SE820 NUMERIC

Kategórie: 

SE820 NUMERIC is a machine from category CNC universal center lathe designed for turning large rotational workpieces. It allows for turning outer and inner cylindrical, conical and complex shapes and all kinds of threads as well. In combination with drilling and milling it allows machining of complex shapes from bars, forgings and split material. Wide variability in specific turning operations for gas, oil and water industries.

Most important features: 

  • Ideal machine for a user switching from conventional to CNC controlled machine
  • Easy and comfortable control
  • Long lifetime with focus on keeping high machining accuracy
  • Headstock with 2 speed gearbox – possibility of big diameter workpiece turning
  • Automatic gear shifting during the working cycle
  • Bearings with lifetime grease filling – low operating costs
  • Direct spindle position measurement-high accuracy in out-of-axis machining at big diameters
  • Annealed machine components for internal stress removal – high accuracy and stability throughout lifetime of the machine
  • Machine covers with reinforced areas – high level of operator protection
  • Wide selection of optional executions and accessories – hydraulic clamping, hydraulic tailstock control, turret with live tools, C-axis with servomotor, options for enlarged distances between centers, steady rests and faceplates

 

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
