We sell precision porous chucks that achieve stable adsorption by using porous ceramics. They have high wear resistance and heat resistance, and there is no dust generation from the porous ceramics. Additionally, with a pore diameter of 2μm, they have partial adsorption capability and can uniformly adsorb thin glass and films without deformation. There is no need to replace the chuck for each workpiece size. This product can be manufactured in the required size. Please feel free to contact us. 【Features】 ■ Uses a porous ceramic plate with uniform pores ■ High wear resistance and heat resistance, with no dust generation from the porous ceramics ■ Partial adsorption capability with a pore diameter of 2μm ■ Uniform adsorption of thin glass and films without deformation ■ Partial adsorption is possible / one adsorption plate is sufficient ■ Can be manufactured in the desired size *For more details, please refer to the PDF document or feel free to contact us.

This document introduces the features of "Granite." Granite is made from excellent natural stone known as diorite (commonly referred to as granite) with a uniform texture. It has been naturally dried for thousands of years, resulting in minimal aging changes, outstanding corrosion resistance, and no rust formation. Additionally, we have included information on applications and our commitment to stone types.
