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 are of 35MM heavy load. 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 for various complex parts such as discs, plates, housings, cams, and molds, and can complete multiple processes 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 for 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-shaped ribs effectively ensure the rigidity and precision during heavy cutting of the Z axis. The basic components are made by resin sand molding and have undergone aging treatment, which provides a guarantee for the long-term stability of the machine tool's performance.
2. The guides in the X , Y , and Z directions 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. With automatic forced lubrication, the precision and service life of the machine tool are improved.
3、 Balance the Z axis by adding counterweights to ensure smooth and stable movement of the headstock; The Z axis drive motor is equipped with a power-off braking device;
4、 The three axes of X , Y , and Z use high-precision and high-strength internal circulation double-nut preloaded large lead ball screws for 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、 Adopt a high-speed, high-precision, and high-rigidity spindle unit 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 high-pressure central gas, ensuring the accuracy and service life of tool clamping;
7、 The guide rails and screws of the three axes of X , Y , and Z 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 and reliable, and aesthetically pleasing;
9、 Adopt a reliable centralized automatic lubrication device to automatically and intermittently lubricate each lubrication point of the machine tool at regular intervals and in a fixed quantity. The lubrication time can be adjusted according to the working conditions;
10、 Adopt the 12 -tool hat-type tool magazine (standard configuration) or 16 -tool disc-type tool magazine ( optional ) produced by professional manufacturers in Taiwan. The tool change is accurate, with short time and high efficiency. After millions of operation tests, it meets the reliability requirements. It is equipped with 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 with 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 to operate.
