Product description
Vertical machining centers are mainly used in mechanical processing industries such as military, aerospace, automobile, mold, and instrumentation to process various parts with high precision, multiple processes, and complex shapes. This type of machine tools can be used for small and medium-sized batches and multiple varieties of production, and can also be used in automatic lines for mass production. With the changes in the market, the changes and updates of products of various professional manufacturers are also accelerating, which requires machine tools to also have such functions, and vertical machining centers can exactly meet such functions. Using this machine tool can save process equipment and shorten the time Production preparation cycle, ensuring parts processing quality, and improving production efficiency.
In order to adapt to market demand, our company developed the vertical machining center VMC855. The machine tool adopts an electromechanical integrated structure, with a compact and reasonable overall layout, a small footprint, and easy installation and maintenance. The machine tool worktable performs cross slide movement, a single column is equipped with a high-speed spindle to realize third-axis movement, powerful tool cooling and chip removal functions, and reliable personal and equipment safety protection measures. The machine tool adopts a closed protective structure, which is beneficial to safe production and reduces pollution to the production environment. The key purchased parts of this machine tool are imported components, making the whole machine highly reliable and durable.

Structural features
1.Castings
The castings of this machine tool are all cast with resin sand and have been artificially aged twice. They have good stability, high strength and stable and reliable accuracy.
2. Spindle
The entire spindle system selected for this machine tool is imported from Taiwan's professional manufacturing supporting manufacturers. All important parts have been strengthened. It uses high-precision spindle special bearings from world-renowned manufacturers and is lubricated with NBU15 grease. After the entire spindle is assembled under constant temperature conditions, All need to pass computer balance correction and running-in testing, so that the entire spindle has a long service life and high reliability. The spindle motor of this machine tool is connected to the spindle pulley through a special high-speed arc toothed belt to complete the main transmission system.
3. Lead screw
The ball screws driving the X, Y, and Z axes of this machine tool all use high-precision preloaded ball screws provided by Taiwan's professional supporting manufacturers. The bearings at both ends of the ball screw are imported P4-level paired combination ball screws for special purposes. bearings. The coupling adopts imported coupling, which makes the three-axis transmission rigid and the accuracy stable and reliable.
4. Feeding system
The feed system of this machine tool adopts a servo motor directly connected to the ball screw through an elastic coupling to drive the work.
The table, sliding saddle and spindle box realize feed in the X, Y and Z directions.
