CNC Spindle encoder！

Spindle with the spindle encoder uses synchronous optical pulse generator, via the intermediate shaft gear 1: 1 to synchronous transmission. Spindle rotation between the feed movement, not directly linked to the mechanical aspects, in order to process the thread, it is required for a given number of pulses feed servo motor and spindle speed should correspond to the relationship between the spindle from the pulse generator Contact to the effect of the spindle rotation and feed  movement.

Position detecting means is an important part of CNC machine tool servo system. Its role is to detect displacement and velocity, send a feedback signal, closed loop or semi-closed loop control. CNC machining accuracy is mainly determined by the accuracy of the detection system. Different types of CNC machine tools, the maximum moving speed of the position detecting element, precision and detection system unit under test varies. Now the highest level detecting elements and systems are: the maximum moving speed of the tested components up to 240m / min, the displacement detecting resolution (the minimum detectable amount of displacement) of 1 m up to, e.g. up to 0.1 24m / min μm. The highest resolution up to 0.01μm.

CNC machine tools for position detection device has the following requirements:

① little affected by temperature, humidity, reliable, long-term to maintain accuracy, strong anti-interference ability.

② parts in the machine to perform the range of movement, accuracy and speed to meet the requirements.

③ easy maintenance, to adapt the machine working environment.

④ low cost.
