Mechanical Structure - Key points
High Precision

• Smart Corner Control, Stable Discharge processing, Super Finish Circuit (SFC) provide more accuracy.

Efficiency

• DPM module, Precision mark control, Electrolysis Free (EF) generator system.

Cost effective

• Intelligent access control, Reduce Wire Consumption, Economic concerned price.

Intelligent Networking

• Remote monitor management, Controller connector, Portable device monitor.

Automation

• High speed Auto Wire Threading, Robo-arm transfer of Workpiece, Probe Auto Measurement and Correction.

Machine features

• Rigid U, V truss design
• Stainless steel worktable with hardness HRC 50°
• Machine casting designed based on FEA analysis to increase rigidity
• Machine base with extra wide design

Linear Shaft Motor Driver System
The machine provides constant temperature control to improve machining accuracy by reducing heat from the linear motor. Water circulation reduces temperature generated by the linear motor; high thrust, high efficiency and low energy consumption. Features include a 0.1 μm high-resolution digital ruler and controller for high-precision forming and ultra-fine finishing.

Improved Operability

• Class-leading ergonomic HMI panel, easy to operate
• Workpiece positioning function, maintenance and diagnosis information, technology data search function, graphical interface and useful functions

4-side Hardened Stainless Steel Table

• TUV certified for safety and metal design
• Power slider door design to save installation space and enable light operation

Auto Wire Threading

• 200 mm submerged threading capability; 400 mm thickness threading at break point
• High speed auto wire threading system: wire annealing and cutting ~10 sec; threading ~10 sec
• Reliable AWT design enabling continuous unmanned 24-hour operation; can thread from wire break point; water jet function enables threading of workpieces up to 500 mm

On-line measurement & Multiple workpiece machining

• On-line measurement and calibration before machining to reduce calibration time; automatic measurement calibrates reference point
• Direct on-line measurement after machining to avoid errors from dismount/mount
• Automatic compensation of 3D flatness and parallelism (AR), automatic reference point measurement, automatic progression to next workpiece
