All-in-one Servo Closed-Loop Wire-Cutting EDM Machines (WEDM-MS)(LTW40T)

LITONG precision MS-WEDMs are a high-end MS-WEDM, with excellent cost performance. It can completely replace the traditional HS-WEDM & partially replace the LS-WEDM. LITONG MS-WEDMs are suitable for all kinds of Black metal, Copper & Copper Alloy, Aluminum & Alloy, Tungsten steel, Titanium alloy, Die steel etc. other materials of precision parts and tool processing.


Litong LTW40T adopts Japan Panasonic all-digital AC servo unit and motor closed-loop control, and adopts imported precision ball screw, linear guides, and bearing to ensure the geometric accuracy and positioning accuracy of the machine tool , fast moving speed and stable operation.
