THROUGH-FEED CNC MACHINE KDT KN-612 NCHSD

KDT KN-612 NCHSD is an extremely productive through-feed machine designed for drilling, milling, and sawing. It features three independent drilling units that allow simultaneous machining of two workpieces, ensuring high productivity. Two drilling heads are positioned on the top and one on the bottom. The advantage of this machine is side drilling using two upper aggregates. The bottom drilling aggregate is compactly designed to take up minimal space, meaning the worktable opening is smaller and the workpiece gains more support during drilling, resulting in greater stability and machining precision.

The machine features a built-in grooving saw Ø120 mm designed for creating grooves for cabinet back panels.

An AI interface, larger drilling unit, and fixed angular head with four outlets provide advanced, precise, and powerful machining for better machine efficiency and shorter production times.

The KN-612 NCHSD is also equipped with four independent milling aggregates for grooving and cutting on all six sides. A new feature is the 6 kW milling motor with a fixed angular head and four outlets for side grooves on all four sides. An additional bottom fixed milling aggregate features a manual tool changer, meaning the machine includes two lower milling units for two different grooving tools. The main upper milling aggregate (5.5 kW) includes an automatic tool changer with six positions.

Machine operation is simple thanks to the industrial computer (Windows) and KDT DrillTop software. The machine is equipped with a barcode reader for barcode-based operation. It supports ONLINE service via TeamViewer, and programs can be created both on the machine and in the office. The package also includes a one-year LestrojBOX license for automatic furniture generation.

Double-sided independent clamps enable faster and more precise work. The clamp guide length of 5500 mm allows processing of long pieces without re-clamping. The air-floating infeed table makes it easier to move workpieces with delicate surfaces, while the cross transport system ejects the processed workpiece from the machine. The conveyor belt removes waste material.

The machine is easy to use, requires no mechanical adjustments, and thanks to the barcode system, no experienced operator is required.

	1. Drilling unit arrangement Top vertical drill 26V + horizontal drill 16H + bottom vertical drill 9V. The upper and lower drilling packs work in coordination, covering a wide area, optimizing drilling, and improving efficiency.
	2. Spindle arrangement Top: 6 kW side milling motor providing greater power and efficiency for lateral milling. The unit is independently mounted for easy tool installation, maintenance, and servicing and can be equipped with a single- or four-sided aggregate. Bottom: dual spindle 3.5 kW × 2, which can be equipped with grooving or straight cutters, ensuring higher machining precision.
	3. Dual-layer spindle with 6-position automatic tool changer (ATC) Two layers with six positions each allow the use of tools with different specifications. It is possible to store horizontal blades for rough and laminated processing. The system allows automatic tool length adjustment and detection.
	4. Positioning rod with three bearings Enables precise positioning of smaller panels without damage during clamp change.
	5. Dual positioning device Allows selection between two positioning modes depending on panel size.
	6. Floating clamps with automatic cleaning function A 5.5 m guide enables clamp movement speed up to 140 m/min, effectively removing dust from the board surface.
	7. Dual translational air table (patented) A floating platform with multiple work sections allows smarter avoidance and optimal support during processing.
	8. Air pressure plate (patented) Covers a large surface area, ensures minimal vibration during machining and high precision, while also protecting the panel from scratches.
	9. New control system Predictive drilling with an intelligent AI algorithm plans the optimal path, while the drilling bar works in advance, increasing efficiency by 15%.
	10. Scanner (standard with handheld gun) Allows scanning of labels and recognition of work files.
	11. Machining processes Supports various processes and significantly improves production efficiency.
