C-Turn

C-Turn Series (Manual) Engine Lathes

C-Turn 178 • 230 • 270 • 315 • 385 • 420 • 530

    It is our aim to offer the best possible lathes to our customers. In order to fulfill this promise, we ourselves have set the very highest demands and apply strict quality control during the entire manufacturing process. Before delivery, each machine is subjected to intensive inspections and tests with regard to accuracy, performance, and reliability. The C-Turn series from KAAST features hardened, precision-ground guideways, exceptionally low noise, and a universal gearbox, allowing for cutting metric, Whitworth, module, and diametral threads with no need to change gears. The feed handwheel can be ordered left or right based on the needs of the operator and rapid traverse, standard on 385 & 420 models, can be added as an option to smaller sizes. The C-Turn series is also available with stepless spindle speed and constant Surface Speed (CSS) feature up to 3,100 rpm. Offering an optimal structure design, the entire structure of the C-Turn series lathe is carefully designed for maximum stability when performing heavy cutting. The massive bed is a box type construction combined with extra wide bed ways, providing increased rigidity and stability. The bed and stand are manufactured from high quality cast iron and annealed to relieve internal residual stress. The bed ways are high frequency heat treated and precision ground which can avoid vibration and tool chattering during performing heavy duty machining.
