Numerical control (NC) has become a relatively mature application technology, and it has been used in various machine tools, including CNC honing machines. Simply put, CNC enables equipment to automatically perform actions by implementing pre-programmed components, thereby completing the production process. It can be considered a type of automation technology.

The CNC application technology of honing machines combines multiple aspects, including mechanics, measurement, computer, automation technology, microelectronics, etc. It also adopts a variety of sensor technologies, including photoelectric encoders, linear gratings, speed sensors, temperature sensors, pressure sensors, Hall sensors, etc. The main purpose of these sensors is to detect parameters such as the position, pressure, temperature, displacement, and speed of the equipment.

CNC machine tool standards for sensors

1) High stability and strong anti-interference ability;

2) Meets accuracy and speed standards;

3) Convenient application, maintenance, and upkeep; suitable for machine tool operating environments;

4) Low cost.

Different types of CNC honing machines use different sensor standards. Most of the time, large equipment uses sensors that require fast response, while medium and high-precision equipment uses sensors that require high accuracy.

In CNC applications, the use of inductive synchros is also very important. The principle of an inductive synchro is that the mutual inductance of two planar windings changes with the position. Its function is to convert angular or linear displacement into the phase or amplitude of induced electromotive force, thereby measuring angular and linear displacement. It can be divided into linear and rotary types, with rotary inductive synchros being more commonly used in die-casting machines.
