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

TIANCHEN LJVHS-CNC-7000

CNC Laser-Equipped Sawing and Machining Center for Aluminum

Machine Technical Specifications

☆ The machine consists of three main zones: a loading zone, a machining zone, and an unloading zone.

☆ The machining zone comprises two independent modules: a drilling/milling module and a sawing module.

☆ Capable of sawing and milling reinforced mullions.

☆ Capable of sawing and milling frames.

☆ Capable of sawing and milling ultra-narrow profiles.

☆ The sawing module enables efficient, continuous cutting of aluminum profiles at compound angles—45°, 90°, and 135°—as well as at any arbitrary angle within the 45° to 135° range.

☆ The drilling/milling module is positioned on the feed side. High-power milling spindles are installed above, below, in front of, and behind the profile. A laser marking unit is located at the front, while a laser milling unit is positioned at the rear.

☆ The four high-power milling spindles are equipped with servo-driven X, Y, and Z axes. The X-axis servo drive provides an extended travel range for milling, allowing for the simultaneous machining of holes and slots on all four sides, as well as integrated milling and sawing operations.

☆ In addition to the X, Y, and Z servo axes, the front electric spindle features an independent fourth rotary servo axis. This facilitates automated machining with obstacle avoidance for angled components—such as concealed drainage slots, pressure-equalization holes, and standard drainage slots. ☆ The milling units and laser heads are positioned in parallel along the X-axis, allowing for seamless switching between laser and milling operations.

☆ Both the milling units and the rear laser cutting unit can perform horizontal (0°) machining as well as angled machining at 10° and 15°, enabling the system to automatically navigate around inclined pin holes and other specific features.

☆ A fixed rear reference surface is integrated into the table for clamping and positioning the profile during cutting, ensuring maximum cutting precision.

☆ The profile clamping system features dual-level clamps and specialized hold-down devices for inward-opening casement profiles, guaranteeing high positioning stability for tall profiles.

☆ The table is capable of horizontal movement, which facilitates the removal of offcuts (from the ends of the workpiece), allows for the safe return stroke of the saw blade—preventing contact between the blade and the workpiece—and extends the service life of the saw blade.

☆ The combination of horizontal table movement and the saw head enables the cutting of corner connectors for casement sashes.

☆ The work surface is equipped with a pneumatic floating system that enhances positioning accuracy, cleans and cools the underside of the profile during feeding, provides micro-floating movement for greater stability, and prevents the protective film from peeling off.

☆ The feeding mechanism includes a flipping function for ultra-narrow workpieces; it is designed for the horizontal transport and vertical cutting of tall, thin workpieces or profiles with complex cross-sections.

☆ The drilling and milling module features a compact design, which minimizes profile overhang during processing.

☆ A maintenance passage is provided between the milling module and the feeding mechanism, facilitating tool changes and routine maintenance. ☆ The integrated design includes a centralized dust and chip extraction system.

This effectively prevents aluminum chips and waste from falling onto the floor, ensures the separation of chips, and maintains a clean production environment.

☆ An automated barcode (QR code) printing and labeling system is installed for the automatic marking of profiles; it is compatible with the E-Work digital factory system.

☆ The laser cutting unit features a servo-driven focus adjustment mechanism to accommodate profiles with various cross-sections.

☆ Moving components utilize high-precision linear guides to ensure smooth motion and maintain processing accuracy.

☆ The robotic feeding arm is servo-driven and features automatic control across the X, Y, and Z axes; the profile clamping mechanism is adaptable to different cross-sections. A high-precision rack-and-pinion system is used for accurate profile feeding.

☆ The saw unit employs a direct-drive motor, ensuring stable cutting and high processing precision. The sawing operation is controlled by a servo system, which manages rapid approach, working feed, and rapid retraction to enhance productivity.

☆ A high-precision CNC system ensures stable and reliable machine operation.

☆ A servo-driven robotic unloading arm facilitates rapid unloading and positioning, and supports the automatic discharge of short workpieces (from 200 mm in length).

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

☆ A high-resolution camera and an LCD display are provided for real-time visual monitoring of the processing operation.

☆ A dedicated air compressor is included for the laser cutting process to ensure cutting precision.

☆ The package includes a water cooling unit designed specifically for the laser, which ensures stable system operation.
