Contouring CNC and encoders speeds EDM
Heidenhain's TNC 416 contouring control system and linear and rotary encoders on a Sparcatron five-axis EDM has eliminated tooling changeover in machining turbine blade bleed holes.
Common applications are in drive technology, robotics and general automation technology.
Most recently, these applications were mainly satisfied with resolvers.
Resolvers are known for their robustness, but they cannot fulfil the demands of drive technology for simpler commissioning, an electronic ID label and diagnostic functions.
Heidenhain's newest inductive rotary encoders, with their inductive scanning principle and well-known EnDat interface, fulfil exactly these requirements, and are even superior to resolvers in terms of positioning accuracy, speed stability and control dynamics.
Also the competitive pricing makes them a welcome alternative to resolvers.
These newest of rotary encoders offer a small overall diameter of 38mm, with a length of less than 28mm.
The new Heidenhain models are ECI 1116 (absolute singleturn encoder with a resolution of 16-bit) and the EQI 1128 (absolute multiturn 16 bit per/rev, 12 bit turns).
The new ECI/EQI rotary encoders are mechanically compatible with the optical variant ECN/EQN 1100 series.
The associated motor non-drive end and the electrical interface remain identical regardless of the choice between optical and inductive encoders, allowing the motor manufacturer to produce a large number of identical parts increasing overall production and lowering production prices.
The same also applies to the subsequent electronics and connecting cables. Request a free brochure from Heidenhain (GB) ...
