XK-7145Pre sales materials for CNC milling machines

1CNC milling machineProduct Introduction and Usage

This product isX. The Y and Z three-axis servo controlled semi closed loop vertical CNC milling machine has a compact and reasonable structure and external dimensions, and the spindle is driven by servo motor power. It can achieve one-time clamping of various complex parts such as disks, plates, shells, cams, 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 batch products, and can meet the processing of complex and high-precision parts.

IICNC milling machineMain structural features

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. The reinforcement is arranged reasonably 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 movement of the spindle;

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 main shaft adopts a floating tension knife structure and a Taiwanese booster cylinder. When loosening the knife, the main shaft bearing is not subjected to force, which extends the bearing life. The main shaft adopts a high torque synchronous toothed belt transmission, with zero slip, no friction, and low noise;

7. Using high-precision laser interferometers to detect and compensate for screw pitch errors and clearances;

8. 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;

9. The machine tool protection adopts a fully enclosed mechanism design; safe and reliable Equipped with high-pressure, high head, and high flow cooling pumps and air guns for cooling and cleaning workpieces

10Equipped 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.

11The 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.

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

13. The machine tool operating system is designed based on ergonomic principles, with an independent control box that can rotate on its own, making it easy to operate;
