What is a Porous chuck?

A porous chuck is a clamping device used in precision metalworking and machining, primarily utilizing vacuum suction technology to hold workpieces in place. It has a surface with micro-sized holes (pores) that generate suction force, ensuring the stable holding of the workpiece during machining.

The key advantage of this chuck is that it provides uniform suction power, making it suitable for parts of irregular shapes and sizes. Since suction is used to hold the piece, mechanical clamping force is not needed, preventing clamp marks and deformation. Additionally, workpieces can be easily removed after processing, which improves work efficiency.

Porous chucks are particularly useful in:
１．Precision parts machining: Used for parts like those found in electronics or precision molds.
２．Holding complex shapes: Effective for holding irregularly shaped or porous materials.
３．High-speed machining: Can hold pieces firmly during high-speed rotation or cutting.
Moreover, porous chucks allow for pressure adjustment during clamping, enabling the delicate handling of sensitive parts.

Application of Porous chuck

✅ Semiconductor manufacturing
Used to hold silicon wafers in place during polishing or thin-film deposition processes.
✅ Precision machining
Ensures precise positioning of materials like optical components and lenses during processing.
✅ Electronic device production
Applied in cutting or laser processing of thin films or flexible substrates.
