Requirements to matelaworking machine dramatically changed in the last decades. Following parameters have reached primary importance:

  • Functional versatility, precision and reliability;
  • Convenient and easy operation and maintenance;
  • High productivity;
  • Energy efficiency;
  • Connectivity;
  • Reasonable prices.

The new generation lathes A500 by Arinstein features all the above parameters.

Ergonomical properties of the machine are defined by the bed with the reach-over carriage; precision of travel is ensured by linear type guidelines; technological capacities of the machine are increased thanks to the turret with driven tools. The machine’s state-of-the-art CNC is suitable for solving complex technical tasks.

A 500 series is intended for high precision turning and milling of flange and roll type work-pieces, complex surfaces, e.g., knuckle pins, for tapping and threading, for milling grooves and profiles, and also for drilling holes beyond the center line of the work-piece.

Workpieces made of construction steel, alloyed and tool grades of steel, pig iron, non-ferrous and light alloys can be handled on these lathes. A 500 series are intended for manufacturing small lots and series.



Turret head of Baruffaldi, Sauter or DuplomaticEfficient power transfer through a compact design;

  • Maximum spindle speed 4000 rpm;
  • High turning accuracy.
  • CNC controls of Fanuc or Siemens

High machining accuracy;

  • 3D visualization of the machining process;
  • Network operation;
  • Use of ShopTurn software by Siemens;
  • TFT displays from 10,4″ to 17″ (Siemens / Fanuc);
  • Connectivity by LAN / WLAN / USB.

Electric cabinets are air-conditioned (Rittal) and fitted out with components by such well-known suppliers as Siemens, Baluff, Kloeckner-Mueller, etc.

Design Features

  • The bed is a welded steel construction that is filled with special sand so as to provide more rigidity against vibration and sound absorption, and also to reduce thermal deformations.
  • Moveable units are provided with linear roller-type guidelines (similar to THK) that ensure high precision of traveling and longer lifetime of the lathe.
  • Feed drives include ball screws and digital AC motors supplied by Siemens.
  • The headstock supplied by EMCO, Austria, is a cast case with ribbed surface so as to reduce thermal deformations; inside the headstock a spindle runs on high precision roll bearings.
  • Angle of the spindle is controlled by means of a special sensor.
  • The 2nd spindle (optional) is a motor spindle by Siemens, which is installed on movable carriage instead of the tailstock.
  • All the movable components are located inside the cabin so as to ensure safe operation of the machine; guidelines of the movable units are protected against chips and emulsion.
  • Thanks to the slanted position of the reach-over carriage, chips are dropped to the conveyor located in the front part of the machine.
  • The hydraulic system is integrated into one module which includes a tank with an inbuilt gear pump, an air heat exchanger, distribution, control and measuring devices.
  • The control console is equipped with TFT up to 17″, keyboard and handwheel.
  • The CNC Sinumerik 840 Dsl is compatible with the programming standards of DIN/ISO.

Specification and main parameters of the CNC
