XH850 Vertical Machining Center

1、 Product Introduction and Usage
This product is a semi closed loop vertical machining center with X, Y, and Z three-axis servo direct control. All three axes are rectangular rails with wide guide rails and large spans. The structure and external dimensions are compact and reasonable, and the spindle is driven by a servo motor through a synchronous belt. It can achieve one-time clamping of various complex parts such as disks, plates, shells, camshafts, molds, etc. It can complete various processes such as drilling, milling, boring, expanding, reaming, and rigid tapping, suitable for the production of multiple varieties and small to medium batch products, and can meet the processing of complex and high-precision parts.
Can be equipped with a fourth rotation axis to meet the processing requirements of special parts.
2、 Main structural features
1. The main foundation components such as the base, slide, worktable, column, and spindle box are made of HT300 cast iron; The base and slide are both box type structures, and the compact and reasonable symmetrical reinforcement structure ensures the high rigidity and bending and shock absorption performance of the foundation components; The A-type bridge span column and internal grid like reinforcement effectively ensure the rigidity and accuracy during Z-axis strong cutting; The basic components are molded with resin sand and undergo aging treatment, providing stability for the long-term performance of the machine tool.
2. The X, Y, and Z guide rails are widened rectangular sliding rails that have undergone intermediate frequency quenching and precision grinding; Cooperate with automatic forced lubrication to reduce the frictional resistance of feed motion, minimize low-speed crawling, and improve the precision and lifespan of the machine tool;
3. Add counterweights in the Z direction to balance and ensure smooth and stable movement of the spindle box; The Z-direction drive motor has a power-off braking device;
4. The X, Y, and Z directions are fed using high-precision and high-strength internal circulation double nut preloaded ball screws with high feed rates; 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. Adopting high-speed, high-precision, and high rigidity spindle units, with strong axial and radial bearing capacity, and a maximum speed of up to 8000rpm;
6. The spindle adopts a central blowing structure, which quickly cleans the inner cone of the spindle with central high-pressure gas when the spindle loosens, ensuring the accuracy and service life of tool clamping;
7. The X, Y, and Z direction guide rails and lead screws are all equipped with fully enclosed protective devices to ensure the cleanliness of the lead 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 fully protective structure design, which is easy to operate, safe and reliable;
9. Using a reliable centralized automatic lubrication device, automatic intermittent lubrication is applied to each lubrication point of the machine tool in a timed and quantitative manner, and the lubrication time can be adjusted according to the working conditions;
10. Using 24 disc cutter magazines produced by professional manufacturers 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; The knife magazine movement is equipped with a damping structure, which can reduce the impact during movement and ensure the service life of the knife magazine; Pneumatic drive, easy to use, shortest path for tool change;
11. By using an oil-water separation device, most of the collected lubricating oil can be separated from the coolant, preventing rapid deterioration of the coolant and promoting environmental protection;
12. The machine tool operating system adopts ergonomic principles, with an independently designed control box that can rotate on its own and is easy to operate.
