New Product (15) – Vertical Machining Center VMC855 from WMTCNC China

This Vertical Machining Center VMC855 is suitable for mechanical processing and mold making. And it can adapt to the processing requirement from rough machining to finish machining. It can also finish many working procedures like milling, drilling, tapping, boring, etc.

This cnc milling machine’s X, Y, Z three axes are servo direct control semi-closed-loop vertical machining centers. The three axes are all linear ball guide rails. The guide rails have a large load, wide span, and high accuracy. Reasonably, the spindle is driven by a servo motor through a synchronous belt. It can realize the clamping of various discs, plates, shells, cams, molds and other complex parts at one time, and can complete various processes such as drilling, milling, boring, expanding, reaming, rigid tapping, etc., which is suitable for many varieties, The production of small and medium batch products can meet the processing of complex and high-precision parts. It can be equipped with a fourth rotation axis to meet the processing requirements of special parts.

Machine Features

1. HT300 cast iron is used for the main foundation parts such as the base, the slide, the work table, the column, the spindle box, etc .; the base is a box structure, and the compact and reasonable symmetrical rib structure ensures the high rigidity and bending and shock absorption performance of the foundation parts; A The bridge-span column and internal grid-like ribs strongly ensure the rigidity and accuracy of the Z-axis strong cutting; the basic parts are molded with resin sand and subjected to aging treatment, which provides a guarantee for the stability of the machine tool’s long-term use performance.

2. The X, Y, Z three-way guides are all Taiwan ball linear guides, which have the characteristics of fast speed, high rigidity, low friction, low noise, low temperature rise, and other changes, and cooperate with automatic forced lubrication to improve the accuracy and life of the machine tool.

3. The Z-direction counterweight is balanced to ensure smooth and stable movement of the spindle box; the Z-direction drive motor has a power-loss brake device.

4.Adopt high-speed, high-precision, high-rigidity spindle unit, strong axial and radial bearing capacity, the maximum speed can reach 8000rpm.

5. The main shaft adopts a central blowing structure. When the main shaft is released, the central high-pressure gas is used to quickly clean the inner cone of the main shaft to ensure the accuracy and life of the tool clamping.

6.The external protection of the machine tool is designed with a full protection structure, which is convenient to operate, safe and reliable, and beautiful.

7. Adopt reliable centralized automatic lubricating device, regularly and quantitatively automatically lubricate each lubrication point of the machine tool, and adjust the lubrication time according to the working conditions.
