Features
- Mechanical Features 1 

> Excellent thermal balance and rigid cast construction to ensure the best machining accuracy and durability. U-V axes, with linear guide way for accurate taper cutting.

> Using direct drive AC servo motors, high precision ball screws on linear guide ways with optional. 0.05mm resolution glass scale, assures precise positioning and fast response to cutting conditions.



 - Mechanical Features 2         

> Stainless steel 3-sided worktable and brushed stainless work tank for long endurance and least maintenance.

> U-V axes with up to ±50mm travel for wide taper angles (±21 degree).

> (Reach Condition:100mm Z-axis height and DA+DB=15mm at least; a set of wide-angle diamond guides and nozzles are required.)



 - Laser Alignment               

> Laser measurement of X,Y and U,V axes. Highest quality super precision linear guide ways, 32mm or 40mm diameter X,Y precision ball screws (depending on model) assures precise positioning, accuracy and long endurance.



  - Ball Bar Test                               

> Renishaw ball bar testing used to test and record each machine's X, Y simultaneous movements. This guarantees ideal table squareness and ball screw back lash. (option)



 - Machanical Features 5           

> Each EDM undergoes over eight hours of continuous machining to verify correct electronic functions and mechanical accuracy.

> And it must pass the sample test cut by 1st Cut, 2nd Cut and 3rd Cut that also measured by Mitsutoyo micro-meter and surface tester.

> For sure both accuracy and surface roughness are qualified to meet the standard.



Controls
- CNC Controller                   

> All Software and Hardware are with full authorized. (Copyright Reserved by CHMER)

> Adopted IPC 586 Mother Board.

> Adopted Compatible 5x86 grade Processor (CPU).

> 64 M Bytes DRAM.

> High capacity storage device CF Card 128 M Bytes.

> Touch Screen and Optical Mouse Support(OPT).

> Synchronized 6th Axis (B axis) Support (OPT).

> External USB Card Reader and lntranet Data Exchange Support (OPT)

> Using CHMER's exclusive CNC controller and proprietary software; CHMER provide the latest software version and updates to optimize the machine functions and Cutting technology.

> All software tunctions built-in and controller are fully compatible with FANUC post processor in CAM software.



 - Cutting Edge Remote Monitoring Function             

> Real time monitoring of machine operation without attending to the work-shop! You see what the operator sees on the CNC controller from anywhere on your home PC or laptop. It definitely gives you more freedom!

> Quick, spontaneous technical assistance or trouble=shoot through

> Remote Monitoring plus telephone conversation with your technical people reduce down time and increase your productivity!

> Easy set up! Just install the software on your computer and get immediate access via existing network.

> Programming N.C file with your CAD/CAM system and up-load it to the CNC controller.


                 

 - Multi-Functional Corner Aided System     

> Corner aided system utilizes special technology to obtain clean inferior / exterior angle for stamping mould.

> About sample in the picture:

> Work condition: Wire Diameter= 0.20mm

> Work-piece material= SKD-11

> Cut No.= 1 cut

> Measured test result=150X scales bye profession optical projector.

> Follow the detail corner setting of users. IPC will compute the optimize power.

> Output and change the servo gain to drive the feed speed be precisely.

> Eliminate the corner burst through software path calculation about the curve distortion.

> To bring the perfect corner comes out.
