Polaris Chuck

Polaris Chuck

It is suitable for transporting wafers with warping or those that leak with a suction chuck.

It is suitable for transporting wafers with warping, as well as wafers that leak with suction chucks and thin wafers. The chuck body is made of high-purity alumina ceramics, and only the workpiece suction surface uses porous ceramics. With an average pore diameter of 20μm, it can distribute the suction pressure concentrated in the grooves, which are typically about 1.5mm deep in conventional suction surfaces, thereby minimizing deformation of thin workpieces during suction. Mesh particle sizes can be selected from grades #100, #220, and #400. A conductive Teflon coating treatment can also be applied to the workpiece suction surface.

Introduction of the porous product lineup *Available for short delivery times!

Introduction of the porous product lineup *Available for short delivery times!

Introducing porous products such as glass film suction plates, precision floating tables, and precision porous chucks!

This is an introduction to the "porous products" handled by P.D.W. Starting with the "precision floating table," which can process and transport glass substrates and films with high precision and non-contact, we also offer products such as the "circular precision porous chuck," which maintains suction fixation without shifting the workpiece even during cutting operations. Our company challenges the limits of precision with high-quality natural stone, responding to precision requirements of 1/1000 millimeter units. 【Product Lineup】 ■ Precision Floating Table ■ Precision Chuck Table ■ Precision Porous Chuck ■ Glass Substrate Suction Plate ■ Circular Precision Porous Chuck 【Our Features】 - We always keep stock of stones in the 5000×3000 class, enabling us to respond to short delivery times through integrated production from cutting to product completion. - We guarantee flatness, parallelism, and perpendicularity precision values that meet customer needs. - We provide modifications, repairs, and maintenance for stone products. *For more details, please refer to the PDF materials or feel free to contact us.

Precision porous chuck *Partial adsorption (fixing) is possible

Precision porous chuck *Partial adsorption (fixing) is possible

No need to replace the chuck to fit the work size! Adopts a porous ceramic plate with uniform pores. Proven performance of 2000 × 1000 as well.

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.

Precision Granite Technology "Porous Chuck RB31"

Precision Granite Technology "Porous Chuck RB31"

Significant improvement in work efficiency! A porous chuck that allows for easy and reliable vacuum suction fixation.

The "RB31" is a porous chuck that securely holds the workpiece using a vacuum suction method created by negative pressure through a porous material. Not only can it easily and reliably fix extremely small, thin, and long workpieces, but it also accommodates non-magnetic materials, making it highly effective for grinding various materials. Customization of size and shape according to the workpiece is possible, as well as connecting multiple units. The ease of attaching and detaching the workpiece, as well as adjustments, significantly improves work efficiency. 【Features】 ■ Customizable ■ Easy to clear clogging ■ Grinding of the suction surface itself is possible ■ Compatible with various workpieces ■ No deformation due to processing heat For more details, please refer to the catalog or feel free to contact us.
