Separated E3TA system (E3TA-PS+EOP-4020TA)
Integrated E3TA System (E3TA PI)
Compact E3TA System (E3TA-PC)
The system uses smooth trajectories to fit the connection positions of line segments based on allowable error parameters, improving corner speed while reducing speed jumps at the connection points, improving processing efficiency, and suppressing the generation of connection marks.
The system calculates the command compensation amount based on the servo gain and compensates it, thereby alleviating the problem of tooth misalignment caused by servo lag, and improving the tooth tapping speed and tooth pitch accuracy.
The system supports three feed axes and two main axes. When adapting to the servo spindle, it can achieve spindle orientation, indexing, rigid tapping, polar coordinate interpolation, X, Y, Z, C-axis interpolation, and other functions, meeting the requirements of turn-milling composite processing.
High speed and high-precision control algorithm and adaptive forward looking speed planning automatically calculate the required number of forward looking program segments, adapt to curvature changes corresponding to speed, limit speed where needed, and ensure higher overall efficiency.
The contour control of linear axis and rotation axis interpolation is realized through the Cartesian coordinate system system editing command. Implemented such as cam machining, workpiece outer diameter milling, irregular workpiece milling, etc
The movement of the rotation axis using the angle command is converted internally to the distance of the straight axis on the outer surface, facilitating linear or circular interpolation with other axes. It can greatly simplify programming for cylindrical surface machining.
The system uses smooth trajectories to fit the connection positions of line segments based on allowable error parameters, improving corner speed while reducing speed jumps at the connection points, improving processing efficiency, and suppressing the generation of connection marks.
For situations where accuracy requirements are not high, the polygon processing function can be used: by changing the speed ratio of the workpiece axis and tool axis and the angle offset before synchronization with the main control axis, various polygons specified by the program can be quickly processed.
Select the handwheel simulation in automatic mode, rotate the handwheel clockwise to execute the program in sequence; rotate the handwheel counterclockwise to execute the program in reverse order. Convenient for users to debug and improve processing technology, providing safety production guarantee.
The page display layout is clear and the content is comprehensive. You don't need to switch pages to understand the operating status of the machine tool.
Open PLC ladder diagram real-time status display, supporting quick search. Provide easy to use PLC editing software, all IO points can be edited, achieving fast and convenient expansion functions.
Insert quick positioning, line positioning, point coordinates, etc. directly into the program through the corresponding menu, eliminating the hassle of inputting coordinates each time. And accurately insert the trajectory based on the actual working coordinate position.
