💡 What makes a precision steel linear guide maintain alignment longer than standard bushings?
- Thick carbon steel resists flex so your cuts stay square during aggressive feed rates
- Chrome coating creates a slick track that shrinks drag when you change direction fast
- Graphite sleeves shed dust and keep clearances tight without greasy buildup ruining tolerances
