The GL.3/5 is a 5-axis production machine designed for laser micromachining applications, according to developer GFH GmbH, Deggendorf, Germany.

Gantry-style construction minimizes errors accumulated by interaction of the machine’s linear axes and provides very good stiffness and beam pointing stability under all conditions, the company said. Long-term static and dynamic rigidity are assured by granite construction of both the machine base and X- and Y-axis carriages. The granite construction also provides good temperature stability and excellent vibration attenuation.

The GL.3/5 is a five-axis machine for complex laser micromachining applications.

Active cooling of linear drives, the control cabinet and other heat sources using a water/water cooling device further improves accuracy even during operation under full load. The result is accuracy of ±1µm in X and Y and ±2µm in Z, with repeatability of ±0.5µm in X and Y and ±1µm in Z. The machine’s A-axis, which has a range of motion of ±110 degrees, has accuracy and repeatability of 5 and 2 arc-sec, respectively; while the continuous-motion C-axis features accuracy and repeatability of 3 and 1 arc-sec.

Linear axis travels (X-Y-Z) are 640mm, 445mm and 360mm. Maximum acceleration on linear axes is 20 m/sec2, while maximum speed is 120 m/min in X and Y and 60 m/min in Z.

The machine can be equipped with a variety of laser sources to handle a range of micromachining applications. The beam is guided in a pressurized and encapsulated beam path by beam deflection units. The company also provides contract laser micromachining services.
