Manual Engine Lathes
Conventional manual engine lathes built with precision and designed for maximum accuracy, performance, and reliability.
The C-Turn 220 - 750 is our conventional manual engine lathes, in a manual configuration. It is our aim to offer the best and most precise lathes possible for 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.
C-Turn Series Features
The C-Turn series Manual Engine Lathes feature hardened, precision-ground guideways, exceptionally low noise, and a universal gearbox. This allows for cutting metric, Whitworth, module, and diametral threads down to the most precise measurements 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 Manual Engine Lathes are 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 conventional engine lathe is carefully designed for maximum stability when performing heavy precision cutting. It's massive bed is a box type construction combined with extra wide bed ways, providing increased rigidity and stability. Manufactured from high quality cast iron, the bed and stand are 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.
