Wachs MDSF DynaPrep Split Frame Cutting Machines

Wachs DynaPrep MDSF split frames redefine the category of cold cutting machine tools for pipe and vessels. Rugged yet highly portable, The DynaPrep MDSF offers unmatched form tooling capability on heavy wall pipe, including difficult to machine high alloy materials. Designed for cutting, beveling, facing, counterboring and flange facing, it’s available in sixteen standard models for nominal pipe sizes ranging from 2in – 60in O.D. (DN50-1500), with each model covering a generous 6in range. Sold as complete kits or individual components, the DynaPrep MDSF is available in your choice of pneumatic, hydraulic or electric drive.

Split frames are named for their ability to split in half at the frame, or “break open” and bolt back together again. This allows them to open and mount around the O.D. of inline piping, or they can be slipped closed over open ended pipe. The LCSF has been engineered to apply precise, consistently square cuts and bevels on pipe, tube and casing the first time, every time.
