M400 cheap siemens 808D system servo motor cnc vertical milling center

  Features:

1. The main structure of the bed and columns, etc. using reasonable fabric reinforcement enhanced shock resistance.
2. Under heavy cutting without distortion and smooth chip design.
3. The three-axis linear guide installation and maintain long-term operation with high precision at high speed down. Fast moving shorten positioning time increase productivity.
4. Precision constructed press-fit automatic lubricating device, use the ball screw with a special bearing, yet the positioning accuracy and precision contour control and move the shaft rigidity.
5. The three-axis are servo feed axes, spindle and servo motor with rigid tapping function, improve processing accuracy, reduce processing time and improve productivity.
6. The system can produce according to the customer's choice.

Product Overview
1.The overall structure of high toughness, high-level cast iron, and after annealing can efficiently and effectively eliminate the stress within the material, to ensure the best accuracy and stability and durability.
2.Column design with a large "human" type large span, high rigidity and high stability, and strong, smooth casting large bed base is connected to better ensure the accuracy of the workpiece, and accuracy.
3. The weight system in the column, and a biaxially oriented, so cutting down headstock move more smoothly and effectively suppress vibrations produce adverse effects, to ensure accuracy.
4.Three-axis P3 level precision ball screw, nut washer with dual pretensioners, pre eliminate backlash and achieve high positioning accuracy and stability of the repeat positioning accuracy.
5-axis machine-precision linear guides are installed to ensure that the processing of high-precision, while increasing the fast forward speed.
6.Three-axis feed drive by AC servo motor and screw directly connected, smooth transmission, no backlash. Also has good stiffness and damping performance, which greatly improves the dynamic rigidity driveline.
7.Precision high-speed spindle unit with AC servo motor through belt linked, low noise, low vibration, low heat. Can be milling, drilling, reaming, boring, reaming, tapping and other processing.
8.Column Z axis travel large (up to 500mm), so that the processing of high workpieces without the big machine is complete, at the same time to increase the fourth indexing shaft, leaving enough space.
9.Sheet metal integrated design, comprehensive protection, good integrity, high tightness. Open sliding door design, easier loading and unloading of the workpiece.
