Purpose

The KDT KD-812A CNC through drilling center with six drilling, four milling and two grooving groups on two independent tables is designed for high-speed processing of workpieces from six sides in the through mode, which allows increasing the processing efficiency. The machine is used for serial production.

Two work tables

Scheme of drilling groups

Work as part of a drilling line

Distinctive features

Design advantages

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

CAD/CAM control panel, with the ability to read bar codes, which allows you to increase the productivity of the machine.

Barcode scanner on every desktop.

Each working table has 3 drilling groups : 12 - horizontal spindles, 35 - vertical spindle (26 - top, 9 - bottom) and 2 milling units - 1 top (5.5 kW) + 1 bottom (3.5 kW) + top grooving units with a saw (disk diameter 120 mm).

In total, 4 milling spindles, two grooving units and 6 drilling groups are installed on two tables for: 94 drilling spindles (70 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.

2 grooving units with a saw (disk diameter 120 mm).

The machine bed was developed taking into account CAD programs, where the maximum allowable loads and requirements for the machine design were calculated and simulated. The welded frame is tempered to relieve all internal stresses in the material, then processing takes place on a five-axis metalworking machine, where all platforms and holes for mounting components and assemblies are milled.

Mobile plates in the drilling area allow for through milling.

Easy movement of parts on the table occurs due to the air flow supplied by a special electric fan through the holes in the upper part of the table, thereby eliminating the possible appearance of scratches on the lower surface of the part.

Two automatic clamps allow you to securely hold workpieces from 250 mm to 2800 mm long and perform fewer interceptions during drilling, which significantly increases the speed of the work cycle compared to machines with a single grip. Clamps operate at speeds up to 140 m/min .

The machine carries out automatic alignment and positioning of the workpiece.

Automatic part width detection using a sensor.

The machine has rear unloading of parts.

The minimum workpiece size is 250x50 mm , which allows for the addition of small-sized parts.

Sealed dust and moisture resistant cabinet with electronic components from the world's leading manufacturers is removed from the processing area, which prolongs the service life of electrical components and provides ease of maintenance.
