Specialized & General Milling

Wachs Exchanger Mill is a precision machine tool designed for specialized machining of exchanger baffle plates, pass partitions and pass grooves on heat exchangers, as well as general-purpose 3-axis milling. Available in three different travel length models, 4 foot (48 inches), 6 foot (72 inches), and 8 foot (96 inches), it’s designed to interface with Wachs DynaPrep Modular Design Split Frame family. Wachs portable exchanger mill is ideal for surface milling of plates and partitions to the flange plane during an exchanger refurbishing, as well as traditional 3-axis rail linear milling without the MDSF. It features full-length t-style clamping channels on the rail bottom, offering superb clamping flexibility when used for general-purpose milling.

Unlike ordinary mills, it features unique side channels for mounting to Wachs MSDF split frames. This allows the operator to perform flange facing utilizing an MDSF flange facer accessory (FFR or FFC), then mount the exchanger mill to the MDSF. The MDSF then serves as the rotating platform for the exchanger mill, allowing precise positioning of the mill for multiple plate angles. This eliminates the need for indicating and dialing in multiple tools to the surface plane and plate angles.

Wachs Exchange Mill is available in your choice of pneumatic or electric drive. For more information on purchase or rental options, contact your local Wachs representative.
