Servo Control Wire-cutting EDM Machines (WEDM-MS)(LTW63A HA)

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.

Description

LITONG precision Wire EDM machines all use world-famous brand spare parts: Panasonic servo motors, Schneider Electric Relay, contractor, Power circuit Breaker, etc.

Features

Main features of Servo Control Wire-cutting EDM Machines:


1.Medium and large machine tools, processing travel to reach: Y/X/H:630/800/400mm.


2.Dual circuit intelligent sampling, so that the processing of forewarning information for data acquisition, sent to the computer analysis and processing, so that after sampling for stable discharge, accurate processing of material fault information, so that the surface quality of processing Ra and processing accuracy to achieve the ideal state, the processed product consistency and good.


3.High-grade guide rail imported from Taiwan and double nut lead screw

 pair are adopted. Z-axis adopts Taiwan double linear guide rail, with T-type high strength body structure design, which more effectively ensures the finish and precision of the workpiece and the service life of the machine.


4.Adopts a new type of mechanical two-way intelligent constant tension mechanism, which can adjust the tension according to the processing requirements and the diameter of molybdenum wire, overcomes the insensitivity of the simple hammer tension mechanism to the tension fluctuation of electrode wire, and effectively ensures the verticality of the workpiece and eliminates the surface stripes.


5.The whole machine adopts environmental protection device, new waterproof splash design, effectively reduce the splash of working fluid during processing, protect the environment and ensure the use of safety, so that the overall equipment is more beautiful, more environmental protection.


6.Using the newly developed AR non-electrolytic discharge digital pulse power supply, the efficiency and smoothness are greatly improved.


7.The water treatment system adopts the self-priming pump water treatment system combined with high-precision filter element and environmental protection water agent working fluid, which makes the jet flow more uniform and the working fluid service life longer, greatly improves the cutting quality and reduces the processing cost.
