PURPOSE

The KDT KD-868HA 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.

CHARACTERISTICS

  • Productivity 6 blanks / minute;
  • High processing speed: 140/90/50 m/min;
  • 2 independent desktops;
  • Drilling from 6 sides;
  • 3 drilling groups (2 top + 1 bottom) on each table;
  • Two milling units (1 top + 1 bottom) on each work table;
  • Grooving unit on top on each work table with a 120x20x4 mm saw;
  • Additive of small parts from 250x50 mm;
  • Work of the machine in the through mode;
  • Automatic detection of part width by sensor;
  • Automatic positioning of the workpiece by aligners;
  • Visualization of the processing of a double-sided additive map;
  • Scanner for reading the additive card by barcode on each table.

DESIGN ADVANTAGES

Independent processing of two panels
processing on two tables

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

Control Panel

Each working table has 3 drilling groups: 12 - horizontal spindles, 35 - vertical spindle (26 - top, 9 - bottom), 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).

Drilling from 6 sides

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.

Milling unit

During the development of the machine, the maximum allowable loads and requirements for the design of the machine were calculated and modeled. The welded frame is tempered to relieve all internal stresses in the material, then it is processed on high-precision CNC equipment.

Discharge conveyor

The machine has rear unloading of parts.

Positioning clamps
Positioning clamps

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.

Mobile stoves
Mobile stoves

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.

Workpiece positioning
Leveler

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

Auto-detection of workpiece width
workpiece size determination

Automatic part width detection using a sensor.

Minimum workpiece size
Minimum workpiece size

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

Electrical cabinet
