COMPACT AND VERSATILE SYSTEM FOR MACHINE-TOOLS
Because of its "reduced siza", it is particulary suggested for small Machine-tools or for applications with limited installation space. Futhermore, the possibility of registration simplifies the alignment and makes use on rough surfaces easy (retrofitting and Machines for which application was not foreseen).
Optical Scales are Givi Misure's basic product. They are made in four different models, for each of which there are a number of variants. The documentation, supplied on request, stresses the high performance of these products.
- Dovetail for fixing whith sliding block.
- Grating in stainless steel. Size mm 15 x 0.203 in a single piece.
- Scale housing in anodized extruded aluminium TA 16. Size mm 23 x 18. Section mm² 141 - Weight Kg/m 0.380.
- Lip seals in elastomeric 70 for the internal protection of grating (two lips). The protections, inserted in their grooves, are easy to change.
- Slider set composed by : Die-cast tie rod (T) with water proof housing of electronic circuitry, internal connector and cable clamp. The lining is facilitated by three dowels. Plastic molded reader head (P) with metal insert. Flexible coupling for compensation of disalignment and mechanical hysteresis errors (max. residual 2µm).
- Wings to prevent the outlet of slider from its seat. Mechanical limit of mounting tolerances.
- Linear O-Ring for holding the grating in the seat. Its elasticity allows the free expantions of the grating without deformation in case of installation faults.
- Expansion block for intermediate fixing of the scale, positionable along the run.
- End blocks for lateral fixing of the scale. The slots and the four dowels facilitate the alignment according to the mounting tolerances . The hooking system of the bearing (anchor guided by pivots), locks the lip seals in order to avoid shrinkage.
- Rubber gaskets for scale ends, to reinstate in case of disassembling of the end caps.
