NEW encoders for high speed spindles
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.
Resolvers vs encoders for motion control
The phrase “more precise control” would generally drive the solution towards an encoder over a resolver. The application of dry food packaging however might tend to drive it back towards a resolver. Here are some characteristics you can consider to help make the decision.
Did you know… – HEIDENHAIN Microlution
DID YOU KNOW...that HEIDENHAIN linear scales are an integral part of a unique micro-machine operation borne of two University of Illinois researchers?
Early warning system for production systems
If small modules in a plant or machinery break down without notice, the costs for the replacement part are usually out of all proportion to the damage caused by the interruption of production. For example, in the paper industry the costs of each hour of interrupted production are on the order of $7000 and more.
Did you know… HEIDENHAIN INGERSOLL
…that North America’s largest five-axis gantry machine is located in Detroit and uses the world’s longest HEIDENHAIN linear scales? Called the CyberMill® by machine builder Ingersoll Machine Tools (www.ingersoll.com) in Illinois, this massive machine has an X-axis that is three quarters the length of a football field and is in operation at W Industries (www.w-industries.net), a leader of metal products manufacturing.
Question: What is a PWM 9?
Answer: The PWM 9 is a complete universal measuring unit for inspecting and adjusting HEIDENHAIN incremental linear and angle encoders.
Linear encoders for production – integrated measuring machines
Up to now, measuring machines have operated in a largely familiar, exactly defined environment, since their performance is significantly determined by the signal quality and accuracy of their linear encoders. Now, with the trend toward production-integrated measuring machines, the measurement device in use should be clearly reviewed.
Torque in servo motors
When specifying servo motors for a new machine or CNC retrofit, there are many specifications regarding servo motor performance. One of the most confusing is the differing torque specifications of the motor. Torque can be specified in Newton meters (Nm) or more commonly foot pounds (lb-ft) or inch pounds (lbf-in).
Inductive rotary encoders for resolver systems with a higher resolution
The inductive rotary encoders of the HEIDENHAIN ExI 1100 series are now available in versions whose mating dimensions are the same as those of common types of resolvers. Depending on the respective applications and accuracy requirements, inductive or optical absolute encoders are now possible as high resolution alternatives to resolvers.
HEIDENHAIN rotary encoders in elevator technology
Every day, millions of people use elevators for transportation. Statistically speaking, every person on the earth rides an elevator once every 72 hours, and everyone considers the availability and reliability of elevators to be a matter of course.
