When purchasing a machining center, how do ball screw accuracy grade (C3/C5) and lead affect positioning accuracy?

• C3 ball screw error ≤8μm per 300mm travel; C5 ≤18μm.
• Positioning accuracy depends on screw grade plus linear scale feedback; closed loop compensates.
• Small lead (e.g. 10mm) gives higher resolution; large lead (20mm) gives faster rapid.
• Choose double-nut preload to eliminate backlash.
