BNC-3000/3500/4000 Series

The headstock is rigid and well balanced for high speed running & huge loading capacity. An automatic speed changing system isprovided by powerful gear box, hence no noise would be created in the headstock. Standard spindle bore is 106mm, and it is available with 153mm, 254mm, or 356mm on your request.

2 steps gear box performs high torque spindle power. The smooth & fast speed changing time is to ensure fast working condition.

A travel chuck guard is designed to take biggest chuck and it is equipped with safety device (interlock). A very friendly design to ensure you using the machine easily and safely.

The rigid rib designed carriage is coated with low friction pad & lubrication way for smooth & rigid moving.

An extra long quill to ensure that you get full cutting length, even when the machine is equipped with power turret. The complete tailstock can be moved by engaging to the carriage manually. A revolving quill is available if request

With one-piece casting bed made of Meehanite licensed casting (option), machine is capable for heavy-duty turning. Large working capacity (Swing in gap 1020~1280mm, Swing over bed 760~1020mm, Swing over cross slide 420~680mm, and Turning length 1M~6M) with wide selection of spindle bores including the largest bore of 356mm for a wide application of various industries. Large bore is particularly suitable for oil & gas industry.

BNC-30120 BNC-30160 with one-piece base (opt.) (for reference only)

The double "box ways" designed bed for rapid traverse and the extremely wide bed ways will are able to takeheavier work pieces. The bed is designed for easier chip flow into chiptray or chip conveyor (on request).The large diameter ball screws arepreloaded to ensure perfect positioning & repeatability.

An extra deep tray will make sure a big volumn taken, and both chip trays and coolant tanks are separately made. Those are supported by rail, and easy to remove the chips. An additional chip conveyor with high pressure washdown system is available if request.

The high pressure pump ensures ample coolant no matter which type of tool holder is used

The automatic lubrication pump is installed at low level for easy monitoring.

High-tech electrical cabinet meets the latest CE regulation.

The efficient pneumatic fitting system offers ease in maintenance.
