HIGH PERFORMANCE WIRE CUT EDM
HIGH PERFORMANCE WIRE CUT EDM - AWT 5S
AWT 5S

1.
Each axis uses precise ballscrew and linear motion guide.
2.
AC servo motor directly go through coupling to drive the ballscrews.
3.
The work table is manufactured from stainless design to ensure best maintence.
4.
The U, V axes located upper from the columm to offer accurate stability, it can reach precise taper machining when facing high wire tension and high water pressure.
5.
High rigiding design, and well thermal balance are used for precision machining.
6.
Submerged work tank you don't find more spread water, offers a complicated machining shape request and stable cutting status.
7.
To put the work piece into submerged water, keeps same temperature and reach the work piece stability and non-transformed shape.
8.
Simple and reliable Automatic Threading Device design, applies high precision accuracy and easy operator maintenance.
9.
Specially designed Ø 1.0mm high pressure water jet on the Automatic Wire Threading system, offers enhanced reliability for threading brass wire from Ø 0.1mm~Ø 0.3mm.
10.
The Automatic Wire Threading cut design ensures a clean-cut burr free sharp point to the new wire.
11.
Time saving submerged Auto Wire Threading facility.
12.
Heavy-duty wire spool shaft design for ease of maintenance.
13.

New generation control system WINDOWS based design Equipped with unique RTX Clock software User friendly, CNC control interface, for easy operation 15" touch-screen monitor and mouse, smoother programming for users, Optional 4 axes on-board conversational programming system.

Intelligent OV Circuit
Specially designed intellent ignition control circuit permits ignition voltage, voltage adjustment and control by computer, and is excellent for machining various work piece materials, with both thick and thin sheet plates, Also a voltage stabilizing circuit maintains discharge machining at constantly high speeds and 20%, especially when working on particularly thick or think work piece.

Super Fine Loop
The super fine loop employs a high frequency, non-electrolytic machining method. The process combines stability wire feeding tension control.All of which fabricates an extremely fine work piece surface.

 
Allows the operator/company to remotely monitor the machine either at work or via the internet.
