CNC machine tools according to the classification of processing categories can be classified
Point control system: point control system refers to the numerical control system only controls the tool or machine table, from a little Huai to move to another point, and points between the movement of the track does not require strict control of the system.
(2), point linear control system: point linear control system refers to the NC system not only control the tool or table from a point to accurately move to the next point, and to ensure that the trajectory between the two points is a straight line
The use of such control systems are mainly CNC coordinate boring machine, CNC drilling machine, CNC punch and so on.
In order to reduce the movement of the moving parts and positioning time, generally first to quickly move to the end of the vicinity of the location, and then accurately move to the end of the low-speed positioning position to ensure good positioning accuracy.
