When purchasing a vertical machining center, how do you trade off linear guides versus box ways in terms of accuracy retention and maintenance cost?
• Linear guides reach 48m/min+ for high-speed light cuts but have lower vibration damping than box ways.
• Box ways offer large contact area and damping for heavy cutting and mold work but need periodic scraping.
• Linear guide accuracy depends on block preload and lubrication; check preload every 2000km.
• Box way wear requires manual scraping with high repair cost; linear guide block replacement is faster and cheaper.
• Choose box ways for heavy steel cutting, linear guides for high-speed aluminum batch production.
