 Aplication Sample



Semiconductor and LCD production equipment is required high speed, accuracy and low particle emission, because even the tiniest piece of extraneous substance can cause major faults in the final product. Thanks to their original configuration, LM guides create minimal particles because there is little metal-on-metal contact. As such, they have become crucial the components of semiconductor and LCD
