Technical service for MORI SEIKI machines
In the manufacturing industry, numerically controlled (CNC) machine tools are at the heart of high-precision production. Among the most renowned brands, MORI SEIKI, now part of the DMG MORI group, stands out for the reliability and technological innovation of its lathes and machining centres.
In order to guarantee optimum performance and a long working life, however, it is essential to rely on a specialised technical assistance service, able to intervene quickly in the field and with transversal skills, both mechanical and electronic.
Assistec has been providing qualified technical support on MORI SEIKI machines for more than 25 years, supporting companies with a complete service: from on-site electronic and mechanical assistance to the retrofit of systems, up to the regeneration of MAPPS components and systems.
Let's see in detail what it means to rely on Assistec for assistance on these high-tech machines.
The importance of specialised technical support for MORI SEIKI machines
Assistec's real strength is its field service, guaranteed by a team of experienced technicians who can intervene directly at the customer's plant.
MORI SEIKI machines are designed to operate with high precision and reliability. However, component wear, environmental conditions and intensity of use can affect performance over time. Specialist technical support is essential for:
- Prevent unscheduled downtime: regular maintenance allows potential problems to be identified and resolved before they cause disruptions in production.
- Optimise performance: updating and calibrating systems ensures the highest precision and quality of finished products.
- Prolong machine life: timely and accurate interventions reduce wear and tear and prevent irreversible damage to components.
Assistec technicians work with advanced diagnostic equipment and in-depth knowledge of MORI SEIKI architectures, including FANUC, Mitsubishi and MAPPS CNC systems
Electronic service on MORI SEIKI machines
The electronic fieldwork involves a complete set of controls, measurements and configurations:
- CNC diagnosis: Analysis of electrical signals, verification of CNC modules and electronic troubleshooting on FANUC, Mitsubishi controls and proprietary MAPPS systems.
- Checking wiring and safety circuits: Checking interfaces between CNC and PLC, checking relays, safety circuits, diagnosing signal interruptions, reconfiguring communication channels.
- Backup and restore machine and PLC parameters: Preventive backup of machine parameters and complete restoration of the CNC software in the event of a crash or loss of configuration. Including reinstallation of the MAPPS system.
These interventions allow production to be quickly restarted even in the event of complex faults, drastically reducing downtime.
Mechanical service: overhaul and field repair
Assistec offers advanced mechanical service for MORI SEIKI, carried out directly in the workshop:
- Spindle overhaul: Dismantling, cleaning, bearing replacement, dynamic balancing and vibration testing to ensure precision and reliability.
- Linear guide and runner block maintenance: Cleaning, lubrication, axis clearance check, replacement of worn components.
- Replacement of ball screws: Backlash analysis, replacement of damaged screws and restoration of axial and geometric accuracy.
- Machine alignments: Geometrical check according to ISO standard, correction of linear and angular errors, realignment of axes.
- Tool change maintenance: Check and overhaul of cams and pneumatic or hydraulic actuators, to ensure a smooth and precise tool change sequence.
- Check and replacement of sensors and limit switches: Check and calibration of proximity sensors, pressure switches, encoders. Mapping and synchronisation with numerical control.
With these measures, Assistec helps companies to preserve the precision and reliability of the machine, extending its service life and reducing downtime costs.
Electrical and mechanical retrofit
In many cases, the MORI SEIKI machine is not to be replaced, but to be upgraded. The Assistec retrofit service allows you to:
- modernise numerical control (e.g. switch to newer CNC versions);
- replace obsolete motors, drives and panels;
- adapt the machine to current safety standards.
All this without the investment in a new machine. Retrofitting is particularly advantageous for those with a fleet of machines with a good mechanical structure, but in need of a technological upgrade.
Electronic component regeneration and repair
In addition to field service, Assistec has an in-house workshop for the repair and remanufacture of MORI SEIKI electronic components, including:
- CNC
- Operator panels
- Axis and spindle drives
- Power supplies
- I/O boards
Each component is tested and remanufactured with certified spare parts, and supplied with a warranty of up to 24 months. This service is perfectly integrated with technical support: if the fault requires replacement of the component, the field technician can directly start remanufacturing the part.
Repair and reinstallation of MAPPS systems
MORI SEIKI machines equipped with the MAPPS interface may experience specific faults: system crashes, frozen screens, slowdowns, touch malfunctions or software errors. Assistec provides dedicated support for:
- MAPPS software recovery and reinstallation
- Machine data backup
- Replacement or repair of touch panels
- Correct interfacing between MAPPS and CNC
Again, this can be done directly in the workshop or, if necessary, supplemented with hardware repairs in the laboratory.
The Importance of Digitisation in Technical Assistance
With the evolution of Industry 4.0, digitisation of production and service processes has become essential. DMG MORI has introduced innovative solutions such as the my DMG MORI portal and the NETservice system, which enable:
- Remote machine monitoring
- Remote diagnosis and intervention
- Reduction of machine downtime
Assistec integrates these technologies into its services, offering customers state-of-the-art technical support in line with modern requirements.
