Machine features
1)High quality cast
iron machine base, column and slide. Integrated frame column structure
featuring optimum thermal symmetry and stability.
2)T-shape integrated
machine base structure borrowed from Jig borer which ensure the machine
accuracy. The worktable move toward the static spindle which ensured maximum
spindle rigidity.
3)Full closed
enclosure with twin-layer spray proof makes the machine more pleasant in
outlook and environment protection Special protection door and MPG design
featuring human-machine harmony.
4)Pre-tensioned ball screw pair with 60o
rigid bearings to ensure the machine’s transmission accuracy and rigidity
5)Rotary accuracy of
spindle group is ensured by precision machining and assembly. Grease lubrication
on spindle bearing. Outer cycle forced cooling is adopted to the spindle to
reduce the heat distortion and improve the working accuracy stability.
6)HEIDENHAIN encoder
featured closed-loop detection for both A-axis and B-axis to ensure the
indexing accuracy.
7)Cam type mechanic interchange arm with twin toggles. Tool change and
the door open/close is realized simultaneously. Standard BT50 tool. Servo
driven tool magazine featuring high efficiency, accuracy and reliability
8) SINUMERIK 840D control system for X、Y、Z、A、B axes control. Built-in Ethernet andRs 232C interface. High quality key electric elements to ensure machine reliability.
