Technical Evaluation of the DMG MORI DMC 160 U duoBLOCK
CNC 5-Axis Vertical Machining Center (Year 2017)
1. Technical Evaluation Overview
The DMG MORI DMC 160 U duoBLOCK is a large-format 5-axis vertical machining center built in 2017. The machine features a duoBLOCK structural design, intended to provide high rigidity for heavy-duty and complex machining operations.
The stated axis travels of X 1,600 mm, Y 1,100 mm, and Z 1,400 mm define a substantial working envelope suitable for large components. The table dimensions of 1,250 mm × 1,000 mm support sizable fixtures and workpieces within this envelope.
The machine is configured with a Siemens SL CNC control, a 240-station tool magazine, and SK 50 tool holders, indicating a setup focused on high torque capability, extended unattended operation, and complex multi-tool processes. A 2-pallet system is specified, supporting parallel setup and machining workflows.
Listed equipment includes high-pressure internal coolant (IKZ), a chip conveyor, and a measuring probe, all of which contribute to process stability and in-cycle measurement. No spindle speed, spindle power, rotary axis specifications, or accuracy values are provided.
2. What to Check Before Buying
Given the absence of detailed spindle and rotary axis specifications, inspection should prioritize verification of 5-axis kinematics and overall machine geometry. Linear axis condition should be assessed for smooth motion, positioning consistency, and wear, particularly over the long Z-axis travel.
The rotary/tilting axes associated with the U-axis configuration should be checked for backlash, repeatability, and clamping stability under load, as these directly affect multi-axis accuracy.
The Siemens SL control should be evaluated for alarm history, option activation, software version, and availability of complete parameter and backup files. The 240-tool magazine and tool handling system require functional testing to confirm reliable indexing, tool recognition, and safe operation.
Auxiliary systems such as IKZ, chip conveyor, and the measuring probe should be tested in operation. Probe calibration status and integration with the control should be verified, as functionality depends on both hardware condition and control configuration.
3. Typical Industrial Applications
Based strictly on the provided configuration, this machine is suited for complex, large-scale 5-axis machining tasks involving prismatic and free-form components. Typical applications include aerospace structures, large molds and dies, energy-sector components, and heavy mechanical parts that benefit from multi-face machining in a single setup. Use beyond the stated travels, table size, or tool interface should not be assumed without verification.
4. Common Risks in Used Machines
For used large 5-axis machining centers, common risks include loss of geometric accuracy, particularly in rotary axes, wear in heavily loaded linear guides, and issues within complex tool magazine systems. Control-related risks may involve missing backups, undocumented option changes, or software mismatches. Chip management and high-pressure coolant systems can also suffer from internal wear or blockage if maintenance has been inconsistent.
5. Maintenance and Service Considerations
Maintenance requirements depend strongly on actual operating hours and prior service quality, which are not specified. Regular attention should be given to axis lubrication, rotary axis clamping systems, coolant filtration, and thermal management. The Siemens SL control and probe system require confirmed long-term support, including software updates and spare parts availability.
Given the machine’s size, mass, and system complexity, any major mechanical or alignment service should be carefully planned with appropriate lifting and service resources.
Final Note:
While the machine’s core configuration, travels, and major options are clearly stated, critical information—such as spindle specifications, rotary axis details, accuracy data, and service history—is important. These elements should be verified through documentation review and on-machine testing before forming final technical conclusions.
