RL 1640-A-Plus/RL-1640-A-HS Series
2-Axis CNC Teachable Precision Lathes

Outstanding Features
• Massive base is 1-piece Meehanite casting (no pedestals or sheet metal). Chip Pan is front removal so machine can be placed against a wall.
• Extra wide bed provides stability and vibration absorption, stress relieved by annealing. Induction Hardened ways to HS 70-75 and precision ground.
• Dovetail carriage and cross slide ways are Hardened & Ground then coated with Turcite-b linear anti-friction bearing material hand-scraped to ensure uniform matching surfaces.
• Headstock gears are Hardened and precision ground on Maag or Reishauer grinders for smooth, quiet, and vibration-free running.
