KAAST lathes meet the highest quality standards

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.

Optimal Structure Design

  • Wide bed and box constructed, bed ways are high frequency heat treated, precision ground which can avoid vibration and tool chattering during performing heavy duty machining
  • 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 entire structure is carefully designed for maximum stability when performing heavy cutting

Optional with extra large spindle hole

Up to 4”, 6”, 9” and 12” spindle diameter
