ROSA ERMANDO will exhibit two machines with the very latest Digital Linear Motor technology - on the X axis, the Linea R46 and STEEL Linear 11.7 CNC.
Digital Linear Motor technology has the benefit of considerable time reduction for table reversals by ensuring higher table speeds (up to 60m/mm). During plunge and reciprocating grinding the over-travel and the time for table reversal is reduced, independent of the work-piece length, enabling grinding times to be reduced by up to 40%, whilst still preserving the same quality of finished product.
Table positioning within a micron, which may be necessary when grinding slots or pockets in die and mold components.
Very slow table motion, even at a few millimetres per minute, which is typical for creep-feed grinding.
Interpolation of table motion with vertical motion of the grinding wheel, thus allowing geometry and accuracy levels which a few years ago were inconceivable.
Linea R46 for interpolation and creep feed grinding, with the latest Digital Linear Motor on the X axis, travelling column design, high performance wheel drive 7.5 – 25kW, 1,500 – 6,000 rpm., HSK clamping system, sophisticated yet easy to use CNC control. Automatic grinding cycles for flat surfaces, profiles, multilevel surfaces, slots and shoulders – grinding has never been so simple! Grinding area 650x450 mm.
STEEL Linear 11.7 CNC with the very latest Digital Linear Motor technology on the X axis, for interpolation and creep feed grinding, carrying out concave (hollow) and convex (camber) profile grinding in both cross and longitudinal directions. Grinding area: 1,000 x 650 mm

Grinding machine for surfaces and profiles, model STEEL LINEARfrom ROSA ERMANDO S.p.A.
The new Grinding machine STEEL LINEAR from ROSA ERMANDO S.p.A. allows both reciprocating grinding and creep-feed grinding (full cut) carrying out concave (hollow) and convex (camber) profile grinding both in cross and longitudinal direction. The movement of the table is obtained by a digital linear motor. This permits a considerable reduction of the time for reversing the table motion by ensuring a higher speed of the table (up to 60 m/min). During plunge grinding and reciprocating grinding, the overtravel and the time for table reverse will be reduced. In this manner, independently from the work length, the grinding times are up to 40% shorter. The cooling by fluid of the linear motor separates thermally the motor from the machine frame, thus offering positive effects on the thermal behaviour and thermal stability. Also the geometrical precision of the workpieces is ensured by a direct linear drive, so that components subject to wear (ball-screws, belts, couplings or cylinders) are no longer required. The machine can be equipped with additional devices such as lateral grinding heads and dividing apparatuses so to grind complex workpiece shapes which before required several set-up steps. Thus the work-in-process operation can be avoided, and the output capacity of the machine can be increased. This grinding machine may be used both for small and for large series as well as for single parts, where the complete grinding job can be carried out on the machine unmanned. CNC unit mod. E.C.S. 2400D - ROSA SYSTEM V: CNC specially designed for grinding machines, having 6 controlled axes, integrated PLC, high-resolution 14” colour screen, integrated CAD-CAM system for creating profiles, dynamic simulation of the work and optimisation of the tool path. Programming of the machine is very simple and is facilitated by the use of interactive windows. Therefore also a traditional operator can easily use this kind of CNC grinding machine. The cross axis and the vertical axis are driven by ball-screws and have double preloaded screw nuts. The drive is obtained by brushless A.C. motors and is controlled by encoders or, on request, by optical scales with resolution of one micron. The spindle unit is an interchangeable cartridge type and runs in preloaded opposite contact bearings of the precision type. The spindle housing is made of special cast-iron having a low thermal expansion factor. The spindle is coupled by means of a motor cooled by a liquid medium. The spindle motor as standard has 22 kW (options up to 30 kW available). Grindable cube size: 1500x750x600 mm.
