Engineering advantages

Drilling from 6 sides. There are 2 drilling groups installed on the machine: 10 - horizontal spindles, 22 - vertical spindles (13 - from above, 9 - from below). As standard, there are 2 upper milling units for 9 kW and 5.5 kW and two lower ones for 3.5 kW each .

The upper drilling and milling group consists of 10 horizontal spindles and 13 vertical spindles and 2 milling spindles for 9 kW (possibility of milling in the C axis) and 5.5 kW . The upper milling spindle, due to its increased power, has the ability to work with various tools and carry out various operations - milling under the LAMELLO tie, milling at 45 °, milling for door fittings, side milling and grooving.

The support of the multi-functional rotary axis C by the upper left milling spindle makes it possible to work with many types of machines. The 360° C-axis eliminates repositioning by the machine, so the part can be machined in one cycle. A magazine for 2 units speeds up the processing process. And the clamp with an air cushion enables high-quality processing of the part.

The upper right milling spindle is equipped with a 10-position linear tool change , which saves time when switching from one type of processing to another and makes it possible to work in automatic mode thanks to a tool length measurement sensor.

The left milling spindle is equipped with a 2-unit tool change, which saves time and makes it possible to use a wide range of aggregates.

The lower drilling and milling group consists of 9 vertical spindles and 2 milling spindles of 3.5 kW each.

Two automatic clamps will allow you to securely fix the workpiece with a length of 70 mm. up to 2800 mm and perform fewer interceptions during drilling, which significantly increases the speed of the work cycle compared to machines with a single grip. The maximum speed has been increased to 140 m/min .

The top milling spindle is equipped with a powerful vertical clamp with two pressure plates . Improves milling accuracy and prevents damage to the workpiece.

Batch drilling mode - processing of two parts at the same time with a drilling map.

Tool length sensor minimizes time for calibration and tool change.

CAD/CAM control panel with barcode reading capability to increase machine productivity.

A barcode scanner is included in the basic equipment of the machine.

Ability to work with all popular programs for optimizing additive maps.

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 bed 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.

The machine in the basic configuration has a conveyor for removing chips and small residues of workpieces.

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.

Mobile plates in the drilling area allow for through milling.

Protecting the operator from injury.

Finished parts exit area with cross conveyor, equipped with workpiece detection sensor.

The minimum workpiece size is 70x35 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.
