Aerospace standards cast aluminum beam,high accuracy, good toughness, light weight, corrosion resistance, anti-oxidation, low density, and greatly increase the processing speed.

Double-rack, double-driver;rack, guide and motor drive all use the international first-line brand, and use laser interferometer to test to ensure cutting accuracy; use the milling cutter to process the ruler more than 5 times to ensure the accuracy of the ruler, the middle of the guide rail and the ruler An adjustment block is installed for adjustment of accuracy.
