8. CNC sliding pillow-type power head is mounted on two sets of horizontally moving skateboards. The Y-axis movement of the pillow-type drilling power head is guided by two linear guides to ensure high precision in operation.
9. Vertical CNC feed slider type power head, the spindle motor of the power head adopts a spindle-specific servo motor driven by a synchronous belt, 1-2, low-speed torque, can withstand heavy cutting loads, and is also suitable for high-speed machining of hard alloy cutting tools. Realize the integration of drilling and milling.
10. The power head spindle adopts Precision Spindle (high-speed internal cooling) brand "KENTURN" from Taiwan, with a spindle taper BT50, featuring a butterfly spring hydraulic puller mechanism, and an air-liquid cylinder for loosening and grasping the tool, replacing the tool very convenient. It can be equipped with hard alloy internal cooling drills and high-speed steel Fried Dough Twists and has a spindle taper cleaning function.


11. High-quality casting workbench and bed-integrated design. Increased equipment rigidity. Several horizontal T-shaped groove strips can be machined on the workbench, and the workpiece can be pressed tightly with a pressure plate through the T-shaped grooves.
Optional: The working table can be equipped with a Self-centering hydraulic clamping device, which can quickly and automatically clamp the tube plate.
12. The machine is equipped with an electronic handwheel operation system for edge inspection and positioning of workpieces. After setting the feed position for drilling the first hole, the program of fast feed → working feed → fast retreat can be implemented for drilling the remaining holes, thus saving a significant amount of time during the machining process and greatly improving production efficiency. Additionally, it also features automatic chip breaking, chip removal, and pause functions.
13. This machine is equipped with a flat chain automatic chip conveyor and a chip collection cart for the automatic collection of iron chips.
14. The cooling system is equipped with a high-pressure internal cooling pump and a low-pressure external cooling pump, which can be used for internal or external cooling of the cutting tools. The cooling fluid is forced to circulate.
15. This machine is equipped with a centralized lubrication device, which can automatically lubricate various moving components such as guide rails, screw threads, bearings, and other moving pairs.
16. The X-axis of the machine is equipped with a stainless steel protective cover, and the Y-axis is equipped with flexible protective covers on both sides. A waterproof sheet metal system is installed around the workbench.
17. This machine tool is equipped with LED machine lights, which are conducive to observation and operation. An air gun is installed on the front side of the machine body, facilitating the cleaning of iron chips on the workbench.
18. The machine is equipped with a photoelectric edge detector, which facilitates the alignment of the workpiece position.
19. This machine tool is equipped with a nitrogen balancing system to achieve hydraulic balance for the vertical ram.
20. The CNC operating system of this machine is installed on the right side of the gantry and can move longitudinally along with the gantry, making the operation convenient.
21. The CNC system of this machine tool adopts a full set of Siemens 808D bus version control systems, equipped with RS232 interface and LCD display screen. The drilling coordinates can achieve direct conversion between CAD/CAM, which facilitates programming, storage, display, and communication. The operation interface features human-machine dialogue, error compensation, automatic alarm, and other functions.
22. This machine is equipped with our company's self-developed CAD drawing conversion software, eliminating the need for manual programming for drilling. The workpiece hole positions can be inputted via the keyboard or CAD floppy disk, and the processing program will be automatically generated. It features pre-drilling hole position preview and recheck functions, making operation convenient.
