Fagor Automation Corporation has developed and introduced a new line of Linear Encoders capable of 50 nanometer resolution. Designed for high performance markets such as precision grinders and the EDM market. In addition, due to the ability of the new product capability of achieving nanometric measurements directly from the encoder without the need for electronic interpolation, the encoders are an excellent Metrology solution as well. The new Encoders provide improved position and speed control that results in a superior surface finish of the manufactured parts and considerably improved smoother Machine axes positioning for added machine life. In addition, these new nanometer encoders have proven to be an excellent solution for high speed linear motors by improving the motors performance in terms of positioning accuracy and repeatability and smoothness due to the acute encoder resolution.
The new line of linear encoders are available in the well proven G, S and SV series extrusion platforms. The G series is a full sized robust extrusion capable of withstanding even the harshest of environments. The S & SV series utilize a more compact extrusion allowing for proper fitment within applications with limited space.
It should be mentioned, the G and SV series Encoders incorporate the Patented TDMS® (Thermal Determined Mounting System) that allows 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.
Nanometer Resolution Encoders are available in travels up to 3 Meters and are subjected to an extensive final accuracy check. 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. This allows Fagor Automation to guarantee accuracy on each and every Linear Encoder sold.
This new product offering expands an already broad spectrum of Fagor Encoder products which includes a large variety of Linear, Rotary & Angular encoders available in a selectable range of resolutions and accuracy as well as a multitude of protocols including Absolute and Incremental. In addition, Fagor Encoders are compatible with most CNC manufacturer’s protocols.
