It is possible to clamp castings with irregular surface holes that are open for work. There are types that can be tightened from the top and bottom, and they can also be used for stop holes.
Halder's bore clamps can accommodate various workpieces. There are types that do not damage the inner surface of the hole and types that may leave marks on the inner surface but can clamp securely. When the screw is tightened, the ball or segment expands while maintaining concentricity, clamping the hole from the inside. The type that pulls downward can also be automated using pneumatic cylinders and other devices. For more details, please contact us or refer to the catalog (P.421~).
