VMC330 Pre-sales information for Vertical Machining Center
Thank you for your company's attention to our products.
Jiangsu Daxiang Intelligent Equipment Co., Ltd. is a company specializing in the production of CNC machine tools!!
I. Product Introduction and Application
This product is a semi-closed-loop vertical machining center with three-axis servo direct-coupled control for X , Y , Z axes. All three axes use steel ball rolling linear guides, which have large load capacity, wide span, and high precision. The XYZ three directions use 20MM linear guides. The structure and overall dimensions are compact and reasonable. The spindle is driven by a servo motor through a synchronous belt , which can realize one-time clamping of various complex parts such as discs, plates, shells, cams, and molds, and can complete various machining processes such as drilling, milling, boring, reaming, counterboring, and rigid tapping. It is suitable for the production of multi-variety and small-to-medium-batch products and can meet the machining requirements of complex and high-precision parts.
II. Main Structural Features
1. The main basic components such as the base, slide, workbench, 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 the high rigidity and anti-bending and shock-absorbing performance of the basic components. The A -shaped bridge-type column and the internal grid-shaped ribs effectively ensure the rigidity and precision during heavy cutting of the Z axis. The basic components are molded by resin sand and subjected to aging treatment, which provides a guarantee for the long-term stability of the machine tool's performance.
2. X , Y , Z The guide rails in all directions are linear ball guide rails from Taiwan HIWIN Company. They feature high speed, high rigidity, low friction, low noise, and low temperature rise variation. Combined with automatic forced lubrication, they improve the accuracy and service life of the machine tool.
3、 Z direction is equipped with a counterweight block for balance, ensuring smooth and stable movement of the headstock; The driving motor in the Z direction is equipped with a power-off braking device.
4、 X 、 Y 、 Z directions use high-precision and high-strength internal circulation double-nut preloaded large-lead ball screws for feed, with high feed speed. The driving 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, and high-rigidity spindle unit is adopted, with strong axial and radial load-bearing capacity. The rotational speed can reach 8000rpm .
6、 The spindle adopts a central air-blowing structure. When the spindle releases the tool, high-pressure central gas is used to quickly clean the inner taper of the spindle, ensuring the accuracy and service life of tool clamping.
7、 X 、 Y 、 Z directions' 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, 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, reliable, and aesthetically pleasing.
9、 A reliable centralized automatic lubrication device is adopted to automatically lubricate each lubrication point of the machine tool intermittently at regular time and in fixed quantity. The lubrication time can be adjusted according to the working conditions;
10、 A 6- or 8-pocket turret tool magazine produced by a professional manufacturer is adopted. 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 can change tools through the shortest path;
11、 An oil-water separation device is adopted, 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 operating box is independently designed and can rotate by itself, which is convenient to operate.
