Robot-assisted series machining with the DMG Mori Seiki NTX2000
Automated manufacturing processes make a significant contribution to increasing process reliability, reducing manual intervention and ensuring the economic utilization of CNC-controlled machine tools. On the DMG Mori Seiki NTX2000, the SherpaLoader®T20 takes over the complete component handling including alignment, spindle transfer, cleaning and return. The DMG Mori Seiki NTX2000 is equally suitable for rotationally symmetrical blanks as well as molded forgings and castings, and enables consistent machining quality with consistently reproducible clamping conditions.
Reproducible CNC processes thanks to automated component transfer on the DMG Mori Seiki NTX2000
The SherpaLoader®T20 is equipped with two three-jaw centric grippers for reliable component handling. The material is supplied via Table Trolleys, on which the molded cast parts are placed. With the integrated camera-based recognition system, the robot detects the position of the raw parts. This eliminates the need for exact positioning of the raw parts, reducing the amount of preparation work and increasing the degree of automation. The robot arm then grips the first blank with the blank gripper and positions it in an alignment station. There, the rotation of the Part is aligned based on a geometric feature. The preparatory alignment enables a consistent transfer to the MAIN SPINDLE and contributes to repeatable clamping conditions.
Synchronized Mach ining and Safe Clamping Processes on the DMG Mori Seiki NTX2000
Before insertion into the MAIN SPINDLE, the robot automatically cleans the chuck with compressed air. The removal of chips and coolant residues ensures constant component clamping and reduces the risk of positional deviations. Machining of the raw part and semi-finished part then begins synchronously in the main and secondary spindles of the processing machine. After Machining, the SherpaLoader®T20 cleans the finished part in the counter spindle and removes it with the finished part gripper. The robot then leaves the work area, the processing machine closes the machine safety door and transfers the semi-finished part from the MAIN SPINDLE to the counter spindle. The machine then opens the safety door and the robot cleans the clamping device of the MAIN SPINDLE with compressed air and inserts the next raw part into the clamping device. The robot leaves the working area of the processing machine and the NC program of the DMG MORI SEIKI NTX 2000 starts. The finished part is placed back on the Raw Material Staging in parallel to machining time, and the next raw part is already picked up and prepared on the alignment plate. The robot synchronizes its movement with the machine cycle of the DMG Mori Seiki NTX2000. By implementing synchronized processes in the machining process, non-productive times are reduced and the spindle running time is increased. The cyclical repetition of the process ensures an uninterrupted material flow. A fixed protective housing as well as a monitored access door and a light barrier completely safeguard the automated operation and prevent uncontrolled interventions in the ongoing process.
Process reliability and efficiency through automated processes on the DMG Mori Seiki NTX2000
The automated implementation with the SherpaLoader®T20 increases the reproducibility of Machining in the DMG MORI SEIKE NTX2000, reduces the susceptibility to faults in the clamping processes and reduces the need for manual intervention. Constant component clamping, defined transfers and synchronized sequences contribute to high process stability. At the same time, the cost-effectiveness of the process is improved, as cycle times are reduced and machine running times are used more efficiently. Automated component handling thus creates stable production conditions and ensures consistent machining results, even over Lengthwise running times. This facilitates the standardization of processes and relieves the strain on operating personnel in the long term.
