    • Exactly simultaneous tooling at main spindle side and back spindle side
      • With separate back tool post, and back spindle cross traveling (X2, Z2) , tooling at back spindle side(S2) can be performed at the same time while tooling at main spindle side is under way, without need to wait with each other, reducing cycle time greatly.
    • 21-tool capacity
      • Five tools for OD, four tools for cross drilling milling, four tools for face ID working and eight tools for back ID working make it possible for completed a wide variety of tooling jobs at one-time.
    • Built-in main and back spindle motors increasing tooling accuracy.
      • Increased accuracy of speed and phase angle while both spindle synchronize.
    • With synchronization function of Z1 and Z2 axes, possible to do R cut-off, etc.
    • Direct motor-drive rotary guide bushing, available for high-speed and accurate machining.
      • Max. speed : 10,000 min-1 Max. machining length : 170 mm Geometry accuracy, dimension accuracy and surface roughness are much improved, with less noise even at high speed.
      • “ Not suitable for water-soluble cutting coolant.
    • Guide bushing type or guide bushing-less type is selectable according to length of the parts to be produced.
      • Guide bushing-less type does not require ground bar stocks, suitable for cold drawn bar machining also, reducing the remaining bar length.
    • 4-spindle cross tool attachment can be mounted, available for Y-axis complex tooling, such as cross drilling, tapping, up-down milling, etc.
    • Single or double-headed drill collet holder can be mounted at №20- through bore ID tool post, available for face, back ID working.
    • High rigid cast machine bed, absorbing the vibration caused by high speed rotation and rapid traverse.
    • Higher precision
      • Rigidity of both the tool posts at main spindle side and the feed axis slide guide are upped, so tooling accuracy is not influenced by cutting load variation.
      • Based on thermal physics, main / back headstocks, and X axes (X1, X2) are all installed horizontally, reducing the heat-induced deformation to minimum.
    • Reduced tooling idle time
      • Rapid traverse : Max. 32 m / min (X: 24 m / min)
      • Tool span is only 28 mm, greatly reducing tool change time.
      • Maximum high- speed control, reducing idle time.
      • Double control system, programs can be specified at main and back spindle side separately, and they are read and processed at the same time.
      • With X2 axis and independent back tool post, simultaneous tooling at main and back spindle side can be done.
      • High-speed cycle tooling
      • M and T codes, axis feed can be specified at the same single block.
      • Direct C-axis indexing.
      • If with C-axis (option), when spindle indexing is done, it stops at indexed position directly, without need to return to reference point, reducing spindle indexing time.
      • MHigh-speed thread cutting function, reducing thread cutting time.
      • Large chips pan, good for long-time unattended operation. Also, possible for taking out the products and removing the chips during machine operation.
    • Friendly, easy operation
      • Operation panel is closer to cutting zone, which also can be rotated, convenient for seeing the program on monitor and tool movement, etc.
      • Lift-to-full open safety door for cutting zone room, convenient for tool setup.
      • Easy-to-rake out chips discharge port design.
      • Chips pan is put on coolant circulation inlet, convenient for cleaning.
      • GE FONG-made software is provided as standard accessory for easier operation such as automatic programming, tool-tip height compensation, tool life management, periodic maintenance screen, and automatic cut-off, automatic facing, tool interference check, options (as work conveyor, etc.) ON/OFF setting, etc.
      • Mirror image function is convenient for programming for machines with opposed tool slides as GO-205-II. Also,¨mirror image ON〃(G68) is built in the GE FONG-made opposed tool calling software, so without need to specify G68 or G69 with the tool called, preventing tool crash due to programming miss.
