Atock Co., Ltd.

We also support ultra-thin quartz glass film polishing.

We are a precision parts manufacturer that is expanding its business in Japan and abroad. We deal with consignment high-precision polishing, precision machining, and welding of optical glass mainly for the electronics industry. Materials include quartz glass, semiconductor devices, ceramics, metal material, resin material, carbon material, and magnetic material. We have a track record of supporting ultra-thin film polishing with a thickness of 8 μm (total thickness of 10 to 20 μm after multilayer evaporation) according to customer needs. We have acquired many patents including those in Europe, US, China and Korea. We also sell blades that are used for glass processing.

[Product description] We have realized higher frequencies by using crystal film as thin as 8 μm. This is done by applying our ultra-thin film polishing. We can finish a product with a total thickness of 10 to 20 μm by applying backside polishing after multilayer evaporation. [Market share/Ranking] This is our original technology. No other company has the capability to polish to such thinness.

[Product description] We conduct high-precision quartz glass polishing. We can perform processing with a common difference of ±1 μm in thickness, as long as the maximum diameter is diameter 100 or less.

[Product description] We have a track record in large-diameter polishing and machining. Our products have been adopted for quartz targets, large substrate glass, and observation windows for large equipment.

[Product description] We have a track record in cylindrical machining and grinding. Our products have been adopted as base materials for quartz fiber, light guides, target rods, optic fiber base materials, etc.

[Product description] We can conduct high-precision drilling from a minimum diameter of 0.1 mm. We can handle straight drilling, drilling with a certain angle, and inner circumference polishing of straight holes with a minimum diameter of diameter 3 mm or above. We can perform processing with a minimum outer diameter of diameter 0.4 mm or above and a hole depth of 9 mm. We can process holes with a depth of up to 60 mm in the case of an inner diameter of 1.0 mm. We can process holes with a depth of up to 100 mm in the case of the inner diameter of 2.0 mm. We can also deal with laser drilling starting from diameter 10 μm. Please feel free to contact us.

[Product description] We can manufacture rods with a minimum outer diameter of diameter 0.4 mm or above and a maximum length of 9 mm. We can conduct processing up to 100 mm in length in the case of an outer diameter of 1.3 mm or above.

[Product description] We conduct welding by making use of the characteristics of quartz glass. This is done for semiconductor manufacturing, laboratory instruments for physics and chemistry, and for other applications.
