XK620 CNC milling machine | Small CNC drilling and milling machine details

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 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; 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 box;

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, the maximum speed can reach 6000rpm;

6. The X, Y, and Z direction guide rails and lead screws are equipped with 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;

7. The external protection of the machine tool adopts a semi protective structure design, which is easy to operate, safe and reliable;

8. 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;
