GORATU MAQUINAS HERRAMIENTA,S.A.

GCM 4 / 5 / 6 / 8 / 10 7 JANUARY - 2011

§ The main advantages of use this element is as follows:

o Separated lubrication systems for the gearbox (oil) and the main shaft (grease).

o Avoids noise emission.

o No heat transmission from main spindle (insignificant thermal expansion for this

reason).

o No vibration transmission from gears of main spindle, and therefore machining

quality is not affected.

o High tangential forces can be withstood thanks to the robustness of the bearings

of the box output shaft.

o High efficiency degree (greater than 95%).

o Change of range through an electroiman.

10. DIGITAL FEED DRIVE OF THE X, Y AND Z AXIS

§ X axis is with double rack pinion system and electrical preload, two independent motors

and high precision planetary reducer, regulated with master-slave system.

§ Y and Z-axis have a ball screw system. The Y-axis ball screw is 50x16mm, and Z-axis

50x12mm, hardened and ground, quality ISO in accordance with DIN 69051 standard,

guided on one end with combined axial-radial bearings (drive side) and preloaded

angular contact bearings on the other end. Transmission for the movement of the Y-Z

motors to the relevant spindles is made through pulleys and belts and a transmission

relation of i=1,5.

§ The brushless servomotors are driven by regulators.
