Standard Accuracy with Different Materials
(1)HCr-plated SCM material
| Finish | Precision class | Straightnes | Surface Roughness | R of Edge |
|---|---|---|---|---|
| Mirror | - | 30µm/1000mm | Ra0.03µm | 30µm |
| Super-mirror | - | 10µm/1000mm | Ra0.01µm | 20µm |
(2)Non-HCr-plated SKD material
| Finish | Precision class | Straightness | Surface Roughness | R of Edge |
|---|---|---|---|---|
| Grinded | - | 5µm/1000mm | Ra0.05µm | 5µm |
(3)Non-HCr-plated SUS630 material
| Finish | Precision class | Straightness | Surface Roughness | R of Edge |
|---|---|---|---|---|
| Grinded | - | 3µm/1000mm | Ra0.025µm | 3µm |
※The above values present the accuracy of lip-land portion.
※These values were measured with the processed samples of 1500 mm die.
※The ultra-mirror finish was obtained with our own polishing machine.
※The grinded finish of Special Class was performed with our own`super-high precision grinder.
Coater Die
Kasen supplies coater die for coating on LCD panel, optical film and roll. Large scale grinding more than 5m is possible. It achieves required surface roughness, straightness and flatness.
| Dimension | ～7000mm(standard grinding) ～2000mm(precise grinding) ～4000mm(extra-precise grinding) |
|---|---|
| Typical accuracy | Straightness 5µm/1500mm（standard grinding） Straightness 1.5µm/1500mm（precise grinding） |
| Application | Coating for film / glass baseboard / etc. |
| Feature | Precise machining for flatness, straightness and surface roughness is required so that even law viscid polymer or solution may be well coated. |
