High Precision CNC Vertical Machining Center VMC855

  • This product is a semi-closed-loop vertical machining center with servo direct control of X, Y, and Z axes. The X, Y, and Z axes are roller linear guides. The guide rails are wide, have a large span, and have a compact structure. The spindle is driven by a servo motor through a synchronous belt. 
  • It can realize one-time clamping of various complex parts such as disks, plates, shells, cams, and molds, and can complete various processes such as drilling, milling, boring, expanding, reaming, and rigid tapping. 
  • It is suitable for the production of multiple varieties and small and medium-sized batches of products, and can meet the processing of complex and high-precision parts. It can be equipped with a fourth rotating axis to meet the processing requirements of special parts.

Features

  • The main basic parts such as base, slide seat, workbench, column, spindle box and so on are made of HT300 cast iron; the base and slide seat are box-type structures, and the compact and reasonable symmetrical rib structure ensures high rigidity, bending resistance and shock absorption. The A-shaped bridge-span column and internal grid-like ribs effectively ensure the rigidity and accuracy during strong Z-axis cutting; the basic parts are made of resin sand and have undergone aging treatment, which guarantees the stability of the long-term performance of the machine tool.

  • The X, Y, and Z axes all use linear roller guides, combined with automatic forced lubrication, to reduce the frictional resistance of the feed motion, reduce low-speed crawling, and improve the accuracy and life of the machine tool.

  • The Z-direction drive motor adopts high torque drive and has a power-off braking device.

  • The feeds in the three directions of X, Y and Z adopt high-speed and silent ball screws; The drive motor is directly connected to the screw through an elastic coupling, and the feed servo motor directly transmits power to the high-precision ball screw without backlash, ensuring the positioning accuracy and synchronization of the machine tool;

  • It adopts a high-speed, high-precision and high-rigidity spindle unit with strong axial and radial load-bearing capacity, and the maximum speed can reach 8000rpm;

  • The spindle adopts a central air blowing structure. When the spindle releases the tool, the central high-pressure gas is quickly used to clean the inner cone of the spindle to ensure the accuracy and life of the tool clamping;

  • The guide rails and screws in the three directions of X, Y, and Z all adopt fully enclosed protective devices to ensure the cleanliness of the screws and guide rails and the transmission and movement accuracy and life of the machine tool;

  • The machine tool adopts a fully protective structure design, which is easy to operate, safe and reliable;

  • Use a reliable centralized automatic lubrication device to automatically lubricate each lubrication point of the machine tool intermittently and quantitatively, and the lubrication time can be adjusted according to the working conditions;

  • Adopt 24 disc tool magazines produced by Taiwanese professional manufacturers, which have the advantages of accurate tool change, short time, high efficiency and high reliability; the tool magazine movement has a damping structure, which can reduce the impact during movement and ensure the use of the tool magazine Long life; pneumatic drive, easy to use, shortest path tool change;

  • The machine tool operating system adopts ergonomic principles. The operating box is independently designed and can rotate by itself, making it easy to operate.
