CNC drilling center KD-812A with two working tables and six drilling groups

Thanks to two independent working tables, it is possible to process two panels at the same time.

The machine is equipped with an industrial computer based on Windows. CAD/CAM control panel with barcode reading capability to increase machine productivity.

Intelligent visual barcode and QR code recognition device on each worktable. Automatically scans and identifies the machining program.

Each working table has 3 drilling groups: 12 - horizontal spindles, 41 - vertical spindle (32 - top, 9 - bottom) and 2 milling units - 1 top (5.5 kW) + 1 bottom (3.5 kW).

In total, 4 milling spindles and 6 drilling groups are installed on two tables for: 106 drilling spindles (82 vertical + 24 horizontal).

The machine can process two panels at the same time, both top and bottom, within one working cycle, thanks to the possibility of drilling from 6 sides.

4 milling spindles - 2x5.5 kW + 2x3.5 kW (top and bottom) for sawing straight and curved grooves.

Automatic workpiece width detection.

Two automatic clamps securely hold workpieces from 200 to 2800 mm in length and reduce the number of regripping operations during drilling. This significantly shortens the working cycle compared with machines equipped with a single clamp. The maximum speed has been increased to 140 m/min.

The minimum workpiece size is 200х45 mm, enabling the drilling of small parts.

The upper routing spindle is equipped with a powerful vertical hold-down system featuring two pressure plates. It improves routing accuracy and prevents damage to the workpiece.

Workpiece positioning on the machine is performed by an automatic side alignment device. After the barcode is scanned, the side alignment device moves as close to the workpiece as its dimensions allow. The workpiece is positioned against the zero reference point on the X-axis, while the side alignment device aligns it along the Y-axis. Two pneumatic grippers then transfer the workpiece into the machine’s working area for further processing.

The side alignment device ensures high operating accuracy by being mounted on a linear guide with two bearing carriages. Movement is driven by a servo motor.

Movable plates in the drilling area enable through milling. The parts move smoothly across the table thanks to a flow of air supplied by a special electric fan through openings in the top of the table, thereby preventing any scratches from appearing on the underside of the part.

During the machine design process, the maximum permissible loads and structural requirements were calculated and modelled. The welded frame undergoes stress-relief heat treatment to eliminate internal stresses in the material, followed by machining on high-precision CNC equipment.

The machine features rear workpiece unloading.

The sealed, dust- and moisture-resistant electrical cabinet houses electronic components from leading global manufacturers. It is located outside the machining area, extending the service life of the electrical components and providing convenient access for maintenance.
