VMC550 Pre-sales information for Vertical Machining Center
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 XYZ directions feature a heavy load of 35MM , and the structure and overall dimensions are compact and reasonable. The spindle is driven by a servo motor through a synchronous belt. It can achieve one-time clamping of various complex parts such as discs, plates, shells, cams, and molds, and can complete multiple processes including drilling, milling, boring, reaming, expanding, and rigid tapping. It is suitable for the production of multi-variety, 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 components such as the base, slide, worktable, column, and spindle box are made of HT250 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 components. The A -type bridge-span column and the internal grid-like ribs effectively ensure the rigidity and accuracy of the Z axis during heavy cutting. The basic components are made by resin sand molding and have undergone aging treatment, which guarantees the long-term stability of the machine tool's performance.
2. The X , Y , and Z direction guides are all heavy-duty linear ball guides from HIWIN Company in Taiwan. They have characteristics such as high speed, high rigidity, low friction, low noise, and low temperature rise change. Combined with automatic forced lubrication, they improve the accuracy and service life of the machine tool. Z direction is balanced by adding counterweights to ensure smooth and stable movement of the headstock; Z direction drive motor is equipped with a power-off braking device;
4、 X , Y , Z three directions of feed adopt high-precision and high-strength internal circulation double-nut preloaded large-lead ball screws, with high feed speed; 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;
5、 A high-speed, high-precision and high-rigidity spindle unit is adopted, with strong axial and radial load-bearing capacity, and the rotational speed can reach 8000rpm ;
6、 The spindle adopts a central air blowing structure. When the spindle releases the tool, the inner cone of the spindle is quickly cleaned with central high-pressure gas, ensuring the accuracy and service life of tool clamping;
7、 X , Y , Z the guide rails and screws in three directions are all equipped with protective devices to ensure the cleanliness of the screws and guide rails, and to ensure the transmission and motion 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 and reliable, and beautiful;
9、 A reliable centralized automatic lubrication device is adopted 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; It uses a tool magazine produced by a professional manufacturer in Taiwan, with 12 tools in a hat-type (standard configuration) or 16 tools in a disc-type tool magazine (optional). The tool change is accurate, with short time and high efficiency. After millions of operation tests, it meets the reliability requirements. It has a damping structure, which can reduce the impact during movement and ensure the service life of the tool magazine. It is pneumatically driven, easy to use, and changes tools via the shortest path.
11、 It adopts 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.
