1、 Introduction and Application of XK850c CNC Milling Machine

The feed axis of this series of machining centers isX. Y and Z coordinate control, with the spindle driven by servo motor power. It can achieve one-time clamping of various complex parts such as disks, plates, shells, camshafts, molds, etc., and complete various processes such as drilling, milling, boring, expanding, reaming, tapping, etc. It is suitable for the production of multiple varieties and small to medium batches of products, and can better demonstrate its superiority in the processing of complex and high-precision parts.

2、 Main structural characteristics of XK850c CNC milling machine

1. The main foundation components such as the base, slider, worktable, column, and spindle box are made of high rigidity cast iron structure, with reinforcing ribs distributed in a mesh structure inside to ensure the high rigidity and bending and shock absorption performance of the foundation components; The basic components are molded with resin sand and undergo aging treatment to ensure the stability of the long-term accuracy of the machine tool, providing a guarantee for the stability of the machine tool performance.

2. The X, Y, and Z guide rails are widened rectangular sliding rails that have undergone intermediate frequency quenching and precision grinding; The sliding guide surface is coated with composite PTFE material and finely scraped, combined with automatic forced lubrication, to reduce the frictional resistance of feed motion, reduce low-speed crawling, and improve the accuracy and service life of the machine tool;

3. Add counterweights in the Z direction to balance and ensure smooth and stable spindle movement;

4. The X, Y, and Z directions are fed using high-precision and high-strength C3 grade double nut pre tightened ball screws provided by professional Taiwanese manufacturers HIWIN or PMI. The feed speed is high, and the bearings at both ends of the screw are imported P4 grade 60 ° contact angle matched ball screw special bearings. The three-axis ball screws are all pre stretched; The drive motor is directly connected to the screw through a German specific precision coupling, and the feed servo motor directly transmits power to the high-precision ball screw without backlash, ensuring the positioning accuracy of the machine tool;

5. Using well-known Taiwanese brand high-speed, high-precision, and high rigidity spindle units, the bearings adopt P4 grade imported spindle special bearings. After the entire spindle is assembled under constant temperature conditions, it has passed dynamic balance calibration running and testing, with strong axial and radial bearing capacity and a speed of up to 8000rpm;

6. The spindle tool changing and cutting adopt a floating unloading mechanism to reduce the impact on the spindle bearing during cutting, improve the service life of the bearing, and ensure the accuracy of high-speed operation of the spindle;

7. The X, Y, and Z direction guide rails and lead screws are all enclosed and protected to ensure the cleanliness of the lead screws and guide rails, and to ensure the transmission and motion accuracy of the machine tool;

8. The machine tool protection adopts a fully enclosed mechanism design; safe and reliable

9. Equipped with a large flow cooling pump to fully ensure circulating cooling. The end face of the spindle box is equipped with cooling water nozzles and air nozzles, which can be water-cooled or air-cooled. It is also equipped with a cleaning air gun for cleaning the machine tool.

10The pneumatic system uses a pneumatic triad to filter impurities and moisture in the gas source, and the solenoid valve group passes through itPLCProgram control ensures fast and accurate completion of actions such as spindle loosening, tool clamping, and tool air cooling.

11. The chip removal system adopts high-pressure chip flushing, automatic spiral chip discharger or chain plate (optional), and manual iron chip car to reduce the labor intensity of operators, reduce processing assistance time, and improve work efficiency;

12. The machine tool operating system is designed based on ergonomic principles, with an independent control box located close to the operator. It is equipped with a handheld electronic handwheel control box for easy tool alignment;

13. Adopting advanced centralized automatic lubrication device, timed and quantitative automatic intermittent lubrication, stable and reliable operation;

14Famous imported machine tool accessoriesCNC control system, fully functional, easy to operate, stable and reliable accuracy;

15. The electrical system adopts a design structure that separates transformers from control systems, reducing heat generation, minimizing temperature changes in electrical boxes, improving the service life of electrical components, and enhancing the reliability of system control;

16. The spindle adopts a high-performance temperature control system, which takes away the heat generated by the spindle and maintains a balance between the spindle unit temperature and room temperature, greatly reducing the impact of thermal deformation on the spindle rotation accuracy and extending the service life of the spindle; The spindle adopts a central blowing structure, which quickly cleans the inner cone of the spindle with central high-pressure gas after loosening the tool, ensuring the accuracy of tool clamping; (Optional)

17. Use high-precision laser interferometers imported from the United States to detect and compensate for screw pitch errors and clearances; Simultaneously using Renishaw ball bar for circular inspection has improved the accuracy and quality of the machine tool.
