home; silicon metal grinding machine; silicon metal grinding machine. Silicon Carbide Wafer Grinding. The EVG-250/300 series Vertical Grinding Machine combined with Engis MAD Grinding Wheels can achieve a superior surface finish on silicon carbide wafers to reduce or even eliminate loose abrasive lapping steps.

Our vertical spindle rotary table surface grinders are favoured by clients over competing brands for applications in grinding semiconductor materials such as quartz, ceramic, silicon and SiC. Unlike metal surfaces, which can be ground by stone, these semiconductor materials require diamond-coated wheels for grinding.

When you depend on complex machinery for the livelihood of your business, preventive care is a must. Just as with any piece of equipment, precision grinding machines will last longer and stretch your investment further if you take care of routine maintenance.

SILICON MACHINING Silicon can come as Monocrystalline silicon (or single crystal silicon) and Polycrystalline silicon (polysilicon or poly-si). Silicon is often used as the primary base material that silicone microchips and semiconductors are made from; which can be found in virtually all electronics.
