HEIDENHAIN ITALIANA Srl – Flexibility: angle encoder modules

Angle encoder modules from HEIDENHAIN are combinations of angle encoders and high-precision bearings that are optimally adjusted to each other. They are characterized by their high degree of measuring and bearing accuracy, their very high resolution, and the highest degree of repeatability. The low starting torque permits smooth motions. Due to their design as completely specified and tested composite components, handling and installation is very simple.

Since HEIDENHAIN manufactures the bearings as well as the encoders, the two functional assemblies are highly integrated. Fewer components are necessary than in conventional solutions, resulting in fewer joints. This permits a very compact and rigid design, with particularly low overall heights. Currently, angle encoder modules with hollow shafts of 35 mm and 100 mm are available.

Angle encoder modules are a combination of bearing and encoder. HEIDENHAIN has already completed the necessary assembly and adjustments. This means that the properties of the angle encoder modules have already been defined and tested according to the customer’s specifications. Simple mechanical interfaces eliminate all critical mounting processes. Not only does this significantly ease the installation, but it also ensures that the specified accuracy is attained in the application. The elaborate matching of all individual components to each other as well as to the machine environment is not necessary, nor is the time-consuming testing.

The angle encoder modules are designed for low to medium shaft speeds and medium loads, with high to very high bearing accuracies as well as the highest degree of repeatability. They are suited to the specific requirements of metrology applications. Typical applications therefore include laser trackers for metrology, high-precision rotary tables in measuring machines, and wafer-handling machines in the electronics industry. They can also be used on machine tools where only slight loads occur, such as on electrical discharge machines or in micro-precision manufacturing.
