Three terms that are well used in the feedback industry are “accuracy”, “repeatability” and “resolution”. These words are sometimes used interchangeably and should not be.

Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock-removal rate, while the power consumption during finishing is significantly lower.

In order to provide a sturdy, explosion-proof rotary encoder Leine & Linde introduces its series model 841. ATEX and IECE-x approved, this encoder is primarily meant for motor velocity feedback and positioning of heavy motor operations or generators.

Machine tools for the manufacture of large parts for the space and aeronautical industry, for construction of large turbines, or for large dies in toolmaking, all have at least one long servo axis. On these machines, axis lengths of several meters are nothing out of the ordinary.

Controlled servo drives are used in many areas of automation technology, converting, printing, handling and robotics including production machines and machine tools.

For HEIDENHAIN encoder customers who would like to do their own onsite encoder testing, HEIDENHAIN now offers the new simple-to-use PWM 20 diagnostic box with ATS (Adjusting and Testing Software).

Spindles are among the key components of a machine tool. Their characteristics are determined by the design, the drive and the bearing systems. Position feedback encoders play a decisive role particularly for the drive performance. HEIDENHAIN is presenting the NEW ERM 2400 encoders, ideal for applications that offer little space and yet require a relatively high accuracy of angular measurement.
