The 2020 Ringtech RTL-4000 4-Axis CNC Mill/Turning Lathe represents the pinnacle of micro-turning innovation, engineered for high-precision applications such as watch, jewelry, and medical device manufacturing. This machine features a 42000 RPM HSK-25E live spindle, Y-axis milling, 42 mm barfeed assembly, and an advanced probing system for real-time tool and part verification. The layout supports efficient chip evacuation through an angled pan and separator tank, while the 16C-adaptable spindle enhances chucking flexibility. Designed around Swiss-style high-performance turning architecture, this lathe brings advanced cutting performance in an ultra-compact envelope. Compared to simpler 2-axis turning systems, the RTL-4000 stands apart with its integrated 4-axis functionality and 42000 RPM live tooling, offering a dramatic leap in speed, control, and surface quality. Lesser systems in this class may lack simultaneous Y-axis milling or high-speed probing, both of which are standard here for tight-tolerance, high-mix production.
