Specification of Alumina Vacuum Chuck Porous Ceramic Plate

This alumina vacuum chuck plate provides strong, reliable holding for precision work. The porous ceramic material allows excellent vacuum flow across the whole surface. It holds parts securely without shifting during machining or inspection.

The plate is made from high-purity alumina ceramic. This material is very hard and resists wear extremely well. It handles high heat easily, working fine up to 1500°C. This makes it suitable for demanding processes like semiconductor manufacturing. The ceramic also resists chemical attack from coolants and solvents.

Porosity is tightly controlled. The plate has many tiny, interconnected pores. These pores let vacuum pressure pull parts down evenly. The specific porosity level is chosen for the best suction without leaking too much air. This ensures consistent holding power. You get uniform vacuum distribution across the entire chuck face.

Flatness is critical. The plate surface is ground to a very precise level. Typical flatness tolerance is within 0.001 inches per foot. This prevents part distortion when held under vacuum. The surface finish is also very smooth. This minimizes any marks on delicate workpiece surfaces. It also helps create a good seal.

Standard sizes are available. Common diameters range from 100mm to 300mm. Thickness usually falls between 6mm and 12mm. Custom sizes and shapes can be made too. The plate features standard vacuum port connections. These are designed for easy hookup to your vacuum system. Mounting holes are included for simple installation onto machine tables or fixtures. The alumina ceramic is electrically insulating. This is important for applications involving sensitive electronics.

Applications of Alumina Vacuum Chuck Porous Ceramic Plate

Alumina vacuum chuck porous ceramic plates hold workpieces securely using vacuum suction. This is essential in precision manufacturing where parts must stay fixed. The porous ceramic material allows air to pass through its tiny holes. A vacuum source pulls air down through these holes. This creates suction holding the part firmly on the flat surface. The plate itself is very flat and rigid. This prevents any bending or warping during work. Alumina ceramic is extremely hard and resistant to wear. It handles high temperatures easily. This makes it perfect for demanding processes.

These plates are vital in the semiconductor industry. Workers use them to hold silicon wafers during etching, grinding, or inspection. The ceramic surface is non-marring. It protects delicate wafers from scratches. The material is chemically inert. It resists acids and solvents used in chip making. This ensures long life and reliability in cleanrooms.

Laser cutting and engraving operations depend on these chucks. They hold materials like metal sheets, plastics, or composites steady under the laser beam. The alumina ceramic withstands intense laser heat and sparks. It won’t melt or degrade like plastic fixtures. This prevents damage and maintains accuracy. Workers get consistent results.

Printed circuit board (PCB) assembly uses these plates extensively. They hold small, delicate components during soldering or placement. The vacuum grip prevents tiny parts from shifting or blowing away. The flat surface ensures components sit correctly. The ceramic’s electrical insulation is crucial. It prevents short circuits during electronic testing.

Medical device manufacturing also relies on alumina vacuum chucks. They hold small, complex parts for machining or assembly. The ceramic material is biocompatible and easy to sterilize. This meets strict medical cleanliness standards. The porous structure provides uniform suction. This holds irregularly shaped implants or tools securely without damage.

5 FAQs of Alumina Vacuum Chuck Porous Ceramic Plate

What is an alumina vacuum chuck?
This is a flat ceramic plate. It holds workpieces using suction. Tiny holes cover the surface. Air gets pulled through these holes. This creates the vacuum. The plate is made from alumina ceramic. That material is very hard and resists chemicals well. It works for holding delicate or oddly shaped items securely during machining or inspection.

How hot can these chucks get?
Alumina ceramic handles high heat well. You can use these chucks up to about 1500 degrees Celsius. That’s much hotter than most metals. The heat doesn’t hurt the chuck itself. It keeps working fine. This makes it good for processes needing high temperatures.

How do I clean it?
Cleaning is simple. Wipe the surface with a soft cloth. Use isopropyl alcohol or a mild detergent. Avoid harsh chemicals. They might damage the ceramic surface. Don’t use abrasive pads. They can scratch the plate. Keep the holes clear of debris. Blocked holes weaken the vacuum grip.

How long does it last?
These chucks last a long time with proper care. Alumina ceramic is very tough. It resists wear and scratches. It doesn’t rust or corrode. Avoid hard impacts. Dropping it can cause cracks. Handle it carefully. Regular cleaning helps it work well for years.

Why isn’t the suction strong?
Check a few things first. Make sure the vacuum pump works correctly. Check all hoses and connections for leaks. Look at the chuck surface. Are the holes clogged? Clean them thoroughly. Check the workpiece. Is it flat enough? Does it cover enough holes? A rough or uneven surface prevents a good seal. The chuck itself might be cracked. Inspect it carefully for damage.
