The expectations in today’s manufacturing environment are high. From cutting forces to precision and safety, perfection is demanded. What was looked at years ago as too extreme and not possible has changed over the years to become standard.

Machine and cutting tool technology has advanced in quantum leaps. Therefore, the expectations of clamping devices has risen dramatically.

Especially in the expanding mandrel area, a difficult task is rigidity and safety, due to the limited dimensions. But solutions to these problems are the highest priority for high material removal rates. And this is exactly where Hainbuch’s expanding mandrel’s qualities lie, and lead to incredible production output.

Excellent for the demanding user!

Mandrel Bushings

The principle of the clamping bush moving to the back, the so-called pull back effect, can provide substantial stability to the work piece. Even gripping on short lengths and large diameters can be effective. Please let our engineers solve your problems.

Special Bushings

These are some of our solutions. We can clamp any symmetrical part that can be EDM'd.
