The high quality MEEHANITE cast iron

ensuring long-lasting accuracy and stability. Each Alphaturn cast iron frame has been tested in the production of authorized Meehanite foundries.

Level bed with two guide planes

The alpha-turn cast iron bed has a 2-step guidance system in order to guarantee constant stability, especially in heavy-duty machining. The occurring forces, during machining will be better distributed on dual rails. For the user this means larger infeed, faster in two levels working feeds and a perfect image rotation in conjunction with the powerful main spindle.
