Okuma’s SPACETURN LB EX II series CNC lathes are built to the high performance standards set by the successful LB series product. With new models and 66 option variations offering high accuracy with enhanced multitasking capacity, the LB EX II series is the flagship 2-axis lathe in the Okuma line-up. Built on a high quality box slant bed and a thoroughly tested thermal design, the LB EX II series is able to achieve machining dimensional change over time of less than Ø5µm. And with a ball-screw driven tailstock along with X and Z rapid traverse rates of 25 and 30m/min respectively, the machines were created with accuracy and flexibility in mind.
