Nanometer High Resolution Linear Encoders
January 1, 2015
Fagor Automation Corporation has developed a line of linear encoders capable of nanometer resolution. "Designed for high performance markets such as precision grinders and the EDM market, the new product has the capability of achieving nanometric measurements directly from the encoder without the need for electronic interpolation. The encoders provide improved position and speed control, resulting in a superior surface finish of the manufactured parts and smoother machine axes positioning for added machine life. The nanometer encoders are designed for high speed linear motors, improving performance in terms of positioning accuracy, repeatability and smoothness due to the acute encoder resolution," said a company spokesperson.
The linear encoders are available in G, S and SV series extrusion platforms. The G series is a full sized robust extrusion designed to withstand harsh environments. The S and SV series utilize a more compact extrusion allowing for proper fitment within applications with limited space.
According to the company, the G and SV series encoders incorporate the patented TDMS (Thermal Determined Mounting System) designed to allow for minimum error deflection regardless of the environment by controlling the expansion and contraction of the scale. "The positioning errors originating from machine mechanics are minimized as the encoder is directly mounted to the machine surface and the guide ways. The encoder sends the real machine movement positional data to the CNC, therefore, mechanical errors due to thermal behavior, pitch error compensation and machine backlash are minimized," said the spokesperson.
Nanometer resolution encoders are available in travels up to 3 meters and are subjected to an extensive final accuracy check. According to the company, this control test is carried out on a computerized measuring machine equipped with a laser interferometer located inside a climate-controlled chamber. The printed result of each individual test is supplied with every Fagor encoder, allowing Fagor Automation to guarantee accuracy on every linear encoder.
