It presents the latest generation Gemini lathes and milling machine Lagun

Goratu has 429 square metres in Hall 13 - Stand C14 to publicize their two product lines for machining of high complexity and large in volume and weight, your milling machine Lagun and its Gemini lathes.

Goratu, specialists in the milling and turning technology, will be present at the EMO 2013 Edition. It will release its two product lines for machining of high complexity and large in volume and weight, the latest versions of its Gemini lathes and their milling machine Lagun. It will be located in Hall 13, stand C14 and have 429 square metres. Milling machine Lagun range will be represented by the model GCM, column milling machine mobile on fixed and mobile upright cross GTM milling machine.

This type of machine allows machining of large length, up to 12 meters, without causing virtually limitations by the weight of the piece to be all carro-columna that performs longitudinal displacement.

It allows pendular work, i.e., you can have two separate and protected independently working areas. This facilitates the machine to work in an area while the operator performs the work of preparing the next piece in the other area.

Main technical characteristics:

• Displacement of 6000 X: and Y: 1200 z 1500
• Complete equipment of:
  • Double panel control Heidenhain iTNC 530 HSCI
  • Wireless steering wheel with display Heidenhain HR 550 FS
  • Automatic universal head in two bodies each 2.5 ° cooled EGR oil and turn 6,000 rpm continuous capacity,
  • Internal coolant through the tool of high pressure
  • Chip extractors
  • 40 HTA warehouse. change in vertical and horizontal type chain
  • Machine for pendulous work with two areas of work

This product line allows machining of large volume and weight with high requirements of accuracy, in an environment of difficult access and multiple surfaces and planes to be machined. The arrangement of the axes that make up the machine allows you to adjust optimally machining at the point of machining accuracies. It is set several movements of relatively short courses so combining these shifts keep the qualities of precision and also allow handling of parts mostly high volume but also medium to high load.

Main technical characteristics:

• Displacement of 3000 X:, Y: 1200, z 1500 v 1000
• Plate C: continuous rotation of 1800 x 1800 with carrying capacity of up to 10 tons
• Complete equipment of:
  • Control Heidenhain iTNC 530 HSCI
  • Automatic universal head in the two bodies each 2.5 ° cooled oil recirculation and capable of turning at 6,000 rpm in continuous
  • Internal coolant through the tool of high pressure,
  • Chip extractors
  • 60 Tool magazine. change in vertical and horizontal type chain
  • Probe centering, alignment and testing of Renishaw RMP 60 piece

Both Millers have revolutionary head GHS designed and manufactured in Goratu getting 6,000 rpm keep the temperature stable through a cooling system by oil recirculation. This system allows to measure lubrication, in such a way that the oil flow management adapts to the speed. All rotating parts are permanently lubricated, which reduces friction and wear to increase service life and precision in long periods. This lubrication system requires no maintenance.

Main technical characteristics:

• Turning at 6,000 rpm continuous speed
• High thermal stability
• Long life
• High precision
• Power 28\1kW\2en S1
• ZF refrigerated box

Universal head refrigerated at 6,000 rpm.

The range of lathes Gemini will be represented by a horizontal models GT7 and GHT9.

Completing the range of light heavyweight lathes, Goratu has joined its catalogue the new Gemini GT7 model architecture of 4 guides. The base has been redesigned extending the width between guides to 1,250 mm and increased camber for chips. This innovation enables an optimal index for the disposal of chips.

GT7 G4 main technical characteristics:

• Capabilities

1. Diameter over bed 1.600 mm
2. Over cross slide diameter 1300 mm
3. Distance between points 5 m

• Head

1. The main shaft hole diameter 162 mm
2. The main shaft DIN 55026-15 nose
3. Diameter of front bearing shaft 240 mm
4. Speeds (4 ranges) 0-800 min - 1
5. Maximum torque Nm 13.750
6. Main engine 51 kW

• Counterpoint

1. 220 Mm shank diameter
2. 300 Mm shank course

• Bench guides 1,250 mm width
• Weight of workpiece between points 12,000 kg

The four guides model presented at the EMO exhibition carries as main novelty a special head with so-called dual-motor head Twin Drive. The double engine allows to eliminate gaps, reducing noise and vibration in operations of turning and a better positioning accuracy.

Other accessories include the zero point clamping system. This system allows the mooring and unmooring automatic different devices such as grinding and the bar of boring instead of the turret.

Like main novelty, the exposed GTH9 Geminis in EMO 2013 incorporates a special head with so-called dual-motor head Twin Drive.

Another of the peculiarities of this machine is the dimension of the fairing. The front door has a width of 2 metres for greater protection of the operator.

GHT9 G4 main technical characteristics:

• Capabilities

1. Diameter over bed 2,100 mm
2. Diameter over cross slide 1.820 mm
3. Distance between points 5 m

• Head

1. The main shaft hole diameter 150 mm
2. The main shaft DIN 55026-15 nose
3. Diameter of front bearing shaft 320 mm
4. Speeds (2 ranges) 0-550 min - 1
5. 30,000 Nm maximum torque
6. Main engine 90 kW

• Counterpoint

1. Diameter of 320 mm shank
2. 250 Mm shank course

• Bench guides 1,300 mm width
• Weight of workpiece between points 25,000 kg
