2/3/4/5 Axis Digital Readout DRO TTL Linear Glass Scale Encoder CNC Milling Lathe1. ApplicationLinear scales are ideal for machines and other equipment whose feed axes are in a closed loop, such as milling machines, machining centres, boring machines, EDM, lathes and grinding machines. The beneficial dynamic behaviour of the linear encoders, their highly reliable traversing speed, and their acceleration in the direction of measurement make them ideal for use on highly-dynamic conventional axes as well as on direct drives.
2.Benefits of linear scales| Reduction of mechanical errors | linear scales directly measure the position of the moving element and consequently reduce or eliminate errors caused by ball screw thermal expansion, hysteresis, and pitch errors. |
| Well defined thermal behaviour | linear scales have defined coefficients of thermal expansion making it possible to select the linear encoder whose thermal behaviour is best suited to the application |
| Excellent dynamic behaviour | Linear encoders are characterised by their high rigidity in the measuring direction. This is a very important prerequisite for high-quality path accuracies on a machine tool. In addition, the low mass of components moved contributes to their excellent dynamic behaviour. |
