Automation

To increase the flexibility of the Gama 75 V 4-Axis, the machine is equipped with four automatic axes:

Electrical saw blade inclination 90° - 30°
Electrical revolving of machine table 270°
Electrical lateral movement of machine table approx. 550 mm
Electrical saw blade hight positioning 0 – 295 mm

Plus an endless measuring system with a special magnetic measuring device.

Completely protected machine base

for optimal safety and protection

Pneumatic clamping cylinders

Two vertical clamping cylinders will lock the cutting material securely on the machine table, each having a distance of 400 mm from the saw blade (saw blade position 90°)

Laser light

The laser light for cross-cutting produces a red line on the material prior to the saw blade cut.

DUO Drive units

The dual drive unit system is equipped with an in-feed-roller, out-feed-roller and special press-rollers below the material. These rollers are pneumatically connected to the rollers above.

The press-rollers work like pliers, pressing against the timber only, not the roller table. When rip-cutting different sensors control the position of the timber. The drive units are moving up and down fully automatically. The rollers have a distance of 2,250 mm (88 in.).

Cutting with maximum speed, the shortest length of the timber must be at least 2800 mm (110 in) in order to allow a complete crossing above the table.

Technical data:
Geared feed motor P2 = 1,1 kW /
feed power F = 1000 N, with infinitely variable speed settings via potentiometer 0.2–36 m/min

Drive unit extension (optional)

The DUO drive unit system can be equipped optionally with a second roller each in direction to the saw blade / machine table. The distance will be reduced to 1330 mm (52.4 in.). Cutting with maximum speed the shortest length of the timber now will be 1700 mm (66.9 in.) in order to allow a complete crossing above the table.

Aluminum back fences

Torsionally rigid aluminum profiles 120 x 120 mm are used as a back fence to the roller tables.

Measuring system, endless

Conventional measuring systems normally have a fence where the material will be pushed for measuring. The AVOLA measuring system works completely differently. Instead of a pusher system it works easily with a special measuring device (carrier). This device searches for the end of the timber on the in-feed side and drives with 2 m/sec to the end of the in-feed table. Afterwards a very small metal point is fixed into the timber and the measuring process commences.

During positioning, the measuring carrier now will be pulled at the same time the drive units are transporting the timber. Equipped with a magnetic measuring system the accuracy is 0.1 mm, independent of the total length of the measuring material. Accuracy of positioning is +/- 1 mm. The advantage of this measuring system is that the carrier is able to drive forward and backward. If the positioning length is longer than the carrier capability, the process will be interrupted, the carrier drives back and finally starts again until the end of the positioning is reached. Significantly, the in-feed roller table does not need to be as long as the workpiece.
