Tyhjiöhöyläys

Tyhjiöhöyläys, also known as vacuum planing, is a manufacturing process used to create extremely flat and smooth surfaces, particularly on materials like glass and silicon wafers. The core principle involves using a vacuum to hold the workpiece in place while a cutting tool shaves off microscopic layers of material. This allows for precise control over the surface topography, achieving levels of flatness and smoothness that are difficult or impossible to attain with conventional machining methods.

The process typically begins with a workpiece secured to a vacuum chuck. A precisely controlled cutting tool, often a diamond or ceramic bit, is then brought into contact with the surface. The vacuum not only holds the workpiece but can also assist in removing the fine debris generated during the planing process. The depth of cut is meticulously controlled, often down to the nanometer scale, enabling the removal of surface imperfections and the creation of a highly uniform finish.

Tyhjiöhöyläys is a critical technique in industries where surface quality is paramount. It is widely employed in the production of semiconductor wafers, where even slight variations in flatness can impact the performance of integrated circuits. Similarly, in the optics industry, tyhjiöhöyläys is used to prepare surfaces for lenses, mirrors, and other optical components, ensuring minimal distortion and maximum efficiency. The precision and control offered by this method make it indispensable for applications demanding the highest standards of surface flatness and smoothness.
