In general, the spindle and the feed of each axis of a CNC machine tool will be driven by their own motors, such as servo motors and stepping motors.
Then there is communication.
Program instruction-system processing, signal transmission-motor rotation, drive screw-screw nut, drive workbench to move.
Transmission weighing is relatively simple.
What are the main motion transmission and feed motion transmission of CNC machine tools that drive chucks? This is the main motion.
It is the feed movement that drives the tool rest to move.
What does the coordinate motion of CNC machine tools mean? What are the feeding movements of CNC machine tools? The coordinate movement of CNC machine tools refers to the movement of servo axes (X axis, Y axis, Z axis, A axis, B axis, C axis, etc.). ).
The feed motion of CNC machine tools includes linear axis motion (X axis, Y axis, Z axis, etc. ) and rotation axis movement (A axis, B axis, C axis, etc. ).
7. What is the main movement and feed movement of CNC lathe? What are the main motion and feed motion of CNC milling machine? Spindle rotation is the main motion, and X.Z axis or X.Y.Z axis is the feed motion.
The difference between machine tool active motion and feed motion: the rotation direction of machine tool spindle is the main motion direction, and the direction parallel or perpendicular to the main motion direction of machine tool is the feed motion, in which the vertical direction is the transverse feed.
How to keep the main movement of NC machine tool synchronized with the cutting feed of tool rest? How to keep the spindle motion synchronized with the cutting feed of the tool rest? Synchronization is only needed when turning threads, and the spindle encoder ensures that each feed is in one position to prevent disorderly threads.
It shows that the main motion and feed motion of grinder are called the main motion with the highest rotating speed and the fastest movement on the machine tool.
Feed movement is the movement needed to make the cutting layer material of the workpiece enter the cutting, so as to process a complete surface.
It can be seen that the main movement on the surface grinder is the high-speed rotation of the grinding wheel.
The feed movement is the movement of the workbench and the downward feed of the grinding wheel.
In cylindrical grinding, the main motion is the high-speed rotation of the grinding wheel, and the feed motion is the radial motion of the grinding wheel.
Rotation of the workpiece.
How to realize the rotary motion of CNC machine tools? The rotary motion of NC machine tool is realized by turntable.
The turntable is provided with a rotatable table top and machine tool accessories for clamping the workpiece and realizing rotation and indexing positioning, which is referred to as the turntable or the fourth shaft for short. Turntable can be divided into general turntable and precision turntable according to different functions.
What is the feed motion of CNC milling machine? The workbench moves horizontally or vertically, and the spindle moves vertically up and down.
How to realize multi-axis linkage of CNC machine tools? If all six surfaces can be machined, there are only four shafts that can really be linked. As far as I know, multi-axis linkage of machine tools does not mean how many axes the machine tool has, but the number of axes the machine tool moves at a time. For example, there is a nine-axis turning and milling compound center in our school, and you can apply for a patent. You can't machine all six surfaces of a workpiece in one clamping, because you always do.
