Multi-axis CNC gantry drilling machine CJH6010M
Use of machine tool:
Multi-axis CNC gantry drilling machine is mainly used for drilling and tapping of regular and dense hole workpieces such as sieve plates, wear-resistant plates, optical platforms, etc. The multi-axis CNC drilling machine is a gantry moving drilling machine with a double gantry multi-spindle structure. The equipment is equipped with 16 spindles as standard, which can form 16 holes at a time and has high processing efficiency.
Features of machine tools:
1. The worktable and gantry are steel plate welded box structure, and the overall structure is stabilized by aging heat treatment; two ball guide rail pairs are installed on the front side of the gantry, and a transverse sliding saddle is installed; a ball screw pair is installed between the sliding saddle and the guide rail, which is driven by a servo motor to achieve Y-axis positioning.
2. The multi-axis CNC gantry drilling machine adopts CNC sliding pillow power head (Z-axis). The stroke is pre-set according to the workpiece, which can realize the automatic conversion of the drill bit fast-forward-forward-forward. It has the advantages of high processing efficiency, simple structure and low maintenance cost. The spindle adopts BT40 rigid precision spindle, and carbide drills can be used for high accuracy. Equipped with a tool cylinder, it is extremely convenient to load and unload tools.
3. There are a total of 12 CNC axes in the multi-axis CNC gantry drilling machine: the movement of the gantry (2 x axes); the movement of the power head on the gantry beam (2 y-axis); the feed movement of the power head (8 z-axis). Each CNC shaft is guided by a precision linear rolling guide rail. The X axis is driven by a servo motor + reducer through a precision gear rack pair, and the Y and Z axes are driven by a servo motor + ball screw pair. Flexible movement and accurate positioning.
4. The numerical control system is controlled by a Guangzhou 988 numerical control system. The drilling coordinates can realize the direct conversion of CAD/CAM. It is equipped with USB interface, RS232 interface and LCD screen, which facilitates programming, storage, display and communication. The operation interface has inaccuracy error compensation, automatic alarm and other functions. It has the function of preview and re-examination of the hole before drilling, which is easy to operate.
