(CNC) Live-Tool Lathes

A-Turn 375 • 450 • 500

The A-Turn series from KAAST is a powerful CNC lathe that features a one piece Meehanite slant bed with a low center of gravity and superior rigidity. The flex-resistant and shock-absorbing headstock is heat-treated and annealed twice. Reaching HRC53 hardness, it can take heavy cuts while maintaining accuracy. The heavy-duty spindle is supported in three separate places: between two roller bearings and an angular ball bearing, ensuring maximum stability. The A-Turn series also offers the option of live tooling, up to 11 kW (15 Hp), for the 375 model, the 450 model, and the 500 model.
