650 Small Cnc Vertical Machining Center, Jiangsu Daxiang 650 Machining Center
VMC650L Vertical Machining Center Information
I. Product Introduction and Application
This product is a semi-closed-loop vertical machining center with three-axis servo direct-coupled control for the X , Y , and Z axes. All three axes are equipped with steel ball rolling linear guides, which have large load capacity, wide span, and high precision. The XY direction uses 35MM heavy-duty guides, and the Z direction uses 45MM heavy-duty guides. Only the TOM-L850 of other manufacturers uses linear guides of this specification. The structure and overall dimensions are compact and reasonable. The spindle is driven by a servo motor through a synchronous belt. It can realize one-time clamping of various complex parts such as discs, plates, shells, cams, and molds, and can complete multiple processing operations such as drilling, milling, boring, expanding, reaming, and rigid tapping. It is suitable for the production of multi-variety and small-to-medium batch products and can meet the processing requirements for complex and high-precision parts. It can be equipped with a fourth rotary axis to meet the processing requirements of special parts.
II. Main Structural Features
1. The main basic parts such as the base, slide, worktable, column, and spindle box are made of HT300 cast iron. The base has a box-type structure, and the compact and reasonable symmetrical rib structure ensures high rigidity and anti-bending and shock-absorbing performance of the basic parts. The A -type bridge-span column and the internal grid-shaped ribs effectively ensure the rigidity and precision during heavy cutting of the Z axis. The basic parts are made by resin sand molding and have undergone aging treatment, which provides a guarantee for the long-term performance stability of the machine tool.
2. X , Y 、 Z axis guide rails are all heavy-duty linear ball guide rails from HIWIN Corporation in Taiwan. They feature high speed, high rigidity, low friction, low noise, and low temperature rise variation. With automatic forced lubrication, they improve the accuracy and service life of the machine tool.
3、 Z axis is balanced with counterweights to ensure smooth and stable movement of the headstock. The Z-axis drive motor is equipped with a power-off braking device.
4、 X 、 Y 、 Z axes use high-precision, high-strength internal circulation double-nut preloaded large-lead ball screws for feed, with high feed speed. The drive motor is directly connected to the screw through an elastic coupling. 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.
5、 A high-speed, high-precision, high-rigidity spindle unit is adopted, with strong axial and radial load-bearing capacity. The rotational speed can reach 8000rpm.
6、 The spindle uses a central air blowing structure. When the spindle releases the tool, the central high-pressure gas quickly cleans the inner taper of the spindle to ensure the accuracy and service life of tool clamping.
7、 X 、 Y 、 Z axes' guide rails and screws are all equipped with protective devices to ensure the cleanliness of the screws and guide rails, and to ensure the transmission, movement accuracy, and service life of the machine tool.
8、 The external protection of the machine tool adopts a full-protection structure design, which is convenient to operate, safe, reliable, and aesthetically pleasing.
9、 Adopt a reliable centralized automatic lubrication device to automatically lubricate each lubrication point of the machine tool intermittently at regular time and quantity. The lubrication time can be adjusted according to the working conditions;
10、 Adopt a tool magazine with 16 tools of the hat type (standard configuration) or a disc type tool magazine with 16 tools produced by a professional manufacturer in Taiwan. The tool change is accurate, the time is short, and the efficiency is high. After millions of operation tests, it meets the reliability requirements; It is equipped with a damping structure to reduce the impact during movement and ensure the service life of the tool magazine; It is pneumatically driven, easy to use, and can change tools through the shortest path;
11、 Adopt an oil-water separation device, which can separate most of the collected lubricating oil from the coolant, prevent the rapid deterioration of the coolant, and is beneficial to environmental protection;
12、 The machine tool operating system adopts the principle of ergonomics. The operation box is independently designed and can rotate by itself, which is convenient for operation.
