Linear Slide Rails in 7-Axis Aerospace Machining: Sub-Micron Repeatability Over 4-Metre Spans

Material & hardness architectureStandard 1060 carbon steel would yield under 30 kN peak inertial loads; instead, 42CrMo4 (AISI 4140) is induction-hardened to 58–62 HRC to a depth of 2 mm, then hard-turned to h6 tolerance and chrome-plated to 15 µm. This yields a surface roughness Ra ≤ 0.2 µm and a case depth sufficient for 50 000 km of rolling contact. For vacuum or...
