Description

SE520 Numeric Basic is an universal CNC lathe with digital drives and cycle control for machining flanged and shaft parts with the possibility of manual control, which finds application mainly in small and medium series production of smaller parts and is also suitable for piece production operations. It is possible to machine simple but also very complex flanged and shaft workpieces made of metal and plastic on the machine.

It is also suitable as a teaching tool for high schools and universities. It is possible to turn on the machine in manual control mode using electronic wheels or, thanks to a modern control system, to perform technological operations in automatic mode or using predefined cycles. This opens up new possibilities in piece production and increases productivity when machining small series.
 

Main characteristic features:

  • Ideal machine for a user switching from universal lathe to CNC controlled machine
  • Easy and comfortable control
  • Long lifetime with focus on keeping high machining accuracy
  • Spindle drive through belts – minimization of vibration level that could negatively influence turning
  • Automatic gear shifting during the working cycle
  • Bearings with lifetime grease fi lling – low operating costs
  • Annealed machine components for internal stress removal – high accuracy and stability throughout lifetime of the machine
  • Covers with reinforced zones – high level of operator´s safety
  • Machining by built-in cycles (by filling-in parameters)
  • Final grinding of guideways performed only after full bed assembly for maximum accuracy
  • Bed guideways hardened to 400HB min. depth 2mm
  • Positioning accuracy of every single machine is checked by laser measuring device
  • Heat-treated spindle with hardened surface
  • Wide scope of executions and accessories – hydraulic clamping, hydraulic tailstock control, live tools, wide range of steadies and faceplates
  • Bearings with lifetime grease - low operating costs

Characteristic features

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.

  • 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 tool posts
  • Constant cutting speed – high quality of turned surfaces
  • Variety of control systems

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
