This machine adopts bed-type cross slippery platform structure and has a good structural configuration. It has enough strength, rigidity and stability, both the manufacturability and maintenance are good. Through repeated experiment, this machine is proved to have good dynamic property, high precise motion accuracy control, stable machining precision and good stability. It can automatically finish the milling, boring, drilling, tapping, reaming, and other machining processes without changing the clamping method. It’s easy to operate and maintain, extremely suits for batch processing of components and parts. It’s an ideal equipment for automobile and motorcycle parts, military, valve, textile, print, package, mold and other mechanical manufacturing industry, it’s also suitable for vocational education and training.
A. high rigidity and long precision retaining ability
The bed, saddle, table, vertical column, spindle box and other major parts are all molded by resin sand, using super high strength and high quality cast iron, with box or honeycomb structure and enough stiffener board, also through aging treatment to make sure the machine has high rigidity and long-term, stable accuracy.
On X and Y axis, we use precision roller type linear guideway produced by HIMWIN or PMI. The compact structure, smooth motion and high accuracy combine to create an impeccable highly rigid and highly stable mechanical guidance system.
The high-performance spindle is imported from Taiwan. We use the lubricating grease to make sure the spindle bearing has a constant and reliable lubrication. It performs excellently, not only environmental friendly but also maintenance-free.
For the three-dimensional feeding unit, we use C3 level double nut ball screw produced by Taiwan HIWIN or PMI. Adding preload on both sides can eliminate the accuracy loss caused by the thermal extension.
B．High accuracy, high dynamic response characteristics
The spindle is provided by companies in Taiwan. The Precision angular contact bearing are imported from Japan (or Germany), having high support span, letting the spindle gain high rigidity and high precision.
On Z axis is precisely grinded guide rail casted by hardened iron, on sliding surface is visco-plastic material. The dynamic and static friction coefficients are close to each other, reducing the low-speed crawling phenomenon of the machine. It also has high positioning accuracy and high dynamic responsive characteristics.
C. Great thermal stability
The main motor is located in the middle of the spindlebox, having symmetric stress and thermal deformation. This machine has good thermal stability .
A thermostat oil cooling system is optional for the spindle: in order to improve the machining accuracy, we adopt the external cooling pump for the outer sleeve of the spindle to cool with automatic cycling thin oil.
D. High efficiency
The maximum spindle speed can reach 12000 rpm, the X/Y/Z- axis rapid travel rate can reach 36m/min.
In the automatic cycle of the machine, it’s possible to manually loading and unloading the tool in tool magazine, the tool to tool changing time can reach 2.9sec.
E. Superior quality
We request for high quality throughout the whole production process. All the parts are inspected and tested. The data plays an important role in the product development, to ensure the quality of each machine we product, we WNC constantly optimize the engineering technology, design and manufacturing method through continuous data monitoring and data collection.
F. Large torque
We use the servo spindle motorβiI 12/8000(11/15KW) as the standard configuration, the output torque can reach 95Nm.
