オーケーディー List of Products and Services

We accept consultations regarding flatness accuracy, surface roughness, and other requests using our wrapping machine. Our "PLR-420S" is one of the largest single-sided wrapping machines, capable of processing large workpieces. If you are facing issues such as "unable to achieve flatness accuracy with grinding machines" or "unable to meet surface roughness requirements," please feel free to contact us directly. 【Features of Wrapping Processing】 - Wet processing minimizes thermal impact on the workpiece, resulting in less processing distortion. - Since the workpiece is processed without being chucked, it is less likely to experience processing stress, leading to minimal changes in accuracy over time after processing. - Flatness that cannot be achieved through turning, machining, or grinding can be accomplished with wrapping processing. - By performing wrapping processing on the reference surface before precision finishing (grinding, machining), high-performance finishing can be achieved. *For more details, please refer to the PDF document or feel free to contact us.

We utilize ultra-finishing techniques centered on polishing to achieve ultra-fine and ultra-smooth surfaces required for coating heads used in FDP and various film and battery manufacturing equipment. Materials such as SUS can be manufactured. The desired precision is guaranteed by our processing technology. For delivery times, we can accept partial contracts for each process. For example, we can shorten the time by only performing polishing or only machining! 【Precision List】 ■ Total Length: 4000mm or less ■ Tip Straightness: 0.001mm to 0.010mm or less ■ Inner Surface Flatness: 0.001mm to 0.010mm or less ■ Tip Surface Roughness: 0.1S or less ■ Inner Surface Roughness: 0.05S to 0.2S or less We are currently offering a document summarizing points to confirm when requesting coating heads (die coaters)! *For more details, please contact us or download the catalog.

• Wafer processing/polishing equipment

We would like to introduce a case study of a problem-solving example for polishing samples conducted by OKD. The drawing specifies a surface roughness of 0.2s and flatness of 0.005mm or less. While grinding is not feasible, we achieved this with lapping processing. Our company uses lapping machines and is open to consultations regarding flatness accuracy, surface roughness, and other requests. If you are facing issues with high precision and high quality, please feel free to contact us. 【Are you facing any of these issues?】 ■ Unable to achieve flatness accuracy with grinding machines ■ Unable to meet surface roughness requirements We will provide you with a document summarizing key points you may want to confirm before placing an order! *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

It was introduced to achieve ultra-smooth surfaces of large components, represented by liquid crystal-related materials. By incorporating a non-contact variable static pressure sliding system, ultra-high precision of 0.8μm over 2,000mm is realized. 【Specifications】 ■ Processing range (X/Y/Z) 4000mm/550mm/600mm ■ Flatness of reference surface Longitudinal direction 0.4 micrometers/600mm Lateral direction 0.5 micrometers/1000mm

• Processing Contract

We own a wide variety of processing machines and measuring instruments, allowing us to carry out arrangements, machining, grinding, polishing, and measurement in-house with minimal outsourcing. This also helps us avoid temperature changes caused by workpiece movement and exposure to outside temperatures, leading to shorter delivery times and reduced temperature stabilization time during precise measurements, enabling us to respond "quickly." 【Specifications】 ■ Table size: 2100mm × 4000mm ■ Movement range (X/Y/Z): 4000mm × 3600mm × 710mm × 1250mm ■ Movement range (A/C): ±100°/±180°

• Processing Contract

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.
