For heavy cutting conditions, should a CNC lathe use linear guides or box ways? What are the selection criteria?
• Box ways offer high damping, ideal for heavy and interrupted cutting.
• Linear guides have low friction and high rapid speed, suited to finishing and light loads.
• Judge by cutting force: depth of cut >5mm or cast iron favors box ways.
• Box ways require scraping; contact ratio shall be ≥75%.
