SE520 SL NUMERIC

Kategórie: 

CNC universal center lathe is designed on the basis of SE520 Numeric. Thanks to the new bed, the distance between centers was enlarged to 2000  mm. The fully covered working space allows to increase technological possibilities of long work-piece machining. The machine can turn simple, as well as complex shapes work-pieces. The machine can be customized in various optional executions and it can be equipped with various optional accessories. SE520 SL works as a universal lathe in a manual mode, being controlled by the hand wheels or in the full CNC control to perform demanding technological operations. This enables new machining possibilities for piece production and increase the productivity of small series production.
 
MAIN FEATURES

  • Ideal machine for a user switching from universal lathe to CNC controlled machine
  • Easy and comfortable control through large touch screen
  • Long lifetime with focus on keeping high machining accuracy
  • Spindle drive through belts  - minimization of vibrations during machining
  • Automatic gear shifting during the working cycle
  • Bearings with lifetime grease filling – low operating costs
  • Fully covered working space – high stage of operator’s safety, the prevention of flying chips and coolant leaking, allows increased coolant pressure and cutting speed - increase in machining productivity
  • Wide scope of executions and accessories – hydraulic clamping, hydraulic tailstock control, hydraulic and manual controlled self-centering rests in various executions, boring bar holder, live tools, wide scope of face plates.
  • Intuitive and user friendly software machine control

 

CHARACTERISTIC FEATURES:

Apron guideways with layer of friction substance  – reaching positional accuracy even at minimal feed Preloaded ground ball screws – high dimensional accuracy of workpieces Machine geometry measuring by laser device – exact setting of machine axis parameters
Variability of selection of optional turrets Constant cutting speed – high quality of turned surfaces Variety of control systems

 

These machines combine advantages of conventional and CNC lathes. The machine works as a conventional lathe, in manual mode, being controlled by the hand wheels. If required, the operation mode can be shifted to the full CNC control. Technological operations of machining can be programmed by simple filling-in the pre-defined cycles or eventually by standard programming. Machines are therefore suitable for piece and small-series production of simple as well as complex shapes of the workpieces from metal and plastic. Geometric accuracy of the machines fulfills norms  ISO 1708 and ISO 230-1.

MAIN ADVANTAGES:

  • Ideal machine for a user switching from conventional to CNC controlled lathe
  • Easy operation
  • Manual, cycle and automatic mode
  • Software support for contour programming as well as DIN programming
  • Axis positioning through servomotors
  • Control system options - SIEMENS, FANUC, HEIDENHAIN
  • Option of 8-positional turret with/without live tools
  • Wide scope of executions and accessories – hydraulic clampings, chip conveyors, drilling bar holders, steady and follow rests, faceplates and chucks, hydraulic tailstock
