4. System operating box

²The system operating box adopts suspension type, allowing users to move left and right. The system features a handheld electronic handwheel for easy operation and a safety interlock to ensure safety and reliability.

5. CNC system

²The CNC control system adopts Japan FANUC Oi MF1 plus Systemabsolute value operation CNC system.The systemwith high-speed and high-precision function and supports 5 axis position and 4 axis continuousfunction. Each axis adopts Japan Fanuc αseriesabsolute value encoder and motor, which ensures the control system has the advantages of high stability, fast speed, smooth surface and high precision, and has the functions and machining capabilities due to mold manufacturing.

²Electric control auxiliary device:Fully enclosed constant temperature electric cabinet, standard protection, sealed dust, electric box equipped with lighting. (Circuit, oil circuit and machine tool soft connection)

6. Automatic 90 degree angle milling head ²

²Equipped with automatic grabbing head and automatic door opening head library, it can automatically grab, automatically divide and realize automatic five sided processing.

7. X/Y/Z axis liner scale

²Weaken the influence of machine temperature change on machining accuracy and improve accuracy stability.
