TIANCHEN LJVHFT-CNC-7000 LASER Intelligent Cutting&Milling Center

TIANCHEN LJVHFT-CNC-7000

CNC Aluminum Sawing and Machining Center with Integrated Dual-Laser System

Features:

☆ The production line consists of three sections: a loading zone, a machining/cutting zone, and an unloading zone.

☆ The machining zone comprises two independent units: one for drilling and milling, and one for cutting.

☆ Capable of processing reinforced curtain wall (mullion-transom) profiles.

☆ Supports sawing and milling operations for conversion frames.

☆ The cutting unit performs efficient, continuous, and complex sawing of aluminum profiles at angles of 45°, 90°, and 135°. It also supports cutting at any arbitrary angle within the 45°–135° range.

☆ The drilling and milling unit is located on the infeed side of the main machine and is equipped with high-power (6 kW) milling spindles positioned above, below, in front of, and behind the profile. A laser marking device for engraving lines is positioned in front of the profile, while a laser milling spindle is located behind it.

☆ The drilling and milling spindles are aligned parallel to the laser system along the same X-axis position, allowing for seamless switching between laser processing and mechanical milling.

☆ The milling tools and the laser marker can perform horizontal (0°) machining as well as inclined machining at angles of 10°, 20°, and 30°; they are also capable of automatically avoiding specific features on the workpiece.

☆ The milling tools and the laser marker can perform horizontal (0°) machining as well as inclined machining at angles of 10°, 20°, and 30°; they are also capable of automatically avoiding specific features on the workpiece (such as concealed drainage channels). ☆ The worktable features a fixed rear support surface used for clamping and positioning profiles during cutting and machining, which maximizes the precision of these operations.

☆ The horizontal profile-clamping mechanism on the worktable is equipped with a dual-clamp system and a tilt-limiter, ensuring secure positioning for taller profiles and enhancing overall stability.

☆ The worktable includes a horizontal displacement function that activates in tandem with the saw unit during the removal of offcuts and scrap, ensuring smooth discharge. This also prevents the material from rubbing against the saw blade during its return stroke, thereby extending the blade's service life.

☆ The worktable is equipped with an air-cushioning system that cleans and cools the underside of the profile while improving positioning accuracy. During material feeding, a "micro-suspension" (air-cushion) feed mechanism is employed to enhance stability and prevent the protective film on the profiles from peeling or delaminating.

☆ The infeed conveyor includes a flipping feature for narrow profiles, enabling the horizontal transport and vertical cutting of thin, tall profiles or those with complex cross-sections.

☆ The drilling and milling unit features a compact design.

☆ A dedicated access space is provided between the drilling/milling unit and the feeding mechanism to facilitate tool changes and routine maintenance.

☆ The integrated design incorporates a centralized dust and chip extraction system, which effectively contains aluminum chips and offcuts, keeping the production area clean.

☆ An automated barcode (and QR code) printing and labeling system is installed, supporting digital integration with the E-Work factory management system. ☆ The laser milling spindle features a servo-focus function, enabling laser processing of profiles with various cross-sectional shapes.

☆ All moving components are equipped with high-precision linear guides, ensuring smooth operation and processing accuracy.

☆ The feeding manipulator utilizes a servo motor for automated control across the X, Y, and Z axes; it can automatically clamp profiles based on their specific cross-section. A high-precision rack-and-pinion drive is also employed to guarantee feeding accuracy.

☆ The cutting blade is directly coupled to the motor, ensuring smooth cuts and high processing precision. The servo-driven sawing mechanism facilitates rapid forward movement, the actual cutting stroke, and a quick return, thereby enhancing processing efficiency.

☆ A high-precision CNC system ensures stable machine performance.

☆ The servo-driven unloading manipulator enables rapid part removal and positioning, including the automatic discharge of short workpieces (with a minimum length of 200 mm).

☆ Linear guides and ball screws are equipped with an automatic lubrication system, which improves operational precision and extends component service life.

☆ A high-resolution camera and an LCD monitor are included, allowing for real-time observation of the cutting and milling processes.

☆ The system comes with a specialized laser compressor, which helps maintain milling precision.

☆ A dedicated water-cooling unit is included to ensure the stable operation of the laser system.
