Numerical control lathe which a few kinds
Low press process USES classificationMetal cutting numerical control machine tool, including the CNC lathe, CNC drilling machine, CNC milling machine, CNC grinding machine, CNC boring and milling machine and machining center.These machines are suitable for single piece and small batch and many varieties and parts processing, has the very good processing size consistency, high productivity and degree of automation, and high flexibility.
Metal forming type of CNC machine tools;This kind of machine tools including CNC bending machine, CNC punch, CNC pipe bending machine, CNC turret press, etc.
Numerical control special machine tools;This type of machine tools including CNC wire (electrode) cutting machine, CNC edm machine, CNC flame cutting machine, CNC laser cutting machine, combination machine tools, etc.
Other types of CNC equipment;The processing equipment adopt CNC technology, such as automatic assembly machine, coordinate measuring machine, automatic drawing machine and industrial robots, etc.
Low classification according to the movement way
Position control;Position control of the characteristics of numerical control machine is a machine tool in the moving parts can be achieved only from one location to another location accurate motion, without any processing in the process of movement and positioning process.Such as number according to the coordinate boring machine, CNC drilling machine, CNC welding machine and CNC pipe bending machine, etc.
Linear control;Point linear control machine tool is the feature of moving parts is not only to realize a coordinate location to another location of moving and positioning precision, and can realize parallel to the axis of the linear feed movement or feed movement control two axes diagonal lines.
Profile control;Profile control the movement of the characteristics of numerical control machine is a machine tool components can realize two axes linkage control at the same time.It not only requires the beginning and end of the machine tool motion control components coordinates, and for every point to control the whole process of speed and displacement, which requires control trajectory, parts processing into the plane of the straight line, curve, or surface in space.
Low according to control methods of classification
Open loop control.That is, don't take position feedback device control mode.
Half closed loop control;Refers to the open loop control servo motor shaft is equipped with angular displacement detection device, by detecting Angle indirectly detect the moving parts of servo motor displacement feedback to the CNC device comparator, compared with the input instruction, using differential control the moving parts.
The closed loop control;Is in the final the corresponding position of the moving parts of machine tool directly linear or rotary detection device, will be directly measured values of displacement or angular displacement feedback to the numerical control device comparator compared with input command shift with differential control the moving parts, making the moving parts in accordance with the actual needs of displacement movement.
