HEIDENHAIN ROD 426 2048 03S12-03 Pulse coder

All of the HEIDENHAIN ROD encoders are tested with Heidenhain PWM Diagnostic tool and Measuring control system to guarantee quality and adjustments of the pulse coders.

All the HEIDENHAIN ROD 426 2048 encoders have a glass. New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory  experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals  are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali oxides and hydroxides, alkaline earth oxides and hydroxides, or boron oxide), or that the impurities are quantified (loss on ignition). CNC-Shopping.com . Evaporation losses during glass melting should be considered during the selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating SeO2. Also, more readily reacting raw materials may be preferred over relatively inert ones, such as Al(OH)3 over Al2O3. Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. HEIDENHAIN ROD 426 2048 Encoder
