Doosan technical support and turret retrofits: optimise the performance of your machine tool

Doosan CNC machine tools are synonymous with reliability, precision and versatility. Like any production system, however, these solutions require maintenance, upgrades and, in many cases, targeted interventions to extend their operational life and improve their performance. Who to turn to? The Doosan technical support and retrofit service on Doosan turrets offered by Assistec is a real opportunity to optimise production efficiency and ensure maximum safety on the shop floor.

Why work on Doosan turrets?

Turrets represent one of the most stressed components within a CNC lathe. Mechanical wear, vibration and obsolescence of certain parts can compromise machining accuracy and speed. The Doosan turret retrofit allows:

• restore original operating conditions;
• improve the stability and repeatability of tools;
• integrate state-of-the-art automation and control solutions;
• reduce noise and vibration during processing;
• increase the operational security of the system.

To answer the initial question, then, intervening early can significantly reduce downtime, extend plant life and improve the quality of the finished product. Retrofitting is often the more advantageous choice compared to the complete replacement of the turret assembly, both in terms of cost and downtime.

Assistec's specialised services for Doosan machines

Thanks to its experience in automation and CNC maintenance, Assistec offers a complete package of technical services for Doosan machine tools, including:

Complete mechanical assistance

We offer a complete overhaul and repair service for mechanical components subject to wear and tear, including:

• linear guides

• ball screws

• lubrication systems

• motors and servomotors

• spindles

• chip cooling and discharge systems

We intervene directly at the customer's premises or in our fully equipped workshops, with the aim of minimising downtime and ensuring a quick return to production.

Turret retrofit

Our Doosan turret retrofit service includes:

• technical analysis of the turret and its subsystems (indexing motor, gearbox, actuator)
• replacement and/or repair of worn components
• restoration of original operating tolerances
• fine mechanical adjustment and functional testing
• installation of new sensors, encoders or feedback devices
• possible installation of accessories for interfacing with external devices (robots, probes, software)

In specific cases, a partial electrical upgrade of the turret can also be envisaged, with the inclusion of upgraded wiring or devices for predictive diagnostics..

Upgrading of security control units

We can replace and upgrade Doosan machine safety units with solutions that comply with current machine safety standards (e.g. ISO 13849, IEC 62061).

These interventions allow:

• to avoid penalties in the event of inspections;
• to maintain CE certification even after modifications;
• to increase operator protection with more reliable systems;
• to integrate emergency control and axis locking with external PLCs or HMI interfaces.

Integration with external devices and customised software

Another strength of Assistec is the ability to interface Doosan machines with external devices, including:

• machine vision systems
• sensors for dimensional inspection or part inspection
• automatic loaders
• anthropomorphic robots
• energy monitoring and predictive maintenance modules

We develop customised software for machine parameter management, integration with MES or company ERP, and remote monitoring.

Original and compatible spare parts

We have a network of reliable suppliers to offer genuine and compatible Doosan parts, including:

• motors and encoders
• bearings and mechanical assemblies
• valves, actuators and sensors
• electrical and electronic control components

This allows us to reduce waiting times and ensure business continuity for our customers. Quick and punctual supply is a strategic element in our service contracts.

Case study: concrete benefits for the customer

One of our customers, active in the automotive sector, approached us for a turret retrofit and safety control unit upgrade on a Doosan PUMA GT 2600 machine. After an accurate initial diagnosis, we designed and implemented a tailor-made intervention plan, compatible with the customer's production schedule. The work involved overhauling the turret, replacing damaged sensors, updating the PLC software and integrating a remote monitoring system.

As a result of the intervention, the client achieved numerous benefits:

• increased tool change reliability
• reduction in unplanned downtime,
• improvement in overall plant safety,
• greater control and traceability of machining operations.

The advantages of retrofit versus machine replacement

There is often a tendency to consider complete machine replacement as the only solution. However, retrofitting is an economically viable and technically effective alternative:

• Allows the recovery and valorisation of already depreciated assets;
• Requires less investment than buying a new plant;
• Reduces production downtime;
• Makes the machine safe according to the latest regulations;
• Offers greater flexibility in technical solutions.

With Assistec's support, the retrofit becomes a strategic intervention, combining operational efficiency, safety and savings.
