E.H. Wachs all new DynaPrep® MDSF split frame redefines the category of cold cutting machine tools for pipe and vessels

Heavy duty form tooling and pipe weld preparation


E.H. Wachs introduces the next major advance in pipe cutting and beveling split frame machine tools, the DynaPrep Modular Design Split Frame, or MDSF. Wachs DynaPrep® MDSF is designed for cutting, beveling, facing, counterboring and flange facing pipes and vessels for popular nominal pipe sizes ranging from 2” to 60” O.D. (DN50-1500). Highly portable, it’s strong and powerful enough to form tool up to 2.5 inch (63.5 mm) heavy wall pipe without reverting to cumbersome all steel construction.

Engineered to be powerful, strong and lightweight, DynaPrep offers unmatched form tooling capability on heavy wall pipe including high alloy material. Sold as complete kits or individual components the DynaPrep MDSF is available in your choice of pneumatic, hydraulic or electric drive.

Clients’ needs in cold cutting machine tools continue to change and evolve. As the innovator and market leader in split frame technology, E.H. Wachs continually evolves its products to meet the needs of their clients. Needs such as split frames that were easier to set up, easier to operate, and more powerful to handle heavy wall form tooling. At the same time Wachs didn’t change what makes the previous model, the LCSF Low Clearance Split Frames great: their low clearance design that fits into tight spaces, its lightweight construction, and its wide range of versatile accessories.
Designed to meet and exceed all these parameters, Wachs has developed the all new DynaPrep MDSF Split Frame series. Engineered to surpass anything available today it was benchmarked against the rest and built to be the best.

The core design principal during its development was power combined with durability. Like every Wachs split frame, the DynaPrep MDSF is the basis of a complete machining system that will be used worldwide for simple cutting and beveling tasks to complex tasks, including trepanning, casing cutting, deep counterboring, large diameter flange facing, and SGR replacement projects.

E.H. Wachs DynaPrep MDSF is a complete redesign of the tried and true clamshell-style split frame, featuring dozens of innovations and patent pending features designed to make it more versatile, more powerful and faster to setup and operate. The DynaPrep is built to withstand the higher torque and horsepower required for greater performance, particularly when form tooling. V-Lock joining technology, quick mount tool slides with Micro Adjust, Rapid Advance and Retract plus two tool setup are just a few of the breakthroughs that allow the MDSF to redefine the standard for pipe cutting and beveling machine tools.

E.H. Wachs is the industry leader in cold cutting weld prep machine tools designed to eliminate the health and safety risks associated with hot torch cutting and grinding. Compatible with the industry trend of removing workers from combustible hydrocarbons, radioactive hot zones, and inhalation dangers, the DynaPrep MDSF has been designed from the ground up to be adaptable for use in these hazardous environments.

E.H. Wachs products are available from different sales locations all over Europe, USA, Canada, Asia, Africa and Middle East.

E.H. Wachs in Lincolnshire, USA and Orbitalum Tools GmbH in Singen, Germany are brands of the "ITW Orbital Cutting & Welding" division which stands for the best, most efficient technology for all aspects of orbital cutting and welding around the globe.
