From short to long roll and shaft, we will mirror polish all surfaces. We operate single piece production as well as mass-production. Please contact us for details.

<<Precision>>
Periphery roughness: Ra1.5nm、Rz10nm(SUS304, glass, etc)
We deal with Ra0.010μm or less roughness for aluminum as well.

<<Materials>>
Stainless, Titanium, Aluminum, Glass.

We also can handle coated products.
(Nickel coat, chrome coat, hard rom coat, etc.)

Our processing will guarantee to produce nano level roughness while maintaining measure precision and roundness.
We not only can lap process on different types of materials, but also can lap on coated surface or used as preparation for coating.

Oddly enough, most customers do not know that lapping can be used as pre-coating and do receive questions regards to it.

<Example1: Alumina thermal sprayed surface>
To improve precision and life of currently used surface plate, we applied alumina thermal spray which eventually led to improved flatness and surface hardness. (Recommended for those customers who are currently using cast iron surface plates.)

<Example2: Ni plated surface/NiP plated surface>
Applied lapping to Ni and NiP plated surface which then used as adsorption face, reflecting face and pattern treatment face.
(Cheap Ni and NiP platting is commonly used to gain antirust effect.)

<Example3: DLC, TiN treatment>
For those surfaces, such as adsorption face, require high specularity and harden surfaces, we applied DLC or TiN treatment to harden the surface.

<Example4: hard anodized aluminum>
We applied hard anodized aluminum onto aluminum base and then lapped anodized aluminum layer. Improved flatness and hardness. It is commonly used for adsorption face.
