A vertical rotary table surface grinder typically features a vertically positioned grinding spindle and a worktable that is either adjustable or fixed. This type of grinder features a circular magnetic chuck worktable that rotates continuously. The workpiece is placed on the table and passes beneath the grinding wheel as the table rotates for grinding. Unlike horizontal rotary table surface grinders, which are primarily used for machining large components, vertical rotary table surface grinders are primarily suited for machining precision parts.
Vertical rotary table surface grinders are primarily used in the semiconductor and optical industries for grinding a variety of high-hardness, high-precision materials. Key applications include:
1.Semiconductor substrates and devices:Primarily used for processing silicon wafers, silicon carbide, aluminum nitride, alumina ceramics, iron-cobalt alloys, gallium arsenide, and wafer thinning machines.
