Mactech models available for rent or purchase:
LC Clamshell Lathe
The LC low clearance series are designed to fit into tight working areas, as well as minimize machine weight.
These clamshells are lightweight, but retain rigidity during operation.
USS Clamshell Lathe
The USS series combines the low clearance of the LC clamshell lathes, while providing additional thickness and strength.
Larger diameter clamshells must be rigid to maintain a consistent and accurate machining process.
The USS clamshell lathes offer heavy-duty construction for even greater rigidity during operation.
WD Clamshell Lathe
The WD series worm drive system provides the necessary power to cut extra heavy wall, and is capable of cutting pipe greater than 40 inches diameter. Mactech’s large diameter clamshells lathes are exceptional OD mount facing tools for heat exchanger resurfacing.
