Universal Center Lathes

SUI80 is a lathe characterized by tough construction and highly rigid bed which allows its use for most challenging turning operations in piece and small-lot production. Thanks to its versatility it is suitable for maintenance and repair divisions as well.

Most important features:

  • High output at high cutting force
  • Easy maintenance
  • Long lifetime
  • Low operating costs
  • Easy and ergonomic control
  • High turning precision
  • Various versions with wide range of optional accessories
  • Turning length up to 8 meters

 

CHARACTERISTIC FEATURES:

Important parts of the machine are made of grey cast iron – minimization of generating vibrations throughout machining Hardened bed guide ways – long lifetime and constant accuracy of machining Hand scrapping of the important parts – high precision during machining
Bed gap for increasing the swing and delta-shape bed – high resistance against deformation and continuous chip conveyance Spindle drive through clutches and brake – smooth movement stop Single lever for four way control of feeds with adjustable feed clutches

 

Machines of outstanding performance designed for piece and small-lot production suitable also for maintenance and repair divisions. TRENS lathes are precise and reliable machines in wide range of versions and optional accessories.

MAIN ADVANTAGES:
