Danobat Coupling Solutions



Marathon offers a wide range of CNC turning centers for machining Premium and API couplings and connectors. Our heavy duty Danobat lathes are equipped with preloaded ball screws and precision, rugged spindles to successfully machine premium and super premium couplings. We offer machines both for medium and for high volume production. For high volume production we offer a SMW-Autoblok indexing chucks, specifically designed for couplings and featuring high volume coolant thru chuck system to evacuate chips fast. As an option, we can offer in-process laser thread gauging to further increase quality and production rate.

CL Series (7,9,13,16 – Manual Loading)

Designed specifically for the couplings machining, the CL lathes are the most appropriate solution for those companies which are looking for the best solution for manual coupling handling.


CIH Series (7,9,13,16 – Indexing Chuck)

The CIH model is a horizontal lathe with a single spindle and a 45º slant bed with box ways. This model is designed to work with an indexing chuck and automatic loading and unloading system. As the chuck indexes 180º the CIH does the threading on both sides of the coupling in a single chucking. The heavy duty hydraulic drum type turret with four positions at 90º is equipped to work with high pressure (725 psi) coolant thru the tools.
