The Sterling drill grinding machine will sharpen drills from 18 inch through 2-12 inches in diameter. The Sterling drill grinder uses a V-block method of holding the drill Figure 2. The V-block is simple, positive, and eliminates the need for collets and chucks.
Furthermore, surface grinding machines can be sub-divided into three main types of construction 1 the column, 2 moving column, and 3 transverse construction. An example of the column type grinder is shown in Figure 4.73. The design depicts a few characteristics for ceramic machining and provides a high-quality machined surface.
Swing frame grinders. The maximum angular exposure of the grinding wheel periphery and sides for safety guards used on machines known as swing frame grinding machines shall not exceed 180 deg., and the top half of the wheel shall be enclosed at all times.
