipped with slow start and slow stop functions using inverter control for the rotation control of the flat plate. → Together with the static pressure hydraulic bearing structure, it can prevent localized stress on the workpiece that occurs during the start of the lapping process. ○ The facing device adopts a 2-axis CNC system. → Allows for precise correction during the precision correction processing of the lapping plate's upper surface. → By intentionally shaping the lapping plate into convex or concave shapes, it is possible to create not only flat surfaces but also convex and concave surfaces on the workpiece. 【Specifications】 ○ Size: 165 inches (Lapping plate diameter 4200mm) ○ Maximum processing size → Coating head type: Up to 2600L (Flatness and parallelism within 5μm) → Square type: Up to □2100 (Flatness and parallelism within 10μm) → Round type: Up to φ3000 (Flatness and parallelism within 10μm) ● For more details, please contact us or download the catalog.

Company information
The expression "ten nines" is used to represent the high purity of metals. While it is incredibly close to zero, in the world of semiconductors, it is said that just picking up a material with a purity of ten nines equivalent to the size of a single caramel can reduce its purity to about six nines (99.9999). Such a fine world is represented by the figure of ten nines. We, at OKD Corporation, as a group of technical experts engaged in ultra-fine processing, will always maintain the aspiration of ten nines. From prototype development to mass production of ultra-fine finishing, we respond with total technology.
